Protective ship coatings as an underestimated source of microplastic pollution
Shipping traffic can be a major source of microplastics, especially out in the open ocean. In a new study, a team of environmental geochemists from the University of Oldenburg (Germany) for the first time provides an overview of microplastics mass distribution in the North Sea. The scientists found that most of the plastic particles in water samples taken in the south-eastern North Sea originate from binders used in marine paints. Their hypothesis is that ships leave a kind of 'skid mark' in the water. (2021-02-23)

Researchers grow artificial hairs with clever physics trick
Things just got hairy at Princeton. Researchers found they could coat a liquid elastic on the outside of a disc and spin it to form useful, complex patterns. When spun just right, tiny spindles rise from the material as it cures. The spindles grow as the disc accelerates, forming a soft solid that resembles hairs. Published in PNAS Feb. 22 (2021-02-22)

Plastic recycling results in rare metals being found in children's toys and food packaging

More sustainable recycling of plastics
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 of Konstanz developed a more sustainable method for chemically recycling polyethylene-like plastics. The researchers use ''breaking-points'' on a molecular level to disassemble the plastic back to its molecular components. (2021-02-17)

Molecule from nature provides fully recyclable polymers
Plastics are among the most successful materials of modern times. However, they also create a huge waste problem.

A mild way to upcycle plastics used in bottles into fuel and other high-value products
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 substantial energy. Now, researchers reporting in ACS' JACS Au have combined a ruthenium-carbon catalyst and mild, lower-energy reaction conditions to convert plastics used in bottles and other packaging into fuels and chemical feedstock.

Dramatic increase in microplastics in seagrass soil since the 1970s
Large-scale production of vegetables and fruit in Spain with intensive plastic consumption in its greenhouse industry is believed to have leaked microplastic contaminants since the 1970s into the surrounding Mediterranean seagrass beds. This is shown in a new study where researchers have succeeded in tracing plastic pollution since the 1930s and 1940s by analyzing seagrass sediments. (2021-01-25)

Cargo delivery by polymers
Degradable, bio-based polymers offer options for chemical recycling, and they can be a tool to store and release useful molecules. Scientists have developed a class of sugar-based polymers that are degradable through acid hydrolysis. The researchers also integrated ''cargo'' molecules in the polymer, which are designed to split off after polymer degradation. Degradable, cargo-bearing polymers are important for medical and sensor applications, says the study published in the journal Angewandte Chemie. (2021-01-22)

Upcycling: new catalytic process turns plastic bags into adhesives
Only a small percentage of plastic bags and other polyethylene packaging is recycled because only low-value products can be made from this waste. UC Berkeley chemists have created a catalytic process that preserves the desirable properties of polyethylene while adding another attribute - stickiness - that increases the value of the recycled product. The adhesive polyethylene could be used to coat wires and metal implants or bond plastic layers. Even latex paint sticks to it. (2020-12-17)
