Abstract
Continuous growth of human population and industrialization has resulted in increased energy demands. It is very much essential for a country like India, where 82% of crude petroleum is imported, to reduce dependency on imported fossil fuel. Besides this, lack of plastic waste management has resulted in a number of environmental problems. Plastic waste shares 9–12% of the total municipal solid waste (MSW) and nearly 30% of it hovers on sea’s surface. Therefore, an approach to convert fuel from waste plastic is proposed to significantly reduce landfilling of single-use plastics and meet energy requirements. The fuel, known as plastic biodiesel, was extracted from plastic waste after chemical treatment and pyrolysis process. Blends of 5–20% of biodiesel with natural diesel were prepared. These blends were tested on a four-stroke direct injection diesel engine of Mahindra Supro. The engine was run at different brake power, and performance and emission characteristics were observed. The CO2 emission was reduced to 6% as compared to diesel. To reduce NOx emission, 10–15% exhaust gas was recirculated in engine. The CO emission remained constant at all engine load throughout the experimentation.
