This type of income already exists has many years, is only few the countries adopt that it. The paper is one of the main products of the recycling, goes to understand its importance. The amount of paper that a person of a developed country plays outside per year is equivalent to the amount produced for two knocked down trees. Each ton of recycled paper means that about twenty trees they leave of being knocked down and the process of recycling of the paper spends little energy of what the production of paper with the cellulose of the trees. In each recycling the paper loses cellulose, that it needs to be restituted in certain amount, but exactly thus, the process also saves trees and energy. In the same way when recycle the glass and the aluminum, we diminish the ore consumption and also we will save energy. The recycled glass production saves 75% of energy in relation to the production of the not-recycled glass, while the metal production recycled it saves 85% of energy.
The necessity and the importance of the recycling of the garbage happen essentially of a set of factors, whose basic space dimension contitui condicionante: the exhaustion of raw materials, cost increasing of raw material attainment, economy of energy, non-availability and increasing cost of the sanitary aterros, cost of increasing transports, pollution and damages the public health, generation of income and job and reduction of the production costs. (CALDERONI, 1999, P. 35-38) It is very easy to recycle the organic garbage, transforming it into seasoning. In the compostagem plants (that they recycle garbage), the organic part of the garbage – vegetable and food remaining portions as leves, fruits, rinds of fruits, bagasses and deteriorated vegetables? initially it is placed to leaven. After this procedure, the composition (that it is the product of the fermentation) for a special machine is taken, transforms that it into seasoning.
