From the Sector

• Efficient heat supply of the future reduces environmentally harmful CO₂

The heating sector offers a variety of options for the energy turnaround. One of them is district heating. This is an efficient energy source that makes an important contribution to sustainability and climate protection, especially when used within heat and energy-intensive companies. The CHT Group for speciality chemicals has opted to utilise the district heating supplied by the Tübingen public utilities (swt) at its headquarters in Tübingen - and thus reduce CO2 and the use of fossil fuels. This also resulted in the district heating network of the municipal utilities being extended by an additional half kilometre.

Until recently, heating, hot water and various process steam applications within the CHT site in Bismarckstrasse, Tubingen were fed from a central steam generation plant fired by heating oil. Now three of four company buildings are connected to the swt district heating network and the process steam applications have been decentralised. The fourth building has already been equipped with a modern CHP system for many years. In the future, this building will be prepared for district heating. The conversion to district heating supply will be made as soon as the CHP plant has reached the end of its operating life. In order to connect the CHT headquarters to the district heating, the municipal utilities have extended their supply network by around 570 metres during a four-month construction period. The heat now flows through newly installed transfer stations where it is measured, regulated, transferred and finally fed into the buildings' heating circuits.

Dr. Bernhard Hettich, Chief Technical Officer of CHT Germany GmbH: "As a company CHT focuses on worldwide sustainability. This not only includes products but also the sustainable use of resources at the individual locations. At our headquarters in Tübingen, our efforts are directed towards reducing energy consumption and optimising it with regard to renewable energies. With this investment we will continue to reduce CO2 emissions and the consumption of fossil fuels for the energy we consume. As a Tübingen company, we are therefore pleased to be connected to the local district heating network and to be able to use its advantages for the benefit of our sustainability strategy".

High heat demand offers great savings potential
CHT's heat requirements are high as the three buildings already connected require around 1.3 million kilowatt hours of heat per year. With the fourth building included, the heat requirement is even 1.6 million kilowatt hours. With the conversion to district heating CHT saves about 152 tons of CO2 per year. An investment in the district heating connection is therefore an investment in the future, both from an ecological and economic point of view. CHT has invested 180,000 Euro in the district heating connection.

Sustainability and environmental responsibility are important developments for the current design of productions and products. In order to obtain a comprehensive evaluation of the potential of bio-based composites, the AZL, together with an industry consortium, is investigating the market potential, future applications and relevant technologies for bio-based composite materials. The 5-month market and technology study will start on October 22nd, 2020 and is open to interested companies. Companies such as REHAU, an Automotive Tier 1, Asahi Kasei, Johns Manville, Mahr Metering Systems and several material manufacturers are participating in the study.

Bio-plastics are well established in industry, especially in packaging applications. The market for biopolymers is expected to grow from USD 10.5 billion in 2020 to USD 27.9 billion in 2025. At the same time, bio-based raw materials, such as natural fibers, are available on the market in a cost-effective manner. Composites with wood or natural fiber content are also increasingly used in products.

Dr. Michael Emonts, Managing Partner of AZL: "Together with our partner companies we want to identify hidden business potential for composites with bio-based materials. To do so, we will reapply our established approach for market and technology studies: Based on a detailed market analysis, we will dive deep into the technological evaluation of technologies, applications and business cases.”

Based on a detailed market segmentation, AZL's technology experts analyze the various market segments in terms of their size, growth potential, relevant players and existing and future applications. For the identified applications, the participants in the study will receive detailed insight into the respective technical and legal requirements as well as an overview of value chains, processes and materials. In the following, the strengths and challenges of bio-composites compared to conventional materials are elaborated. The consortium will select the components with the highest potential, for which suitable production scenarios will be developed and analyzed in terms of costs in a business case analysis.

"We are participating in the AZL study to identify and evaluate new product areas with bio-materials. The technological analyses of the AZL studies have already helped us in the past to initiate new developments," says Dr. Steven Schmidt, Director Technology Platforms Materials at REHAU, explaining the motivation for working with the AZL and the industry consortium. "As one of the 50 Sustainability & Climate Leaders, we at REHAU are incorporating environmentally friendly materials into more and more products. Wherever the company is active - from the furniture and construction industries to the automotive industry - REHAU is already developing and manufacturing high-quality products from recycled raw materials. By 2025, REHAU plans to increase its recycling rate across the Group to significantly more than 15 percent and at the same time reduce CO2 emissions by at least 30 percent," adds Dr. Steven Schmidt.

Bio-composites will also be the topic of the upcoming Lightweight TechTalk by AZL on September 29, 2020. Experts from industry and academia will give technology and market insights on sustainability and recycling of composites in 6 presentations. Registration is free of charge at: https://azl-aachen-gmbh.de/termine/recycling-of-composites/.

The kick-off of the project will take place on October 22nd, 2020 in the form of a video conference. Further background information on the project can be found under the following link: https://azl-aachen-gmbh.de/wp-content/uploads/2020/09/2020-251_OP_Bio-Bases_Composites.pdf

• Die Tiny-House-Ausstellung »Wunderkammer der Bioökonomie« startet Ost-West-Tour im Wissenschaftsjahr.
• Besucher*innen lernen »Alte Bekannte« - vergessene Pflanzen - neu kennen.

In der interaktiven Ausstellung dreht sich alles um Pflanzen, Böden, Mikroben und Kulturen. Fraunhofer UMSICHT koordiniert das Projekt und entwickelte zusammen mit der Folkwang Universität der Künste die Workshops und Partizipationsformate. Ziel: Allen interessierten Menschen die vielseitigen Themen der Bioökonomie näherbringen und erlebbar machen.

Vom 26. bis zum 30. August 2020 startet die interaktiven Tiny-House-Ausstellung »Wunderkammer der Bioökonomie« ihre Deutschlandtour in Oppenheim (Rheinhessen). Mithilfe der »Alten Bekannte«, alltäglichen oder in Vergessenheit geratenen Dingen wie Sauerkraut, Wein oder Kompost, schlägt das im Wissenschaftsjahr 2020/21 geförderte Projekt eine Brücke zur Bioökonomie. Das komplexe Thema wird so anschaulich und in Workshops, Touren und Debatten erlebbar gemacht. Beim ersten Tourstopp stehen Pflanzen und deren Relevanz für die Bioökonomie im Mittelpunkt.

Seit jeher spielen Pflanzen für den Menschen eine besondere Rolle. Sie ernähren uns, versorgen uns mit Sauerstoff, wir bauen Möbel aus ihnen und verbrennen sie, um Wärme zu erzeugen. Pflanzen liefern uns Textilfasern und Biokunststoffe; sie sind für uns Stromquelle, Luftfilter und Schattenspender. Über Jahrtausende wurden diverse Pflanzen durch Zucht so verändert, dass wir sie vielfältig nutzen können. Doch der Klimawandel und der hohe Ressourcenverbrauch bringen neue Herausforderungen für die Pflanzenzucht mit sich. Können die »Alten Bekannten« einen Beitrag leisten, ihnen zu begegnen?

Alte und neue Pflanzenzuchtmethoden

Die »Wunderkammer der Bioökonomie« hält Antworten bereit und lässt Besucher*innen dabei selbst zu Entdecker*innen werden. In einem Workshop können mit altbekannten Methoden Zimmerpflanzen für zu Hause gezüchtet werden, die das Raumklima verbessern und anschließend auch mitgenommen werden dürfen. Expert*innen geben ihr Wissen über alte und neue Pflanzenzuchtmethoden weiter und debattieren anschließend mit dem Publikum, ob und wie diese zu einer nachhaltigen Gesellschaft beitragen können. Schließlich erwartet Interessierte eine Wanderung durch die Weinberge der Region Oppenheim, bei der sie erfahren, warum und wie Weinstöcke gezüchtet werden.

Nach dem einwöchigen Auftakt geht die Deutschlandtour des Projekts an drei weiteren Stationen weiter: Vom 22. bis zum 28. September dreht sich in Dresden alles um das Thema Boden, im Oktober werden in Thüringen Mikroorganismen unter die Lupe genommen und im November fragt die »Wunderkammer« in Dortmund, was Bioökonomie mit Kultur zu tun hat. Die Teilnahme an den Workshops ist kostenlos.

Wie können wir nachhaltiger leben, Ressourcen schonen und gleichzeitig unseren hohen Lebensstandard erhalten? Das Wissenschaftsjahr 2020|21 – Bioökonomie hält Antworten auf diese Frage bereit. Bürgerinnen und Bürger sind dazu eingeladen, im Dialog mit Wissenschaft und Forschung den Wandel hin zu nachhaltigen, biobasierten Produktions- und Konsumweisen zu diskutieren. In vielfältigen Formaten wird das Konzept der Bioökonomie mit all seinen Potenzialen und Herausforderungen erlebbar gemacht und aus unterschiedlichen Perspektiven beleuchtet. Die Wissenschaftsjahre sind eine Initiative des Bundesministeriums für Bildung und Forschung (BMBF) gemeinsam mit Wissenschaft im Dialog (WiD).

Non-contact precision spray technology enhances productivity, sustainability and process control

Baldwin Technology Company Inc. has announced that it will showcase the TexCoat G4 non-contact precision spray fabric finishing system at the Techtextil North America tradeshow, held from May 12 to 14, 2020, in Atlanta (booth #3048).

With extensive sustainability benefits, unprecedented tracking and process control, and industry 4.0 integration, the TexCoat G4 provides consistently high-quality fabric finishing, with no chemistry waste, as well as minimal water and energy consumption. 

Baldwin’s innovative non-contact spray technology eliminates chemistry dilution in wet-on-wet processes. The TexCoat G4 consistently and uniformly sprays chemistry across the fabric surface and applies it only where needed, on one or both sides of the fabric. Customers can expect no bath contamination during the finishing process, as well as minimal downtime during changeovers, which are made easy with recipe management that includes automated chemistry and coverage selection.

The TexCoat G4 also enhances sustainability by wasting no chemistry during color, fabric or chemistry changeovers, and because only the required chemistry volume is applied to the fabric, wet pick-up levels can be reduced by up to 50 percent—leading to 50 percent less water and energy consumption. Furthermore, in single-side applications, drying steps can be eliminated for various textiles, including those that are back-coated and laminated, thereby streamlining and simplifying the production process.

For the cooperation with Lidl within the project “Biodegradable textiles with prints” the CHT Group developed innovative recyclable textile print products.

These Lidl textiles are produced with CHT print pastes and pigments and were certificated by the internationally active consulting institute EPEA GmbH - Part of Drees & Sommer according to the Cradle to Cradle Certified™ Gold Standard. With this pilot project the companies demonstrate their sense of responsibility for people and the environment as well as their commitment in the field of circular economy.

According to the Cradle to Cradle approach, shortly C2C, products shall merge into a biological or technical cycle after the end of their life cycle. This re-use helps prevent waste and save raw materials. The impact on the environment and health of all of the ingredients of C2C textiles is already tested in the design stage and during manufacturing. C2C experts additionally ensure a gapless control of the manufacturing processes. They check the chemicals in use, make sure that the water is kept clean and that renewable energies are used. Since this control affects the complete textile supply chain, it guarantees absolute transparency.

The CHT Group can now offer high quality and sustainable substitutes for common textile print pastes with its first biodegradable print pastes and pigments.
