User: Have you ever wondered how people get chocolate from? In this article well enter the amazing world of chocolate so you can understand exactly what youre eating.
Chocolate starts with a tree called the cacao tree. This tree grows in equatorial regions, especially in places such as South America, Africa, and Indonesia. The cacao tree produces a fruit about the size of a small pine apple. Inside the fruit are the trees seeds, also known as cocoa beans.The beans are fermented for about a week, dried in the sun and then shipped to the chocolate maker. The chocolate maker starts by roasting the beans to bring out the flavour. Different beans from different places have different qualities and flavor, so they are often sorted and blended to produce a distinctive mix. Next, the roasted beans are winnowed. Winnowing removes the meat nib of the cacao bean from its shell. Then, the nibs are blended. The blended nibs are ground to make it a liquid. The liquid is called chocolate liquor. It tastes bitter. All seeds contain some amount of fat, and cacao beans are not different. However, cacao beans are half fat, which is why the ground nibs form liquid. Its pure bitter chocolate.

Recycling is a collection, processing, and reuse of materials that would otherwise be thrown away. Materials ranging from precious metals to broken glass, from old newspapers to plastic spoons, can be recycled. The recycling process reclaims the original material and uses it in new products.In general, using recycled materials to make new products costs less and requires less energy than using new materials. Recycling can also reduce pollution, either by reducing the demand for high-pollution alternatives or by minimizing the amount of pollution produced during the manufacturing process.Paper products that can be recycled include cardboard containers, wrapping paper, and office paper. The most commonly recycled paper product is newsprint. In newspaper recycling, old newspapers are collected and searched for contaminants such as plastic bags and aluminum foil.The paper goes to a processing plant where it is mixed with hot water and turned into pulp in a machine that works much like a big kitchen blender. The pulp is screened and filtered to remove smaller contaminants. The pulp then goes to a large vat where the ink separates from the paper fibers and fl oats to the surface. The ink is skimmed off, dried and reused as ink or burned as boiler fuel. The cleaned pulp is mixed with new wood fibers to be made into paper again.Experts estimate the average office worker generates about 5 kg of wastepaper per month. Every ton of paper that is recycled saves about 1.4 cu m (about 50 cu ft) of landfill space. One ton of recycled paper saves 17 pulpwood trees (trees used to produce paper).

What is photosynthesis? Photosynthesis is a food-making process that occurs in green plants. It is the chief function of leaves. The word photosynthesis means putting together with light. Green plants use energy from light to combine carbon dioxide and water to make sugar and other chemical compounds.How is the light used in photosynthesis?
The light used in photosynthesis is absorbed by a green pigment called chlorophyll. Each food-making cell in a plant leaf contains chlorophyll in small bodies called chloroplasts. In chloroplast, light energy causes water drawn form the soil to split into hydrogen and oxygen.What are the steps of photosynthesis process?
Let me tell you the process of photosynthesis, in a series of complicated steps, the hydrogen combines with carbon dioxide from the air, forming a simple sugar. Oxygen from the water molecules is given off in the process. From sugar together with nitrogen, sulphur, and phosphorus from the soil-green plants can make starch, fat, protein, vitamins, and other complex compounds essential for life. Photosynthesis provides the chemical energy that is needed to produced these compounds.

Human body is made up of countless millions of cells. Food is needed to built up new cells and replace the worn out cells. However, the food that we take must be changed into substances that can be carried in the blood to the places where they are needed. This process is called digestion.The first digestive process takes place in the mouth. The food we eat is broken up into small pieces by the action of teeth, mixed with saliva, a juice secreted by glands in the mouth. Saliva contains digestive juice which moisten the food, so it can be swallowed easily.From the mouth, food passes through the esophagus (the food passage) into the stomach. Here, the food is mixed with the juices secreted by the cells in the stomach for several hours. Then the food enters the small intestine. All the time the muscular walls of the intestine are squeezing, mixing and moving the food onwards.In a few hours, the food changes into acids. These are soon absorbed by the villi (microscopic branch projections from the intestine walls) and passed into the bloodstream.

A natural disaster is a terrible accident, e.g. a great flood, a big fire or an earthquake. It usually causes great suffering and loss of a large sum of money. The casualties are injured or died. Some people are homeless and need medical care.Floods occur when the water of rivers, lakes, or streams overflow their banks and pour onto the surrounding land. Floods are caused by many different things. Often heavy rainstorms that last for a brief can cause a flood. But not all heavy storms are followed by flooding. If the surrounding land is flat and can absorb the water, no flooding will occur. If, however, the land is hard and rocky, heavy rain cannot be absorbed. Where the banks are low, a river may overflow and flood adjacent lowland.In many part of the world flood are caused by tropical storms called hurricanes or typhoons. They bring destructive winds of high speed, torrents of rain, and flooding. When a flood occurs, the destruction to surrounding land can be severe. Whole villages and towns are sometimes swept away by water pouring swiftly over the land. Railroad track blocked and uprooted from their beds. Highways are washed away.When a building caught fire, the firemen pitched in to help battle the blaze. Before the pumps were invented, people formed bucket brigades to fight fires. Standing side by side, they formed a human chain from the fire to nearby well or river. They passed buckets of water from to hand to be poured on the flames.The damage of the fire did depend a great deal on where it happened. In the country or a small village, only a single house might burn down. But in crowded cities, fire often destroyed whole blocks and neighborhoods before being controlled.

Biodiesel is a clean burning substitute for petroleum based diesel fuel. Biodiesel is made of vegetable oil.
To make or manufacture Biodiesel, you must first start with raw materials. The raw materials needed in the production of Biodiesel are a small amount of methanol and a ready supply of vegetable product.One of the most common vegetables used in the production of Biodiesel is corn, although depending on the geographic location of the manufacturing facility many other plants are used as well (rapeseed, soybeans, flaxseed, etc.). The first step is to use the raw vegetable product to make vegetable oil. Vegetable oil by itself will not be what you need to power a car, from here it has to be processed into Biodiesel.The process for converting vegetable oil into Biodiesel is sometimes called ester interchange. To complete this process the vegetable oil has to be combined with a smaller amount of methanol and then put in the presence of a small quantity of an alkaline catalyst (for example, 5% to 1% sodium hydroxide). Vegetable oil is made up of so-called triglycerides, which is a compound of the trivalent alcohol glycerin with three fatty acids.The goal of ester interchange is to separate the glycerin molecule from the three fatty acids and replace it with three methanol molecules. This process then yields roughly 90% Biodiesel and 10% of a glycerin byproduct. The glycerin byproduct can be used in a number of other chemical processes for different industries.
