Abstract

Lampung is the biggest contributor for cassava production in Indonesia. Recently, Lampung produced 7.57 million ton of cassava tubers annually and contributed about 34.4% of the national cassava production. Therefore, Lampung is the home for cassava-based industries. There were 76 industries are in operation in Lampung, including four small scale tapioca industries called ITTARA. These industries wasted huge of water having potential to generate biogas through anaerobic digestion process. The objective of this paper was to study greenhouse gas (GHG) emission mitigation of cassava mills in Lampung by using biogas fuel resulted from wastewater treatment. The study evaluated GHG emission from the existing conditions and then calculate GHG emission reduction potential in the processing step by utilization of waste. General life cycle methodology was applied for the evaluation of GHG reduction. Results showed that 2.82 to 4.5 m3 of waste water were produced for every ton of cassava being processed. The waste water was characterized by high organic matter with an average COD of 18,000 mg/L. During waste water treatment, biogas was estimated at around 26 m3 per ton cassava with methane content of 56.2 vol.%. The study also revealed that utilization of biogas may replace a part of diesel fuel used in the cassava mills and therefore potentially reduces GHG emission. Assuming that 80% of cassava production was processed directly in cassava mill, it can be showed that total biogas energy potential throughout Lampung Province was equivalent to 87.4 million liters diesel fuel per year. This quantity will reduce GHG emission about 1.32 million tons of CO2 equivalent per year. Keywords: Biogas, Greenhouse gas, Emission, Cassava mill, Mitigation.
