     TECHNICAL FIELD 
     The present disclosure relates to methods of processing waste, in particular methods for producing synthetic soil from waste. The present disclosure also relates to synthetic soil produced from waste. 
     BACKGROUND 
     The current world population is 7.7 billion. During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion. The average population increase is estimated at 82 million people, a rate of around 1.08%, per year. However, the agricultural land area has been decreasing due to urbanization which has absorbed farmland for commercial, residential and industrial development. To secure more food supply, forestland is converted into cropland which has been excessively exploited or overused with chemical fertilizers and insecticides. The soil related sectors, such as agriculture, forestry and land use, account for approximately 24% of greenhouse gas (GHG) emission. Microbes in contact with chemical fertilizers and natural manure generate nitrous oxide, a major contributor to global warming. 
     Every year we generate 2.12 billion tons of waste globally, including post-consumer, agricultural, and industrial waste. A significant amount of waste is untreated or treated improperly, causing serious pollution and occupying large land areas. For example, an aluminum plant typically produces more than 1 million tons of red mud per year. The red mud is typically stockpiled onsite, resulting in the accumulation of ever-increasing amounts of red mud at the plant site. Between 0.7-2 tons of red mud are produced for every ton of alumina extracted, depending on the composition of the bauxite. The two basic methods of onsite disposal are wet discharge (dumping of the water mud in lakes) and dry stacking (landfill of the dried, thickened red mud). 
     Many of the industrial processes that cause CO 2  emissions also pollute the environment. For instance, heavy metals become concentrated or enriched in many industrial wastes, such as the red mud that is the byproduct of aluminum refining; or fly ash and bottom ash that are the byproducts of coal combustion; or ash from municipal solid waste (MSW) incinerators, where the ash is the byproduct of burned municipal waste. In all of those and other similar waste streams, trace metals are present at the parts-per-million (ppm) level. An environmental burden can be created when these metals leach from ash or red mud containment areas. Most of the metals found in ashes (and in red mud) are toxic, even at low ppm concentration levels. Chemically, such metals are members of all but two groups of the periodic table, with common examples being arsenic, mercury, lead, uranium, vanadium and nickel. This creates special needs for the disposal of fly ashes (and bottom ash and red mud) and establishes a significant environmental burden. 
     In addition, the waste disposal is accounting for approximately 11% of global GHG emission, contributing to global warming. Soil contains organic bodies that change with time, metabolize and ultimately die. As global warming worsens, the soil organic matter (SOM) releases faster and eventually the soil can become a sterile mixture of minerals that fails to support life. 
     Various processes are known for treating waste, including incineration and composting. Composting or recycling waste materials to produce soil-like growing medium or similar products are described in various patents. U.S. Pat. No. 5,312,661 discloses artificial soil made from thermoplastic resin foamed particles, where thermoplastic resin foamed particles and fine substances are bonded to each other by heat fusion of the thermoplastic resin foamed particles to form a porous structure. U.S. Pat. No. 5,192,354 relates to soil substitutes produced from shredded tree bark, quarry stone particles and silica sand particles. Composting is performed by laying out the mixture in windrows and aerating the shredded tree bark by mechanically turning material in the windrows so that composting proceeds within the temperature range of 42-60 degrees Celsius. U.S. Pat. No. 4,050,917 discloses a method of composting wastes by controlling aeration, pH, moisture content and temperature during composting. U.S. Pat. No. 4,369,054 discloses a composition of pulped fibers and slag. U.S. Pat. No. 4,164,405 discloses a method for controlling fungi that utilizes aerobically fermented cotton gin waste. U.S. Pat. No. 6,488,732 relates to plant growth media composed primarily of coffee grounds, along with other commercial and industrial waste materials. 
     However, there are many drawbacks associated with these reported methods. For instance, the composting time is very long, taking months or even years. The decomposition is not complete resulting in additional decomposition of the organic matters by microbes, thus emitting GHG. The resulting artificial soil contains heavy metals and metalloids, pathogens, vectors and weed seeds which are harmful for plants and  rhizobia . Additionally, foams used for binding are not degradable. As no adhesion exists between the soil particles, they can easily be eroded away to pollute rivers and oceans. 
     Other methods for waste treatment include 3R (recycle, reduce and recovery) which however cannot process economically and safely the large quantity of waste generated today. The conventional methods to handle animal manure and liquid waste products from poultry and livestock production facilities do not address some health and environmental concerns. 
     Organic and inorganic waste contains valuable nutrients and there is a need for processing waste to provide useful products. There is also a need for environmentally friendly alternatives to conventional fertilizers for crops. Thus, methods to regenerate soil from waste is urgently needed. 
     The present disclosure provides methods for processing waste to produce synthetic soil. The present methods efficiently convert a large amount of industrial, agricultural and residential waste into synthetic soil that could help lessen acute environmental pollution and global warming. Synthetic soil is extremely important to a sustainable future for all mankind.

     DETAILED DESCRIPTION 
     The present disclosure provides efficient and cost-effective methods for re-mining and converting waste into synthetic soil. The synthetic soil is generated from inorganic waste and organic waste through a hydrolysis-polycondensation process. Inorganic waste may include industrial waste such as fly ash (FA), red mud (RM), phosphogypsum (PG), and ground blast furnace slag (GBFS). Organic waste may comprise municipal solid waste (MSW), agricultural waste (such as agricultural compostable green), animal waste and sewage sludges. Organic waste can be hydrolyzed/extracted by, e.g., activated red mud, to form a biomaterial (e.g., a biosolid sludge), before being mixed with the activated inorganic waste (e.g., a reactive zeolite gel). The ingredients react, set and harden to form a synthetic soil, which is a new complex having geotechnical properties and nutritional values equal, or superior, to existing natural fertile soil. The synthetic soil is formed by a constructive process, unlike natural weathering which is a destructive process. 
     The present disclosure provides for a method for producing a synthetic soil from wastes.

The synthetic soil may act as a moisture-retaining agent to capture and retain water and nutrients. The present synthetic soil may release nutrients to plants over a period of time, for example several months. This means that there is less danger of toxicity to plants and of nutrients running off the land before they are taken up by plants. The present synthetic soil may provide a sustained supply of nutrients through a longer period of the growing season. The synthetic soil can also be a perfect matrix for inoculating diazotrophic bacteria (e.g.,  rhizobia ). 
     The present synthetic soil exhibits properties essential for growth of plants. It has a porous structure and exhibits air permeability, heat insulating, water retention, and nutrient retention. Furthermore, having been treated in an alkaline composition, the synthetic soil contains substantially no phytopathogenic bacteria or eggs of noxious insects and thus protects plants from diseases or noxious insects. 
     In certain embodiments, organic and inorganic wastes are used to produce a heterogeneous polymerized zeolite-encapsulated organometallic complex structures. Soil particles may be bound together by a colloidal force to provide excellent nutrient and water retaining capabilities. 
     In another aspect, the present synthetic soil provides one or more of the following: nourishing the soil in a natural manner, providing a balanced release (e.g., slow and fast release) of nutrients, establishing improved water retention of the soil, improving soil porosity, delivering deeper root penetration of nutrients, or combinations thereof. 
     The present synthetic soil can be useful as, for example, an additive to other products. Similarly, the present synthetic soil can be added or spread onto fields or crops. The present synthetic soil can be incorporated into other agricultural compositions. In a further aspect, the present synthetic soil can be useful for lawn and garden uses. In still further aspects, the present synthetic soil can be used in turf management applications. In still further aspects, the present synthetic soil can be retail packaged for use by consumers. In an even further aspect, the present synthetic soil can be used in professional activities, for example, in horticulture-related activities. 
     The present synthetic soil provides excellent greenhouse gas (GHG) sequestration. A substantial portion (e.g., substantially all) of organic matter in the waste may be solidified and stabilized in the synthetic soil (e.g., in the structure of the soil&#39;s feldspar encapsulated organometallic complex). The present synthetic soil can substitute for synthetic fertilizer or natural manure which are decomposed by microbes to generate powerful GHG such as nitrous oxide (N 2 O), a major contributor to global warming. 
     Besides synthetic soil, the present disclosure also provides other synthetic materials such as synthetic stones (or formula stones). The present methods/systems recover sizable quantities of waste plastics for commercial uses without incurring the secondary emission. 
     The present synthetic soil helps circumvent the usage of chemical fertilizers, vermicompost, insecticides, herbicides and limes, while helping reduce water consumption by at least 50%. Thus, farmers&#39; production costs can be reduced by at least 40%. In addition, the produce can be certified as organic and is safer to consume. 
     Waste is used as raw materials for producing the present synthetic soil. Landfill sites may be a mineral deposit which can be re-mined. Environmental benefits of the present methods and synthetic soil include lessening the need for landfill and waste incineration, as well as restoring water, soil and landscape to conditions meeting environmental protection standards. 
     The present method to produce soil from waste may be performed for a period of time ranging from about 3 hours to about 3 days, from about 4 hours to about 2 days, from about 6 hours to about 1 day, from about 4 hours to about 22 hours, from about 6 hours to about 20 hours, from about 8 hours to about 20 hours, from about 8 hours to about 16 hours, from about 16 hours to about 24 hours, about 2 hours, about 3 hours, about 4 hours, about 5 hours, about 6 hours, about 7 hours, about 8 hours, about 9 hours, about 10 hours, about 11 hours, about 12 hours, about 13 hours, about 14 hours, about 15 hours, about 16 hours, about 17 hours, about 18 hours, about 19 hours, about 20 hours, about 21 hours, about 22 hours, about 23 hours, about 1 day, about 2 days, or about 3 days. The time period may be any one integer value selected from those including and between value points, endpoints inclusive. The time period may be more than 3 days. The time period may be more than 4 days. The time period may be less than 1 day. 
     A significant percentage of heavy metals (e.g., about 90-95%) are absorbed/chelated, making the synthetic soil safe to plants and beneficial microorganisms. Alkaline hydrolysis kills a significant percentage (e.g., greater than or about 80%, greater than or about 85%, greater than or about 90%, greater than or about 95%, or greater than or about 99%) of pathogens, parasites, vectors and weed seeds in the waste, the starting material. 
     The synthetic soil may be designed and tailor-made to meet specific requirements. The synthetic soil may be enriched. In certain embodiments, the present synthetic soil may be enriched with organic matter (e.g., 20 wt % or other weight percentages as described herein), special micro-nutrients (such as 65 ppm of boron (B)), rare earth elements (such as 48 ppm of lanthanum (La) and 136 ppm of cesium (Ce)). The synthetic soil promotes healthy growth for plants, disease resistance and drought tolerance. 
     The synthetic soil can be inoculated with diazotrophic microorganisms (such as bacteria and archaea) that fix atmospheric nitrogen into a more usable form such as ammonia. Examples of diazotrophic microorganisms include  rhizobia, Frankia  and  Azospirillum  (such as  Klebsiella pneumoniae  and  Azotobacter vinelandii ). All diazotrophs contain iron-molybdenum or -vanadium nitrogenase systems.

     The present method for producing synthetic soil from waste may include the steps of pretreating, refining and reforming as described below. 
     Pretreating 
     The pretreating part of the present method may include activating red mud to form activated red mud (e.g., alkali-activated red mud). 
     For pretreating, mixed MSW may be separated/sorted by the float and sink method using activated red mud as a floatation fluid. Grits are heavier and will deposit at the bottom which can be taken out to produce synthetic stones (formula stones). Plastics are lighter and will float on the top which can be taken out (e.g., by rotary screener) for press washing and recovery. Organic fluid can be extracted to a biogeochemical reactor for further processing. 
     Alkali-activated red mud can kill bacteria in the waste, stop the microbial decomposition, and deodorize the waste. 
     The inorganic waste composition may be activated using an alkaline activator. In certain embodiments, the alkaline activator may be sodium hydroxide (NaOH), potassium hydroxide (KOH), sodium silicate (Na 2 SiO 3 ), potassium silicate (K 2 SiO 3 ), or combinations thereof. In one embodiment, sodium silicate (Na 2 SiO 3 ) is anhydrous and/or in a powder form. 
     In one embodiment, sodium silicate (Na 2 SiO 3 ) has the SiO 2 :Na 2 O molar ratio ranging from 0.9:1 to 1.1:1. 
     In one embodiment, the inorganic waste composition includes fly ash (FA) (e.g., about 40-50 wt %), ground blast furnace slag (GBFS) (e.g., about 50-60 wt %), and sodium silicate (e.g., about 4-8 wt %). In one embodiment, the inorganic waste composition is a dry mixture. 
     A catalyst may be added to the reaction. The catalyst may be any suitable agent or composition that is able to increase the rate of reaction. The catalyst may be added in very small quantities, for example in the range of about 0.1 wt % to about 20 wt % of the waste. 
     Refining 
     The refining part of the present method may include organic waste hydrolysis, settling/phase separation, and inorganic waste activating. 
     Organic waste may comprise proteins, fats, carbohydrates, lignocelluloses etc. Organic waste may be hydrolyzed in a hydrolyzing composition such as activated red mud (e.g., alkali-activated red mud) at a basic pH (pH&gt;7) to breakdown organic matter to amino acids (e.g., glysine, lysine, histidine, alanine, serine, proline, tyrosine, tryptophan, leucine, arginine, etc.), humic acid, fulvic acid, sugars, soap, cellulose, lignin, tannin, metallic ions, etc. Pathogens, viruses, vectors, parasites, weed seeds may be destroyed after hydrolysis. 
     The hydrolyzing composition may comprise one or more of the following: red mud (RM), fly ash (FA), ground blast furnace slag (GBFS), sodium hydroxide (NaOH), potassium hydroxide (KOH), and alkali salts. In certain embodiments, Fly Ash (FA) and Ground Blast Furnace Slag (GBFS) may be activated/pretreated to act as a hydrolyzing composition. For example, when the organic waste comprises biosludge, manures, feces, blood meal, bone meal and/or raw bio-material, the chemical reaction between alkali activator with fly ash (FA) and Ground Blast Furnace Slag (GBFS) may generate an internal heat source that kick start the hydrolysis of organic waste almost simultaneously. 
     Alkali salts are salts that are the product of incomplete neutralization of a strong base and a weak acid. Non-limiting examples of alkali salts include sodium bicarbonate (NaHCO 3 ), sodium silicate (Na 2 SiO 3 ), sodium carbonate, sodium acetate, sodium sulfide, sodium percarbonate, potassium bicarbonate (KHCO 3 ), potassium silicate (K 2 SiO 3 ), potassium carbonate, potassium acetate, potassium sulfide, potassium percarbonate, potassium metabisulfite, alkali metasilicates, and alkali metal hydroxides. 
     Red mud is the primary by-product or waste product generated during aluminum oxide extraction from bauxite. The production of aluminum starts with the mining of bauxite ore which is crushed and ground at the aluminum plant to the desired size for efficient extraction of alumina (Al 2 O 3 ) through digestion with hot sodium hydroxide liquor or caustic soda. The hot sodium hydroxide extraction process is more commonly referred to as the Bayer Process. A portion of the liquor that is removed from the alumina in the Bayer process is referred to as “red mud.” After removal of red mud and fine solids from the process liquor, alumina is produced by precipitating aluminum trihydrate crystals and then calcining the crystals in a rotary kiln or fluidized bed calciner. As a result of the Bayer extraction process, the main source of liquid phase alkalinity in the red mud is caustic soda (NaOH). Solid phase alkalinity is derived from species such as calcium aluminates. The highly alkaline sodium hydroxides and sodium carbonates result in pH values ranging from about 9.75 to about 12.56. Common mineral species found in red mud are silicates, the oxides of aluminum, iron and titanium and various calcium and sodium species. U.S. Pat. No. 8,501,125. Iron minerals comprise hematite (Fe 2 O 3 ), a crystalline iron oxide, and usually goethite (FeO(OH)). The aluminum minerals gibbsite (Al(OH) 3 ) and boehmite (gamma-AlOOH) are also very abundant in most red mud. The proportions of amorphous iron and aluminum range from about 0.05% to about 0.22%, and about 0.93% to about 5.02%, respectively. There can be considerable quantities of calcite (CaCO 3 ) and sodalite (Na 8 (Al 6 Si 6 O 24 )Cl 2 ) but this can vary widely. The resistant primary minerals include quartz, zircon and ilmenite (TiO 2 ) and comprise a relatively small proportion ranging from about 6% to about 24%. There can also be minor amounts of heavy metals and radionuclides, most of which are in very stable forms. Depending upon the source and process, red muds can differ considerably in terms of mineralogical composition, and often within the same deposit. Therefore, the mineral composition of red mud varies. In one embodiment, red mud may comprise about 50 wt % water, and about 50 wt % components that are not soluble in sodium hydroxide (e.g., Al 2 O 3 22-28 wt %, Fe 2 2O 3  25-35 wt %, SiO 2  6-16 wt %, TiO 2  8-24 wt %, Na 2 O (total) 4-9 wt %, Na 2 O (soluble) 0.5-0.7 wt %, CaO+MgO 0.5-4 wt %, and LOI 7-12 wt %). 
     Settling/phase separation may include adding a flocculant/coagulant which can induce rapid settling and solid-liquid phase separation. 
     Non-limiting examples of flocculants that can be used in this process include gypsum (CaSO 4 ), phosphogypsum (PG) and/or ordinary Portland cement (OPC, or ordinary cement) powder or fly ash C (with CaO content, e.g., greater than 40 wt %) or combinations thereof. 
     Non-limiting examples of coagulants that can be used in this process include water glass (e.g., sodium silicate solution) which has the SiO2:Na2O molar ratio greater than 2.0, rice husk ash (RHA), moringa oleifera seed powder, pine tree bark powder, chitosan, or combinations thereof. 
     The flocculants and coagulants used in this process are soil friendly materials and may be added to the Formula Soil without causing any negative effect to plants, beneficial bacteria and aquatic environment. 
     In one embodiment, the particles of red mud (RM) and unreacted fly ash (FA), ground blast furnace slag (GBFS) and phosphogypsum or combinations are crosslinked with each other to settle down as a heavy clay matrix and this crosslinking is a part of the process to form the biomaterial. 
     In one embodiment, the biomaterial (from the organic waste composition) deposits at the bottom funnel to be extracted out to the reforming unit. The decanted water is pumped back to the system to mix with activated red mud (ARM) to maintain its activity. 
     The inorganic waste composition may be activated separately by an alkaline activator (in a liquid, e.g., a solution, or dry mixed with the alkaline activator). The inorganic waste composition may be activated to produce a reactive zeolite gel. After mixing with an alkaline activator, the inorganic waste composition can quickly dissolve after reacting with the alkaline activator to form a colloidal zeolite gel. GBFS with high latent hydraulic property reacts both with water and the alkaline activator to release heat which raises the temperature of the immediate surrounding (e.g., to about 45° C. to 60° C. This can kick-start a series of biogeochemical reactions. 
     In certain embodiments, the inorganic waste (not activated by an alkaline activator) can be mixed directly with the biomaterial in a hydrolyzing composition, e.g., in a co-processing manner. 
     The reactive zeolite gel and the biomaterial may be mixed “wet on wet” or “dry on wet”. In one embodiment, the mixing is “dry on wet” and water absorbed to the previously dry fly ash (FA) and ground blast furnace slag (GBFS) helps increase the alkaline reactivity. 
     The biogeochemical reactions (e.g., after mixing the biomaterial with the reactive zeolite gel, for example, step (c)) may take place and last for a period about 10 minutes to about 24 hours, about 20 minutes to about 20 hours, about 30 minutes to about 15 hours, about 40 minutes to about 10 hours, about 10 minutes to about 10 hours, about 10 minutes to about 5 hours, about 10 minutes to about 4 hours, about 10 minutes to about 2 hours, about 10 minutes to about 1 hour, about 20 minutes to about 2 hours, about 20 minutes to about 1 hour, about 10 minutes to about 45 minutes, or about 25 minutes to about 45 minutes. 
     The conversion and speed of reaction may depend on the alkali reactivity, internal heat generation, moisture evaporation and mixing speed. 
     Reforming 
     The reforming part of the present method may be the final stage to yield the synthetic soil. After the reactive zeolite gel is mixed with the biomaterial, a series of physical and/or bio-geochemical processes may take place as described below. 
     In the absorption process, Na in the zeolite (sodalite) may cation-exchange with free metallic ions (Fe 2+ , Ca 2+ , Mg 2+ , Zn 2+ , La 3+ , Y 3+ , Ce + , B 3+ , Cu + , Pb 3+ , As 3+ , Cr 6+ , Cd 2+ , etc.) present in the mixture/blend. 
     In the complexation process, ligands such as amino acids, fulvic and humic acids may enter the zeolite pores (sodalite present in the red mud). Once the ligands enter the zeolite pores, they may chelate with previously exchanged metal ions (Fe 2+ , Ca 2+ , Mg 2+ , Zn 2+ , La 3+ , Y 3+ , Ce + , B 3+ , Cu + , Pb 3+ , As 3+ , Cr 6+ , Cd 2+  etc.) to form zeolite-encapsulated organometallic complexes. 
     New zeolite may form. Amino acids are prevalent in nature and may function as ligands toward the transition metals. Most coordinate to metal ions as N, O bidentate ligands, utilizing the amino group and the carboxylate. They are the “L-X” ligand. Histidine, aspartic acid, methionine, and cysteine sometimes form tridentate H,H,O, N,O,O, S,N,O complexes. Therefore, the organometallic complexes are trapped in the zeolite pores, while it is being built up to form a new zeolite-encapsulated organometallic complexes. 
     The synthetic soil may be further admixed with one or more fillers. The fillers may comprise one or more of the following: biochar, rice husk ash, grounded rice straw, grounded coconut shell fiber, and saw dust. 
     In the polycondensation process, zeolite-encapsulated organometallic complexes and celluloses in a colloidal paste might poly-condense after a filler is added, the pH lowered to below 9, the SiO 2 /Na 2 O ratio increased to greater than 2.2, and water freed. 
     The fillers used in this process may include silica fume (SiO 2 ), biochar, rice husk ash (RHA), phosphogypsum (PG), ground blast furnace slag (GBFS), or combinations thereof. As the reaction proceeds, the pH may decrease to lower than 10. If necessary (e.g., if the pH is lower than pH7.5 or greater than pH9.0), the pH may be adjusted to a desired level between pH7.5-pH9.0. The fillers with pozzolanic property may neutralize the residual caustic soda as well as absorb water to dry up and make the soil softer for easy air circulation. 
     The product of the polycondensation may be a polymeric three-dimensional (3D) network which may be characterized as a heterogenous intergrowth of exogenous feldspars (perthite, anorthite, albite) and fossilized celluloses. 
     In the carbonation process, the residual Ca 2+  in the composition may react with atmospheric CO 2  to form calcite (CaCO 3 ). 
     The present disclosure also provides for a synthetic soil produced by the present methods. Table 3 shows the mineral composition of an embodiment of the present synthetic soil (the F2 sample) analyzed by X-ray powder diffraction (XRD). The amorphous minerals are not detected by XRD.

     In certain embodiments, the synthetic soil contains about 20 wt % organic matter, equivalent to about 11.7 wt % carbon (C) and about 1.17 wt % nitrogen (N), respectively. 1 kg carbon oxidized or decomposed by microbes generates approximately 3.36 kg CO 2 . 1 kg nitrogen oxidized or decomposed by microbes generates approximately 1.57 kg N 2 O. As N 2 O is approximately 298 times more powerful than CO 2 , each ton of Formula Soil produced by the present method can save approximately 5.8 tons of GHG equivalent. 
     Organic matter plays many important roles in the soil ecosystem, which is of importance to sustainable agriculture. The organic matter content is one of the best indicators of soil quality, especially when the soil can be observed over a period of time. The methods of measuring soil organic matter content are well-known in the art and may involve specific equipment. 
     Table 5 shows the physio-chemical properties of an embodiment of the synthetic soil (Formula Soil).

     The synthetic soil may further comprise one or more bio-fungicides, one or more bio-pesticides, one or more bio herbicides, one or more pest control agents and/or one or more unpalatable compounds. Pellets of the synthetic soil may be coated with a coating comprising one or more bacteria, fungal spores, fungicides, pesticides, herbicides, pest control agents, and/or one or more unpalatable compounds. 
     In certain embodiments, in the synthetic soil, all nutrients converted into inorganic-organometallic complexes serve as an “intelligent fertilizer” which releases nutrients at the demand of the plants rather than being decomposed by microbes that generates powerful GHGs, thus making it an excellent carbon sequestration technology. This is achieved by, e.g., encapsulation in the soil and uptake by plants from the atmosphere. Thus, one (1) metric ton of synthetic soil created at least 5.8 metric tons of GHG equivalent CO 2  sequestered directly and indirectly by Clean Development Mechanism (CDM), further serving as a matrix for inoculating nitrogen fixing bacteria, rendering the use of synthetic fertilizer and natural manure obsolete. 
     In certain embodiments, in the synthetic soil, super micronutrient elements such as boron (B), molybdenum (Mo), cobalt (Co), copper (Cu), zinc (Zn), rare earth metals (La, Ce) are ready enriched by chelation or cation exchange into the soil formula during the manufacturing process, unlike the impregnation method in making the growth stimulant fertilizers. The super micro nutrient elements may support the healthy growth of plants and/or inhibit the growth of pathogens, vectors, helping plants to combat diseases better, serving as the passive agro pharmaceuticals, without using insecticides or herbicides. 
     The synthetic soil may act as a buffer material in regulating the soil pH, neutralizing the soil acidity, salinity, detoxicating the contaminants and retaining soil moisture and nutrients by a flexible absorption-desorption mechanism thus making it a multipurpose soil conditioner. 
     Lanthanum (La) and cesium (Ce) are light rare earth elements finding useful application in micronutrient fertilizer that helps to:
         increase photosynthesis of plant&#39;s leaves from 20-80% and the crop&#39;s yield from 10-20%;   reduce the use of conventional fertilizer;   increase the cation exchange, macro nutrient absorption capacity to reduce the synthetic fertilizer consumption;   increase root development to increase the drought tolerance;   increase the resistance to plant&#39;s diseases and insects enable a healthy growth of plants;   less toxicity, rare earth residue is not much different with the crossed references;   increase the agricultural product&#39;s typical flavors and tastes.   increase the seed&#39;s germination, shoot elongation and fruit bearing, sugar content.       

     Boron (B) is a micronutrient critical to the growth and health of all crops. It is a component of plant cell walls and reproductive structures. It is a mobile nutrient within the soil, meaning it is prone to movement within the soil. 
     Zinc (Zn) is one of the eight essential micronutrients. It is needed by plants in small amounts yet crucial to plant development. In plants, zinc is a key constituent of many enzymes and proteins. It plays an important role in a wide range of processes, such as growth hormone production and internode elongation. 
     Copper activates some enzymes in plants which are involved in lignin synthesis and can be essential in several enzyme systems. It is also required in the process of photosynthesis, is essential in plant respiration and assists in plant metabolism of carbohydrates and proteins. 
     Cobalt (Co) is a trace element in plants. It is a component of a number of enzymes and increases the drought resistance of seeds. In legumes, cobalt is important for nitrogen fixation by the bacteria that are associated with legumes. 
     Molybdenum (Mo) is an important trace element for plants because it is an essential component of the enzyme nitrogenase, which helps convert atmospheric nitrogen into ammonia, molybdenum powder is used as fertilizer for some plants, such as cauliflower. 
     The waste may be an industrial waste, an agricultural waste, a human municipal waste, fertilizers, domestic sewage, and industrial effluents. 
     Inorganic waste (or inorganic waste composition) may comprise, for example, fly ash (FA), bottom ash, ground blast furnace slag (GBFS), red mud (RM), phosphogypsum (PG), etc. or combinations thereof. As used herein, the terms “inorganic waste” and “inorganic waste composition” are interchangeable. 
     The term “ash” may refer to fly ash, bottom ash and all types of alkali-containing ash from any source including, but not limited to, coal burning, wood burning and other biomass burning. 
     In addition, waste may include materials which are not derived from combustion, including, but not limited to, other types of ashes, contaminated soils, sewage sludge materials. 
     Organic waste (or organic waste composition) may comprise municipal solid waste (MSW), animal waste (e.g., animal by-products), agricultural waste, vegetable waste, sewage sludge, vegetable waste, food waste, or combinations thereof. Organic waste may comprise, for example, waste from abattoirs, waste from meat processing or packaging, fallen stock, animal carcasses, food waste, animal excrement, for example, cow slurry, pig or cow dung, poultry litter, animal bedding, waste from the food industry, abattoir blood etc., or combinations thereof. Organic waste may comprise waste selected from the group consisting of food scraps, meat, dairy and vegetable matter. Organic waste may comprise animal waste, vegetable waste or mixed animal and vegetable waste. Organic waste may comprise biowaste from sources, including, but not limited to, food waste, produce waste, discarded plant harvest matter (leaves and stalks), animal manure, etc. While not intended to be limiting, organic waste can comprise or be derived from plant and/or animal byproducts, seaweed, dairy product waste, livestock manure, liquid manure, worm castings, peat, guano, compost, blood meal, bone meal, fish meal, decomposing crop residue, cheese whey, mixed liquor from food and/or livestock processing facilities, wastewater from food processing operations, and any combination thereof. As used herein, the terms “organic waste” and “organic waste composition” are interchangeable. U.S. Pat. Nos. 10,000,428 and 10,351,482. 
     Animal waste may include animal by-products, dead animal bodies and portions thereof, as well as animal excreta. 
     During the processing of animals for meat production or other uses, relatively large amounts of the animal are removed, discarded and not sold on to an end user. Animal waste includes animal by-products such as bone, blood, gut content, wool, fur and feathers for example. Animal by-products also include animal waste such as chicken-litter, cow slurry and pig or horse manure. Animal waste may comprise feces, urine, food, bedding materials, such as wood chips and/or sawdust, feathers, and other materials. In one embodiment, animal waste may contain one or more harmful microorganisms, such as bacteria, viruses, protozoa, and/or other parasites or pathogens. Animal excreta include, but are not limited to, manure, which may be feces, urine, and added products such as water, wasted feed, hair, and bedding for the animals. The manure may come from any animal source, such as pigs, poultry (e.g., chickens, turkey etc.), cows, sheep, goats, hogs and horses, even humans. 
     Manure excreted by poultry and other livestock typically contains a variety of pathogens, including  Salmonella , Coliform, Fecal Coliform, Soil Transmitted Helminths (hookworm,  Ascaris , and whipworm),  Campylobacter , Avian Influenza,  Histoplasma, Capsulatum  Fungus, and  Escherichia coli . The presence of these pathogens poses health risks to farm workers handling the manure. In addition, the use or distribution of manure containing these pathogens on agricultural crops can pose health and environmental concerns to farm workers and consumers. 
     Animal waste can be provided from an on-site facility or can be delivered, for example, in bulk quantities by truck. It should also be understood that the properties, for example, the nutrient content and physical properties of a given animal waste product can vary depending upon, for example, the type of animal and/or rearing or growth facility, length of time the animal waste has been stored, environmental conditions, etc. In one aspect, properties, such as, for example, nitrogen content, phosphorus content, potassium content, calcium content, sulfur content, boron content, magnesium content, molybdenum content, sodium content, manganese content, zinc content, iron content, copper content, moisture, and pH, can vary depending upon the type of animal and/or rearing or growth facility. For example, poultry litter animal waste can contain wood chips, sawdust, feathers, and/or other materials in addition to feces, and the moisture content can vary depending upon whether the litter originated in a broiler or egg-laying facility. Poultry litter can comprise a variety of materials of varying size. 
     Vegetable waste may include kitchen waste, bedding from animals, fruit or vegetable processing waste, for example, fruit peels, sugar cane waste. 
     As used herein, the term “about” as a modifier to a quantity is intended to mean±10% inclusive of the quantity being modified. 
     As used herein, the percentage “% (w/w)” or “wt %” is percent weight to weight; the percentage “% (w/v)” is percent weight to volume (w in gram and v in milliliter); the percentage “% (v/v)” is percent volume to volume. 
     The term “substantially free” of an agent should be understood as meaning free of the agent, or that any amount of the agent present in the composition (e.g., synthetic soil) is so low so as not to have any effect on the function of the composition (e.g., synthetic soil), on the outcome of usage of the composition (e.g., synthetic soil) or on the properties of the composition (e.g., synthetic soil) after it is taken out of the composition. In certain embodiment, the term “substantially free” of an agent means that the agent is less than about 5% w/w (or % w/v, or % v/v), less than about 4% w/w (or % w/v, or % v/v), less than about 3% w/w (or % w/v, or % v/v), less than about 2% w/w (or % w/v, or % v/v), less than about 1% w/w (or % w/v, or % v/v), less than about 0.5% w/w (or % w/v, or % v/v), less than about 0.2% w/w (or % w/v, or % v/v), less than about 0.1% w/w (or % w/v, or % v/v), less than about 0.05% w/w (or % w/v, or % v/v), less than about 0.02% w/w (or % w/v, or % v/v), or less than about 0.01% w/w (or % w/v, or % v/v) in the composition (e.g., synthetic soil). 
     The present invention may be better understood by reference to the following non-limiting examples, which are presented in order to more fully illustrate the preferred embodiments of the invention. They should in no way be construed to limit the broad scope of the invention. 
     EXAMPLES 
     Example 1: Preparing Formula Soil from Animal Manure 
     Step 1: Preparing for Precursors Materials and Feeds 
     
         
         
           
             Cow dung: (organic waste) 20 liters 
             Activated red mud solution: 5 liters or 5 kgs by dry weight. 
             (The activated red mud was prepared as described herein. It can be used for purging of bad odors emitted by microbes in animal manure and sewage.) 
             Fly ash (inorganic waste): 20 liters 
             Ground Blast Furnace Slag (inorganic waste): 15 liters 
             Coconut fiber: 20 liters 
             Rice Husk Ash: 10 liters 
             Phosphogysum: (inorganic waste) 10 liters 
             River sand: 20 liters 
             Basaltic soil: 20 liters 
             Sodium Hydroxide: 1 kg 
             Sodium Silicate or water glass: 4 litres (concentration about 1-3 wt %) 
             (Water glass with the SiO 2 :Na 2 O molar ratio ranging from 2.9 to 3.2 can be used. When NaOH was added, the total [Na 2 O+SiO 2 ] increased which reduced the SiO 2 :Na 2 O molar ratio towards more basic (more alkaline). When more NaOH was added, the SiO 2 :Na 2 O molar ratio further decreased to lower than 1.45. In one embodiment, the SiO 2 :Na 2 O molar ratio may decrease to about 0.9:1 to about 1.1:1, at which point it can become an alkaline activator.) 
           
         
       
    
     Step 2: Mixing of Materials Using a 150 Liters Planetary Concrete Mixer 
     
         
         
           
             Soaking cow dung into activated red mud to deodorize the odors. The complete deodorization was for about 1 to 2 minutes indicating that the cow dung has been totally hydrolyzed. 
             Adding 10 liters of water 
             Mixing fly ash, ground blast furnace slag, sodium hydroxide and sodium silicate with the hydrolyzed cow dung (biomaterial) for 30 to 45 minutes to yield a thick and viscous paste. Sodium hydroxide and sodium silicate can react to form a strong alkaline activator with the SiO 2 :Na 2 O molar ratio ranging from about 0.9:1 to about 1.1:1 to hydrolyze the cow dung, fly ash and ground blast furnace slag at the same time. All the mixing was carried out at an ambient temperature. 
             The hydrolyzing of the organic waste was performed at a pH ranging from about pH13 to about pH14. The activating of the inorganic waste was performed at a pH ranging from about pH13 to about pH14 (e.g., about pH14). 
           
         
       
    
     Step 3: Reforming Soil: 
     
         
         
           
             Adding coconut fiber and rice husk ash to the mixture in Step 2, and mixing well for 15-20 minutes. Rice Husk Ash containing chiefly SiO 2  can react with residual NaOH to form additional Na 2 SiO 3 , causing pH to drop to lower than pH 9. The NaOH concentration after mixing and reaction taking place can decrease to about 0.001 to 0.01 wt % or to almost 0 wt %. Then the composition began to polymerize, and the Formula Soil was being reformed. 
             Adding Phosphogypsum and mixing well for 15-20 minutes. CaSO 4  will react with residual Na 2 SiO 3  to form CaSiO 3  and Na 2 SO 4 , thus the concentration of Na 2 SiO 3  (dropped to almost 0.0 wt %. 
             Adding Basaltic soil and mixing well for 15-20 minutes. 
             Adding river sand and mixing well for 15-20 minutes. 
             Adding 1 kg Portland cement to dry up the Formula Soil composition. 
           
         
       
    
     Example 2: Preparing Formula Soil from MSW 
     The MSW contained food waste and compostable greenery. 
     Step 1: Preparing for Precursors Materials and Feeds 
     
         
         
           
             MSW: 20 liters 
             Fly ash: 20 liters 
             Ground Blast Furnace Slag: 15 liters 
             Coconut fiber: 20 liters 
             Rice Husk Ash: 10 liters 
             Phosphogypsum: 10 liters 
             River sand: 20 liters 
             Basaltic soil: 20 liters 
             Sodium hydroxide: 1 kg 
             Sodium silicate: 4 liters (concentration about 1-3 wt %) 
           
         
       
    
     Step 2: Mixing of Materials Using a 150 Liters Planetary Concrete Mixer 
     
         
         
           
             Mixing MSW with fly ash, ground blast furnace slag, sodium hydroxide and sodium silicate well together for 30 to 45 minutes to yield a thick and viscous paste. Sodium hydroxide and sodium silicate acted as both the hydrolyzing composition for the organic waste and the alkaline activator for the inorganic waste. Sodium hydroxide can react with sodium silicate or water glass to form a strong hydrolyzing composition/alkaline activator with the SiO 2 :Na 2 O molar ratio ranging from about 0.9:1 to about 1.1:1 to hydrolyze both the organic waste (MSW) and inorganic waste (fly ash and ground blast furnace slag) at the same time. All the mixing was carried out at an ambient temperature. The hydrolyzing of the organic waste was performed at a pH ranging from about pH13 to about pH14. The activating of the inorganic waste was performed at a pH ranging from about pH13 to about pH14 (e.g., about pH14). 
           
         
       
    
     Step 3: Reforming Soil: 
     
         
         
           
             Adding coconut fiber and rice husk ash to the mixture in Step 2, and mixing well for 15-20 minutes. Rice Husk Ash containing chiefly SiO 2  can react with residual NaOH to form additional Na 2 SiO 3 , causing pH to drop to lower than pH 9. The NaOH concentration after mixing and reaction taking place can decrease to about 0.001 to 0.01 wt % or to almost 0 wt %. Then the composition began to polymerize, and the Formula Soil was being reformed. 
             Adding Phosphogypsum and mixing well for 15-20 minutes. CaSO 4  will react with residual Na 2 SiO 3  to form CaSiO 3  and Na 2 SO 4 , thus the concentration of Na 2 SiO 3  dropped to almost 0.0 wt %. 
             Adding Basaltic soil and mixing well for 15-20 minutes. 
             Adding river sand and mixing well for 15-20 minutes. 
             Adding 1 kg Portland cement to dry up the Formula Soil Composition. 
           
         
       
    
     Example 3: Making Formula Stone for Use as Curbstones 
     Step 1: Preparing the Precursor Material 
     
         
         
           
             Fly ash: 20 kgs dry weight 
             Ground Blast Furnace Slags: 20 kgs dry weight 
             Wetted Coarse aggregates: 30 liters 
             Metasilicate anhydrous: 3.2 kgs 
             Water glass: 2 liters (sodium silicate concentration: about 1-3 wt %) 
           
         
       
    
     Step 2: Mixing Device: 150 Liters Planetary Type Mixer 
     
         
         
           
             Mixing Fly ash, Ground Blast Furnace Slag and wetted coarse aggregate together and mixing well for about 30 minutes for homogenization. 
             Spraying water to the mixture to reach a moisture content of about 15-20%. 
             Mixing metasilicate anhydrous (with the SiO 2 :Na 2 O molar ratio ranging from about 0.9 to 1.1) with the dampened mixture. Mixing well for about 30 minutes. The metasilicate/Fly ash weigh ratio is about 16:100. 
             As a result, metasilicate anhydrous absorbs moisture to form a strong alkaline activator to hydrolyze the Fly ash to produce a zeolite gel to free more water for total dissolution of metasilicate anhydrous powder and Ground Blast Furnace Slag hydrate to generate an internal heat source to kick start the geopolymerization process. 
           
         
       
    
     Step 3: Compressing Device: 80-Ton Compressor for Concrete Brick Making Machine. 
     
         
         
           
             Spraying the mold with water glass 
             Inserting the welded wire messes for reinforcement to increase the flexural strength of the stone body. 
             Filling in the mold with the dampened mixture from Step 2. 
             Compressing the dampened mixture with pressure, causing high intensity friction forces to drive the water outward and to facilitate the chemical reactions as the solid particles became denser and more compacted and bonded together stronger by the zeolite gel. 
             Transferring the formed stone to the hot steam chamber for curing for about 8 hours. The material set and hardened in about 6 to 28 days to reform the synthetic stone. 
             In another method, the formed stone was transferred to a 600 w Microwave Chamber for curing in about 3-6 minutes. The material set and hardened in about 15 to 30 minutes to reform the synthetic stone. 
           
         
       
    
     Example 4: Making Formula Stone for Use as Super-Sized Rock Blocks 
     Step 1: Preparing the Precursor Material 
     
         
         
           
             Fly ash: 50 kgs dry weight 
             Ground Blast Furnace Slags: 50 kgs dry weight 
             Welded wire messes in the form of a gabion filled with rock fragments, pebbles, gravels, glass bottles with size ranging from about 5 cm×5 cm to about 10 cm×20 cm. 
             Metasilicate anhydrous: 8 kgs 
             Waterglass: 4 liters (with the SiO 2 :Na 2 O molar ratio of about 3.2) (sodium silicate concentration: about 1-3 wt %) 
             Aggregates: 200 liters (rock fragments, pebbles, gravels, glass bottles with size ranging from 5 cm×5 cm to about 10 cm×20 cm.) 
           
         
       
    
     Step 2: Mixing in 150-Liter Planetary Type Mixer 
     
         
         
           
             Mixing Fly ash, Ground Blast Furnace Slag together and mixing well for 30 minutes for homogenization. 
             Spraying water to the mixture to reach a moisture content of about 30%. 
             Mixing Metasilicate anhydrous with the dampened mixture, mixing well for about 30 minutes. The metasilicate/Fly ash weigh ratio is about 16:100. 
             Adding water glass and mixing well for 10 minutes to yield a high flow fluid. 
           
         
       
    
     Step 3: Casting 
     
         
         
           
             A watertight mold was prepared to avoid fluid leak. Concrete pump was used for quick delivery of the fluid into the mold. 
             The fluid-like gel filled in the void inside the gabion and was quickly self-compacted, set, cured, hardened, binding the aggregates, rock fragments, pebbles, gravel and wire meshes together in about 6 to 28 days to reform the rock block. As the pH of the zeolite gel dropped to below pH9, the gel polymerized. After curing, the material set and hardened. The concentrations of Metasilicate Anhydrous and Sodium Silicate or water glass reduced to close to 0 wt %.
