Biogas was produced from caw, chicken and mixed manure. Samples were taken before and after biogas production and tested for removal of total solid (TS), removal of chemical oxygen demand (COD), biological oxygen demand (BOD), and fecal coliform bacteria (FC). Results showed tremendous removal of the above mentioned parameters after biogas production. Chemical analysis of digestate indicates the advantages of using them as plant nutrients. Application of digestate in soil dramatically changed the chemical and physical properties of soil. It can be concluded that biogas production, is not only producing biogas but also removing waste parameters (TS, COD, BOD, FC) and producing plant nutrients.展开更多
