Análise de viabilidade técnico-econômica de adoção de sistema de compostagem em condomínio residencial

Abstract

Urban development and the net consumption characteristic of the capitalist economic system, linked to the various changes in habits and production, mark an exhaustible exploitation of natural resources and promote one of the greatest challenges today, the management of solid waste and its adequate disposition. In order to reduce the amount of solid waste that is disposed of in landfills and dumps and minimize impacts on the environment, the development of sustainable practices, such as composting, take place in various scenarios. As investment and support to the sector of municipal solid waste collection and public cleaning remains low, making it impossible to take up municipal composting, the expansion of the practice in residential condominiums proves to be a solution. In this case, a technicaleconomic feasibility analysis of the adoption of a composting system in a residential condominium was carried out in a vertical condominium located in Londrina. In order to evaluate the economic viability of this case study, the indicators of Net Present Value, Internal Rate of Return, Payback and Cost-Benefit were used.
