Chemical and biological catalysis for plastics recycling and upcycling

چکیده
Plastics pollution is causing an environmental crisis, prompting the development of new approaches for recycling, and upcycling. Here, we review challenges opportunities in chemical biological catalysis plastics deconstruction, We stress need rigorous characterization use widely available substrates, such that catalyst performance can be compared across studies. Where appropriate, draw parallels between on biomass plastics, as both substrates are low-value, solid, recalcitrant polymers. Innovations design reaction engineering needed to overcome kinetic thermodynamic limitations deconstruction. Either catalysts will act interfacially, where function at a solid surface, or polymers solubilized processed smaller intermediates facilitate improved catalyst–substrate interaction. Overall, developing catalyst-driven technologies deconstruction upcycling critical incentivize reclamation reduce severe global burden plastic waste. invaluable materials modern society, although they result generation large amounts litter end their life cycle. This Review explores associated with catalytic transformation waste looking transforming spent into resource.

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
Plastics recycling: challenges and opportunities.
Plastics are inexpensive, lightweight and durable materials, which can readily be moulded into a variety of products that find use in a wide range of applications. As a consequence, the production of plastics has increased markedly over the last 60 years. However, current levels of their usage and disposal generate several environmental problems. Around 4 per cent of world oil and gas productio...
