Levi's will incorporate 3.5 million bottles into its Waste

American clothing maker and denim specialist Levi Strauss & Co. has announced a new collection of denim apparel, including jeans, that will be comprised of a minimum 20 percent of plastics recycled from drinks bottles and food trays.  Read More

Collecting plastic nurdles with the 'Nurdler'

You may have heard about the huge floating islands of garbage swirling around in the middle of the Earth's oceans. Much of that waterlogged rubbish is made up of plastic and, like Electrolux with its concept vacuum cleaners, U.K.-based Studio Swine and Kieren Jones are looking to put that waste to good use. As part of an ambitious project, they’ve come up with a system to collect plastic debris and convert it into furniture.  Read More

A laptop shell made from Paper PP Alloy, a new composite material made from recycled paper...

It’s possible that your next laptop computer could contain parts of your present-day notebook ... not your notebook computer, mind you, but your actual notebook. At least, it will if China's PEGA Design and Engineering has anything to say about it. The company’s new Paper PP Alloy, made from a combination of recycled paper and polypropylene, is intended for use in the shells of consumer electronic devices.  Read More

A newly-developed mathematical model could make the development of new plastics much more ...

When it comes to the development of new plastics, two things have generally happened – a plastic is created and then a use is found for it, or a long trial-and-error process is undertaken in order to create a plastic with specific qualities. In a move that has been described as “comparable to cracking a plastics DNA,” however, scientists at the University of Leeds and Durham University have created a mathematical model that should allow specialty plastics to be created much more quickly and efficiently.  Read More

Scientists have used waste chicken feathers to create a strong, water-resistant thermopola...

At last week’s 241st National Meeting & Exposition of the American Chemical Society, a number of institutions presented their research into possible new sources of eco-friendly bioplastic, including everything from fruit fiber to bone meal. On the final day of the event, one other idea was put forward – bioplastic made from waste chicken feathers. While this particular source material has been tried only semi-successfully in the past, the researchers claim that this time, the chicken plastic should take flight.  Read More

A research team from Brazil has developed a new form of plant fiber-based plastic that is ...

A research team from Brazil has developed a new form of plant fiber-based plastic that is claimed to be stronger, lighter, and more eco-friendly than plastics currently in use. Team leader Alcides Leão says that some of the so-called nano-cellulose fibers can be almost as stiff as Kevlar, but that the plastic differs from many in widespread use because the source material – such as pineapple and banana – is completely renewable. The researchers say that current production efforts are centered around the manufacture of automotive plastics, but future development could see steel and aluminum being replaced.  Read More

Meat and bone meal (pictured above) has been used to create partially-biodegrable bioplast...

Creepy as it may sound, for decades one of the key ingredients in cattle feed was meat and bone meal (MBM), made from by-products of – you guessed it – slaughtered cattle. Sheep, farmed deer, elk and bison were also unknowingly eating their own kind. With the onset of the Mad Cow Disease scare in 1997, the U.S. and other countries banned the use of MBM-containing feeds, as it was believed that the disease could spread via the ingestion of infected animals' body parts. That ban has resulted in large quantities of MBM simply ending up in landfills. Now, however, scientists are suggesting that it could be used to make green(ish) plastics.  Read More

Researchers have developed a method of laser-welding transparent pieces of plastic to one ...

Laser welding of plastic is quick, precise, and generates little waste, but it does have its limitations. The process involves shining a laser beam through the edge of an upper sheet of plastic and onto the joining edge of a lower sheet, which has had soot particles mixed into it to absorb the radiation – this means that manufacturers are almost always limited to joining transparent plastic to black plastic. Researchers from Germany’s Fraunhofer Institute for Laser Technology, however, have recently developed a method for welding transparent plastics to one another.  Read More

Given that German scientists have already developed packaging film that kills food-inhabiting bacteria, it only makes sense that Scottish scientists should be developing the next step in the process – food packaging that changes color when the food is going bad. The “intelligent plastic” film, which is being created at Glasgow’s University of Strathclyde, is intended to take the guesswork out of whether or not the food packaged within it is still safe to eat.  Read More

Materials that can repair themselves are generally a good thing, as they increase the lifespan of products created from them, and reduce the need for maintenance. Biorenewable polymers are also pretty likable, as they reduce or even eliminate the need for petroleum products in plastic production, replacing them with plant-derived substances. Michael Kessler, an Iowa State University associate professor of materials science and engineering, and an associate of the U.S. Department of Energy’s Ames Laboratory, is now attempting to combine the two.  Read More
