🦠 Emerging Biochemical Conversion for Plastic Waste Management: A Review

mdpi.com/1420-3049/30/6/1255

MDPIEmerging Biochemical Conversion for Plastic Waste Management: A ReviewIn recent years, vast amounts of plastic waste have been released into the environment worldwide, posing a severe threat to human health and ecosystems. Despite the partial success of traditional plastic waste management technologies, their limitations underscore the need for innovative approaches. This review provides a comprehensive overview of recent advancements in chemical and biological technologies for converting and utilizing plastic waste. Key topics include the technical parameters, characteristics, processes, and reaction mechanisms underlying these emerging technologies. Additionally, the review highlights the importance of conducting economic analyses and life cycle assessments of these emerging technologies, offering valuable insights and establishing a robust foundation for future research. By leveraging the literature from the last five years, this review explores innovative chemical approaches, such as hydrolysis, hydrogenolysis, alcoholysis, ammonolysis, pyrolysis, and photolysis, which break down high-molecular-weight macromolecules into oligomers or small molecules by cracking or depolymerizing specific chemical groups within plastic molecules. It also examines innovative biological methods, including microbial enzymatic degradation, which employs microorganisms or enzymes to convert high-molecular-weight macromolecules into oligomers or small molecules through degradation and assimilation mechanisms. The review concludes by discussing future research directions focused on addressing the technological, economic, and scalability challenges of emerging plastic waste management technologies, with a strong commitment to promoting sustainable solutions and achieving lasting environmental impact.

Opposition parties urge Quebec not to ram through Blainville toxic waste dump legislation
Bill 93 would force the City of Blainville to sell a piece of land to a private company to expand its toxic waste dump. Opposition parties are worried the CAQ government is preparing to invoke closure and force the law through.

Pres. Donald Trump is reducing necessary government services to save money, which he will waste on more tax cuts for the rich, but he talks like he has enough money to buy Greenland, and even to "compensate people who were prosecuted for taking part in the riot at the Capitol in 2021." First he pardoned violent thugs and now he wants taxpayers to pay them:
