Revamped plastics recycling chain

Today’s waste, tomorrow’s valuable resource

06-Mar-2024 - These days, the majority of consumable and everyday items are made from petroleum-based plastic. In Germany alone, some six million tons of plastic waste are generated every year. Approximately half of this is mechanically recycled into new materials; the rest is used for energy recovery. ...

Inspired by the gecko: Better adhesion properties of plastics through combined micro- and nanostructures

Structured surface improves adhesion, wettability, optical reflection, hydrophobicity and recyclability.

27-Feb-2024 - With a patented process for micro-nano-structuring, the Fraunhofer Institute for Microstructure of Materials and Systems IMWS in Halle (Saale) has achieved significant improvements in the adhesion properties of polymers. The process, in which structured surfaces are produced by hot imprinting or ...

Non-toxic plasticisers for use in elastomers and thermoplastics

Bio-based plasticizers from Central Germany

08-Dec-2023 - The Fraunhofer Institute for Microstructure of Materials and Systems IMWS is working with partners to develop a marketable, completely bio-based and non-toxic plasticizer for use in elastomers and thermoplastics. Using rapeseed oil as a starting product, more sustainable solutions for tires and ...

How cleaning agents can damage photovoltaic modules

21-Sep-2023 - In order for the sunlight to be optimally utilized by photovoltaic modules, they must be cleaned regularly. Chemical cleaning additives are intended to enhance the cleaning effect. However, these can bring with them a high potential for damage. The Fraunhofer Center for Silicon Photovoltaics CSP ...

Nanocoating prevents greasy smears

Anti-fingerprint surfaces

05-Jul-2019 - Not only are greasy fingerprints on shiny stainless steel surfaces unattractive, they also attack the surface in question. A new nanocoating being developed by Fraunhofer researchers will in the future prevent the annoying smudges that result from fingers touching stainless steel surfaces. The ...

Eco-friendly formulations based on vegetable oils

Solvent-free adhesives

10-May-2019 - There is an increasing demand for green products, but for them to be genuinely sustainable, manufacturers must also use adhesives and paints that are made of bio-based feedstocks. Advanced materials developed in Fraunhofer labs point the way forward. Demand for organic products is booming. ...
