Sugar-based recyclable plastic developed

Researchers from the University of Birmingham, U.K., and Duke University, U.S., have created a new family of polymers from sustainable sources that retain all of the same qualities as common plastics, but are also degradable and mechanically recyclable. The scientists...

Understanding fountain flow in injection molding

To mold acceptable parts that meet cosmetic and dimensional specifications, it is important to understand the basics of fountain flow and how it exerts itself throughout the entire molding process. In thermoplastic injection molding, the mold is always said to be “cold”...

Polymer upcycling of common plastic adds toughness, recyclability to structural adhesives

Researchers at the Department of Energy's Oak Ridge National Laboratory used polymer chemistry to transform a common household plastic into a reusable adhesive with a rare combination of strength and ductility, making it one of the toughest materials ever reported.

Turning plastics back into petrochemicals

Despite efforts to promote recycling and reuse of plastic materials, the plastic problem continues to be a global problem. West Virginia University engineers hope to debottleneck the remaining challenges for recycling of single-use plastic packaging by upcycling them into...

Plastic scrap markets to benefit from growing demand

Plastic scrap generation has slowed as is typical in the early part of each year, which is serving to increase or maintain pricing. “Availability is tight and pricing for scrap is steady to increasing,” a Midwest-based reprocessor of rigid polyolefin scrap says. A...

Researchers design a bioplastic from mango peel, hibiscus and roasted coffee residues

A group of Mexican researchers has studied the effect of adding the by-products of mango, hibiscus, and coffee in the development of bioplastics made from starch. Starch is a natural polymer and the material most widely used...

Extrusion and the shape of water management

So spoke the Ancient Mariner in Coleridge’s Rime of the Ancient Mariner (1797). He was out there in the open sea, cursed for having killed an albatross (good luck to sailors), and had a real problem. He didn’t know why we don’t drink sea water — it’s...

Using recycled plastic to make airplane wiring reaps environmental benefits

Airplane wiring soon could be made of recycled plastic, and that would have a stunning impact on aircrafts’ carbon footprints. An article in The Conversation by Alvin Orbaek White, a Senior Lecturer in engineering at Swansea...

Iowa puts recycled plastic roads to the test

Iowa is testing a new recycled plastic mixture in asphalt in several spots across the metro in hopes of extending the life of roadways. Why it matters: Inclement Iowa weather, like today's Saskatchewan screamer, can take a serious toll on our roads. Taxpayers could save...

The changing nature of injection molding

A year ago, as the first images of healthcare workers being vaccinated against COVID-19 were broadcast, and well before we all began an unwanted lesson in the Greek alphabet, I would not have thought my predictions post for 2022 would mention the “C” word through...

Chemical recycling and supercritical steam among latest innovations driving the circular economy for plastics

There is more innovation in plastics recycling currently than for any other material. One of the key trends in this sector is the growing use of pyrolysis and other forms of chemical recycling to reduce materials...
