Reduce GHGs by Utilizing Biogas in Starch Industry

This paper includes findings from biogas as a renewable energy source and an important component in sustainable research and climate change mitigation efforts. It is created by the anaerobic digestion of organic materials in agricultural effluent. The method involves microorganisms breaking down organic material in the absence of oxygen, creating biogas. Biogas is largely composed of methane (CH₄) and carbon dioxide (CO₂), with trace amounts of nitrogen, hydrogen sulfide, and trace elements. Mitigation action attempts to reduce greenhouse gas emissions caused by methane gas delivered during the decaying of organic materials in starch wastewater. We can limit the release of methane into the atmosphere by capturing and utilizing biogas, thereby reducing greenhouse gas emissions and mitigating climate change. The purpose of this article is to fully utilize the potential of biogas as a component of sustainable research and climate change mitigation, especially in Indonesia’s cassava and Metroxylon starch industries. Investing in a covered lagoon anaerobic gas collecting system and a 1.5 MW modular electricity generation facility, with a total power generation of 0.9 MW per day, then lowering greenhouse gas emissions based on Tier 1 IPCC around 15.100 tCO₂^e per year.
