Plastics of the future will live many past lives, thanks to chemical recycling
CU Boulder Today
One day in the not-too-distant future, the plastics in our satellites, cars and electronics may all be living their second, 25th or 250th lives.
New research from CU Boulder, published in Nature Chemistry, details how a class of durable plastics widely used in the aerospace and microelectronics industries can be chemically broken down into their most basic building blocks and then formed once again into the same material.

Resin price report: Tropical storm Ian batters Florida but spares petrochemical infrastructure
Plastics Today
Hurricane season has come to life in what is typically a more active cycle in September/October, reports the PlasticsExchange in its Market Update.
At the time of writing, Tropical Storm Ian has wreaked havoc across much of central and northeastern Florida since hitting the mainland, but it has spared the Texas and Louisiana refining and petrochemical infrastructure.

Scientists speed up 3D printing by combining resin
AZO Materials
3D printing breakthroughs have made it possible for engineers and designers to personalize projects, create physical prototypes at various scales, and build structures that were previously impossible to produce using more conventional manufacturing methods. However, the process is time-consuming and demands specific elements that must be used one at a time.

Process converts polyethylene bags, plastics to polymer building blocks
Phys.org
Polyethylene plastics — in particular, the ubiquitous plastic bag that blights the landscape — are notoriously hard to recycle. They're sturdy and difficult to break down, and if they're recycled at all, they're melted into a polymer stew useful mostly for decking and other low-value products.

AI-engineered plastic-eating enzyme could be the solution to plastic pollution
Earth.org
Research suggests that the world is generating twice as much plastic as it did two decades ago, with the majority of it either getting incinerated or ending up in landfills or dispersed in the environment, especially in oceans.
According to the Global Plastics Outlook report published by the Organisation for Economic Co-operation and Development, only 9% of plastic is successfully recycled while 22% of plastic is mismanaged.

These new plastics offer tasty meals to marine life (and can reduce pollution)
Inverse
When plastic was first introduced in 1907, it was hailed as a miracle material. The petroleum-based substance could seemingly do anything — harden into a rock-solid car part or a flexible waterproof coating, stretch into fibers, froth into foam, and take on any shade (from the deepest black to stark white to translucent).

Designing a new upcycling system for synthetic polyesters
AZO Materials
Although plastics and synthetic polymers have a variety of beneficial qualities, poor management has led to extensive pollution that harms our ecosystems. Polyethylene terephthalate, one of the most popular materials usually found in the recycling loop in many countries, is one of the synthetic polymers sent for reprocessing and recycling as a remedy for this.

A surprising product from waste plastic — vanillin
ABC
Molecular chemist Joanna Sadler saw a familiar shape in the molecules making PET bottles. They reminded her of vanillin, the flavor extracted from vanilla beans. Vanillin is ubiquitous in the food and cosmetic industries, and an important bulk chemical. So she wrote code for DNA and inserted it into the bacteria E.coli.

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.

Why the plastics industry should embrace carbon accounting
Plastics Today
Despite major efforts by environmentalists to spread the word about the dangers of plastic to our environment, plastic consumption and production are actually rising across the globe. This means that, in addition to the harm that plastic waste does to our oceans and wildlife, we need to contend with the expanding carbon footprint of the plastics production process.
