Putting solid household waste to sustainable use: a case study in the city of Rio de Janeiro, Brazil.
The management of solid residues has, in recent decades, been a source of concern for public administrators the world over. Experiments in the sustainable use of such residues are highly relevant in social and environmental terms, stimulating widespread interest and debate, with considerable research going into sustainability projects. In many areas, however, adequate public funding for sustainable-use projects is hard to come by. One of the major reasons for this is that public authorities, particularly in times of financial constraints, are reluctant to invest in undertakings in which the economic returns are difficult to quantify. Official scrutiny of the expenditures of public authorities is also normally heavily influenced by cost-benefit analyses. The specific objective of this article is to show that putting solid domestic residue (household solid waste) to sustainable use is capable of generating economic returns, as well as environmental benefits for society as a whole. These economic returns can be set out in financial statements, which may, in turn, be used to justify expenditures by public authorities on sustainable-use projects and as a basis for further investment in such incentives. We drew on the findings of existing research into sustainable use, undertaken by the Municipal Urban Cleaning Company in the city of Rio de Janeiro, Brazil, to establish a conceptual framework for setting out the economic results of the collection of household solid waste.
