This flow constant reverse exists in almost all the market segments, where the return of merchandises to the origin (either for retrabalho, defect, imperfections, problems of substance cousin, packings) is frequent. The rapidity with that if they launch new products in the market, the high technology, the high competitiveness of the companies and the increase of the ecological awareness how much to the consequences generated for the irregular deposit of products and its residues, is contributing for the adoption of new behaviors, as much for the organizations how much for the society. This comes making possible a bigger valuation of the processes of return of products, materials and residues, to its origin or its adjusted destination, minimizing the ambient degradation. The consumer notices itself that more is worried about the environment, for the creation of more rigorous environmental laws, that the standards of services and the care of the companies with its coorporativa image have stimulated all the levels of the society and enterprise for the implantation of canals the reverses of distribution, reducing the problems generated for the excess of discardings in the nature. Another form of if observing the application and the necessity of the Logistic Reversa are the canal existing reverse to the end of the useful life of a product, already in ownership of the customer. In fact, the life of a product, under the logistic point of view, does not finish with its delivery the customer, that is, when the product becomes obsolete, damaged or spoiled, the same it must be discarded.
This discarding can be in points of fixes or reaproveitamento, or simply, with its destruction, in aterros. For one better understanding of Logistic Reversa, figure 1 shows, in flow form, its operation; Figure 1: Logistic process Reverse Source: Guarnieri (2006, P. 5) the Logistic Reversa is divided in two areas distinct of performance: 2.1.1 Logistic Reversa of good of after-I consume: It is the area of the Logistic Reversa that deals with products in the end of its useful life, that already they had been used and still they have possibility to be reused, such as, industrial plastics, cans, paper, residues, botijo of gas, water demijohn, vasilhame of drinks, amongst others (MILK, 2003) 2.1.2 Logistic Reversa of good of after-sales: It is the area of the Logistic Reversa that deals with the planning, has controlled and destination of the products without use or little used, that they return to the chain of distribution for diverse reasons, such as guarantee, you damage of transport, stated period of validity looser, obsolete, exceeded, it are of time, amongst others.
