There is a growing amount of plastic waste that needs to be properly disposed of in order to protect the environment from the negative effects of increasing reliance on plastic products. Recent interest has focused on chemical recycling as a means of reducing plastic's negative environmental effects. Converting waste plastics into basic petrochemicals allows them to serve as hydrocarbon feedstock or fuel oil through pyrolysis operations. Scientists have taken a keen interest in the production of bioethanol from renewable feedstocks due to its potential as a source of energy and alternative fuel. Due to its beneficial effects on the environment, ethanol has emerged as a promising biofuel. In this paper, energy recovered from low-density polyethylene and high-density polyethylene waste was converted into an alternative plastic fuel and evaluated for its environmental impact with the blending of ethanol in a diesel engine. Ternary fuel blends with 20%, 30%, and 40% waste plastic fuel and 10%, 15%, and 20% ethanol with standard diesel were tested. The study found that blending 10% ethanol with 20% plastic fuel decreased fuel consumption by around 7.9% compared to base diesel. Carbon monoxide emissions are reduced by about 10.2%, and hydrocarbon emissions are reduced by about 13.43% when using the same ternary blend. The optimum values of fuel consumption and emissions were obtained by full factorial design for a ternary fuel blend of 10% ethanol and 20% plastic fuel at the full load condition.

“…The combination of two oxygenated additives with waste plastic fuel was not carried out in diesel engines. The blend ratio of additives was adopted between 5 and 15% with WPF in many of the investigations 15 , 16 , 19 , 20 , 22 , 23 . Hence, the addition of additives is preserved at 10% on a volume basis, which is considered the optimum ratio.…”

“…Ravi and Karthikeyan 15 suggested that propanol blend with plastic oil was preferable in terms of performance and emission compared to diesel, and in that emissions, norms are reduced. Das et al 16 have examined WPO and ethanol for improved performance and lower emissions, and the Taguchi method has been used to optimize the performance and emissions. According to the findings of this research, greater compression ratios and higher loads result in the greatest possible BTE and the lowest possible emissions for 20% ethanol and 20% WPO mixed diesel.…”

The widespread use of plastic goods creates huge disposal issues and environmental concerns. Increasing emphasis has been paid to the notion of a circular economy, which might have a significant impact on the demand for plastic raw materials. Post-consumer plastics recycling is a major focus of the nation’s circular economy. This study focuses on energy recovery from waste plastics as an alternative fuel source to meet the circular economy demand. Waste plastic fuel produced through pyrolysis has been claimed to be utilized as a substituted fuel. This work focuses to determine the performance and emission standards of Waste Plastic Fuel (WPF) generated from the pyrolysis of High-Density Polyethylene (HDPE) in a single-cylinder Direct Injection Diesel Engine (DIDE). Three different ratios of WPF were combined with 10% ethanol and 10% ethoxy ethyl acetate as an oxygenated additive to create quaternary fuel blends. The ethanol has a low viscosity, a high oxygen content, a high hydrogen-to-carbon ratio as favourable properties, the quaternary fuel results the improved brake thermal efficiency, fuel consumption and reduced emissions. The blend WEE20 exhibits 4.7% higher brake thermal efficiency, and 7.8% reduced fuel consumption compared to the diesel. The quaternary fuel blends demonstrated decreased carbon monoxide of 3.7 to 13.4% and reduced hydrocarbons of 2 to 16% under different load conditions.

“…There is a positive correlation between load, compression ratio, waste plastic oil, and ethanol in diesel, all of which contribute to greater thermal efficiency and fewer harmful emissions. ANOVA and multivariate analysis found the sweet spot for engine load, compression ratio, and fuel blend, which improved performance and reduced emissions (Das et al 2020). The thermal efficiency of braking and emissions were improved by using a compression ratio of 18.1, along with a blend of diesel fuel containing 20% WPO and 20% ethanol.…”

The rapid increase in energy demand brought on by the global population boom has led to a surge in the popularity of recycling waste materials into usable energy sources. That is to say, turning trash into usable energy will soon be a hot topic. More and more people are becoming aware of the benefits of biodiesel as a way to lessen their environmental impact by replacing their regular diesel fuel with a cleaner alternative. Usually, biodiesel is produced by mixing vegetable oils with animal-based oils. Because of its low production cost and low environmental impact, waste cooking oil (WCO) is suitable for biodiesel research. Using oxygenated fuels appears to be a practical strategy for lowering engine pollution. The purpose of this study is to examine the effects of varying amounts of diethyl ether (DEE) additives and waste cooking oil biodiesel on the efficiency and emissions of a diesel engine. Emission parameters were evaluated in comparison to those of pure diesel, and results were optimized for various load conditions and mixtures of oxygenated additives.
