Process converts polyethylene bags, plastics to polymer building blocks
Catalysts disassemble polymer while adding ethylene, producing propylene, the building blocks of polypropylene
03-Oct-2022
Polyethylene plastics — in particular, the ubiquitous plastic bag that blights the landscape — are notoriously hard to recycle. They’re sturdy and difficult to break down, and if they’re recycled at all, they’re melted into a polymer stew useful mostly for decking and other low-value ...
Plastics of the future will live many past lives, thanks to chemical recycling
One day in the not-too-distant future, the plastics in our satellites, cars and electronics may all be living their second, 25th or 250th lives
28-Sep-2022
New research from the University of Colorado Boulder, published in Nature Chemistry, details how a class of durable plastics widely used in the aerospace and microelectronics industries can be chemically broken down into their most basic building blocks and then formed once again into the same ...
New upcycling system for commercial polyesters
Using commonly available materials and a simple mixing and heating process, polyesters can be transformed into highly recyclable, high-value materials
28-Sep-2022
While plastics or synthetic polymers have many useful properties, their mismanagement has resulted in widespread pollution that chokes up our ecosystems. As a solution to this, many synthetic polymers are sent for reprocessing and recycling; polyethylene terephthalate (PET) is one of the most ...
A sea change for plastic pollution: new material biodegrades in ocean water
Marine microorganisms found to feast on new polyurethane materials used in a startup's sustainable shoes
26-Sep-2022
Plastics, now ubiquitous in the modern world, have become a rising threat to human and environmental health. Around the planet, evidence of plastic pollution stretches from grocery bags in the deep sea to microplastics in our food supplies and even in our blood. Seeking solutions to counteract ...
Economical PEF Production
Efficient titanium-based catalyst used to produce PEF, the biobased alternative to PET
30-Aug-2022
One possible replacement for drink containers made from PET is polyethylene furandicarboxylate (PEF), made from renewable resources. However, the production of the raw material for PEF from biomass is still rather inefficient. A new titanium-based photocatalyst could be about to change this, ...
Wind turbine blades could someday be recycled into sweet treats
New turbine material by combining glass fibers with a plant-derived polymer and a synthetic one
25-Aug-2022
Wind power is an increasingly popular form of renewable energy. However, when it’s time to replace the huge turbine blades that convert wind into electricity, disposal is a problem. Now, scientists report a new composite resin suitable for making these behemoths that could later be recycled into ...
New method can remove dyes from wastewater
16-Aug-2022
North Carolina State University researchers have demonstrated that a synthetic polymer can remove certain dyes from water, and that the polymer can be recovered and reused. The findings offer a new potential method for cleaning wastewater after use by textiles, cosmetics or other ...
New method to promote biofilm formation and increase efficiency of biocatalysis
Researchers identified synthetic polymers that induce biofilm formation in E. coli, a bacterium commonly used in biocatalysis
04-Aug-2022
Birmingham scientists have revealed a new method to increase efficiency in biocatalysis, in a paper published in Materials Horizons. Biocatalysis uses enzymes, cells or microbes to catalyse chemical reactions, and is used in settings such as the food and chemical industries to make products that ...
WACKER Plans Expansion of Its Charleston Site and Prepares for Construction of Silicone Production Facilities
Construction of production facilities planned in phases over several years
01-Aug-2022
Wacker Chemie AG is preparing to build a new silicone production complex at its Charleston site in the US state of Tennessee. The Munich-based chemical group has already started a feasibility study. In a first step, it is planned to build production plants for high-consistency silicone rubber and ...
Final destination deep sea: microplastics impact ocean floor even more than assumed
The deep sea serves as the “oceans’ garbage dump” – and it is surprisingly dynamic when it comes to deposition
15-Jul-2022
Senckenberg researchers Serena Abel and Angelika Brandt, together with colleagues from the Alfred Wegener Institute – Helmholtz Centre for Polar and Marine Research (AWI) and Goethe University in Frankfurt, have investigated microplastic pollution in the Western Pacific Kuril-Kamchatka Trench. ...
