Optimization of a proposed biomass generator: Harnessing citizen waste with electric vehicle charging infrastructure

• A grid-tied biomass power plant is investigated. • The proposed biomass generator utilized the citizen waste with EV charging station. • A 40.69 kW electric vehicle charging station is powered by biogas. • A detailed technical, economic, and environmental assessment is performed. • The proposed optimized system offers a cost-effective energy solution. • Simulation results show a favorable cost of energy of $0.03/kWh. • The new system aims to enhance environmental protection and establish new energy sources. Global municipal solid waste production is rising, causing significant environmental, health, and economic issues. Developed countries have advanced recycling technologies, but cities like Dhaka, Bangladesh—among the most densely populated-struggle with inadequate waste management. This feasibility study aims to improve environmental protection and create new energy sources by proposing a waste management system across Dhaka, focusing on waste valorization for bioenergy with optimized efficiency and minimal impact. The study includes design and optimization of a biomass-based power plant to meet the energy needs of EV charging stations and the national grid, evaluating its economic performance through discounted cash flow and payback period analyses. The paper explores the integration of an EV charging station powered by biogas, addressing the growing need for EV infrastructure in Dhaka. By evaluating biomass generators as a greener alternative to fossil fuels, the study analyzes the technical, economic, and environmental feasibility, including CO2 emissions, using HOMER Pro.
