Performance evaluation and conservation of waste solid plastics into alternative fuel for a pollution‐free environment

Abstract

The handling of waste plastics is a big challenge and various recycling routes are imposed to prevent the environmental ecosystem. Waste plastics are one of the major pollutants in the living environment and have characteristics such as non‐dehydration and toxicity. The wastages are occupying natural lands and water source areas, decreasing the soil behavior, reducing the minerals, and affecting the environmental ecosystem. In this situation, waste plastics are effectively handled with a suitable recycling process that helps to minimize toxicity. According to the present research, waste plastics are handled by separate arrangements and treated with the pyrolysis technique to obtain useful alternative fuel oil for automotive fuel applications. The synthesized pyrolysis (waste plastic oil fuel) oil fuel is tested by single stage four‐stroke diesel engines and its performance is compared with standard diesel fuel. The test results show that the brake thermal efficiency is improved by 28.85%. A higher 37% yield was obtained during this decomposition process above the 550°C temperature of 1 kg of waste plastics, formed as gas and condensed via cooling water, maintaining an ambient temperature. Moreover, the DI gas emission analyzer is used to evaluate the exhaust gas emission result found less than 1% of the CO and HC formation.
