From the Sector

Using bio-based and bio-degradable, recyclable insulation textiles to sustainably insulate heat and reduce energy consumption and the carbon footprint - the Aachen-based start-up SA-Dynamics has developed a solution for this dream of many building owners together with industrial partners. SA-Dynamics won the second Innovation Award in the "New Technologies on Sustainability & Recycling" category at the leading textile trade fairs Techtextil and Texprocess for this development.

The bio-based recyclable insulation textiles consist of 100 percent bio-based aerogel-fibres. They contain up to 90 percent air, trapped in the nano-pore system of the aerogel-fibres. The bio-based raw material is sustainably sourced and certified. The insulation textiles made from bio-based aerogel fibres are said to insulate the same or even better than synthetic insulating materials of fossil origin like PET, PE or PP and mineral or stone wool.

"By using bio-based aerogels, we are doing away with fossil-based materials and doing something for the environment and climate," explains Maximilian Mohr, Chief Technical Officer (CTO) at SA-Dynamics. "We are thus meeting the regulatory measures of the EU and the governments of many countries for more climate and environmental protection. By using bio-based, recyclable aerogels, we can revolutionise the world of construction.“

The Aachen-based start-up SA-Dynamics is made up of researchers from the Institut für Textiltechnik (ITA) and the Institute of Industrial Furnace Construction and Heat Engineering (IOB) at RWTH Aachen University.

The bio-based aerogel fibres originate from the LIGHT LINING research project of the BIOTEXFUTURE innovation area. The LIGHT LINING research project focussed on sports and outdoor textiles. The research results are transferable to the construction sector.

The Techtextil and Texprocess Innovation Awards ceremony will take place on 23 April 2024 at 12.30 pm in Hall 9.0 in Frankfurt/Main, Germany.

Prof. Manfred Renner and Prof. Christian Doetsch will take joint leadership of the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT from August 2022. As renowned scientists, they have most recently shaped the direction of the institute as heads of the Products division and Energy division respectively, and will now follow in the footsteps of Prof. Eckhard Weidner, who has entered retirement.

This is the first time in its history that Fraunhofer UMSICHT is led by two directors. Both institute directors began their professional careers at the institute and from August they will have a joint hand in its future.

Prof. Manfred Renner holds a doctorate in mechanical engineering, specializing in process engineering and business development. Since 2006, he has held various roles at Fraunhofer UMSICHT, most recently heading up the Products division and overseeing its 126 employees and its budget of 14.8 million euros. He has set international standards through his award-winning research into a free of water tanning leather tanning process that uses compressed carbon dioxide. With the development of innovative aerogel-based insulation materials for building facades, he has made a significant contribution to environmentally friendly, circular applications in the construction industry and initiated a number of industrial projects. One of the notable technological breakthroughs made by his team was the development of a new type of fire-resistant glass, which can withstand even the most extreme heat. This won his development team the Joseph von Fraunhofer Prize in October 2020.

Alongside becoming institute director, Prof. Renner will also take over the leadership of the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE in August 2022. In this role, he will represent the Fraunhofer-Gesellschaft on a national and international level with regard to the transformation of industry and society to a circular economy. In addition, he will start his professorship in Responsible Process Engineering at the Faculty of Mechanical Engineering of the Ruhr-Universität Bochum. Over the course of his professorship, he will shape the systemic development of the circular economy at a corporate, regional and European level.

Prof. Christian Doetsch has worked in energy research for more than 25 years, spending most of this time at Fraunhofer UMSICHT. As head of the Energy division, he managed a team of around 145 employees and was responsible for a budget of approximately 10.4 million euros. His technological focal points are energy storage, Power-to-X technologies including hydrogen electrolysis and chemical conversion, catalysts, and energy system modeling and optimization. His overarching aim is the integration of renewable energies into a cross-sectoral, resilient energy system.

In 2015, Doetsch co-founded the award-winning start-up Volterion GmbH & Co. KG, which develops redox flow batteries. He attained high visibility on a global scale by redesigning stacks, one of the main components of redox flow batteries, an achievement for which he, his team and Volterion representatives were awarded the Joseph von Fraunhofer Prize in May 2021. The energy expert also acts as deputy spokesperson for the Fraunhofer Energy Alliance and task manager for the energy storage group at the International Energy Agency (IEA). He also co-founded the “Open District Hub e. V.,” an association that promotes the energy transition in the sector by means of energy systems integration.

Since January 2020, he has been Professor of Cross Energy Systems at the Faculty of Mechanical Engineering of the Ruhr-Universität Bochum. In this role, he conducts research into ecological evaluation and resilience of cross-sectoral energy systems.

• Second Session of the International Conference on Cellulose Fibres 2022

Cellulose fibers are a true material miracle as they offer a steadily expanding, broad range of applications. Meanwhile markets are driven by technological developments and policy frameworks, especially bans and restrictions on plastics, as well as an increasing number of sustainability requirements. The  presentations will provide valuable information on the various use-opportunities for cellulosic fibers through a policy overview, a special session on sustainability, recycling and alternative feedstocks, as well as the latest developments in pulp, cellulosic fibers and yarns. In addition, examples of non-wovens, packaging and composites will offer a look beyond the horizon of conventional application fields.

The second session of the conference: "New Opportunities for Cellulose Fibres in Replacing Plastics", will focus on questions such as: "What is the impact of the ban on plastics on single-use products?" and "What are the latest regulatory issues and policy opportunities for cellulose fibres?".  This section presents new opportunities for replacing fossil-based insulating materials with cellulose-based technologies that can be used for a variety of applications, from aerospace to mobility, as well as in construction.
