Abstract
The objective of this research is to evaluate methane emission reduction in palm oil mill through composting of empty fruit bunch. Experiment was conducted at a palm oil mill in Pangkalan Bun, Central Kalimantan, Indonesia. The composting period for the existing process was 30 days. In this experiment we also arranged 92.975 ton empty fruit bunch in two piles for composting period of 80 days. Each pile was sprayed with palm oil mill effluent for about one hour every another day and was turned over mechanically in between to facilitate aeration. This spraying and turning was terminated a week and two weeks before harvesting, respectively for 30-day and 80-day composting periods. Compost quality, palm oil mill effluent consumption, and methane emission were compared for both composting periods. Result showed that compost yield of 74.4% was achieved from 30-day composting period with 2.38 m3 of palm oil mill effluent consumption for every ton of empty fruit bunch. The numbers increased to 93.6% and 4.30 m3 for 80-day composting period. Total methane emission reduction is 35.92% and 53.22% for 30-day and 80-day composting period, respectively, as compared to that of mill without co-composting process.
