Using a natural chlorite as catalyst in chemical recycling of waste plastics: Hydrolytic depolymerization of poly-[bisphenol A carbonate] promoted by clinochlore

The organic chemistry behind the recycling of poly(bisphenol‐A carbonate) for the preparation of chemical precursors: A review

“…However, the catalytic activity of chlorite clearly decreased when it was reused in subsequent cycles. 106 Although heterogeneous catalysts and ILs are promising alternatives for smoothing hydrolysis conditions, more research will be needed to establish economically viable and industrially applicable protocols. In this line, the use of organic solvents and inorganic bases as additives remains the most practical and affordable alternative.…”

Selective, Sequential, and “One-Pot” Depolymerization Strategies for Chemical Recycling of Commercial Plastics and Mixed Plastics

“…The commercial plastics that are currently used in a large-scale are primarily concerned with performance and durability rather than degradability and recyclability. As a result, the chemical recycling of plastics becomes a significant challenge. − Fortunately, polyester and polycarbonate plastics offer an opportunity for plastic sustainability due to the presence of easily cleaved carbon–oxygen bonds in the polymer backbones. − At present, studies on the conversion of polyester and polycarbonate materials such as poly­(ethylene terephthalate) (PET), − polylactide (PLA), − poly­(bisphenol A carbonate) (BPA-PC), − into starting monomers, or value-added chemicals have been widely reported, which are of great significance for plastic sustainability. The depolymerization of a single polyester has been investigated intensively.…”

High throughput investigation of an emergent and naturally abundant 2D material: Clinochlore

“…Previous works on its 3D-bulk form have been carried out to elucidate its optical, mechanical and electric properties [32][33][34]. Clinochlore has also been applied to diverse fields, such as prebiotic synthesis and polymerization of biomolecules [35], catalyst in the chemical recycling of waste plastics [36], for room-temperature synthesis of triazole compounds in water [37], and decontamination of water resources [38]. Furthermore, the geological importance of clinochlore in the study of mineral formation [39,40] and hydration/weathering processes at nanoscale [41] remains a topic of current relevance, as well as its mechanical behavior under pressure [42,43].…”
