The Waste-to-Energy (WtE) Technology to Support Alternative Fuels for Agriculture in the Context of Effective Solid Waste Management in the Jabodetabek Area, Indonesia

Jabodetabek has been termed Indonesia's most populous urban area, and it is predicted to generate around 9.069 million tons/year by 2023. On the other hand, this area has promising agricultural prospects and requires a great deal of energy. Tractors, generators, and other agricultural equipment are necessary to increase productivity. Therefore, it can potentially convert waste into energy as an effective alternative fuel for agriculture. This study looked at ways to recover the waste to energy (WtE) with various technologies (incineration, gasification, pyrolysis, landfilling, and anaerobic digestion). The assessment indicators focus on the type of waste, energy production efficiency, energy produced, technological readiness, capacity, byproducts, costs, air pollution, water pollution, and soil pollution. Each WtE technology is assessed using a scale between 1 (worst) and 5 (best) on each performance indicator concerning related references. Based on the analysis, the anaerobic digester is the most attractive WtE technology to generate an alternative fuel for agriculture in the Jabodetabek area. This is an environmentally friendly and economical technology because the technology readiness level is relatively mature. Thus, this review will assist policymakers and implementing authorities in determining the potential of the right WtE technologies for effective alternative fuel generation for agriculture, particularly in the metropolitan region of Jabodetabek.
