15. Sanitation and Drying of Sewage Sludge on Radiant Floors Using Solar Energy and Biogas: Comparison between Different Thicknesses of Deposited Mass
ABSTRACT Sewage sludge is a solid waste composed of water, rich in organic matter and nutrients, but concentrator of pathogenic microorganisms. Its use as agricultural fertilizer in the state of Paraná, Brazil is common. However, it is necessary to eliminate or significantly reduce microorganisms by means of a hygiene process. This can be obtained thermally

16. AVALIAÇÃO DA PRODUÇÃO DE HIDROGÊNIO A PARTIR DA CODIGESTÃO ANAERÓBIA DE RESÍDUOS SÓLIDOS ORGÂNICOS E GLICEROL RESIDUAL DA PRODUÇÃO DE BIODIESEL
The anaerobic co-digestion of solid organic waste with residual glycerol from biodiesel production (1% v v-1) for hydrogen production was investigated by means of the Biochemical Hydrogen Potential (BHP). The specific hydrogen production from co-digestion with and without glycerol corresponded to 140 mL H2 g VS-1 and 87,3 mL H2 g VS-1 removed, respectively,

17. APPLICATION OF THERMAL PLASMA FOR INERTIZATION OF SLUDGE PRODUCED DURING TREATMENT OF LANDFILL LEACHATE
One of the outstanding issues of concern by governments and society in general relates to the final destination of solid waste, which can bring severe impacts on social, political, economic and environmental dimensions. The sustainable development of enterprises and industries goes for the care of the planet, thus ensuring the quality of life for future gene

18. Methane production in anaerobic digestion of organic waste from Recife (Brazil) landfill: evaluation in refuse of diferent ages
This work focuses on monitoring the generation of biogas by biochemical methane potential (BMP) assays, commonly used to assess anaerobic biodegradability of solid and liquid wastes under controlled conditions. The experiment employed 5 g of substrate of both refuses (fresh and one-year-old wastes), digested with 250 mL of inoculum in 1 L flasks as bioreacto

19. Subsídios para implantação do processo de compostagem em município de pequeno porte : estudo de caso em Corumbataí-SP / Subsidies for the implementation of the composting process in a small municipality. Case study: Corumbataí-SP
University of São Carlos, 2012. Composting is one of the oldest processes of recycling organic waste. Despite being an environmentally appropriate treatment, their use is still little known regarding the management of municipal solid waste (MSW). This study aimed to investigate the management of MSW in Corumbataí - SP. For this purpose gravimetric characte

20. Application of enzymes in leather processing: a comparison between chemical and coenzymatic processes
The use of biotechnology by tanneries has increased in recent years. Enzymes can be applied during different steps of the leather production process: soaking, dehairing, bating, dyeing, degreasing or in effluent and solid waste treatment. This study evaluated the performance of five commercial enzymes in soaking and unhairing/liming by comparing the chemical

21. Extração sequencial de zinco e cobre em solos tratados com lodo de esgoto e composto de lixo
This work aimed to access the contents and chemical forms and to estimate mobility and availability of cooper and zinc in samples from two soils (Haplortox and Paleudult) previously treated with doses of sewage sludge (SS) and municipal solid waste compost (MSWC), besides a control treatment. Largest percentages of Cu and Zn were determined in the organic ma

22. Disposição de lodo adensado de ETA em ETE com tratamento primário quimicamente assistido / Thickened water treatment sludge disposal in a wastewater treatment presenting a chemically enhanced primary treatment
Treatment systems, even for water potabilization or to reduce the amount of pollutants in wastewater, include physical, chemical and biological processes, and waste generation are inherent to water or sewage treatment plants. Solid waste generated in water treatment plants have inorganic characteristic, being removed from raw water by chemical and physical p

23. Produção de biogás a partir de glicerol oriundo de biodiesel / Biogas production from glycerol generated on biodiesel industry
The Brazilian legislation demands the use of biodiesel mixed with diesel in an increasing rate. This raise on biodiesel production implies also on an increase on generation of glycerol, which is a liquid or semi-solid waste with high concentration of salts (approximately 46.1 g\ CL POT.-\ /L) and organic matter (1260 gCOD/L in average). Despite being widely

24. Evaluation of bioavailability of heavy metals in urban waste in solid for extractors in Brazil
The organic fraction of urban solid waste (USW) is around 60% of the total. The composting is a simple and efficient process to recycle this fraction of the USW, transforming it in organic fertilizer. The compounds of waste can contain a value assigned to aggregate economic potential of reuse of micronutrients (Cu, Ni and Zn) contained therein, in the produc
