Generating Renewable Energy from Municipal Waste Sector: A Comparative Study between Japan and Indonesia

Abstract

Although Indonesia has abundant resources to produce renewable energy (RE) from municipal solid waste (MSW), the implementation of waste to energy (WtE) concept remains low due to several factors. Approximately, 200,000 tons of MSW per day are generated in Indonesia. Improper waste management system in Indonesia is not only causing environmental problems but also inhibiting to get benefits from RE production. This study which was funded by Japan International Cooperation Agency (JICA) was conducted to obtain a comparative description of WtE implementation between Japan and Indonesia as well as to formulate possible strategies for improving WtE implementation in Indonesia. Direct observations and a series of qualitative depth interviews with stakeholders were conducted both in Japan and Indonesia. This study revealed that the two countries have a different approach of WtE implementation. The implementation of WtE in Japan mostly relies on thermal treatment as a form of intermediate treatment of MSW to reduce the amount of waste sent to landfill as well as to increase the life span of landfill. In Indonesia, WtE implementation mostly uses the biological treatment (anaerobic digestion) as a part of final treatment of MSW in landfill. Conducting integrated waste and energy management system is one of best practices from Japan that can be learned and applied in Indonesia to improve the implementation of WtE.Index Terms-Incineration, landfill gas, municipal solid waste, waste to energy.

Emisi Gas Rumah Kaca (Grk) Dari Pembakaran Terbuka Sampah Rumah Tangga Menggunakan Model Ipcc

“…Jumlah sampah permukiman di Indonesia mengalami peningkatan 2-3% per tahun sebagai akibat dari terjadinya peningkatan populasi dan pertumbuhan ekonomi (Wijayanti & Suryani, 2015;Wahyudi & Novitasari, 2018). Pertumbuhan ekonomi dan kemakmuran suatu negara juga mempengaruhi komposisi sampah permukiman.…”

“…Perbandingan Tingkat Insinerasi Sampah Beberapa Negara Sumber : Ikeda (2017); Bakas, et al (2017) awal (Albores, et al, 2016). Bahkan teknologi terbaru yang diterapkan pada insinerator di Jepang mampu mengurangi volume sampah hingga 97,5% (Wahyudi & Novitasari, 2018). Selain itu, panas yang dihasilkan dari pembakaran sampah di insinerator dapat dikonversi menjadi energi baik panas maupun listrik.…”

“…Insinerator dilengkapi dengan sistem pembersihan gas hasil pembakaran (flue gas cleaning system) sehingga emisi yang dihasilkan memenuhi persyaratan lingkungan. Keberadaan sistem pembersihan gas buang tersebut menyebabkan pembangunan dan pengoperasian insinerator membutuhkan biaya yang sangat besar sehingga negara berkembang dengan kemampuan finansial terbatas kesulitan untuk menerapkan teknologi tersebut (Wahyudi & Novitasari, 2018).…”

Garden Waste for Sustainable Development in Indonesia

“…The decentralized waste management system, which has been in place since 2004, primarily relies on landfill disposal, resulting in increased waste in landfills. Adopting more efficient management strategies is crucial to overcome this challenge [3].…”

Sustainability Challenges of The Landfill Gas Power Plants in Indonesia

“…One of the solutions to enhance sustainability is integrating landfill gas (LFG) power plants with the waste management system. The integration emits less GHG [9,10,11] and reduces the health risks of an open dumping system [12]. LFG from MSW could be utilized as an energy source due to its methane content [13].…”
