From the Sector

• Full utilization of production capacity possible at the site
• New EU environmental requirements will be fully and promptly satisfied starting in 2024

The Lenzing Group, a global provider of wood-based specialty fibers for the textile and nonwoven industries, is investing GBP 20 mn (equal to EUR 23.3 mn) to build a new, state-of-the-art wastewater treatment plant at its site in Grimsby, United Kingdom. The investment is part of the company’s plans to reduce wastewater emissions by 2022.

Once it has implemented this project, Lenzing will have biological wastewater treatment plants that meet the best available techniques (BAT) quality standard at all its production sites. The plant design, which will employ a new technology developed as part of a research project, is fully aligned with the UK regulator and supported by the local authorities.

The site’s current wastewater situation complies fully with the EU Water Framework Directive as well as all local laws and regulations. The investment has been approved by the Supervisory Board, ensuring that construction can start this year and the plant will be commissioned well before the UK-ratified EU directive1 goes into effect. This will be the largest investment since opening this lyocell site, which manufactures premium products for technical and innovative market segments, among other things.

Responsible water use
After modernizing the wastewater treatment plant at the company’s Purwakarta site in Indonesia, the construction of the new plant in Grimsby marks another big step toward reducing the Group’s wastewater emissions 20 percent by 2022 (against a 2014 baseline). Responsible water use is one of the core elements of Lenzing’s “Naturally positive” sustainability strategy and is largely executed by using water efficiently in manufacturing and employing state-of-the-art water treatment technologies.

• New air purification and sulfur recovery plant up and running at the Lenzing facility
• Another step closer to meeting sustainability and climate targets
• Self-sufficiency in raw materials further enhanced

Lenzing Group is continuing to make great strides toward achieving carbon neutrality across the Group. The successful completion and commissioning of an air purification and sulfur recovery plant at the Lenzing facility marks another milestone in the Group’s ambitious strategy. Lenzing has invested some EUR 40 mn in this project since construction began in 2019.

Using state-of-the-art technology, the plant will enable carbon emissions to be reduced by 15,000 metric tons at the Lenzing facility. This will also make the group more self-sufficient in securing vital raw materials for processing, which will bolster the site’s competitive standing in terms of sustainability.

“As a result of this investment, Lenzing has made further progress towards implementing its climate targets, while achieving much greater autonomy with regard to one of its core raw materials”, says Christian Skilich, Member of the Managing Board at Lenzing Group.

In 2019, Lenzing set the strategic target of halving its group-wide greenhouse gas emissions per ton of product by 2030. Its goal for 2050 is to achieve climate neutrality.

GREENBOATS, Sicomin and Bcomp are nominated as finalists for the JEC Innovation Awards 2021. The three project partners have been selected as finalists in the awards’ Renewable Energy category for their innovative Green Nacelle – the first offshore nacelle manufactured with natural fibre composites (NFC).

The Green Nacelle was designed by NFC innovators GREENBOATS, who were also responsible for the structural engineering, manufacturing and assembly of the nacelle.  By incorporating Bcomp’s ampliTex™ flax reinforcements, FSC certified balsa wood cores and bio-based resins, the Green Nacelle’s NFC construction saves approximately 60% CO2 equivalent and reduces the energy consumption by over 50% compared to a nacelle made with existing GFRP technology.

In addition to the lower CO2 footprint, the natural fibre composite structure also introduces viable options for the end of the nacelles’ life unlike traditional GFRP structures - an issue of increasing concern for the wind energy sector that presents a great opportunity for natural fibre composites to bring a sustainable change to this market.

Sicomin, the formulator and supplier of the leading range of GreenPoxy bio-based epoxy resin systems, supplied its DNV GL approved InfuGreen 810 resin system that was used to infuse the Green Nacelle’s main structural sandwich panels, as well as providing intumescent FR gelcoats, bio-based laminating resins and UV resistant clear coatings for the groundbreaking new nacelle.  Materials, as well as on-site technical support, were delivered by Sicomin’s German distributor TIME OUT Composites.

The winners of the awards will be announced during JEC Connect which will be held on the 1st and 2nd June 2021.
