Analysis of the sustainability of using wastes in the Brazilian power industry

This paper presents a methodology for analyzing the sustainability of using wastes in the Brazilian power industry. It will describe projects, both completed and under development by coordination of the post-graduation programs in engineering (COPPE) at the Federal University of Rio de Janeiro (UFRJ), for generating energy from wastes. The results of these projects were included in a doctoral thesis [Oliveira LB. Aproveitamento energetico de lixo e biodiesel no Brasil (energy use of garbage and biodiesel in Brazil). Dissertation (doctoral), COPPE/UFRJ, 2004, p. 204, http:// www.ppe.ufrj.br/ppe/production/tesis/lboliveira.pdf] defended in 2004 at the Energy Planning Program of the COPPE at the UFRJ-PPE/COPPE/UFRJ. The study encompasses an analysis of sustainability using a methodology developed for the above-mentioned dissertation, taking two existing methodologies into account: sustainability analysis and data envelopment analysis.
