| dc.description.abstract | Tons of organic waste such as swine manure are being generated and represents a major contributing factor to eutrophication and pollution of water bosied in the country. To reduce the risk of pollution and greenhouse gas emissions, swine manure can be used to produce biogas, a renewable source of energy using biogas-digester waste management strategy that generates and capture methane gas. Results shwed that T1 (sludge+CRH) obtained the highest NPK content of 3.25% followed by T4 (sludge+DL+RS+CRH) with 2.31% then T3 (sludge+RS+CRH) with 2.13% and T2 (sludge+DL+CRH) with the lowest NPK content of 1.88%. Temperature, odor, pH and percent recovery were also determined and evaluated in each treatment. Therefore, In this study, the biogas digester spent sludge from a swine farm when combined with different substrates resulted to production of soil conditioner. | |
