Abstract

Plastic waste originating from fishing gear, composed of both polyethylene (PE) and polyamide (PA) materials, constitutes a pressing environmental concern. Addressing this issue, pyrolysis emerges as a transformative avenue, converting plastic waste into liquid fuel that can serve as an alternative energy resource. This research ventures into a comprehensive investigation of the physical properties intrinsic to plastic oil, encompassing pivotal attributes such as viscosity, density, cetane number, and calorific value. By delving into these properties, the study aims to shed light on the potential of plastic oil as a viable energy source and to understand its applicability within the realm of sustainable fuel alternatives. However, this study^s scope extends beyond the elucidation of physicochemical intricacies. Beyond characterizing plastic oil, the research embarks on a holistic exploration encompassing engine performance when employing plastic oil in synergy with a 10% plastic oil and 90% biodiesel blend. This synthesis of fuel types becomes a pivotal aspect of the study^s inquisition, culminating in the assessment of engine torque, power output, and Specific Fuel Consumption (SFC). The outcome of these engine tests unveils intriguing insights-peak torque emerged with a 10% PE plastic oil blend, registering at 18 NW, while the highest power output occurred with PE plastic oil, reaching 3.9 kW. Moreover, the dynamic interplay between plastic oil blends and engine efficiency is highlighted, as evidenced by the highest SFC value obtained with a 10% PA plastic oil blend, measuring 12.298 g/Kw.min. The ramifications of this study reverberate far beyond the confines of the laboratory, resonating with the dire need for sustainable energy solutions. By decoding the complex matrix of plastic oil properties and evaluating their seamless integration into combustion processes, this research contributes to the evolving narrative of sustainable energy utilization. As we grapple with the ramifications of plastic waste, this study offers a nuanced perspective that transcends mere material reclamation, propelling us towards an energy landscape that bridges ecological responsibility and pragmatic resource optimization.
