Zero-waste circular economy of plastic packaging: The bottlenecks and a way forward

Sustainable materials and technologies, Journal Year: 2023, Volume and Issue: 38, P. e00735 - e00735

Published: Sept. 30, 2023

Interest in recycling is higher than ever, with the of plastic packaging waste being a significant concern for general public and governments worldwide. However, rate has stagnated over past five years. This implies current strategies are insufficient new approaches required. We evaluate present situation highlight bottlenecks that limiting efficient recovery using currently available systems. Difficult to recycle thermoplastics such as polystyrene poly(vinyl chloride) not needed packaging, which we propose should be based on poly(ethylene terephthalate) (PET), polypropylene (PP), high-density low-density polyethylene (HDPE LDPE respectively). Furthermore, draw attention opportunity keeping PET/PP single stream, leaving HDPE standalone enable separation individual types mechanical achieve zero-waste circular economy all packaging.

Economic and environmental optimisation of mixed plastic waste supply chains in Northern Italy comparing incineration and pyrolysis technologies

Computers & Chemical Engineering, Journal Year: 2023, Volume and Issue: 180, P. 108503 - 108503

Published: Nov. 11, 2023

In the quest for sustainable plastic waste management, understanding economic and environmental implications enables optimal selection of treatment technologies. This study presents a multi-objective mixed integer linear programming framework to optimise supply chain in Northern Italy. Two technologies are considered: incineration pyrolysis. Results offer quantitative insights into performance, balancing trade-offs between maximising gross profit minimising greenhouse gas (GHG) emissions. Economic optimisation favours treating waste, resulting highest 115 M€ per year, net GHG emissions about 680 kt CO2eq year. When aim is optimisation, pyrolysis preferred due its lower 387 year yielding 54 Trade-off Pareto solutions were analysed identify reasonable trade-off configurations two objectives.

Toward Building Circularity in Sustainable Plastic Waste Conversion

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(23), P. 8642 - 8661

Published: May 31, 2024

The escalating levels of plastic waste have created an urgent need for sustainable recycling methods aligned with the circular economy (CE) goals. Leveraging process systems engineering (PSE) models, which facilitate sustainability-driven problem-solving, this work proposes a comprehensive mathematical framework optimizing diverse technologies─pyrolysis, gasification, mechanical recycling, and incineration─balancing economic feasibility CE contributions. Recognizing versatility chemical derivatives, model explores their applications in methanol ammonia synthesis, hydrogen production, more, emphasizing waste's potential to yield energy valuable products through open- closed-loop pathways. A novel metric was introduced assess pathways across critical indicators. An illustrative case study 20 scenarios highlights pyrolysis refinery technology as promising fuel olefin tripling profitability, improving circularity by over 25%. Combining synthesis maximizes 44% enhancement. flexible weight allocation individual metrics during optimization emphasis on tailored solutions system-specific needs. Comparative analyses between conventional feedstocks unveil cost-effective landscape that is dependent product. Capacity-level sensitivity analysis consistently demonstrates superior performance optimal compared base regarding profitability.
