Green catalysts with Earth-abundant metals accelerate production of bio-based plastic

How crystalline structure can affect the performance of MnO2 catalysts

10-Jan-2019

Scientists at Tokyo Institute of Technology (Tokyo Tech) have developed and analyzed a novel catalyst for the oxidation of 5-hydroxymethyl furfural, which is crucial for generating new raw materials that replace the classic non-renewable ones used for making many plastics. It should be no ...

Testing the first biodegradable straws

23-Aug-2018

A research team that includes partners from the University of Georgia New Materials Institute and the RWDC Environmental Stewardship Foundation will develop a fully biodegradable plastic straw thanks to an award from Singapore's Temasek Foundation Ecosperity. The $719,000 award represents the top ...

Soil bugs munch on plastics

27-Jul-2018

Thin mulch films made of polyethylene are used in agriculture in numerous countries, where they cause extensive soil contamination. Researchers at ETH Zurich and Eawag have now identified an alternative: films made of the polymer PBAT biodegrade in soils. Our world is drowning in a flood of ...

Photocatalyst system for plastics production

Properties of recyclable plastics can be defined by the wavelength

05-Jul-2018

A research team from Berlin has developed a novel catalyst system, which enables the regulation of multiple polymerization processes to produce biodegradable plastics solely by illumination with light of different colors. The properties of a polymeric material are highly dependent on factors, ...

A path to sustainable and biodegradable polyesters

04-Jun-2018

There's a good chance you've touched something made out of the polyolefin polymer today. It's often used in polyethylene products like plastic bags or polypropylene products like diapers. As useful as polyolefins are in society, they continue to multiply as trash in the environment. Scientists ...

A polymer that puts plastic on a better path toward recyclability

27-Apr-2018

Researchers have developed a family of synthetic polymers that can be repeatedly recycled, an important feat because current efforts to recycle plastic are so limited. Globally, the production of plastic has increased to the point where output is expected to exceed 500 million metric tons by ...

Scientific advances can make it easier to recycle plastics

21-Nov-2017

Most of the 150 million tons of plastics produced around the world every year end up in landfills, the oceans and elsewhere. Less than 9 percent of plastics are recycled in the United States, rising to about 30 percent in Europe. That's a $176 billion problem, the potential energy savings ...

3-D-printed biomaterials that degrade on demand

12-Sep-2017

Brown University engineers have demonstrated a technique for making 3-D-printed biomaterials that can degrade on demand, which can be useful in making intricately patterned microfluidic devices or in making cell cultures than can change dynamically during experiments. "It's a bit like Legos," ...

A sweeter way to make green products

12-Sep-2017

The shampoo you washed your hair with this morning. The balloons for the party. Refrigerators and sunglasses, medicine and mosquito repellent, guitar strings and fishing lures. These -- and thousands of other products we use every day -- contain chemicals made from petroleum. But researchers at ...

Technique could aid mass production of biodegradable plastic

01-Sep-2017

Introducing a simple step to the production of plant-derived, biodegradable plastic could improve its properties while overcoming obstacles to manufacturing it commercially, says new research from the University of Nebraska-Lincoln and Jiangnan University. That step? Bringing the heat Nebraska's ...
