Experimental study on solid waste management in slaughter house

Abstract

To minimize the solid waste disposal and to enhance the eco system. The main aim of this research collects Solid waste from the slaughterhouse. It was kept for five days during the period of incubation solid waste material turn into liquid waste. The biogas plant was fabricated and installed. The fresh cow dung about 150 kg was procured and made into slurry and incubated for three days. The cow dung was charged into biogas plant for generation of biogas. The liquid medium of slaughterhouse was partially charged and again the generation of biogas was determined. Once it is confirmed further charging of the liquid waste of slaughterhouse was continued. The biogas plant which has gas holder was found to rise fully indicating the biogas production in the plant. This was once again tested for conformation for product of biogas. The biogas plant which has 750-liter capacity gas holder is known to contain about 700 L of biogas out of this 700-litre capacity the burning time of biogas was found to be two hours duration. This was confirmed by taking the biogas in the special lorry tube for studies. It is found that the biogas of about 0.4 kg f biogas production per day has been recorded. The biogas from the slaughterhouse was analysed for its composition. The sludge generated from the biogas plant was collected separately and passed through sand filter and the filtered sludge was solar dried and made into cake and it was used as manure. The wastewater generated from the biogas plant was also collected and passed into the sand filter and carbon filter. The filtrate was used as the nutrient medium for the kitchen garden.
