From the Sector

Kelheim Fibres has been named as one of the finalists for the “Cellulose Fibre Innovation of the Year 2021” innovation award to be presented at the 2nd International Conference on Cellulose Fibres. With their plant-based and biodegradable fibres, the Bavarian viscose speciality fibres manufacturer presents a significant contribution to a plastic-free future for AHP (absorbent hygiene products). In contrast to other natural fibres, which are already available in fibre form and can only be treated on the surface, Kelheim’s technological flexibility offers the possibility to modify cross-sections and to introduce additives into the fibre matrix for intrinsic functionalisation. Through these modifications, Kelheim tailors its fibres specifically to the requirements of the individual nonwoven layers of the AHP and is able to achieve comparable performance values to synthetic fibres. 

In addition to this, the speciality fibres from Kelheim offer a very attractive ratio of cost to performance in comparison with other fibres of natural origin such as organic cotton. They are therefore not only able to enhance the performance of the final products more effectively than other bio-based alternatives, but are, at the same time, financially attractive. "Consumers of absorbent hygiene products are often faced with a choice between sustainable solutions made from fibres of natural origin and products with better performance and good fluid management properties produced using synthetic fibres,“ says Dominik Mayer, from Kelheim’s R&D team. „Our goal is to offer products to the consumer which combine both sustainability and performance. Our sustainable and functional fibre technologies now make this possible.“

The project is a good illustration of the central element of Kelheim Fibres‘ innovation philosophy: the identification of unsolved problems in the market and the development of solutions in close cooperation with experts along the value chain using open innovation techniques. Fibres from Kelheim also offer a significant contribution to overcoming one of the biggest global challenges of our time, by reducing the amount of plastic waste in the environment. Step by step, or in this case layer by layer – Kelheim Fibres is moving towards a vision of a plastic-free future.

Kelheim’s developments include the hydrophobized Olea fibre (for fast acquisition and efficient transfer of liquid and for better rewet values in the topsheet) as well as the Galaxy® fibre (for an efficient and optimised distribution of liquids in the Acquisition Distribution Layer (ADL) via capillary channels) and the Bramante fibre (which can store up to 260% of its own weight of liquids in chambers inside the fibre). Kelheim’s fibres can also be processed in the textile sector, to enable solutions in the field of reusable hygiene products such as menstrual underwear. All these fibres are already commercially available. Kelheim Fibres is cooperating with an innovative AHP manufacturer and an innovative nonwoven supplier to incorporate the fibres into new end products.

• Organic Waste Systems and TÜV confirm fiber biodegradability also in fresh water
• All white LENZING™ Viscose, Modal and Lyocell fibers are now certified for all environments
• Global legislators aim at limiting plastic waste persisting in the environment for centuries
• EU Single-Use Plastics Directive partly regulates usage of plastic products
• Biodegradable materials such as wood-based fibers are the best alternative to single-use plastics

The Lenzing Group received confirmation of the full biodegradability of its fibers in fresh water by the independent research laboratory Organic Waste Systems (OWS). The new and existing international certifications conducted by OWS and issued by TÜV Austria verify that LENZING™ Viscose fibers, LENZING™ Modal fibers and LENZING™ Lyocell fibers are biodegradable in all natural and industrial environments: in the soil, compost as well as in fresh and in marine water.

The biodegradability of cellulosic products and the synthetic fiber polyester was tested in fresh water at OWS according to valid international standards, e.g. ISO 14851. At the end of the trial period, LENZING™ wood-based cellulosic fibers, cotton and paper pulp were shown to be fully biodegradable in fresh water in contrast to synthetic polyester fibers. The fact that synthetic materials are not biodegradable leads to major problems in wastewater treatment plants and potentially marine litter. In turn, this not only harms fish and birds living in and close to the oceans but also all marine organisms and us humans.

“The Lenzing Group operates a truly circular business model based on the renewable raw material wood to produce biodegradable fibers returning to nature after use. This complete cycle comprises the starting point of the core value of sustainability embedded in our company strategy sCore TEN and is the ‘raison d’etre’ of our company”, says Stefan Doboczky, Chief Executive Officer of the Lenzing Group. “In living up to this positioning, we not only enhance the business of our suppliers, customers and partners along the value chain but also improve the state of the entire textile and nonwovens industries.”

Both the textile and nonwovens industries face huge challenges with respect to littering. If current trends continue, the oceans could contain more plastic than fish by 2050. Therefore, legislative bodies worldwide can no longer ignore the issue and have moved towards plastics legislation aimed at limiting the vast amount of waste. In response, European lawmakers issued the Single-Use Plastics Directive currently being transposed into national legislation in the EU member states.

Conventional wet wipes and hygiene products mostly contain plastic and were thus identified as one of the product categories to be singled out. Less polluting alternatives are generally encouraged by NGOs and legislators, e.g. products made of biodegradable wood-based cellulosic fibers. Plastic waste including microplastic can persist in the environment for centuries. In contrast, biodegradable materials are the best alternative to single-use plastics because they fully convert back to nature by definition and thus do not require recycling.

• Successful acquisition of Austrian plastics recycling company Ecoplast Kunststoffrecycling GmbH

Borealis, a leading provider of innovative solutions in the fields of polyolefins, base chemicals and fertilizers, announces today that it has fully acquired the Austrian plastics recycler Ecoplast Kunststoffrecycling GmbH (“Ecoplast”). Based in Wildon, Austria, Ecoplast processes around 35,000 tonnes of post-consumer plastic waste from households and industrial consumers every year, turning them into high-quality LDPE and HDPE recyclates, primarily but not exclusively for the plastic film market.

The expectation of Borealis is that the recycled PO market will grow substantially by 2021, which is the strategic rationale behind the acquisition. The company has made PO recycling a key element of its overall PO strategy because of its potential to support both growth and sustainability. Borealis has been an industry frontrunner in making polyolefins more circular. In 2014, it began offering high-end compound solutions to the automotive industry, consisting of 25% and 50% post-consumer recycled content. Borealis was also the first virgin PO producer to explore the possibilities of mechanical recycling, by acquiring one of Europe's largest producers of post-consumer polyolefin recyclates - mtm plastics GmbH and mtm compact GmbH – in July 2016. Since then it has continued to invest into the development of technology and new products in the area of circular polyolefins.

“Borealis recognises the increasing need for plastic recycling and sees the Circular Economy as a business opportunity. Borealis already has a long-term collaboration with Ecoplast and this acquisition is the next logical step in building our mechanical recycling capabilities. As an important complement to mtm in Germany, Ecoplast will help us address critical sustainability challenges and become a polyolefin recycling leader. Eventually, we want to use our experience to develop an effective blueprint for the end-of-use phases for plastics that can be applied in other parts of the world,” says Borealis Chief Executive Alfred Stern.

“We are very happy that the transaction with a strong and reliable partner such as Borealis has been successfully concluded and are looking forward to our common future activities on the recycling market. We have located potential synergies in many operative and strategic areas, especially in product quality R&D and future applications of polyethylene-film-recyclates. The combination of Ecoplast and Borealis holds the potential to be groundbreaking for the market,” says Ecoplast’s Managing Director Lukas Intemann.
