Plastic

Researchers working to trace the path of plastic waste through the marine environment have discovered the highest concentration of microplastics ever recorded on the seafloor, the result of deep-sea currents that act like conveyor belts for our trash.

Scientists at Cornell University have been working on more environmentally friendly forms of plastic for the fishing industry, and have come up with a new plastic material that can break down much more quickly when exposed to UV light.

Scientists at Cardiff University have come up with a way of estimating the maximum size of plastic pieces different marine creatures can consume, which could help assess the risks different types of waste pose to species around the globe

Biologists working at Canada’s Brandon University have made an exciting discovery, zeroing in on the mechanisms that enable a common species of caterpillar to survive on a diet of plastic alone.

Research from a team of US scientists is again raising doubt over the safety of “BPA-free” plastic products. The animal studies described in a new article suggest bisphenol S (BPS) “causes almost identical changes in gene expression” compared to BPA.

We've recently heard about a number of experimental antibacterial food-wrap films, that could replace conventional polyethylene. The latter does have some desirable qualities, though, so scientists have now developed a composite made from it.

With gold, beauty and weight are two sides of the same coin. Now, by mixing it with plastic instead of other metals, researchers have created a new form of gold with as little as one-10th the usual weight, but retaining the same purity.

Scientists tinkering with the chemical processes underpinning plastics recycling are continually uncovering new ways to put the discarded material to use. Here are five examples of such technologies that give hope of a greener future.

The bananas that we buy in stores grow off of a central trunk-like structure, known as the pseudostem. And while that part of the plant is typically discarded during harvesting, it may soon find use in a plastic that biodegrades and is recyclable.

Take a walk along the canal in Amsterdam’s Westerdok district, and you may see an unsightly mess of waste gathered at the edge of the canal. What you’re seeing is the work of a new bubble barrier, designed to stop plastic waste flowing out to sea.

BioBag World Australia and IG Fresh Produce have come up with an alternative to polyethylene wrap that can be used to keep cucumbers fresh.

The vast majority of plastic waste can’t be recycled, meaning it ends up in landfills or the ocean. To help curb the problem, researchers at Berkeley Lab have now designed a new type of plastic that can apparently be reduced right back to its molecular parts, before being remade over and over.
