Anaerobic co-digestion (AcoD) of animal waste and agro-industrial by-products has been widely studied employed to increase biogas production potential enhance process stability. This study evaluated the AcoD cattle manure (CM) brewer’s residual yeast (RY) in semi-continuous biodigesters, focusing on energy (biogas methane yields) Four treatments were assessed, each with different proportions (% volatile solids) CM RY: 100:0, 88:12, 78:22, 68:32. Trials conducted 30-L tubular reactors at room...
ABSTRACT: Anaerobic co-digestion (AcoD) of waste is a method increasing methane (CH4) yield and improving biofertilizer quality. This study aimed to evaluate the best AcoD conditions for swine manure (SM) with sweet potato (SP) or cassava (C) in different amounts semi-continuous biodigesters. Initially, using batch biodigesters, an test SM SP C was performed, adopting carbon/nitrogen (C/N) ratios 10/1, 13/1, 17/1, 22/1. Based on results, C/N ratio 10/1 chosen, which proportion that resulted...
Roof coverings are responsible for promoting a suitable environment animal production, in addition to be one of the main factors interfering with heat transfer. In this context, study aimed assess different roof covers over reduced-scale shed prototypes through thermography. The experimental design was completely randomized five treatments (TT, thermal; RT, recycled (Tetra Pak); ACT, asbestos-cement; BT, bamboo; and AT, aluminum tile) 14 repetitions, each assessment day. For roofing thermal...
A digestão anaeróbia (DA) é uma técnica notória na destinação dos dejetos do setor da bovinocultura, no entanto, buscam-se métodos de aprimoramento para esse processo. Dessa forma, objetivou-se avaliar o efeito aplicação direta biorremediador e amido comercial DA bovinos leiteiros (DBL) com a finalidade entender biorremediador. Foram, utilizados biodigestores tubulares semicontínuos volume útil 60L, tempo retenção hidráulica 30 dias, em temperatura ambiente. Foram avaliados quatro...
O dejeto de bovino leiteiro é amplamente empregado na digestão anaeróbia, no entanto, apresenta características que requerem mediação para alcançar melhor desempenho. Assim, objetivou-se avaliar a aplicação doses crescentes e uma superdose biorremediador anaeróbia dejetos bovinos leiteiros. Foi utilizado o delineamento inteiramente casualizado, com quatro tratamentos, correspondentes as quatros testadas (0; 0,5; 1,0 10 mL), conduzidos em temperatura ambiente, biodigestores bancada volume...
