Polyethylene terephthalate (PET) and CO2 , two chemical wastes that urgently need to be transformed in the environment, are converted simultaneously a one-pot catalytic process through synergistic coupling of three reactions: hydrogenation, PET methanolysis dimethyl (DMT) hydrogenation. More interestingly, equilibria both reactions were shifted forward due revealed dual-promotion effect, leading significantly enhanced depolymerization. The overall methanol yield from hydrogenation exceeded original thermodynamic equilibrium limit since was situ consumed methanolysis. degradation by stoichiometric ratio because primary product, DMT hydrogenated cyclohexanedicarboxylate (DMCD) or p-xylene (PX). This provides an effective way recycle wastes, polyesters for producing high-value chemicals.

There are increasing concerns over the threat of nanoplastics to environmental and human health. However, multidisciplinary barriers persist between communities assessing risks As a result, hazards remain uncertain. Here, we identify key knowledge gaps by evaluating exposure in environment, their bio-nano interactions, examining potential humans environment. We suggest considering complex dynamic mixture polymers, additives, contaminants, with interconnected call for comprehensive integration One Health approach produce robust evidence threats at planetary level. Although there many challenges, this holistic incorporates relevance multi-sectoral responses, which provide opportunity risk mitigation strategies build resilient health systems.
