Although Law No. 18 year of 2018 has mandated recycling to be prioritized in solid waste management, the municipality intend to collect and to dump the waste directly to landfill. By cooperating with National Gas Company (PT. PGN), bioplant was constructed at area of 200 m 2 and operated at Jatinangor Campus of Institut Teknologi Bandung to treat organic waste generated from the campus and traditional market near the campus. The study aims to evaluate the performance of the bioplant in term of biogas generation and composition during the pilot project. Main treatment at the bioplant is anaerobic digestion (AD) using two units with single-stage and wet fermentation. Organic waste as feeding had 62%, 61% of water and volatile contents, respectively. Carbon organic and total Nitrogen contributed 8.19% and 0.22%, respectively. 200 kg of the organic waste daily was mixed with ratio of 1:1 with water. Total volume biogas generated daily from 2 units of AD was 2.1 m 3 with composition of 45%, 15%, and 10% of CH 4 , CO 2 and O 2 , respectively. Due to the waste reduction at source, various potential negative impacts due to open dumping commonly operated at landfill site in Indonesia could be avoided.
