Enzyme that breaks down PET plastic: Leipzig scientists increase efficiency
18/05/2023
A research team at the University of Leipzig has further improved the functioning of an enzyme that can degrade PET plastic. Through computer simulations and experiments, they were able to rationally improve the enzyme and are now working on developing the third generation of the enzyme.
Chemists redesign biological PHAs, 'dream' biodegradable plastics
11/05/2023
Colorado State University polymer chemists have created a synthetic Polyhydroxyalkanoates (PHA) platform. These newly designed PHAs are mechanically tough, even outperforming the two most common commodity plastics. Among other things, this is intended to address the thermal instability of conventional PHAs and is a major step toward sustainability.
Better recycling of plastic packaging: New process extracts fragrances
04/05/2023
Researchers at the Fraunhofer Institute have developed an environmentally friendly process to remove fragrances from plastic packaging. The process is based on pressurized water extraction and removes the fragrance limonene from HDPE packaging. By evaluating the data using machine learning methods, it was possible to optimize the extraction parameters.
First comparative study on automated analysis methods of large data sets in microplastics research
27/04/2023
The lack of standardized analytical procedures for microplastic data has led to significant deviations, especially for small particles with high hazard potential. Researchers from the University of Bayreuth and the Alfred Wegener Institute have compared two automated analysis procedures and called for standardization to improve the comparability of data.
Solar-powered system converts plastic and greenhouse gases into sustainable fuels
13/04/2023
Researchers at the University of Cambridge have developed a system that can convert plastic waste and greenhouse gases into sustainable fuels and other valuable products – using energy from the sun alone. In the system, two waste streams are simultaneously converted into two chemical products.
A wholly sustainable plastics economy is feasible
13/04/2023
In a study under the leadership of the ETH Zurich, the scientists point out that plastic products must be better aligned with the circular economy in future. The study finds that circular plastics are feasible within planetary boundaries. This would require at least 74 percent of the plastic to be recycled.
Researchers use light to convert abundant lignin into plastic that can be continually recycled
05/04/2023
Boston College chemists have developed an approach that uses light to transform lignin into sustainable plastics. The findings advance a potential strategy for the waste-free system of polymer manufacture and re-use known as the circular plastic economy.
Degradation of Plastic Waste using newly Developed Biocatalysts
13/03/2023
A research team from the University of Greifswald, together with scientists from Covestro AG, has identified enzymes capable of degrading polyurethanes and polyvinyl alcohol. The research helps to establish a sustainable and environmentally-friendly process to recycle these polymers.
Automated simulation software creates a world map of polymer properties
14/02/2023
"Materials informatics (MI), a new branch of materials research that combines materials data with data science, is gaining traction," said co-corresponding author Yoshihiro Hayashi, assistant professor, Institute of Statistical Mathematics in the Research Organization of Information and Science (ROIS).
Bio-based flame retardants for bioplastics in electrical engineering and electronics
06/02/2023
Fraunhofer researchers, in collab with industrial partners, have achieved initial success in the development of bio-based flame retardants in bioplastics. In the future, it could therefore be possible to utilize plastics in electronics and electrical engineering that consist of 100% bio-based materials. Processing was tested by means of compounding, injection molding and additive manufacturing.
