Folding boxes are considered sustainable packaging solutions for numerous everyday products – whether breakfast cereals, electronics, medicines, or perfumes. Made from paper and cardboard, folding boxes are resource-efficient in production, biodegradable, and easily recyclable. However, environmentally friendly adhesives are still lacking for completely sustainable manufacturing. Researchers at Fraunhofer Institute for Applied Polymer Research IAP are developing and testing bio-based adhesives for the industrial production of folding boxes in the project Sustainable Gluing With Renewable Adhesives (SUGRA).

The odor of recycled plastics is a major challenge for their recycling and requires customized solutions. Recyclates can have undesirable odors that come from various sources, such as microbiological degradation or residues of previous contents. This is precisely where the Fraunhofer CCPE compact on December 5, 2024, on the topic of “Emission and odor optimization in plastics and recyclates” comes in. Prof. Andrea Büttner, Board of Management Member of the Fraunhofer CCPE and Director of the Fraunhofer Institute for Process Engineering and Packaging IVV, provides initial answers to key questions in this interview.

Hardly any other chemical substance can compete with PFAS, due to their unique properties. That explains why it is so hard to find a replacement for these toxic “forever chemicals”, which accumulate in the environment and do not break down over time. A team at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM has succeeded in developing solutions that hold great promise of targeted substitution for PFAS in fields including medical engineering.

Production of fine chemicals such as those used in pharmaceuticals is typically complex and laborious. An interdisciplinary team of Fraunhofer researchers worked together across different projects to devise a method modeled on a cascade, in which multiple successive stages of synthesis proceed without interruption. This is made possible through the use of novel catalysts in specially adjusted flow-through reactors. The new method makes the process of manufacturing drugs more efficient and conserves energy. In this way, the modular technology platform supports the production of pharmaceuticals in Germany as an industrial location.

In order to achieve its goal of decarbonizing raw material flows, the chemical industries must cover their carbon requirements from sustainable sources. The direct capture of CO₂ from the air has hardly played a role so far – mainly due to the high investment and operating costs. The partners in the "Air2Chem" project want to change this: They are developing an integrated process that combines the "Direct Air Capture" process with electrolytic conversion of the green carbonate-containing absorber solution into platform raw materials for the chemical industries.

Flexible, disposable plastic films used in shopping or garbage bags are made mainly from petroleum-based low-density polyethylene (LDPE). These films, however, come with a large carbon footprint and contribute to environmental pollution. A team from the Fraunhofer Institute for Applied Polymer Research IAP has now developed a flexible and recyclable plastic film material based on polylactide (PLA) bioplastic and paved the way for its commercialization. For their efforts, they will receive the Joseph von Fraunhofer Prize for 2024.

Due to their stability and resistance to water and grease, PFAS chemicals (short for per- and polyfluoroalkyl substances) are used in a wide range industries, but they are harmful to health and the environment. Membranes containing PFAS are used in many semiconductor manufacturing processes, for example. Researchers from the Fraunhofer Institute for Applied Polymer Research IAP have now developed a sustainable alternative in the form of an innovative, PFAS-free membrane. The chemically stable, highly permeable polymer membrane has a pore diameter of approx. seven nanometers and enables filtration of the smallest particulate contaminants. The membrane can be customized to meet specific needs, which makes it easy to integrate the new process into existing systems.

Plastics made of polycarbonate are sought-after materials in industrial applications thanks to their versatility and high quality. However, recycling of plastic waste is still running up against limits these days, as mechanical recycling methods do not produce adequate qualities of recycled material for all applications. Together with chemical company Covestro Deutschland AG, Fraunhofer researchers have now developed a method that makes it possible to reclaim the substances originally used to make the polycarbonates. In catalytic pyrolysis, a controlled process of heating in an oxygen-free environment, plastic waste breaks down into its components. Manufacturers can then use the raw materials to produce new plastics.

Synthetic rubber is indispensable today, especially for car tires and technical rubber goods. Until now, the raw materials for its production have largely been obtained from fossil sources. Under the leadership of the Fraunhofer Institute for Applied Polymer Research IAP, four Fraunhofer Institutes are now developing alternative, bio-based raw material sources for synthetic rubber, which will enable completely new types of rubber for car tires. The three-year project is being funded by Fraunhofer with 3.25 million euros and starts in April 2024.

Metals can be processed into wires by cold forming - an extremely complex process. However, the lubricants needed for this often do not meet the requirements of the end processors. As part of the KMU-innovativ project "Polyschmierung", five partners from industry and research have developed a new class of polymer lubricants that make the process significantly more environmentally friendly and economical. They are already being used successfully by industry. The project was funded with around 680,000 euros by the Federal Ministry of Education and Research (BMBF) via the Project Management Agency Karlsruhe (PTKA).

Adhesives are almost always based on fossil raw materials such as petroleum. Researchers at Fraunhofer have recently developed a process that allows to utilize keratin for this purpose. This highly versatile protein compound can be found, for instance, in chicken feathers. Not only can it be used to manufacture a host of different adhesives for a variety of applications, but the processes and end products are also sustainable and follow the basic principles underlying a bio-inspired circular economy. The project, developed together with Henkel AG & Co. KGaA, addresses a billion-dollar market.
