A review of the cost and effectiveness of solutions to address plastic pollution

Josiane Nikiema et al.

Summary: Plastic usage is increasing year by year, with a low recycling rate, resulting in significant environmental and economic impacts. This review summarizes key solutions to address plastic and microplastic contamination from source to sea, including controlling plastics in solid wastes, in water streams, and microplastics, as well as implementing general policy measures. The guidance provided can help policymakers and practitioners address the plastic and microplastic management problem in a sustainable and cost-efficient way.

Influence of the catalytic system on the methanolysis of polyethylene terephthalate at mild conditions: A systematic investigation

Flavio Tollini et al.

Summary: Plastic disposal poses a threat to the environment due to the lack of cost-effective technologies for producing high-quality polymers from scraps. This study investigates the efficiency of different catalytic systems in the methanolysis of PET and identifies potassium carbonate and dichloromethane as the most effective catalyst/cosolvent pair.

Mechanical Recycling of Packaging Plastics: A Review

Zoe O. G. Schyns et al.

Summary: The current global plastics economy is linear, but transitioning to a circular economy is crucial for reducing environmental impacts through degradation, reuse, and recycling. Mechanical recycling plays a key role in a sustainable plastic economy, but challenges such as high costs, mechanical property degradation, and inconsistent product quality need to be addressed.

Chemolytic depolymerisation of PET: a review

Elaine Barnard et al.

Summary: Developing new methods for plastic recycling is crucial for reducing CO2 emissions and improving resource efficiency. Chemical recycling, which involves depolymerization to reclaim original components, is gaining attention as a viable route. Lowering the energy barrier for depolymerization through catalysts under mild conditions is a key focus of research in this field.

Low-energy catalytic methanolysis of poly(ethyleneterephthalate)

Duong Dinh Pham et al.

Summary: In this study, a low-energy catalytic route for methanolysis to convert PET resin to DMT was developed, achieving high DMT selectivity at ambient temperature by controlling the moisture level. The PET depolymerization apparently proceeded through two series of reaction steps, and the degradation of PET had a relatively low activation energy of 66.5 kJ mol(-1), which was accountable for catalytic methanolysis of PET at ambient conditions.

Removal of trace amount impurities in glycolytic monomer of polyethylene terephthalate by recrystallization

Junjie Huang et al.

Summary: A modified recrystallization process using ethyl acetate as the solvent successfully removed colored impurities from BHET with a decoloring rate of over 97.5%, outperforming traditional physical adsorption processes. By combining with activated carbon adsorption, the whiteness of BHET greatly increased, showing the potential for achieving closed-loop recycling of dark PET fibers.
