Urban Waste Management Solution through SRF Cofiring in Coal-Fired Power Plants

Abstract

Abstract Solid Recovery Fuel (SRF) is a highly effective waste product processed through sorting and separation from non-combustible materials in Indonesia. The SRF is then dried to increase its calorific value and ensure homogeneity. Most Indonesian SRF is derived from urban waste, which is predominantly organic material, making it comparable to biomass and having a calorific value akin to lignite coal. The state-owned electricity company, PLN, collaborates with local governments responsible for waste management to utilize SRF as a fuel source in coal-fired power plants through cofiring. This renewable energy mix is an optimal solution, eliminating the need to construct new power plants and optimize waste management programs and local government budgets without burdening PLN’s operational costs when managed through an appropriate collaborative scheme. PT PLN Indonesia Power has successfully conducted research and development efforts to transform urban waste into SRF through the Waste Treatment Facility program. They have also utilized SRF cofiring in coal-fired power plants up to the heat rate testing stage. This alternative solution benefits all stakeholders in addressing the waste management challenge. This program presents an opportunity to optimize waste management costs implemented by local governments, ultimately saving electricity generation costs. Moreover, it may help reduce the financial burden of constructing and operating conventional solar power plants. SRF cofiring in coal-fired power plants is a reliable and cost-effective renewable energy solution. The successful pilot project showcased the positive outcomes achievable through a collaborative management scheme that utilizes SRF products and environmentally friendly electricity generation for sustainable waste management. This approach effectively reduces greenhouse gas emissions and enhances renewable energy generation capacity, highlighting the significant impact possible through this method.
