25 Ιαν 2022 · Every step of circulating and recycling leads to downgrading and loss of material. Fresh material has to be added to achieve certain grades of recycled plastics or polymers.
STEM projects using recycled materials will help kids (and adults) create sustainable solutions to complex problems in their future careers that could one day save our planet. Teachers and parents can equip children receiving a STEM education with the skills needed to develop innovative solutions for fulfilling specific needs.
16 Νοε 2022 · The move to a circular economy — a system that aims to reduce, reuse and recycle materials — could address 70% of global greenhouse emissions 1. As the benefits stack up, this transition is...
10 Αυγ 2023 · The circularity concept aims to create a closed-loop system in which plastic waste is minimized and materials are continuously produced (orange); used, collected, and sorted (blue); and recycled and regenerated (green).
17 Νοε 2017 · Cheap, light, and versatile, plastics are the dominant materials of our modern economy. Their production is expected to double over the next two decades. Yet, only 14% of all plastic packaging is collected for recycling after use, and vast quantities escape into the environment.
25 Ιαν 2021 · Scientists are particularly interested in finding a process to upcycle polyolefins, one of the cheapest, most common types of plastics. They’re used in many single-use plastic products, like grocery bags. Two Office of Science-supported studies have used a platinum-based catalyst to transform plastic.
