A plastic film that can kill viruses using room lights
Phys.org
Researchers at Queen's University Belfast have developed a plastic film that can kill viruses that land on its surface with room light. The self-sterilizing film is the first of its kind — it is low cost to produce, can be readily scaled and could be used for disposable aprons, tablecloths, and curtains in hospitals. It is coated with a thin layer of particles that absorb UV light and produce reactive oxygen species — ROS.

Resin price report: New signs point to market rebound
Plastics Today
In last week’s column reporting on resin trading activity during the week of Aug. 22, we wondered if resin pricing had found a bottom. That may have been prescient . . . or premature. Reporting on spot resin trading the week of Aug. 29, the PlasticsExchange notes in its Market Update that activity has improved amid volatile pricing, which might ultimately prove to be "bottoming activity."

How to make recyclable plastics out of CO2 to slow climate change
ScienceNews
It’s morning and you wake on a comfortable foam mattress made partly from greenhouse gas. You pull on a T-shirt and sneakers containing carbon dioxide pulled from factory emissions. After a good run, you stop for a cup of joe and guiltlessly toss the plastic cup in the trash, confident it will fully biodegrade into harmless organic materials.

Shining light on why plastics turn yellow
American Chemical Society via ScienceDaily
If you own a retro gaming console or have an old roll of packing tape, you've seen how plastics turn yellow as they age. Though the cause of this color change has long been attributed to the formation of molecules that act as dyes — the actual chemical changes that take place remained unexplained. Now, researchers have identified surface-based chiral nanostructures as the potential culprit.

Researchers use X-rays to turn plastic into diamonds — seriously
Green Matters
In efforts to create more ethically-sourced options in the diamond market, lab-grown diamonds have been on the rise in recent years. But now there’s a new way of creating diamonds in a lab: by using laser beams to recycle plastic into diamonds — more specifically, nanodiamonds. But what are nanodiamonds exactly?

Scientists develop unique method of making 3D printed polymer lattices 100-times stronger
3D Printing Industry
Researchers at the City University of Hong Kong have come up with a way of making 3D printed polymeric lattice parts 100-times stronger than before.
Compared to traditional heat treatments, which strengthen plastic printed objects at the cost of deformability, the CityU approach only partially carbonizes them, to make them more robust and twice as ductile.

Bio-based packaging companies say mushrooms and seaweed are the next alternatives to plastic
Waste Dive
As major brands continue to pledge to reduce plastic packaging, bio-based packaging companies have positioned themselves as alternatives to recycled plastic products by offering options made with seaweed and mushrooms.
During an Aug. 25 webinar hosted by the Plastic Pollution Coalition, representatives from Ecovative, Loliware and Sway discussed how such packaging can help companies meet plastic reduction targets and fit into existing supply chains.

Promoted by Polyfil
 Polyfil, a Kafrit Group company, together with Kafrit IL and N3Cure (an Israeli based Start Up) provides solutions for UV curing systems and CROSSITOL® masterbatches. Crosslinking enables the production of recyclable packaging with a single-polymer structure (Mono-material), saving costs and reducing the consumption of fossil-based polymers. As a result, it will have a smaller effect on the environment than most plastic solutions.
CROSSITOL® masterbatches can be used in a wide range of applications including cast and blown film extrusion. Its technology is coupled with N3Cure’s curing system to target specific layers for crosslinking, downgauging, and production costs.

Model bill for reuse of resins proposed
Recycling Today
The Northeast Recycling Council and Northeast Waste Management Officials’ Association have announced the publication of its Model Minimum Postconsumer Recycled Content Requirements for Plastic Products and Packaging Legislation. This model is the result of two years’ worth of work by a group of state recycling officials from the Northeast and incorporates many suggestions received from 36 organizations and individuals during a public comment period in early 2022.
