Hace 4 días · Chemical upcycling, a conversion of discarded plastics to higher-value materials or feedstocks, is another approach to resolve plastic pollution. 18–24 One specific example is oxidative degradation, which uses thermally induced radicals and a cheap oxidant, molecular oxygen (O 2), to cleave polymer chains and produce small molecule oxidized compounds. 25,26 In the environment, plastics ...
Hace 4 días · Blog Liv Johansson 06/17/2024. Compelled and concerned by the proliferation of compostable plastics in commercial compost feedstock streams, ECS developed a research plan to test certified compostable plastic degradation rates in our laboratory. On May 20 th, Biocycle published an article detailing this research in depth.
Hace 1 día · Around 0.5 per cent of all plastic waste enters the ocean. This may not seem like much, but when the total amount of plastic generated each year totals approximately 350 million t, that means anywhere between one and two million t of plastic ends up polluting the world’s oceans, according to the OECD. These five graphs explore: the share of ...
Hace 3 días · The physical and mechanical properties of the developed plastic films, such as thickness, tensile strength (TS), water vapor transmission rate (WVTR), oxygen transmission rate (OTR) and color, were tested for packaging applications in the food industry.
Hace 4 días · Multiply the amount by its approximated weight. A PET bottle weights around 25 grams: 3 × 0.025 kg = 0.075 kg/week. Calculate the total footprint over time. Multiply the footprint per week to 52 for your yearly plastic footprint (or by 12 if your unit is per month): 0.075 × 52 = 3.9 kg/year. That's it!
Hace 4 días · This tutorial review presents an overview of oxidative degradation, from its earliest examples to emerging strategies. This review briefly discusses the motivation and the development of thermal oxidative degradation of polymers with a focus on underlying mechanisms.
Hace 5 días · Globally, we produced 489 million tonnes of plastic in 2023 and we recycled only 8.17%. This study navigates the landscape of recycling practices, highlighting the imperative to reevaluate and upgrade industry-standard protocols. The central focus of this study is on integrating more robust traceability criteria and advanced quality testing methodologies to improve recycled plastics with ...
