The escalating plastic pollution in the environment poses a significant threat to ecosystems and human health, necessitating innovative solutions for plastic waste management. This study explores the primary treatment of synthetic plastic waste materials through dissolution methods utilizing solvents like water, acids, alkalis, and other organic solvents like toluene, xylene, petroleum oil, etc., under controlled temperature and pressurized conditions. While this approach is economically challenging and presents certain limitations, it is critical in facilitating the biodegradation processes in subsequent treatment stages. The findings indicate that although treatment steps involving acids and alkalis offer specific benefits in recycling plastics, they also come with inherent drawbacks. In contrast, water serves as a universal solvent with no major limitations, effectively promoting the transition to biodegradation. This dual-functionality highlights the potential of dissolution methods to enhance recycling and biodegradation strategies, contributing to more sustainable plastic waste management practices in the background of persistent plastic pollution.
