Abstract
The world generates enormous amounts of municipal solid waste every day, leading to environmental pollution and the depletion of natural resources. Converting waste into an energy source is a promising solution to address this issue. This study explores the use of waste, specifically plastic and paper waste, as part of the feedstock mixture in a gasification unit for synthesis gas (syngas) production and presents an economic analysis of the use of an internal combustion engine associated with a generator for electricity supply. Based on experimental data, a technical analysis is performed for the use of the produced syngas in a dual-fuel blend with biodiesel, which was also obtained in laboratory from the process of transesterification of waste cooking oil. Thermodynamics calculations are performed for calculating the power delivered by the engine, the heat flux of energy gases and the electricity efficiency, among other parameters. The syngas used presented about 9% of hydrogen in its composition, and the electricity efficiency was of about 18% in the experiment with the syngas-biodiesel as fuel. The economic analysis considered cost of investment, cost of operation and cost of maintenance, also, three levels of interest rates were applied for a sensibility analysis. It is observed that for interest rates of 4% and low fuel production costs, the payback period of the plant is achieved in around 3 years considering residential electricity tariffs applied nowadays.
