Sustainability Assessment of Mechanochemistry by Using the Twelve Principles of Green Chemistry

ChemSusChem, Journal Year: 2021, Volume and Issue: 14(10), P. 2145 - 2162

Published: April 9, 2021

In recent years, mechanochemistry has been growing into a widely accepted alternative for chemical synthesis. addition to their efficiency and practicality, mechanochemical reactions are also recognized sustainability. The association between Green Chemistry often originates from the solvent-free nature of most protocols, which can reduce waste production. However, satisfies more than one Principles Chemistry. this Review we will present series examples that clearly illustrate how significantly contribute fulfillment in holistic manner.

Published: May 2, 2021

The polyethylene terephthalate (PET) application has many challenges and potential due to its sustainability. conventional PET degradation was developed for several technologies get higher yield products of ethylene glycol, bis(2-hydroxyethyl terephthalate) terephthalic acid. chemical recycling is reviewed, such as pyrolysis, hydrolysis, methanolysis, glycolysis, ionic-liquid, phase-transfer catalysis combination glycolysis–hydrolysis, glycolysis–methanolysis methanolysis–hydrolysis. Furthermore, the reaction kinetics conditions were investigated both theoretically experimentally. solve environmental problems find another source raw material petrochemical energy.

Depolymerization within a Circular Plastics System

Chemical Reviews, Journal Year: 2024, Volume and Issue: 124(5), P. 2617 - 2650

Published: Feb. 22, 2024

The societal importance of plastics contrasts with the carelessness which they are disposed. Their superlative properties lead to economic and environmental efficiency, but linearity puts climate, human health, global ecosystems at risk. Recycling is fundamental transitioning this linear model into a more sustainable, circular economy. Among recycling technologies, chemical depolymerization offers route virgin quality recycled plastics, especially when valorizing complex waste streams poorly served by mechanical methods. However, exists in interlinked system end-of-life fates, complementarity each approach key environmental, economic, sustainability. This review explores recent progress made five commercial polymers: poly(ethylene terephthalate), polycarbonates, polyamides, aliphatic polyesters, polyurethanes. Attention paid not only catalytic technologies used enhance efficiencies also interrelationship other systemic constraints imposed Novel polymers, designed for depolymerization, concisely reviewed terms their underlying chemistry potential integration current plastic systems.

Mechanochemical Degradation and Recycling of Synthetic Polymers

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(27)

Published: April 1, 2023

Abstract The accumulation of plastic waste, due to lack recycling, has led serious environmental pollution. Although mechanical recycling can alleviate this issue, it inevitably reduces the molecular weight and weakens properties materials is not suitable for mixed materials. Chemical on other hand, breaks polymer into monomers or small‐molecule constituents, allowing preparation quality comparable that virgin polymers be applied Mechanochemical degradation leverages advantages techniques, such as scalability efficient energy use, achieve chemical recycling. We summarize recent progress in mechanochemical synthetic polymers, including both commercial those designed more degradation. also point out limitations present our perspectives how challenges mitigated a circular economy.
