Abstract
The rapid growth of plastic manufacturing has supported industrial development, but simultaneously intensified post-consumer plastic waste generation, raising serious environmental concerns. Pyrolysis, a thermal decomposition process in an oxygen-free environment, offers a promising pathway to convert plastic waste into diesel-like fuel. This study investigates commercial B10 (10% palm methyl ester) and two plastic-derived blends: HDPE10 (10% high-density polyethylene) and PP10 (10% polypropylene), and B0 (pure diesel) as guideline tested on a Yanmar L48N6-MTMRYI diesel engine following ISO 8178 D2. The objective is to characterize fuel properties, investigate the performance and emissions trend, and predict nitrogen oxides (NOx) emissions using machine learning (ML) techniques.
