Supermarkets are responsible for generating a considerable amount of solid waste. Several supermarket establishments suffer losses of products and the fruit and vegetables sector (FV) presents a high loss rate. In general, organic waste generated in the FV sector does not receive adequate treatment, which can cause problems for the environment and public health. Therefore, considering the problems that the incorrect disposal of those wastes can cause, as well as the environmental and economic benefits provided by composting, the present study aims to carry out the diagnosis of the organic residues generated in supermarkets of Presidente Prudente -SP and to investigate the feasibility of treating them through composting. The diagnosis will include the collection of information such as generation, segregation, storage, collection/transportation and final disposal of organic waste generated in the FV sector of the supermarkets analyzed. Subsequently, a study will be made to propose the composting of the organic residues of these establishments, in which the physical-operational structure necessary for the process will be surveyed. So, it's expected that the appropriate final disposal of organic waste from the FV sector of supermarkets will help to the environmental preservation, the recovering of materials and the revenue generation, from the proper management of the waste studied.
