Item Biotecnologia; em casa: obtenção de biogás e biofertilizante empregando esterco e resíduos de alimentos(Universidade do Estado do Amazonas, 2019-01-16) Santos, Menilson Azevedo dos; Santos, Raimundo Gracival de Almeida dos; Rodríguez, Arelis AbalosIn livestock production and processing and sale of food appreciable amounts of biodegradable waste to be deposited in the untreated waste contribute to the proliferation of vectors and diseases occur. These residues can be measured by anaerobic digestion to produce biogas and bio fertilizer. This paper aims to use waste food for cattle and produce biogas and biofertilizers in simple home digesters for use in small rural communities. The methodology consisted in designing a simple digester from recycled material. The biogas produced is used as fuel for cooking food and digested sludge fertilization chives. 5L two digesters were used, using the 70 % volume of the reactor with manure and foods. In 45 days of the experiment were obtained 30.23 L and 7.05 L of methane respectively. At 5 days germinated seeds in fertilized plots, reaching 32 cm in height at 45 days , being harvested for use in food preparation Key words: solid waste; biogás; anaerobic digestion; biofertilizer.
