STELLA staff assessed whether the US Trade and Development Agency (USTDA) should provide funding for the Rio de Janeiro Sludge Treatment Feasibility Study and the Suape Industrial Port Complex in Brazil. The Rio de Janeiro Water and Sewage Company (CEDAE) is a state-run company in charge of water supply and wastewater treatment within the State of Rio de Janeiro. CEDAE must find a way to handle the sludge resulting from wastewater treatment and is interested in giving a concession to a private firm for sludge treatment. STELLA staff recommended that USTDA fund $300,000 for a Rio Sludge Management Feasibility Study, subject to CEDAE's agreement that any sludge management projects will be developed and operated as concessions. The Suape Industrial Port Complex is in a large industrial area in the south of Recife in the State of Pernambuco. According to the feasibility study conducted by the Federal University of Pernambuco, at least two dozens of industrial units of the industrial complex generate 23 tonnes of hazardous waste per day, about 7,000 tonnes per year. Suape would like an external company to manage its hazardous waste, as is currently the case for electricity, water, and other services. The company selected to manage hazardous waste could also manage solid waste generated by the city of Recife. STELLA staff recommended that USTDA fund $25,000 for a pre-feasibility study to obtain agreements from various multinational companies ready to hire this company to manage their hazardous waste.
