Vacuum residue (VR) was copyrolysed with polyethylene (PE) or polystyrene (PS) in a batch reactor to investigate the corresponding synergistic pyrolytic interactions. The interactions between VR and plastic pyrolysates enhanced liquid gas production while reducing coke formation, as compared VR-only plastic-only pyrolysis. pyrolysis of 9:1 w/w VR: PE

A powerful toolbox is needed to turn the linear plastic economy into circular. Development of materials designed for mechanical recycling, chemical and/or biodegradation in targeted end-of-life environment are all necessary puzzle pieces this process. Polyesters, with reversible ester bonds, already forerunners circularity: poly(ethylene terephthalate) (PET) most recycled material suitable and while common aliphatic polyesters biodegradable under favorable conditions, such as industrial compost. However, circular design needs be further tailored different options enable recycling greener conditions rapid enough even less environmental conditions. Here, we discuss molecular polyester chain targeting enhancement circularity by incorporation more easily hydrolyzable additional dynamic or degradation catalyzing functional groups part chain.

Plastic pollution has escalated into a critical global issue, with production soaring from 2 million metric tons in 1950 to 400.3 2022. The packaging industry alone accounts for nearly 44% of this production, predominantly utilizing polyethylene terephthalate (PET). Alarmingly, over 90% the approximately 1 PET bottles sold every minute end up landfills or oceans, where they can persist centuries. This highlights urgent need sustainable management and recycling solutions mitigate environmental impact waste. To better understand PET's behavior promote its within circular economy, we examined chemical physical properties, current strategies most effective methods available today. Advancing economy framework by closing industrial loops demonstrated benefits such as reduced landfill waste, minimized energy consumption, conserved raw resources. end, identified various based on R-imperatives (ranging 3R 10R), focusing latest approaches aimed at significantly reducing waste 2040. Additionally, comparison (including primary, secondary, tertiary, quaternary recycling, along concepts "zero-order" biological techniques) was envisaged. Particular attention paid heterogeneous catalytic glycolysis, which stands out rapid reaction time (20-60 min), high monomer yields (>90%), ease catalyst recovery reuse, lower costs, enhanced durability. Accordingly, use highly efficient oxide-based catalysts glycolytic degradation is underscored promising solution large-scale applications.

The global plastic waste crisis stems from unsustainable design and a linear economy that leads to massive environmental pollution. Polyethylene terephthalate (PET), widely used in packaging textiles is one of the primary contributors this issue. While mechanical recycling PET results degraded material quality, chemical offers promising alternative, enabling transformation into valuable monomers precursors. In study, postconsumer chemically upcycled bifunctional aromatic amine can serve as an effective building block for polyhexahydrotriazine (PHT) aerogels. Additionally, terephthalamide moieties incorporated molecular design, enhance formed network by hydrogen bonding. resulting PHT aerogels exhibit low density, high robustness, outstanding thermal insulation properties. More importantly, these novel are designed recyclability, depolymerization under aqueous acidic conditions efficient monomer recovery yield purity. recycled then be immediately reused produce new with nearly identical This work highlights potential upcycling sustainable thermally superinsulating materials circular economy.
