Metal processing with lasers and plasma releases many different pollutants into the ambient air. Fraunhofer IWS, together with partners, has developed a filter system that efficiently removes these substances from the air.

Industrial production causes environmental damage by polluting soil, air and water – raw materials and energy are consumed, chemicals are used, waste and emissions are generated. At Fraunhofer IWS we support the change from a linear to a circular economic system combining economy with ecology and strengthening the competitiveness of companies. Functional surfaces are a prime example of what we are able to achieve for and with our customers. They help to increase the service life of components or to dispense with the use of environmentally harmful media. We have developed, for example, anti-fouling coatings for offshore applications and self-cleaning functional surfaces by means of laser-based processes.

The acceptance and future prospects of modern electric drive concepts also depend on the possibility of recycling used batteries in a resource-conserving and environmentally compatible way. We close loops in electromobility, for example, through emission analyses and filter solutions for environmentally compatible recycling processes. We also provide gas and particle analyses to detect and analyze pollutants in the air. With appropriate extraction and filter solutions, we help to create safer workplaces in production.

Separated ultra capacitors for material.

Numerous industrial companies and three Fraunhofer institutes (IKTS, IWS, IVI) are collaborating in the BMWi-funded project "ReCycle*" to research technologies along the value added chain of reprocessing lithium-ion batteries and supercap storage devices. All process steps – from collection, deep discharge, disassembly, crushing, fractionation to recovery of relevant raw materials – are specifically taken into account in the consortium. We focus on the conceptual design of processes and plants and on the feasibility demonstration on a small scale.

In this context, we are responsible for the detection of harmful gas and particle emissions during mechanical pulping - with various lithium-ion batteries and supercaps being investigated. Together with industrial partners, a filter prototype is developed and tested in the process under real conditions. The participation of the companies ensures that the research results will be transferred directly into application, thus making an important contribution to compliance with emission limits.

The »ReCycle« project is funded by the Federal Ministry for Economic Affairs and Energy (FKZ: 03ETE031K).
