Microplastics waste is a valuable resource – it is just in the wrong place

The negative image of plastic persists and is not getting any better in the face of the ongoing debate about microplastics which are basically everywhere. Plastic pollutes the environment. The globe is littered with huge quantities. We have to modify the production and utilisation of macroplastics as well as fundamentally rethink the way we dispose of them. ‘Out of sight, out of mind’ mentality must become a thing of the past.

Recycling of the future – marked plastic as a circular product

Plastics are harmful to the climate and human health both during manufacture and combustion and they also clutter our planet with garbage. Recycling is therefore a key issue, but it is not efficient. Polysecure has developed a process for permanently marking individual plastics that enables them to be separated efficiently and returned to a circular economy. This would counteract the vast amount of (micro) plastics and reduce CO₂ emissions.

Coffee capsules: wood instead of aluminium

In Germany alone, around three billion disposable coffee capsules made of aluminium and plastic are sold every year. This creates a gigantic waste problem, as only a small proportion of the capsules can be recycled. Fully compostable wooden coffee capsules might be a solution to this problem. The capsules have been developed by a start-up company called rezemo, which also has other biobased packaging solutions in the pipeline.

Natural substance with herbicide potential - 10/12/2020

The same but different: What makes sugar 7Sdh a better herbicide?

The sugar 7-deoxy-sedoheptulose (7dSh) is produced by cyanobacteria and inhibits the same metabolic pathway as the broad-spectrum herbicide glyphosate, thus making it an excellent herbicide candidate. Despite this amazing similarity, the microbiologist who discovered 7dSh, Prof. Dr. Karl Forchhammer, believes that this sugar has clear ecological advantages over glyphosate.

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules. The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing. In the last few years Fraunhofer IGB and partners have developed technology to provide fibers with the desired properties using biotechnological processes and chitosan.
