Bio-based polyesters for challenging long-term applications

Current bio-based plastics are often only suitable for short-lived applications, such as packaging, because they have inadequate long-term properties. The new project “Bio-based polyesters for challenging long-term applications” from the Fraunhofer Institute for Structural Durability and System Reliability LBF aims to improve the long-term properties of bioplastics through targeted additivation in order to enable their use in technical applications. To do this, the researchers are looking for companies along the value chain that would also like to substitute petro-based plastics with bio-based solutions in long-lasting products.

In the planned project, bio-based materials will be optimized through targeted additivation to be comparable to petrochemical plastics. In numerous projects in recent years, researchers from the Fraunhofer Institute for Structural Durability and System Reliability LBF have conducted research in the field of plastic additives and can improve the long-term properties of plastics made from both fossil and renewable raw materials. The aim of the project is to replace petrochemical-based technical plastics in a sustainable way based on the knowledge gained so far in material optimization and to implement this along the entire value chain.

Minimal changes in the manufacturing process

The project addresses the challenges of the long-term properties of bioplastics. In a comprehensive literature review, existing data on long-term stability and the stabilizers used are first compiled. Together with the project partners, a specification sheet will be created that defines the material properties to be achieved. Market-available bioplastics and additives will be identified and tested for their properties. The modification of the bioplastics will be carried out by developing new formulations on a pilot plant scale. The aim is to enable material substitution with minimal changes to existing processing methods.

The Fraunhofer scientists are looking for partners from companies along the value chain, starting with manufacturers of plastics and additives, and including companies that want to substitute individual components in their designs, with a particular focus on developers and producers of finished components.

The use of novel additive systems should extend the life cycle of bio-based polyesters.

Securing competitive advantages together: sustainable, sophisticated plastic products

OEMs and manufacturers of plastic components in the construction, automotive, sports and leisure, electrical and electronics, and household appliance sectors who want to replace petrochemical-based plastics with bio-based solutions will gain sufficient knowledge to optimize their own research and development in a targeted and individualized way by participating in the new project “Bio-based polyesters for demanding long-term applications”. They will benefit directly from the latest findings, thereby securing competitive advantages. Raw material and additive manufacturers can expand their existing product portfolio with new applications, and compounders can prepare for future challenges in the use of bioplastics.

High-performance elastomers and plasma polymer coatings to replace fluoropolymers in technical applications: new Fraunhofer project

Users of poly- and perfluorinated alkyl compounds (PFAS), also known as "forever chemicals", are under pressure due to regulatory proposals from the European Chemicals Agency (ECHA). This also affects the use of fluoroelastomers, whose economic significance is enormous. Fraunhofer experts initiated the "HATE-Fluor" project at the beginning of February. Together, they want to develop high-performance elastomer compounds to replace fluoropolymers in certain technical applications.

New DIN SPEC assesses environmental impact of textile fragments in soil

Textile products made from synthetic fibres, finished fabrics or dyed materials release fibre fragments into the environment at every stage of their life cycle. With the new DIN SPEC 19296, Hohenstein has developed a standardised testing method to analyse how these fragments behave in soil under natural conditions. Until now, little was known about their environmental behaviour or potential ecological effects once released.

Solid Air Dynamics wins second place at RWTH Innovation Award

On 30 January, RWTH spin-off Solid Air Dynamics was awarded second place in the RWTH Innovation Awards for its research in the field of aerogel fibres. Manufactured from renewable raw materials, aerogel fibres offer outstanding thermal insulation, are extremely lightweight and completely biodegradable, and can consist of over 90 per cent air.

Testing and research laboratory ensures safe and more sustainable products worldwide

For 80 years, Hohenstein has stood for independent testing, scientific expertise and practical solutions. Today, the testing and research service provider supports manufacturers and brands worldwide in making textiles, hardlines and medical devices safe, more sustainable and market-ready – thereby building trust among consumers. With an international presence and interdisciplinary expertise, Hohenstein supports its customers from production through to market launch, helping them navigate an environment of growing regulatory and societal demands.

Award-winning research for sustainable carbon fibre cycles

Sustainable recycling of carbon fibres is possible through targeted electrochemical surface modification, which makes the sizing of carbon fibres resistant to solvolysis. ITA PhD student Sabina Dann was awarded the MSW Award from RWTH Aachen University for her master's thesis on this development. The award ceremony took place on 12 November 2025 in Aachen.

Circulose restarts commercial-scale production at Ortviken plant in Sundsvall

Circulose today announced the restart of its commercial-scale production plant at Ortviken in Sundsvall, Sweden, marking a significant step in scaling next-generation materials for the global fashion industry. The company plans to resume production of CIRCULOSE®, a recycled pulp made entirely from discarded cotton textiles, in the fourth quarter of 2026.

VIATT 2026 to debut German Pavilion, strengthening European participation alongside key Asian textile hubs

Vietnam’s textile and garment sector continues to be a major contributor to the country’s economic growth, with export revenues expected to reach USD 46 billion in 2025, a 5.6% increase from 2024 . From 26 – 28 February, the Vietnam International Trade Fair for Apparel, Textiles and Textile Technologies (VIATT) is set to contribute to economic growth opportunities by accelerating digital transformation and green transition across the entire textile value chain. The upcoming edition will respond to the rising demand for advanced technologies and sustainable materials with the introduction of the German Pavilion, alongside strong exhibitor participation from key Asian sectors, as well as several high-profile fringe events.

Sustainable, lightweight, and sound absorbing: Polyester-based front trunk solution for BEVs

As car manufacturers look to further reduce their carbon footprint, Autoneum has developed an innovative front trunk solution for battery electric vehicles (BEVs), made entirely from polyester-based textile. The Ultra-Silent Frunk offers significant weight reduction, improved acoustic and thermal insulation, and uses up to 70 percent recycled material, supporting sustainable and efficient vehicle design. Autoneum, global technology leader in acoustic and thermal management for vehicles, has already received orders for the new frunk from three major OEMs in Asia and Europe to be built in three BEV models. Series production for two BEVs has been underway in China and Germany since last year.
