Environment Secretariat of the State of São Paulo/Environmental Sanitation Technology Company (Cetesb)

Under this partnership, two agreements were signed in 2001 between MCT and the Environment Secretariat of the State of São Paulo/Cetesb for the development of the projects “Inputs to the recovery and energy use of biogas generated in anaerobic waste water treatment stations” and “Inputs to the recovery and energy use of biogas generated in solid waste disposal sites (SWDS)”, which include: i) producing a guide for the use of methane generated from liquid wastes in Brazil, fomenting the creation of centers aimed at supporting such an activity in the rest of the country. The main objective is to be achieved by means of the following secondary objectives: a) review feasibility assessment methodologies for biogas recovery and energy use; b) define a sample of anaerobic waste water treatment stations in Brazil; c) identify suppliers of equipment and services for biogas recovery and use; d) identify sources of financing; e) visit the selected anaerobic waste water treatment stations and assess the current conditions of biogas recovery in such stations; f) characterize energy demand in the surroundings of such stations; g) estimate the potential for biogas recovery at the selected stations; h) disseminate the results of the study, fomenting the creation of research centers in the rest of the country; ii) producing a guide for the use of methane generated from solid wastes in Brazil, fomenting the creation of centers aimed at supporting such an activity in the rest of the country. The main objective is to be achieved by means of the following secondary objectives: a) review the methodologies for a feasibility assessment of the recovery and energy use of biogas; b) define a sample composed of SWDS in Brazil; c) identify suppliers of equipment and services for biogas recovery and use; d) identify sources of financing; e) visit and assess the current conditions for the installation of energy recovery systems from biogas generated in the selected SWDS; f) characterize the energy demand in the surroundings of such SDWS; g) estimate the potential for biogas recovery in the selected SWDS; h) disseminate the results, fomenting the creation of study centers in the rest of the country. The budget for these projects was set at R$ 674,000 (six hundred and seventy-four thousand reals), of which R$ 300,000 (three hundred thousand reals) are to be provided by MCT/Climate Change Program and the remaining value of R$ 374,000 (three hundred and seventy-four thousand reals) by the partner institutions. A timeframe of 4 (four) years was established for the preparation of these studies.
