Waste-Glass Recycling Plant
Waste glass is not just waste, but a new resource. Supersoil is an artificial light porous foamed material that is made by crushing, milling, baking and foaming waste
glass. The Waste-Glass Recycling Plant is a plant for recycling waste glass produced in the local community into Supersoil.

You just need to place waste glass bottles into the hopper. The Waste-Glass Recycling Plant automatically crushes them and performs milling, sorting and baking toproduce Supersoil.

Outline
The Waste-Glass Recycling Plant is a set of machines to produce Supersoil, a pumice-like light porous foamed material, from waste glass produced in the local
community as 99% of its basic materials.

The Waste-Glass Recycling Plant consists of 9 machine units, a bottle supply hopper, a bottle conveyor, a crusher, a cullet mill, powder conveyors, a powder sifter, amixing machine, a baking machine and a Supersoil sizer; and automatic control panels. The bottle supply hopper can hold about 4.5 m 3 of waste glass, which is crushed
into cullet of less than 6 mm in size by the crusher. The cullet is then milled into glass powder with a median grain diameter of 35 µm by the cullet mill. The glass
powder is sent to the powder sifter, which removes foreign objects and powder grains that are not of a specified size. The mixing machine mixes glass powder andadd-in materials, and continuously sends the resulting powder mixture to the baking machine. There the powder mixture is preheated, softened, baked and foamed in
the temperature range of 700 ~ 920 degrees centigrade. The layer of glass powder mixture having an initial thickness of 15 mm is converted into a light porous slab
having a thickness of about 60 mm. More than 70% of these machines have originally been developed by Trim.

Most conventional glass recycling machines crushes glass only into cullet. The resulting cullet is used for making glass again if it is transparent or brown, and othercullet is mixed in secondary concrete products, asphalt paving and blocks. The cullet, however, is low-value-added products, and its use in business is limited. On theother hand, Supersoil, produced by the Waste-Glass Recycling Plant, has a wide range of application, such as a light embanking material in civil engineering, a culture
medium or an inorganic soil amendment in horticulture and agriculture, a purification material in water purification and an insulator in architecture. It is now used invarious areas for various purposes.

Production Stages and Machine Units-1-Bottle Supply Hopper

The bottle supply hopper can hold about 4.5 m 3 (3.5 t) of waste glass bottles, and the vivratory feeder attached to the hopper bottom supplies glass bottles stably tothe conveyor.

Crusher

Waste glass bottles carried in by the conveyor are crushed in a single process into cullet less than 6 mm in size (the specified grain size of the crusher) by a compact
crusher having a diameter of 1,600 mm.
Glass bottles are compressed and crushed by rollers, which is based on the mechanism of the mill. To improve the wear resistance of the machine, special steel is used
for the inner parts, and removable couplings are used for the inner structure. As a result, our crusher has better wear resistance and durability than ordinary glass
crushers. (Patented)

Cullet Mill

Glass cullet of less than 6 mm in size produced by the glass crusher is further milled to produce galss powder. Our cullet mill is a tube mill modified for glass cullet. Its
inlet can easily take in glass pieces of different sizes and shapes, and its outlet discharges glass powder in the order of smaller specific gravities. The produced glass
powder is separated from paper, such as bottle labels, by a rotary sieve within the two-layer hopper. The cullet mill contains many alumina balls, which collide witheach other to mill cullet. The machine requires no maintenance for about 2 years. The full-automatic operation of the cullet mill synchronized with the glass crusher
enables a continuous production of glass powder, and has achieved a stable glass powder production of the specified grain size and a higher production efficiency(more than 97%).

-2-Powder Sifter

Glass powder produced by the cullet mill is sorted according to grain sizes, and powder of the specified grain size is taken out.
Connection with a powder conveyor allows the continuous sorting of powder. In addition, because of its closed system, no powder is released into the surroundingenvironment.

Powder Conveyors

Powder conveyors transfer glass powder from the cullet mill, the powder sifter, and the mixing machine.
These are spinflow conveyors based on the principle of whirlpools. They allow full-automatic, stable powder transfer, while powder transfer was considered difficult
before. Furthermore, since they do not use air flow, the generation of static electricity is low, and no dust is released into the work environment.

Mixing Machine

Glass powder sorted out by the powder sifter and two types of patent protected chemicals are automatically measured and mixed. These materials. which are different
in quantity, specific gavity and shape, are thus uniformly mixed.
The mixing machine is of sequential batch type and can produce 350 kg of powder mixture in a batch process. In addition, the whole process of feeding, measuring andadding the two types of foaming materials is fully automated, allowing the stable production of glass powder mixture in uniform quality.

Baking Machine

Powder mixture produced by the mixing machine is baked to make a light porous foamed material, or Super soil. The baking
machine consists of a baking section and an annealing section, each of which has a light, insulating and fireproof sructure. Themachine also has a wire-mesh belt conveyor to allow continuous baking.
Furthermore, the baking machine is equipped with 16 burners to carry out the processes of preheating, softening, baking andfoaming.

Supersol Sizer

Produced Super soil blocks are broken and sorted into specified sizes.
The breaker has breaking blades whose shape and material have been specifically designed for Super soil production, allowing
efficient breaking and sorting.

-4-Characteristics

Super soil is perfectly recyclable, from the soil and back to the soil.

Even when Super soil is compacted, it retains good water drainage. Its high water permeability, water retentivity and air permeability promote plant growth.

Super soil is an inorganic mineral and fire-resistant.

Super soil can be made to have different specific gravities depending on its use.

It is possible to produce Supersol having different characteristics by changing the types of add-in materials, milling conditions and baking conditions.

Supersoil is adaptable to various application conditions, such as a place of complex topography or where there are underground pipes. It is easy to handle, and can behandled even in the rain.

•* Very light•* Easy to handle as a banking material and can be applied in ordinary procedures.

•* Does not need curing.

•* Since Supersoil is made from glass, no harmful substance is dissociated from it. Thus, it is very safe to the environment.

•* Since Supersoil is an inorganic mineral, it is chemically stable and does not corrode.

-5-How It Was Developed
Supersoil production technology was developed by the Kishimoto International Technology Institute under the "Research and Development Business Cooperation
Contract" signed in February 1997 with the Clean Japan Center" (CJC) as a project to which a supplementary budget was granted in 1996 by the Ministry ofInternational Trade and Industry (currently the Ministry of Economy, Trade and Industry) and which was entrusted to CJC by the New Energy and Industrial
Technology Development Organization (NEDO) as a verification test of glass cullet recycling.
Based on the result of this project, Trim Co., Ltd. developed a Supersoil production system (plant) for practical use. Today, Trim has built the plants arround Japanand is promoting community vitalization through recycling.
