Resumo: In this study, we compared cassava starch-based biodegradable polymers (PBMs) and glycerol (G) as additives used to increase biogas production from the co-digestion of swine wastewater (ARS). We chose to work with an inoculum comprising 40% (v/v) of the total volume of the reactor; this inoculum was obtained from a Canadian model digester for treating swine waste. In the anaerobic digestion process, batch reactors were used on a laboratory scale with a total volume of approximately 4 L and a working volume of 3.2 L. Three treatments were conducted to compare the efficiency of solid removal, the chemical oxygen demand (COD), and the production of biogas. The first treatment contained only swine waste; the second included the addition of glycerol at 1, 3, and 5% (w/v); and the third treatment included the addition of 1, 3, and 5% (w/v) of PBM residue in relation to the swine wastewater. From the results, it can be concluded that higher yields were obtained for the treatment with 3% PBM and 1% glycerol. Most treatments showed high removal rates of total solids and total volatile solids. Reductions lower than 70% were obtained only for treatments with PBM and glycerol at a ratio of 5%.

Utilizou-se como matéria-prima para produção de biogás, água residual de suinocultura, material plástico biodegradável produzido a partir de fécula de mandioca e glicerina bruta proveniente do processo de produção de biodiesel. Optou-se por trabalhar com 40% (v/v) de inóculo do volume total do reator. Para a condução do processo de digestão anaeróbia empregaram-se reatores com alimentação batelada de escala laboratorial de volume total de aproximadamente 4 litros e volume útil de 3,2 litros. Foram realizados 3 tratamentos visando comparar a eficiência da remoção de sólidos, demanda química de oxigênio e produção de biogás. O primeiro tratamento conteve apenas resíduo de suíno, o segundo a adição de glicerol em percentuais de 1, 3 e 5% (m/v) no mesmo resíduo e o terceiro a adição de 1, 3 e 5% (m/v) do polímero biodegradável a base de fécula de mandioca ao resíduo suíno. A partir dos resultados pode-se concluir que as maiores produções foram obtidas no tratamento de 3% de PBM e 1% de glicerol. A maioria dos tratamentos apresentou elevadas taxas de remoção de sólidos totais e sólidos totais voláteis. Apenas os tratamentos com PBM e glicerol na proporção de 5% obtiveram reduções inferiores a 70%.UEL2016-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2209010.5433/1679-0359.2016v37n4p1827Semina: Ciências Agrárias; Vol. 37 No. 4 (2016); 1827-1844Semina: Ciências Agrárias; v. 37 n. 4 (2016); 1827-18441679-03591676-546Xreponame:Semina.
