Life Cycle Assessment (LCA) and Environmental Impacts Towards Plastic Waste by Using Pyrolysis
AI summary Read the abstract
This study used life cycle assessment to evaluate the environmental impact of converting plastic waste into fuel through pyrolysis. The findings suggest pyrolysis can reduce plastic waste in landfills while generating usable energy, though careful emission management is required.
Plastic waste pollution is a developing global issue that must be addressed immediately. Despite increased recycling rates, most plastic still ends up in landfills, contaminating the environment and destroying ecosystems. Pyrolysis technology offers a potential solution to this issue by dissolving plastic trash into its component parts and producing electricity without releasing harmful pollutants into the atmosphere. Since it can be used without emitting toxic gases into the atmosphere, pyrolysis is a unique and sustainable method of energy recovery. The use of accessible and affordable bentonite clay in pyrolysis could considerably help in the reuse of plastic wastes. This review paper provides a comprehensive overview of the current state of knowledge on pyrolysis technology for plastic waste management, with a specific focus on the use of life cycle assessment (LCA) methodology. The study reviews pyrolysis research from the past and now, discussing its environmental advantages, catalytic and thermal yield, and potential for further study. The report also explores several possible pyrolysis technology constraints and other plastic waste end-of-life solutions. The findings of the review point out the promising potential of pyrolysis as an eco-friendly technique for handling plastic waste and outline areas that require additional study and improvement. The findings presented in this review can be used by policymakers, practitioners, and other stakeholders to solve the plastic waste issue and make well informed choices.
