AbstractThe waste originated in temples is presently piled up at one place and then disposed off in water bodies or dumped on land to decay, leading to water and soil pollution. The present work aims to determine the biogas yield and nutrient reduction potential of Ocimum sanctum (basil) leaf waste obtained from temples. Laboratory scale digesters of 2.5 L capacity were used and fed with basil leaf waste, which was digested in a batch reactor for a retention period of 30 days at room temperature. Preliminary results indicate that the process is effective in reducing the pollution potential of the basil waste. The process removed up to 73% and 42% of total solids and BOD, respectively, along with biogas production.
