Scientists at King’s College London have unveiled a groundbreaking method for recycling single-use bioplastics, commonly found in disposable items like coffee cups and food containers. Published in Cell Reports Physical Science, the chemical recycling approach utilizes enzymes akin to those in biological laundry detergents to swiftly break down landfill-bound bioplastics within just 24 hours.

Advanced machinery that can effectively decontaminate post-consumer plastics is the key to producing rPET with exceptionally high purity. This quality is essential for FDA-approved food-grade packaging.

The Consumer Goods Forum (CGF) has established 9 Golden Design rules to tackle plastic pollution. Rule #1 is to increase the value of PET recycling by embracing transparency and simplicity.

A pair of U.S. defense-related organizations –– America Makes and NCDMM –– have awarded funds to a project designed to optimize recycled PET (rPET) and rPET-based composites in filament-fed material extrusion 3D printing.

As scientists, we must look for the truth, but sometimes this truth can be interpreted differently depending on how our investigation scope was developed. I think this is the case of the recent study that found hundreds of thousands of nanoplastics in bottled water.

Injection molding simulation has already achieved a high level of precision. Industry leaders’ recent collaboration promises enhanced precision in material data, elevating manufacturing efficiency and quality standards.

Research indicates that microplastics induce physiological and behavioral changes in aquatic organisms, impacting reproductive capabilities and overall fitness. Furthermore, microplastics serve as carriers for toxic chemicals, posing additional threats as they traverse through the food web.

Companies worldwide are gathering efforts to develop flame retardant systems based on renewable sources providing an eco-friendly alternative to halogenated flame retardants. Additives with flame-retardant properties, such as phosphorus-based compounds, can chemically modify carbon sources like cellulose, chitosan, and lignin. This results in the successful design of intumescent flame retardants for use in many applications.

The emergence of hydrogel and aerogel-based flame-retardant polymeric materials marks new and innovative options in fire safety and protection. Henri Vahabi and his team’s review article for the SPE Journal of Vinyl and Additive Technology thoroughly explores this cutting-edge concept, revealing its makeup, capabilities, and potential future developments of these innovative materials.

Melt Electrowriting (MEW) emerged in the biomedical and tissue engineering outlook over a decade ago as a method for printing structures on the low micrometer or nanometer scale. But how does it work, and what does the future hold for this technology?

Perstorp Group today introduced a more sustainable, phthalate-free grade of PVC plasticizer called Pevalen Pro 100 that features 100 percent renewable carbon content based on mass balance.

Plastic materials selection involves choosing materials that meet some important characteristics like performance, cosmetics, and costs. But there is not a playbook for doing materials selection. On the contrary, this means doing some property research, taking into account product lifetime and even in some cases, regulation.
