• Einweihung SUSKULT-Demonstrationsanlage auf der Kläranlage Emscher-Mündung

Die Versorgung der wachsenden Bevölkerung mit nachhaltigen, lokalen und qualitativ hochwertigen landwirtschaftlichen Produkten ist eine enorme Herausforderung. Um den Bedarf gerade in urbanen Regionen zu decken, müssen neuartige Agrarsysteme etabliert werden. Ein Vorreiter auf dem Gebiet ist das Verbundprojekt SUSKULT, in dessen Rahmen jetzt eine Demonstrationsanlage feierlich eingeweiht wurde. Die Anlage steht auf dem Gelände einer Kläranlage des Wasserwirtschaftsverbandes Emschergenossenschaft in Dinslaken. In der SUSKULT-Vision sind dort alle wesentlichen Ressourcen für den Anbau von Gemüse und Co. – Nährstoffe, CO2, Wasser, Wärme – in großen Mengen verfügbar.

Endliche Phosphatressourcen, hoher Energieaufwand bei der Düngemittelproduktion, Verschmutzung von Gewässern und Böden durch Phosphor und Stickstoff – hinzu kommen Probleme in den Lieferketten durch Ereignisse wie Corona sowie massive Preissteigerungen aufgrund globaler Krisen. Das sind sicher keine guten Voraussetzungen, um die Erträge frischer und hochwertiger Agrarprodukte nachhaltig zu steigern. Expertinnen und Experten sind sich jedoch einig: Genau das muss geschehen, um eine größere Unabhängigkeit der deutschen Agrarwirtschaft sicherzustellen, zukünftigen Krisen gestärkt begegnen zu können und gleichzeitig besser auf Folgen des Klimawandels vorbereitet zu sein. Für den erforderlichen Transformationsprozess war bis dato der Zeitraum von 2040 bis 2050 vorgesehen – aktuelle Entwicklungen erfordern eine frühere Umsetzung.

Zu den zentralen Lösungsansätzen zählen mehr Regionalität und eine Kreislaufführung der eingesetzten Ressourcen. »Damit beschäftigen wir uns bei SUSKULT, indem wir ein Agrarsystem an Kläranlagen integrieren. Hier finden wir zum einen die für einen gartenbaulichen Anbau von Produkten notwendigen Ressourcen – Nährstoffe, CO₂, Wasser und Wärme. Zum anderen sind Kläranlagen häufig zentrumsnah verortet, was die Transportwege zu den Konsumentinnen und Konsumenten minimiert«, erklärt Volkmar Keuter vom Fraunhofer-Institut für Umwelt-, Sicherheits- und Energietechnik UMSICHT, der das Verbundprojekt koordiniert. »Mit der Einweihung der Demonstrationsanlage auf der Kläranlage Emscher-Mündung der Emschergenossenschaft (EG) beschreiten wir nun konsequent den nächsten Schritt auf dem Weg hin zu einem zukunftsfähigen Agrarsystem.«

In den vergangenen drei Jahren seit Projektstart haben die insgesamt 15 Partner – darunter Universitäten, Forschungseinrichtungen sowie Institutionen aus Industrie und Wirtschaft – die wissenschaftliche Grundlage für das Vorhaben gelegt und die einzelnen Bausteine entwickelt. Diese werden jetzt erstmals auf einer der größten Kläranlagen Europas zu einer Prozesskette zusammengeführt und in der Praxis getestet. »Die Modernisierung der Wasserwirtschaft ist seit Jahren getrieben durch Themen wie Energie- und Ressourceneffizienz. Phosphorrecycling aus Klärschlamm haben wir z. B. auf der Kläranlage Emscher-Mündung bereits erfolgreich halbtechnisch pilotiert. Die SUSKULT-Vision, dass Kläranlagen künftig sämtliche Nährstoffe liefern, die für die Agrarproduktion eingesetzt werden, stellt daher einen logischen nächsten Schritt dar«, so Dr. Emanuel Grün, Technischer Vorstand der Emschergenossenschaft.

Von außen betrachtet wirkt die Demonstrationsanlage, untergebracht in zwei Seecontainern und in einem Teil des sogenannten Technikums der Emschergenossenschaft, relativ unscheinbar. Anders sieht es im Inneren aus: Hier befinden sich die insgesamt fünf SUSKULT-Bausteine. Drei von ihnen wandeln die Ressource Abwasser in NPK-haltigen Flüssigdünger (NPK: Stickstoff, Phosphor und Kalium) um, in den anderen beiden wird dieser Dünger zur Kultivierung von z. B. Gemüse und Salat sowie gesundheitsfördernden Lebensmitteln wie Süßkartoffeln und Moringa verwendet. Der Anbau erfolgt vertikal, das ist platzsparend und saisonunabhängig. Des Weiteren werden Wasserlinsen produziert, die über einen hohen Vitaminanteil verfügen und als regionaler Sojaersatz dienen können.

Mit der Demonstrationsanlage betritt der SUSKULT-Verbund Neuland. Entsprechend wichtig ist die technische und wissenschaftliche Begleitung: Während einzelne Bausteine wie etwa das Vertical Farming fernüberwacht werden, bedarf der gesamte Versuchsbetrieb einer intensiven Betreuung. Hier arbeitet ein Team aus Studierenden, Forschenden und Technik Hand in Hand.

The Lenzing Group, a leading provider of wood-based specialty fibers, is expanding its global clean electricity portfolio by gradually transitioning to green energy at its production site in Nanjing. This will enable its Chinese subsidiary Lenzing Nanjing Fibers to use electricity derived solely from renewable sources from 2023 onwards and reduce the site’s carbon emissions by 100,000 tonnes annually. Lenzing only recently announced the transition to green electricity at its Indonesian production facility.

In 2019, Lenzing became the first fiber producer to set a target of halving its carbon emissions by 2030 and becoming climate neutral by 2050. This carbon reduction target has been recognized by the Science Based Targets Initiative. In Nanjing, Lenzing is currently investing in cutting its carbon emissions and converting a standard viscose production line to 35,000 tonnes of TENCEL™ branded modal fibers. Thanks to this move, the Chinese site will exclusively produce eco-friendly specialty fibers.

The company aims to generate more than 75 percent of its fiber revenue from the wood-based, biodegradable specialty fibers business under the TENCEL™, LENZING™, ECOVERO™ and VEOCEL™ brands by 2024. With the launch of the lyocell plant in Thailand in March 2022 and the investments in existing production sites in China and Indonesia, the share of specialty fibers in Lenzing’s fiber revenue is set to exceed the 75 percent target by a significant margin as early as 2023.

• Values from the past 30 years more relevant than ever and are reflected in recent growth

During its 30^th anniversary, the international OEKO-TEX^® Association is still seeing positive business development despite numerous global challenges. In total, OEKO-TEX^® issued more than 36,000 certificates and labels in the past financial year – an increase of 14% compared to the previous year. The STeP by OEKO-TEX^® facility certification recorded the strongest growth, almost doubling compared to 2020/2021. The number of labels and certificates issued increased from 31,696 to 36,084 between July 1st, 2021, and June 30th, 2022.

"Since OEKO-TEX^® was founded in 1992, our business practices have been aligned with our core values," says OEKO-TEX^® Secretary General Georg Dieners. “Sustainability, trust and safety build upon each other and are the basis of transparent and sustainable action. We underpin responsible action with our independent scientific methods and are valued in the industry as an effective, solution-oriented partner.” In the past financial year, this was reflected in the new Impact Calculator, with which STeP by OEKO-TEX^®-certified companies calculate their CO₂ emissions and measure their water consumption to ultimately reduce both. For OEKO-TEX^®, a sustainable future is inextricably linked to a transparent status quo. "By setting the highest standards and communicating them openly, we encourage companies and consumers to do the same," says Dieners.

To maintain trust and credibility, OEKO-TEX^® includes external perspectives. The International Advisory Board reviews proposals of the OEKO-TEX^® Working Groups and provides important impetus for continuous optimization of the standards. Additionally, a Public Stakeholder Consultation was conducted in March 2022 to gain comprehensive insights from all interest groups. These are now being integrated into the further development of the standards and services. The investments of the past financial year reflect how important quality assurance and product control are for the OEKO-TEX^® Association: Almost 40% of the total expenditure flowed into these two items.

In the meantime, the basic business continues to progress successfully. The number of STANDARD 100 by OEKO-TEX® certificates issued in the 2021/2022 financial year exceeded 25,000 for the first time. More than 15,000 chemicals, colorants and auxiliaries were certified with ECO PASSPORT by OEKO-TEX^®.

In autumn 2022, OEKO-TEX^® will launch a certification to help companies comply with upcoming due diligence laws. With RESPONSIBLE BUSINESS by OEKO-TEX^®, OEKO-TEX^® is responding to the increasing global expectations of compliance with due diligence requirements in companies. The new standard is based on the EU proposal for due diligence, the German Due Diligence Act, which will come into force from 2023, and numerous other international legislative proposals.

• Partnership with green power producer Enery and Energie Steiermark realizes construction of a photovoltaic plant with 5.5 MWpeak capacity
• Strategic investments in renewables boost energy independence and reduce carbon footprint

The Lenzing Group has signed an electricity supply contract with green power producer Enery and Energie Steiermark to finance a photovoltaic plant in the Deutschlandsberg region (Styria). The electricity generated will supply the fiber and pulp plant at the Lenzing site after commissioning from the fourth quarter of 2023. The electricity supply contract is limited to 20 years.

The plant’s output will amount to 5.5 MWpeak. This corresponds to the average annual electricity demand of more than 1,700 households. Several photovoltaic systems are already being installed at the Lenzing site, including the largest ground-mounted plant in the province of Upper Austria, whose commissioning is imminent.

In 2019, Lenzing became the first fiber manufacturer to set a target to reduce its carbon emissions by 50 percent by 2030 and to be climate neutral by 2050. This carbon reduction target has been confirmed by the Science Based Targets Initiative. Lenzing is also currently investing in reducing carbon emissions at other sites worldwide. Only recently, the Lenzing Group announced that its Indonesian site will also be relying on green energy in the future.

• TFI Aachen, Gerflor, Findeisen und Object Carpet stellen neuen „Produktpass Nachhaltigkeit“ vor, der Bewertung und Einsatz umweltgerechter Bodenbeläge vereinfachen soll.

Nachhaltigkeit hat sich längst zu einem zentralen Kriterium zukunftsgerechten Bauens entwickelt. Vor diesem Hintergrund spielen auch Nachhaltigkeitssysteme bei Bauprojekten eine immer größere Rolle. Doch für Architekten, Bauherrn oder auch Entscheider der Öffentlichen Hand ist es häufig schwierig, bei der Vielfalt der Zertifizierungen den Durchblick zu behalten.

Der von der TFI Aachen GmbH in Kooperation mit Gerflor – Spezialist für elastische Bodenbeläge –, Nadelvlies-Hersteller Findeisen sowie Teppichboden-Hersteller Object Carpet entwickelte „Produktpass Nachhaltigkeit“ bietet eine intelligente, niederschwellige Lösung. Das übersichtliche Datenblatt ordnet die Nachhaltigkeitsleistungen von Produkten den entsprechenden Zertifizierungssystemen zu und bewertet diese. Dies führt zu deutlichen Zeit- und Kosteneinsparungen im Planungsprozess –sowohl bei den Planenden und Bauherren als auch bei den Unternehmen.

Der Produktpass gibt einen durch die unabhängige Zertifizierungs- und Produktprüfstelle des TFI verifizierten Überblick zu den zentralen Eigenschaften eines Bodenbelags. Die zentralen Qualitätsmerkmale – zum Beispiel Rohstoffeinsatz, verwendete Materialien oder auch Verpackung – werden den konkreten Kriterien der Nachhaltigkeitssysteme DGNB, LEED, BREEAM, BVB sowie Cradle to Cradle zugeordnet und bewertet.

„Durch diesen neuen Ansatz entfällt das sonst äußerst zeitraubende Abgleichen von Produkt-Daten bzw. -Deklarationen mit den jeweiligen Zertifizierungssystemen. Planer können somit auf einen Blick sehen, wie sich der Einsatz eines bestimmten Bodenbelags konkret auf die Nachhaltigkeit des Projektes auswirkt,“ so Dr. Jens-Christian Winkler, Prokurist und Leiter der Zertifizierungsstelle im TFI:

Zum Start des neuen „Produktpasses Nachhaltigkeit“ sind bereits zahlreiche Datenblätter zu den elastischen Bodenbeläge von Gerflor sowie aktuellen Nadelvlies-Produkten von Findeisen sowie Teppichböden von Object Carpet verfügbar – sukzessive wollen alle Projektpartner den Produktpass für ihr komplettes Sortiment bereitstellen.

Für die Zukunft ist eine deutliche Erweiterung um neue Hersteller und Produktbereiche über den Bodenbelag hinaus geplant. Zudem sollen die Daten kontinuierlich auf weitere Nachhaltigkeitssysteme ausgeweitet und durch entsprechende Schnittstellen auch digital – zum Beispiel für die BIM-Planung – zur Verfügung gestellt werden.

adidas has unveiled the latest in its Made with Nature Capsule Collection with a new Ultraboost 22 Made with Nature and Made with Nature apparel joining the range as the brand continues its mission to call time on conventional materials and design out finite resources.

Designed in balance with the planet, the women’s Ultraboost 22 Made with Nature takes the forward-thinking elements of the Ultraboost 22 and amplifies them with natural materials. The shoe is made in part with natural materials – 40% of the knitted upper is made with lyocell, a material created with cellulosic fibers made from sustainably grown wood.

Launching alongside the Ultraboost 22 Made with Nature is a new Made with Nature apparel range, including a performance running wear look for men and women. The apparel range is made with at least 50% organic cotton.

Christopher Wheat, Global Category Director Running Footwear said: “At adidas, we understand that change is not only possible, it’s an urgent necessity. With Made with Nature, we are on a journey to a world beyond plastic. We’re calling time on conventional materials and methods of make. Once depleted, there’s no coming back for fossil resources. But when we design in synergy with natural processes, when we make with nature, we can use materials that regrow or regenerate – and change the way products are made."

Global Fashion Agenda (GFA) has launched a new international edition of Global Fashion Summit. Traditionally held in Copenhagen, the new edition in Singapore will further focus on the perspectives of manufacturers and supply chain partners to deeper understand how the industry can collaborate to reduce social and environmental impact in the entire value chain. Global Fashion Summit: Singapore Edition will take place on 3 November 2022 at Hilton Singapore Orchard.

The theme of Global Fashion Summit: Singapore Edition continues GFA’s focus on ‘Alliances For a New Era’. Under this theme, the Summit will call on the industry to accelerate change - encouraging more alliances between manufacturers, suppliers, investors, brands, NGOs, policymakers and more. It will also examine cross-industry alliances, in a bid to accelerate the transition to a net positive reality.
 
By bringing the forum to Asia, the new edition will include even more manufacturer and supply chain partner voices in the programme to discuss sustainability challenges, differences, and opportunities to collaborate with brand executives on equal terms. Plenary sessions will consider topics such as:

• Renewable energy transformation – what does concrete transformation look like from tier 1-3 perspectives and what measures are needed to implement it?
• Better wage systems – how can the industry establish fair compensation, underpinned by fair purchasing practices that will help end poverty for millions of garment workers?
• Performance measurement – how can the industry accurately measure sustainability performance and tackle data credibility challenges?

Half of the programme will be dedicated to educational and action-oriented business case studies with options for direct interaction and live reactions. These will include tangible learnings and concrete recommendations to mobilise guests to take immediate action following the event.
 
The event will foster further collaboration across stakeholder groups through productive roundtable sessions that create an exchange of views among key decision makers in both the public and private sectors. These meetings will be designed and set up to drive commitments and new alliances for concrete action.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

• Recypur successfully starts up a complete airlay line delivered by ANDRITZ for its mill in L’Alcúdia, Spain

The airlay line is designed for recycling of post-industrial and post-consumer foam and was developed specifically for the bedding and furniture industry, with material heights reaching 20 cm and densities of up to 120 kg/m3. Experimental tests carried out together with experts from ANDRITZ Laroche led to the conclusion that the mechanical method for recycling polyurethane is the most versatile and reliable.

With a capacity of 1.2 t/h, this airlay line enables Recypur to supply new mattresses made of industrial & post-consumer foam waste from old mattresses. This well proven process allows to reduce the environmental impact, increase self-sufficiency and eventually reduce the use of polyurethane. Such a set-up also allows multiple functional materials to be incorporated into the blend, such as flame-retardant, conductive and insulating fibers, among others. Thanks to this tailored approach, Recypur is now able to expand its diversification, innovation and reputation on the Spanish market.

The scope of supply includes a blending line with five feeders, an Exel 1500 for fine opening, an Airlay Flexiloft+ with 2.20 m working width, a recycling machine and an oven.

Airlay lines strongly support the circular economy and are part of ANDRITZ’s comprehensive product portfolio of sustainable solutions that help customers achieve their own sustainability goals in terms of climate and environmental protection.

Recypur, based in the Spanish province of Valencia, is part of DELAX, a Spanish group specialized in manufacturing and commercialization of innovative beds and mattresses. This company is the first Spanish manufacturer of recycled flexible polyurethane foam cores from post-consumer foam waste.

Adient, a supplier of seating systems for the automotive industry, has entered into a cooperation with Swedish steelmaker H2 Green Steel (H2GS) to reduce the carbon footprint in its value chain.
 
On 1st September Michel Berthelin, Executive Vice President Adient EMEA, and Henrik Henriksson, CEO of H2 Green Steel, have mutually signed an agreement to supply fossil-free steel with low carbon footprint from 2026 on and subsequently use it in Adient's metal products.

Michel Berthelin explains the background to the cooperation: “As a company, we are committed to the Science Based Targets Initiative, a collaboration between leading global institutions to set a science-based climate target. We also support the Carbon Disclosure Project, which helps companies and cities to understand and disclose their environmental impacts. The decision to shift parts of the steel volume sourced for our production to a steel with low carbon footprint is part of our sustainability strategy. It is our goal to reduce emissions at our production sites that are caused directly by our own sources or indirectly by our energy suppliers by 75% by 2030. In parallel, we aim to reduce emissions along our supply chains by 35% over the same period. In doing so, Adient actively fosters the industry's transformation towards a more responsible use of natural resources.”

Steel from H2 Green Steel is produced with up to 95% less CO₂ emissions compared to conventional steel production. The company achieves this by replacing coal with green hydrogen in production and by the use of electricity from non-fossil sources. In this way, mainly water and heat are produced as waste products.
