Recycling is the reprocessing of used materials that would otherwise become waste in order to break them down and remake them into new products. This is in contrast with reuse: collecting waste such as food containers to be cleaned, refilled and resold. Recycling prevents the waste being sent to a landfill or incinerator, reduces the consumption of new raw materials, and is advocated by supporters to require less energy than virgin production. Commonly recycled materials include glass, paper, aluminium, asphalt, steel, textiles and plastic. These materials can be derived either from pre-consumer waste (materials used in manufacturing) or post-consumer waste (materials discarded by the consumer). Recycling is a key concept of modern waste management and is the third component of the waste hierarchy. Recycling of waste requires a system of waste sorting, either by the producer or at a materials recovery facility.
One of the main benefits of recycling comes from reducing the amount of new material required. In theory, recycling allows a material to be continually reused for the same purpose, and in many cases this theory holds true, most notably in the recycling of metals and glass.
Since less raw material is required, recycling creates further benefits for materials where cost of the initial extraction or production is high—either economically, socially or environmentally. The recycling of aluminium, for example, saves 95% of the CO2 emmissions—an environmentally harmful greenhouse gas—compared to refining new metal.

Recycling is basically reusing a material and following are the purposes:
1. Consumers have the advantage of getting the products at a cheaper price. A product can be expensive because the raw material is not commonly found. So imagine a scenario where the trees gets depleted and consumers will have to spend more on buying newspapers or notebooks.
2. Recycling can result in better products. For instance, the tin used in cans is more refined after being processed for recycling.
3. There are cost-cutting benefits for companies. For instance, you are using 10% less energy if you are producing an aluminium brick from a recycled aluminium rather than from the raw material.
4. Consumers in one way or the other suffer from health hazards if plastic is not reused. Plastic is not degradable and can affect the seas and oceans from where water is sourced.
5. Companies need not invest heavily in mining if they can re-process mineral products.
6. Due to adverse environmental effects, consumers if given a choice will certainly buy a product that does not harm the environment. Companies can leverage their market strength by designing and advertising products that do less harm to the environment. For example, if you produce steel from recycled steel it means 86% less air pollution.

As simple as I can make it...
Swill can be used for animal feed.
Vegetable peelings can be placed in a composte pile for fertilizer
Plastics are reused to make "fleece" (one example)
Bottles, cardboard and paper collected and reused for same.
Cooking oil, if strained, can used again (french fries)..
It is being clever with waste products to "save the earth"
The cost of manufacturing does not change but cuts down on materials..
