It's snowing plastic

New technique detects minute particles of plastics in snow, rain and even soil

22-Mar-2021

The snow may be melting, but it is leaving pollution behind in the form of micro- and nano-plastics according to a McGill study that was recently published in Environmental Pollution. The pollution is largely due to the relatively soluble plastics found in antifreeze products (polyethylene ...

The expanding possibilities of bio-based polymers

Researchers present a new route to prepare biobased polyesters with tuneable properties

04-Mar-2021

Finding innovative and sustainable solutions to our material needs is one of the core objectives of green chemistry. The myriad plastics that envelop our daily life - from mattresses to food and cars - are mostly made from oil-based monomers which are the building blocks of polymers. Therefore, ...

Fabricating the future with a new environment friendly method of polymerization

Insights into a novel environment friendly method of polymerization involving non-metallic organocatalysts opens doors to efficient polymeric products

01-Mar-2021

Many materials in the modern world--from the plastics that dominate it to the electronic chips that drive it--are constructed of polymers. Given their ubiquity and the evolving requirements of our world, finding better and more efficient methods of making them is an ongoing research concern. In ...

More sustainable recycling of plastics

Chemists have developed a method for more sustainable recycling of polyethylene-like plastics

22-Feb-2021

Plastics belong to the most widely used materials, and they are vital components of all modern technologies. So far, it has been possible to recycle these valuable materials only to a limited extent. In order to offer novel solutions, chemists of Professor Stefan Mecking’s group at the University ...

Bioplastics in the sustainability dilemma

Scientists investigate the factors affecting the global land use impacts and CO2 emissions of plant-based plastics

09-Feb-2021

Plastics made from crops such as maize or sugarcane instead of fossil fuels are generally considered sustainable. One reason is that plants bind CO2, which compensates for the carbon released into the atmosphere when plastics are disposed. However, there is a catch: With increasing demand for raw ...

A mild way to upcycle plastics used in bottles into fuel and other high-value products

29-Jan-2021

Plastic is ubiquitous in people's lives. Yet, when plastic-containing items have fulfilled their missions, only a small amount is recycled into new products, which are often of lower quality compared to the original material. And, transforming this waste into high-value chemicals requires ...

New route to chemically recyclable plastics

"This is about understanding really cool chemistry and trying to do something good with it"

27-Jan-2021

As the planet's burden of rubber and plastic trash rises unabated, scientists increasingly look to the promise of closed-loop recycling to reduce waste. A team of researchers at Princeton's Department of Chemistry announces the discovery of a new polybutadiene molecule - from a material known for ...

Eliminating microplastics in wastewater directly at the source

A research team has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source

22-Jan-2021

A research team from the Institut national de la recherche scientifique (INRS) has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source. The results of this research have been published in the Environmental Pollution journal. Wastewater can ...

New biodegradable polyurethane foams are developed from wheat straw

21-Jan-2021

Every year around 734 million tons of wheat straw are produced worldwide, a large amount of waste, which is cheap and has had no well-defined use until now. Recently, the RNM-271 Chemical Engineering and FQM-383 NANOVAL Organic Chemistry research groups at the University of Córdoba have been able ...
