From the Sector

CARBIOS and Zhink Group, specializing in two global industries, PET and textiles, announce the signing of a joint Letter of Intent to build a biorecycling plant in China using CARBIOS’ revolutionary enzymatic depolymerization technology to serve the global market. This agreement officializes collaboration towards a long-term partnership in view of a first licensing contract to build a plant with a minimum annual processing capacity of 50k tons of prepared PET waste and would contribute to accelerating a circular economy for plastic and textiles. China is a key market for CARBIOS, and this agreement would establish a presence in this dominant market.

With 67 million tons of PET produced annually, representing 61% of global production^[1], China is the world's largest PET producer. With regional and global demand for recycled PET growing, China also has the potential to take the lead in recycled PET (r-PET) production. In 2021, 58% of the world’s r-PET was consumed in Asia (with 38% in China^[2]) underscoring this region’s importance both as a major producer and consumer.

Furthermore, China is a key transformer of PET into resins and fibers used in numerous applications in the packaging and textile industries.  Most notably, China is the primary country for transforming PET into fiber, representing 78% of all PET fiber transformation in the world^[3].

For Zhink, the strategic focus is on the development of two global industries, PET and textiles, and to be a leader with sustainable competitiveness. Zhink is a major actor within the PET market with an annual production of 3 million tons of PET, serving domestic and global markets. CARBIOS has developed a enzymatic depolymerization technology that enables efficient and solvent-free recycling of PET plastic and textile waste into virgin-like products. The initial agreement between the two groups would allow Zhink to increase its recycled PET capacities and meet its sustainable competitiveness objectives by offering r-PET from enzymatic recycling: a circular recycling solution that can process all types of PET waste including hard-to-recycle waste (such as opaque and colored bottles, multilayer food trays and textile waste) while reducing CO2 emissions by 57%^[4] compared with virgin PET production. For CARBIOS, this agreement marks a significant step in the deployment of its technology worldwide and roll-out of its licensing model to achieve its ambition to become a leading technology provider in the recycling of PET by 2035. This Asia-based plant under license by Zhink would come in addition to the world’s first industrial-scale enzymatic PET recycling plant which is currently under construction in Longlaville, France.

The German Institutes of Textile and Fiber Research Denkendorf (DITF) are coordinating the research project, which is funded as part of the European Union's Horizon Europe research and innovation program. The aim of BioFibreLoop is to develop recyclable outdoor and work clothing made from renewable bio-based materials. The kick-off event took place in Denkendorf on June 26 and 27, 2024.

The textile industry is facing two challenges: on the one hand, production must become more sustainable and environmentally friendly and, on the other, consumers are expecting more and more smart functions from clothing.

In addition, the production of functional textiles often involves the use of chemicals that are harmful to the environment and health and make subsequent recycling more difficult.

Intelligent innovations must therefore ensure that harmful chemicals are replaced, water is saved and more durable, recyclable bio-based materials are used, thereby reducing the usually considerable carbon footprint of textile products. Digitalized processes are intended to ensure greater efficiency and a closed cycle.

For example, the BioFibreLoop project uses laser technology to imitate natural structures in order to produce garments with water and oil-repellent, self-cleaning and antibacterial properties. At the end result of the research work will be affordable, resource and environmentally friendly, yet high-performance and durable fibers and textiles made from renewable sources such as lignin, cellulose and polylactic acid will be available. All processes are aimed at a circular economy with comprehensive recycling and virtually waste-free functionalization based on nature's example. In this way, greenhouse gas emissions could be reduced by 20 percent by 2035.

The technology for the functionalization and recycling of bio-based materials is being developed in three industrial demonstration projects in Austria, the Czech Republic and Germany. At the end of the project, a patented circular, sustainable and reliable process for the production of recyclable functional textiles will be established.

The BioFibreLoop project has a duration of 42 months and a total budget of almost 7 million euros, with 1.5 million going to the coordinator DITF.

The consortium consists of 13 partners from nine countries who contribute expertise and resources from science and industry:

• German Institutes of Textile and Fiber Research Denkendorf (DITF), Coordinator, Germany
• Next Technology Tecnotessile Società nazionale di ricerca R. L., Italy
• Centre Technologique ALPhANOV, France
• G. Knopf’s Sohn GmbH & Co. KG, Germany
• FreyZein Urban Outdoor GmbH, Austria
• BEES - BE Engineers for Society, Italy
• BAT Graphics Vernitech, France
• Interuniversitair Micro-Electronica Centrum, Belgium
• Idener Research & Development Agrupacion de Interes Economico, Spain
• Teknologian tutkimuskeskus VTT Oy, Finland
• Det Nationale Forskningscenter for Arbejdsmiljø, Denmark
• Steinbeis Innovation gGmbH, Germany
• NIL Textile SRO, Czech Republic

CARBIOS and TOMRA Textiles, a tech venture set up by the sorting technology company TOMRA, announce the signing of an agreement to collaborate on establishing an efficient stream in Northern Europe from textile waste collection, sorting and preparation to recycling using CARBIOS’ enzymatic depolymerization technology at its first commercial plant currently under construction in Longlaville, France

The monomers obtained will be used to produce recycled polyester (r-PET) fiber, closing the loop for polyester textile circularity.

The innovations from both TOMRA Textiles and CARBIOS contribute to addressing critical gaps in the value chain and significantly increase textile-to-textile recycling from its current rate of 1%¹. By accelerating a circular economy for polyester, a sustainable alternative to incineration or landfill is made available.

TOMRA Textiles is on a mission to close the gap in textile circularity, by contributing to designing and scaling textile sorting plants. Under this partnership agreement, TOMRA Textiles will explore specific, tangible measures to enable the preparation of post-consumer polyester waste for biorecycling according to CARBIOS’ specifications.

CARBIOS' biorecycling technology involves breaking down polyester fibers into their basic components using enzymes, which are then used to produce high-quality recycled PET materials such as fibers for the textile industry. The breakthrough collaboration with TOMRA will redirect the challenging PET fraction of polyester textile waste towards biorecycling, showcasing a mutual dedication to pioneering recycling solutions for a circular economy.

Beaulieu International Group is investing €5 million to transition the fossil based energy supply of its Cushion Vinyl production plant in Wielsbeke, Belgium, to bio mass generated steam supply. A transition to renewable energy. To this end, B.I.G. is collaborating with A&U Energie, a company that converts non-recyclable wood waste into green energy and heat. This strategic move aligns with B.I.G.'s commitment to reach ‘net zero’ for their operations by 2030.

The transition from fossil energy to green steam and the switch to waste gas treatment without direct fossil energy brings significant benefits. First, the switch in technology will lead to 88% reduction in their Belgian Cushion Vinyl carbon footprint related to heat supply and waste gas treatment, compared to the current emissions. Second, the use of steam heating and electric energy provides improved energy efficiency. In addition, the use of steam systems is known for its safety and reliability, providing a safer and more stable heating solution for the Belgian Cushion Vinyl facility. Moreover, the switch to steam and electric energy allows for the use of green electricity in the future, if available.

In addition to transitioning to 100% green energy, Beaulieu International Group is also dedicated to advancing the circular economy. These efforts encompass various initiatives, including increasing the use of recycled and reused materials. For example, 50% of B.I.G.'s PVC floor coverings are already fully recyclable. Additionally, they are actively working to reduce the environmental impact of their solutions by 42% at the end of their life cycle, striving to minimize product emissions to nearly zero, and eliminating pollutants. Recently at the Belgian Flanders Flooring Days, Beauflor launched its Twilight collection, a cushion vinyl floor created with PVC from 100% bio and circular sources resulting in a 40% reduced CO₂ footprint compared to their conventional heterogeneous CV flooring for residential applications

Furthermore, their cushion vinyl brand Beauflor launched the ReLive concept, a specialized program designed for a circular future, ensuring the collection, sorting, and recycling of PVC flooring cutting waste. Currently, this program focuses on post-installation waste and is exclusively available in France, with the goal of expanding its reach to other EU countries.

Through the establishment of strategic partnerships dedicated to finding innovative ways to repurpose waste materials previously slated for incineration, B.I.G. underscores its commitment to sustainable solutions and collaboration with like-minded organizations. 75% of B.I.G.'s post-industrial waste is now being successfully recycled.

KARL MAYER GROUP has developed a sophisticated system for considerable energy savings when operating the cylinder dryers in its PROSIZE® sizing machines and BLUEDYE dyeing plant.

Saving costs with inline energy recycling
The innovation is called CASCADE and focuses on steam as a heating medium in cylinder dryers. And for good reason: according to the IPCC report by ITMF Zurich, one tonne of steam cost between USD 20 and just under USD 27 internationally in 2021. The new solution relies on reuse to reduce the amount of process energy required.
"CASCADE recirculates parts of the process steam in cylinder dryers, enabling genuine, efficient energy recycling within the machine," explains Karl-Heinz Vaassen, Head of Textile Drying at KARL MAYER.
The customer benefits from significantly lower energy costs and CO2 emissions. With a view to the Asian market, a dryer with 14 cylinders and a running time of 7,000 working hours can achieve cost savings of up to USD 17,000 per year.

Precise, real savings values are available when looking at the machine dashboard. A sensor provides real-time data on the amount of steam circulating in the circuit, from which the corresponding reduction in CO2 equivalents can be calculated.

Utilizing the pressure drop
CASCADE reuses part of the invested process energy and uses the flash-steam in conjunction with the pressure ratios, which - nomen est omen - decrease in cascades in the different zones of the cylinder dryer.
The highest working pressure prevails in the first cylinder section. The heat transfer medium steam emits large amounts of energy for yarn drying and condenses without temperature loss.

The resulting hot condensate is not immediately discharged from the machine, but is instead fed into a flash tank, where vapor exhaust is formed as a result of the pressure reduction. In conventional systems, the carrier medium for gases is only created in the return line towards the boiler house and is eliminated as undesirable. Instead of being utilised in the process, it escapes into the environment. With the CASCADE system, this "freshly recycled steam" is used for the heat supply in the second cylinder section, but not without prior treatment.

In the system patented by KARL MAYER, the recycled steam is intelligently mixed with live steam and thus raised to the level of the required process conditions for use in the cylinder section at the end of the dryer. Here, the fabric moisture is reduced to the desired residual value at medium pressure and temperature conditions.

Market launch is underway
CASCADE was filed for patent by the KARL MAYER GROUP. It was published in September 2023.
The innovative solution at no extra charge was presented at ITM 2024 in Istanbul and was a visitor highlight at the KARL MAYER GROUP stand.

From January 2024, CASCADE will be part of the PROSIZE® as standard. The first sizing machine with the upgrade for greater energy efficiency will be delivered in the second quarter of this year. It will go to a manufacturer in Europe. In the next step, CASCADE will be integrated into other dryer types and will also be available for the BLUEDYE.

• CARBIOS, L’OCCITANE en Provence and Pinard Beauty Pack join forces to establish an efficient European value chain for PET circularity
• The 100% biorecycled transparent bottle (from enzymatic recycling) will be on display at CARBIOS’ booth D02 at “Edition Spéciale” by LuxePack, held 4-5 June at the Carreau du Temple in Paris
• A key step towards achieving L'OCCITANE en Provence's eco-design commitment of 100% retail bottles made from 100% post-consumer recycled PET by 2027

CARBIOS and L’OCCITANE en Provence, an international cosmetics brand using natural and organic ingredients and long-term partner of CARBIOS, present a bottle in transparent PET made entirely from enzymatic recycling for a shower oil from the Amande range. In collaboration with converter Pinard Beauty Pack, this bottle exemplifies a shared desire to build en efficient European recycling sector to accelerate the transition to a circular economy for plastic, and meet brands' commitments for more sustainable packaging solutions. The bottle will be on display at CARBIOS’ Stand D02 at “Edition Spéciale” by LuxePack, the trade show dedicated to sustainable premium packaging, to be held on 4-5 June 2024 at the Carreau du Temple in Paris.

The 100% recycled PET bottle from CARBIOS' enzymatic depolymerization process was made with a European value chain committed to responsible consumption of sustainable materials. The bottle’s production began with the local supply of PET waste (already collected, sorted and prepared) to the CARBIOS industrial demonstrator in Clermont-Ferrand, France. The waste used consisted of colored bottles, multilayer trays and mechanical recycling residues, none of which are currently recycled using conventional technologies. CARBIOS deconstructed the PET waste into its original monomers, PTA and MEG, using its biorecycling technology. The resulting monomers were then repolymerized into new, fully recycled PET resins within Europe. In Oyonnax, France, these resins were blow-molded by Pinard Beauty Pack to create bottles according to L’OCCITANE’s specifications, and then filled with its shower oil at its Manosque plant.

Breaking new ground in plastics recycling means assessing the value chain from end to end. The big opportunities for the future are in fine-tuning the individual process steps; from the collection of recyclable materials to the recycling process and the end product. This is where the cooperation of Lindner and the EREMA Group comes in, officially launched following the 50/50 founding of the holding BLUEONE Solutions in August 2023 to which shares of Lindner Washtech were contributed. The expertise of EREMA, a manufacturer of extruders and filtration solutions for plastics recycling and the largest company within the EREMA Group, has now been combined with the expert know-how from Lindner Washtech, a leading provider of all-in-one solutions for shredding, sorting and washing plastic feed materials.

Data transfer ensures more efficient recycling processes
Process control is an especially important aspect of plastics recycling, which is why standardising the process control system was what the two companies focused on first. "Together, we have developed a platform that allows data to be exchanged between the extruder and the washing system," says Manfred Hackl, CEO of the EREMA Group at IFAT in Munich. "This enables us to analyse the data more precisely so that effective improvement measures can be deduced." All key parameters are taken into account and monitored via a digital interface. For example, it is possible to use information relating to the current throughput of the EREMA Pre Conditioning Unit to optimise the washing process as soon as possible so that it can compensate for fluctuations in capacity and achieve a significant increase in output. This data transfer represents a new step on the roadmap to digitalization.

High efficiency due to smart energy management
"To ensure sustainable recycling, it is necessary to find the right process for each application and to make sure that the individual process steps are perfectly coordinated," emphasizes Michael Lackner, Managing Director of Lindner. Coordinating the process steps has already achieved initial success in energy management, and a clear example of this is heat recovery. "We use the latent heat generated during the extrusion process as an energy source for the washing and drying process," explains Lackner. "This enables our customers to sustainably reduce their energy costs and carbon emissions".

Making the most of synergies along the value chain
Synergies need to be used to establish the quality standards specified for each end application. "The key question is how we can improve the end product and increase the overall efficiency of the recycling process at the same time," agree Manfred Hackl and Michael Lackner. This will only work if companies work together along the value chain. The industry leaders can already point to several examples where together they have improved recycling processes and made it possible to move away from downcycling. "An example of this is the recycling loop of HDPE starting material, which is processed into high-quality, food-safe rHDPE pellets using our two technologies," says Lackner. Lindner Washtech and EREMA continue to work intensively together to develop strategies for upcycling plastics and increase recycling rates.

Vision and technology are the key ingredients of a ground-breaking school blazer that is showing how businesses can move to a circular textiles economy.  
 
While many brands are grappling with the complexities of inevitable legislation and engrained business models, leading school uniform producer, David Luke, has launched a fully recyclable ‘circular’ school blazer that is designed to be recycled through Project Re:claim, the world’s first commercial-scale polyester recycling plant.
 
Project Re:claim is a joint venture between the UK’s largest charity textile collector, The Salvation Army, and leading circularity specialists Project Plan B. The plant opened in the UK in January 2024, and presents huge opportunities for brands to transition to textile-to-textile manufacturing models.
 
David Luke’s circular blazer has been introduced to the brand’s successful Eco-uniform range which has sold over 1.7 million Eco-blazers in the last decade. Up until 2023, David Luke’s Eco-blazer, like many recycled garments, has been made from recycled plastic bottles. But the company has been working with Tim Cross, CEO of Project Plan B and the Circular Textiles Foundation, to bring the 100% recyclable blazer to market.
 
Tim Cross said: “David Luke has grasped the opportunity to embed 100% recyclable and 100% recycled garments into their range, starting with the school blazer. We now have the technology to enable their blazers to be recycled without any separation of the garment, making it an efficient recycling process. The team at David Luke has worked tirelessly with their manufacturers to create a blazer that does not compromise on design or quality, and yet is much kinder to the environment.”
 
Every detail from the lining, buttons and zips to the inter-linings and adhesives, has been re-thought and re-designed to meet the demands of an everyday school blazer and to recycle the garment once it reaches its end-of-life. Up until now, when the blazers have eventually been handed down to siblings, or given to the local charity shop, there had been no end-of-life solution for polyester garments apart from incineration. Now, Project Re:claim can recycle the blazer to produce polyester pellets, which are then spun into yarn to be used for future David Luke circular blazers.
 
Cross continues: “David Luke has the vision to create a fully circular range, and we have the potential to supply recycled content. The possibilities are infinite in terms of the future of garment design and manufacturing.”
 
Kathryn Shuttleworth, Chief Executive of David Luke, said: “It is a natural next step for us to transition to a textile-to-textile model. We have been producing garments using recycled plastic bottles for 15 years, but we have always had an eye on developments in textile recycling and solutions for end-of-life garments.”
 
In 2020, David Luke was awarded the Queen’s award for Enterprise for Sustainable Development and in January 2023 the David Luke circular blazer achieved Circular Foundation Textile certification.
 
Shuttleworth added: “Our focus will always be on those essential ingredients for parents and children - style, durability and affordability. But we have a responsibility to change our business model to better protect children’s future and the environment. It has become our obsession to make uniforms that meet our customers’ demands. We are really excited about the future as we continue to develop our range.”
 
Majonne Frost, Head of Environment and Sustainability for Salvation Army Trading Company, said: “Our vision is to enable companies to produce uniforms, corporate wear, fashion garments and textile ranges using recycled polyester.  We have the infrastructure to collect donations at scale and we now need companies to step up. This is an opportunity for companies to make a commitment to significantly reduce their environmental impact, and David Luke are showing us how that is possible.”

Lightweight design is a key enabler for addressing the energy transition and sustainable economy. Following the liquidation of the state agency Leichtbau BW GmbH, a consortium consisting of the Allianz Faserbasierter Werkstoffe Baden-Württtemberg (AFBW), the Leichtbauzentrum Baden-Württemberg (LBZ e.V. -BW) and Composites United Baden-Württemberg (CU BW) now represents the interests of the lightweight construction community in the State.

The Lightweight Design Agency for Baden-Württemberg is set up for this purpose on behalf of and with the support of the State. The Lightweight Construction Alliance BW is the central point of contact for all players in the field of lightweight construction in the State and acts in their interests at national and international level. Professor Markus Milwich from the German Institutes of Textile and Fiber Research Denkendorf (DITF) represents the agency.

The use of lightweight materials in combination with new production technologies will significantly reduce energy consumption in transportation, the manufacturing industry and the construction sector. Resources can be saved through the use of new materials. As a cross-functional technology, lightweight construction covers entire value chain from production and use to recycling and reuse.

The aim of the state government is to establish Baden-Württemberg as a leading provider of innovative lightweight construction technologies in order to strengthen the local economy and secure high-quality jobs.

Among others, the "Lightweight Construction Alliance Baden-Württemberg" will continue the nationally renowned "Lightweight Construction Day", which acts as an important source of inspiration for a wide range of lightweight construction topics among business and scientific community.

Professor Milwich, an expert with many years of experience and an excellent network beyond the State's borders, has been recruited for this task. In his role, Milwich also represents the state of Baden-Württemberg on the Strategy Advisory Board of the Lightweight Construction Initiative of the Federal Ministry for Economic Affairs and Climate Action, which supports the cross functional-technology and efficient transfer of knowledge between the various nationwide players in lightweight construction and serves as a central point of contact for entrepreneurs nationwide for all relevant questions.

From 2005 to 2020, Professor Milwich headed the Composite Technology research at the DITF, which was integrated into the Competence Center Polymers and Fiber Composites in 2020. He is also an honorary professor at Reutlingen University, where he teaches hybrid materials and composites. "Lightweight design is an essential aspect for sustainability, environmental and resource conservation. I always showcase this in research and teaching and now also as a representative of the lightweight construction community in Baden-Württemberg," emphasizes Professor Milwich.
