Envisioning a BHET Economy: Adding Value to PET Waste

Sustainable Chemistry, Год журнала: 2023, Номер 4(4), С. 363 - 393

Опубликована: Дек. 18, 2023

Poly(ethylene terephthalate), the fifth most produced polymer, generates significant waste annually. This increased production has spurred interest in chemical and mechanical pathways for recycling. The shift from laboratory settings to larger-scale implementation creates opportunities explore value recovery of recycling products. Derived glycolysis PET, bis(2-hydroxyethyl) terephthalate (BHET) exhibits versatility as a depolymerization product valuable monomer. BHET finds application across diverse industries such resins, coatings, foams, tissue scaffolds. Incorporating BHET, which is product, supports higher rates contributes more sustainable approach generating materials. review illuminates feedstock circular polymer materials economy.

Analyses of circular solutions for advanced plastics waste recycling

Nature Chemical Engineering, Год журнала: 2024, Номер 1(10), С. 615 - 626

Опубликована: Окт. 10, 2024

A circular plastics economy can leverage the lightweight, strong and durable characteristics of macromolecular materials, while simultaneously reducing negative environmental impacts associated with polymer waste. Advanced recycling technologies provide an opportunity to valorize waste extend lifespan these materials by converting into new monomers, polymers or specialty chemicals. Although many advanced appear promising, assessments economic sustainability are often not conducted in a standardized fashion neglect factors such as transportation, sorting pretreatment. These shortcomings lead inaccurate misleading predictions, reduce opportunities for optimization limit industrial relevance. In this Review, we highlight select case studies underscore notable consequences underestimating complexity real-life consumer addition, current challenges assessment viability laboratory-scale processes explored. By discussing relevant analysis frameworks system boundaries, along potential analytical pitfalls, future research will be guided beyond chemical considerations toward impactful solutions. is end-of-life option generation high-value products. This Review highlights importance developing holistic analyses candidate technologies, focus on key parameters, complexities infrastructure, scale-up considerations, trade-offs.

Circularizing PET-G Multimaterials: Life Cycle Assessment and Techno-Economic Analysis

ACS Sustainable Chemistry & Engineering, Год журнала: 2023, Номер 11(42), С. 15328 - 15337

Опубликована: Окт. 13, 2023

The recycling of multimaterials such as payment or access cards poses significant challenges. Building on previous experimental work demonstrating the feasibility chemically recyclable made from glycol-modified poly(ethylene terephthalate) (PET-G), we use life cycle assessment and techno-economic analysis to investigate two chemical scenarios evaluate their potential environmental economic benefits. Recovering all components depolymerized products (Scenario 1) achieves substantial benefits across most categories, reducing global warming by up 67% compared only recovering major 2). However, in Scenario 1 incur 69% higher total annualized costs, causing its profitability be dependent a minimum selling price £13.4/kg for cyclohexanedimethanol less than 10% discount rate. In contrast, 2 is sensitive rate variation thus lower risk more economically feasible option, albeit environmentally sustainable.
