From the Sector

Lenzing Group, a global producer of wood-based specialty fibers, is celebrating the 40th anniversary of its biorefinery and co-product brand LENZING™ Acetic Acid Biobased. The brand was first introduced on May 4, 1983, and has since become one of the leading and most trusted biobased acetic acid providers.

Over the past 40 years, LENZING™ Acetic Acid Biobased, which has a reduced carbon footprint that is 85% lower than that of fossil-based acetic acid, has continued to gain trust and support from customers. Specialty chemical company Evonik, and food production company Speyer & Grund Group, have been incorporating LENZING™ Acetic Acid Biobased in the production of their products since 1983. LENZING™ Acetic Acid Biobased has also been in high demand from the hygiene industry during the COVID-19 pandemic as an all-purpose cleaning agent in conventional and green products.

Pioneering a carbon neutral future in the biorefinery segment with a new offering
To mark the important occasion, Lenzing will introduce its first carbon neutral LENZING™ Acetic Acid Biobased to meet the growing sustainability needs of industries which predominately rely on fossil-based materials. Similar to the standard LENZING™ Acetic Acid Biobased, the carbon neutral LENZING™ Acetic Acid Biobased is produced using sustainably sourced beech wood as a universal replacement for non-renewable raw materials such as crude oil. By calculating, reducing and offsetting emissions during production processes, this expansion will create a more sustainable supply chain with highly functional products across various industries. From now on, Lenzing customers across the food, pharmaceutical, cosmetics, chemical and textile industries will be able to choose between carbon neutral and reduced carbon footprint acetic acid products.

Advancing circularity and carbon neutrality through efficient use of valuable resources
Lenzing’s biorefinery concept ensures that 100% of wood components are used to produce pulp for Lenzing’s botanic fibers, biorefinery products, as well as bioenergy, which is used to power Lenzing’s facilities. This makes Lenzing’s biorefinery sites almost fully energy self-sufficient to remain as carbon neutral as possible. To ensure a low carbon footprint, rail transportation is the preferred means for transporting LENZING™ biorefinery products, with trucks being leveraged in regions where rail transportation is not available.

Together with ClimatePartner, a recognized global leader in the design, development, and delivery of corporate climate action programs, Lenzing strives to reduce carbon emissions to net-zero through a mix of higher production efficiencies, use of renewable energy sources, low-carbon materials, and the dedicated support of an external nature-based carbon removal project. For instance, to offset remaining carbon emissions that cannot be reduced, Lenzing works with ClimatePartner to support and finance the switch to biomass as an energy source at a ceramic factory in Kitambar in northeastern Brazil. Using natural waste materials, like coconut shells, as renewable biomass for its energy production, the factory is able to produce roof tiles in a more climate-friendly way while saving on carbon emissions. Besides contributing to the fuel switch, the project also helps to reduce the deforestation rate in Brazil and avoid methane emissions that could result from the uncontrolled rotting of biomass.

B.I.G. Yarns unveils its new “SustainableYarns” platform, with Clerkenwell Design Week visitors the first to be invited to get on board and focus on what matters most for the design and manufacture of sustainable soft floorings.

The expert in polyamide (PA) 1 step 3 ply yarns offers a range of options for manufacturers to introduce sustainable yarns into carpet solutions and reach sustainability targets faster and more efficiently.

The Sustainable Yarns range creates opportunities to design with recycled content yarn (EqoCycle), to work with renewable resources (EqoBalance), and, following the launch of new polyamide 6 (PA6) EqoYarn at Clerkenwell Design Week, to also leverage the low-impact value chain.

New addition EqoYarn is a new low-impact PA6 carpet yarn based on the most recent innovations in polymer production, which enable yarn manufacturers to lower their carbon footprint by nearly 50% and give carpet manufacturers more options to reduce their impact.

For its EqoYarn Bulk Continuous Filament (BCF) production process, B.I.G. Yarns has selected the few best-in-class partners that have made major steps forward in terms of sustainability, and reduced their greenhouse gas emissions thanks to continuous investments in process efficiency, green energy, heat optimization and waste reduction. The result is EqoYarn with a carbon footprint of 4 kg CO2 eq/kg yarns, which is a CO2 reduction of up to 50% compared to conventional PA yarns.

EqoBalance PA6 yarns enable customers to reach an even higher CO2 reduction of up to 75%. Manufactured with polymers made from renewable resources such as organic waste from cooking oil instead of virgin or fossil feedstock, these yarns have a carbon footprint of 1.98 kg CO2 eq./ kg yarns. They help carpet manufacturers to create products with an extremely low carbon footprint.

EqoCycle PA6 yarns are fully recyclable and incorporate 75% recycled content originating from recycled and regenerated PA6 granules. With a carbon footprint of 4.64 kg CO2 eq./ kg yarns, they deliver the same high-quality performance of virgin PA6 yarn with the benefit of 37% CO2 reduction. EqoCycle yarns offer carpet manufacturers a sustainable alternative to help reduce the ecological footprint of their products and move towards a circular economy without jeopardizing the end-product quality.

In addition to the different CO2-reducing options, B.I.G. Yarns’ customers can access an unlimited colour range to elevate their designs. Its BCF technology for polyamide yarns, twisted and heat-set yarns, one-colour to multi-colour, between 650 and 15000 dTex, along with its colour studio, are available to support their creation of customised collections.

REVECOL® (Recycled Vegetable Cooking Oil) represents a new generation of textile chemical auxiliaries, which are high-performing and obtained from vegetable exhausted cooking oil.

Chemical auxiliaries play a crucial role in several stages of the textile production cycle, from material preparation to dyeing and finishing, but represent a complex challenge from the point of view of reducing environmental impact. Herein lies the revolutionary aspect of REVECOL® by ERCA: for the first time, not just one product, but a complete range of auxiliary chemicals is available that meets the criteria of circularity.

The result of ERCA's continuous research, REVECOL® are in fact born from critical waste materials (exhausted vegetable oils), which, thanks to an environmentally and safety-friendly manufacturing process, are transformed into a line of innovative chemical auxiliaries destined for the entire textile industry and its various applications: from underwear to home textiles.

EVECOL® by ERCA has obtained several certifications – GRS, RCS, listed into ZDHC Chemical Gateway, bluesign® and GOTS, and are also finalizing the third-party certified PCF (Product Carbon Footprint), - as well as various international recognitions – first prize RESPONSIBLE CARE®, in Italy, from Federchimica, inclusion in the BAT (Best Available Techniques) document from the European Community.

International technology group ANDRITZ has delivered, installed, and commissioned a mechanical textile recycling line and an airlay line at Novafiber’s nonwovens production mill in Palín, Guatemala. Both lines have been successfully operating since December 2022.

The recycling line – the second tearing line ANDRITZ supplied to Novafiber – processes post-industrial textile waste from Central America. The recycled fibers feed the latest ANDRITZ Flexiloft airlay line, which produces nonwoven end-products for the bedding and furniture industries – a true example of a circular textile-to-nonwoven approach. The production process ensures complete material use as a state-of-the-art edge trim recycling system returns any waste directly to the tearing and/or airlay line.

This combination of ANDRITZ tearing and airlay lines allows Novafiber to process large amounts of post-industrial garments, controlling the supply chain from raw material to final product. In addition, it enables energy savings and a reduced carbon footprint due to the reduction of shipments.

Based in Palín, Novafiber is a leading company in Guatemala for producing nonwovens from post-industrial textile waste for both the local market and export.

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.

Automotive carpets are typically multi-layered systems that can be challenging to recycle. By introducing a carpet made of 100% polyester, Autoneum now opens up new opportunities for vehicle manufacturers to meet their sustainability targets. The innovative carpet systems are fully recyclable, thus paving the way for an improved and more sustainable end-of-life recycling of electric vehicles. In addition, the high content of recycled PET as well as the zero waste and less energy-intensive production process further improve the carbon footprint of Autoneum’s new monomaterial needlepunch and tufted carpets.

Autoneum’s fully recyclable carpet systems ensure a closed material loop and are thus proof of the Company’s commitment to improving the sustainability performance of its products and manufacturing processes. The 100% polyester carpets build on the existing lightweight and particularly sustainable Autoneum Pure technologies: the carpet surface, for example, is made of Di-Light or Relive-1, while Hybrid-Acoustics PET is used for the decoupler. Thanks to Autoneum’s innovative alternative backcoating (ABC) process, which uses a thermoplastic adhesive instead of latex, the production of the new monomaterial needlepunch and tufted carpets also requires significantly less energy and no water at all.

Autoneum’s sustainable tufted carpet system made of 100% polyester is already in development for an electric model of a German vehicle manufacturer that will be available in Europe and Asia.

The Lenzing Group and VERBUND, an energy transition company, launched the first development stage of the largest ground-mounted photovoltaic system in Upper Austria. Together with its energy partner VERBUND, Lenzing is also paving the way for the transition to zero-emission mobility. The installation of electric vehicle charging infrastructure at the company’s premises underlines Lenzing’s commitment to the energy transition process.

Thanks to the ground-mounted photovoltaic system at the “Ofenloch” landfill site, Lenzing, in conjunction with VERBUND, is consistently moving forward on the path to a carbon-free energy supply and has commissioned the first half of the new photovoltaic system with a peak power of 2,780 kWp. Full commissioning of the system with a peak power of 5,560 kWp is envisaged in mid-October. Annual electricity production will amount to 6,000,000 kWh, which is expected to cut CO₂ emissions by some 4,400 tonnes per year. The Austrian pioneer in fiber production already commissioned three rooftop photovoltaic systems in spring/summer of 2022, with a peak power of 1,454 kWp and annual electricity production of some 1,508,000 kWh. The electricity flows directly into the company’s on-site production and will also power electric charging stations in future. In the first development stage, 16 wallboxes are set to be installed by the end of the year. A further 32 charging points are planned for 2023. The charging stations will be accessible to staff, visitors and the company’s own vehicle fleet.

“VERBUND’s photovoltaic operator model allows us to make the transition to solar power without incurring investment costs or risks. Thanks to the constant expansion in renewable energy, we remain on course to ecologize the value chain, while optimizing our carbon footprint, cutting costs and reducing the load on the grid, as we are using nearly 100 percent of photovoltaic power in our production,” explains Christian Skilich, Chief Pulp Officer of the Lenzing Group.

• Monomaterial solution contains renewably-sourced polypropylene from the Bornewables™ portfolio of circular polyolefins
• Trexel employs its proprietary MuCell® technology to deliver a range of lightweighting benefits
• EverMinds™ in action: reuse and design for recycling are focus of value chain collaboration

Borealis and Trexel, an expert in foaming injection and blow moulded parts, announce that they have co-developed a new plastic bottle based on a grade from the Bornewables™ portfolio of polyolefins made using renewable feedstocks derived 100% from waste and residue streams. The lightweight bottle – which will be showcased at the Borealis stand at the K 2022 (from 19 to 26 October 2022 in Düsseldorf) – is reusable and fully recyclable. It boasts a significantly lower overall CO₂ footprint because it is composed of renewably-sourced feedstock and produced in the foaming process.

The Bornewables™ portfolio of circular polyolefins helps reduce the carbon footprint while offering material performance equal to virgin polymers. Using Bornewables grades allows for design freedom and colour flexibility, and helps retain a premium look and feel. The grades – which are commercially available in Europe – help conserve natural resources because they are derived solely from waste and residue streams, for example from used cooking oil. Reusing waste already in circulation instead of fossil fuel-based feedstocks enhances the sustainability of applications made using the Bornewables grades.

The reusable new bottle developed by Borealis and Trexel retains its value over many life cycles thanks to the use of Trexel’s proprietary technology in tandem with Bornewables grades; as a material solution, the new bottle minimises the use of valuable raw materials. Moreover, converters consume less energy in the production process when using the MuCell® technology. The bottle thus helps close the loop on plastics circularity by way of design for recycling, the use of renewable feedstocks, and excellent material performance across multiple life cycles.
