27.09.2023In the world of additive manufacturing, innovations are constantly revolutionising the possibilities. Despite the progress, there is one major challenge: the need for support structures. They prevent material layers from sagging – but removing them after printing can have environmentally damaging consequences. In the AquaLoes project, the IKT is tackling this challenge.
01.09.2023Prof. Dr. Christopher Kuenneth at the University of Bayreuth, Germany, together with research partners in Atlanta, has developed a digital system that filters out those materials best suited for targeted applications from among some 100 million theoretically possible polymers. The system, called polyBERT, treats the chemical structure of polymers like a chemical language.
17.08.2023Researchers at the Fraunhofer Institute have developed a recycling process to recover used fiber composite material from pressure tanks and use it for new lightweight products. The process preserves over 90 percent of the materials' mechanical properties. This contributes to the sustainable production of thermoplastic fiber composite products.
17.08.2023ADAM could redefine plastics manufacturing. A big claim, but not without reason: Behind the acronym ADAM is a software called "Advanced Dimension Additive Manufacturing" that caused a real stir at K 2022. The impressive result of this software in action? A high-performance screw extruder controlled by an agile jointed-arm robot.
25.07.2023The future of circular economy in the plastics industry is a complex mixture of mechanical and chemical recycling. Prof. Dr. Manfred Renner, Director of the Fraunhofer Institute for Environmental, Safety and Energy Technology (UMSICHT), describes these technologies as indispensable components of the life cycle of plastics.
08.06.2023A Collaboration project involving BASF, Krones, SÜDPACK, and TOMRA gives proof of concept for closed recycling loop for PET-based multi-layer packaging.
26.05.2023At Covestro's Wind Technology Center, research is being conducted into making wind technology more efficient. To do this, a close look is taken at wind turbines – where are opportunities to use special materials that drive renewable energy? The big goal behind it: Climate neutrality and a circular economy.
22.05.2023Plastics contribute to climate protection. As fibre-reinforced plastics for wind turbines or films for solar cells, they already play an important role in power generation from renewable energies. But the conventional solutions are not equally suitable for every area of application. This is where a new type of material comes into play that was developed at Saarland University.
13.04.2023Researchers 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.

27.01.2023Recycled plastics are often less efficient than new plastics. But they can be upgraded - namely by using fibre composites. In turn, they make the plastics difficult to recycle. The All-Polymer project shows how both are possible: high-performance materials and a closed cycle.
26.12.2022In a project called "Manufhaptics", researchers at Empa, together with EPFL and ETH Zurich, want to develop a VR glove that will make virtual worlds tangible. The VR glove is to be created using a 3D printing process and will have three different actuators.
