Clariant announced in a press release it will continue to power its BU additives production facility in Knapsack, Germany, solely with 100% renewable electricity following the site’s pilot switch one year ago.
“Green electricity is already part of Clariant’s energy mix in facilities in Poland, Sweden and beyond. The Additives production facility in Knapsack is the first location in Germany to join the group in leading Clariant’s transition towards using renewable electricity,” said Stephan Neunerdt, Head of Production & Technology Flame Retardants, BU Additives, Clariant, in the release. “Knapsack is another example to demonstrate the feasibility for industrial manufacturers to take a holistic approach to reducing their environmental impact, carbon footprint and dependency on fossil resources, from energy consumption to raw material use.”
The site in Knapsack houses four plants dedicated to the production of environmentally-compatible flame retardants. Clariant’s halogen-free Exolit products provide fire protection to buildings, transport, electrical components and appliances, electronic devices, and furniture applications.
Knapsack’s changeover to 100% renewable electricity sourced from water and wind power is confirmed by Unbundled Energy Attribute Certificates. The switch was part of the site’s and Clariant’s commitment to reduce Scope 2 greenhouse gas emissions – indirect emissions from consumption of electricity. According to the release, it represents one aspect of the wider business unit and company-wide transition to more sustainable production and a reduced carbon footprint. This also includes the sourcing of renewable raw materials as feedstock. Clariant aims to reduce energy consumption by 30% and direct and indirect greenhouse gas emissions by 35% by the year 2025 (baseline 2013), according to the release.
At Knapsack, by switching to renewable electricity, 7300 t CO2 emissions are estimated to be avoided annually, based on planned annual electricity demand. Further, the site has introduced ethylene from renewable resources as a feedstock option for the new range of Exolit OP Terra flame retardants. “Terra” highlights renewable feedstock products with at least 50% Renewable Carbon Index (RCI) content based on renewable resources with a mass balance certification or real renewable content. According to the press release, Exolit OP halogen-free flame retardants are the first to be based on renewable sources and proven to be recyclable as confirmed by Fraunhofer LBF. By offering Terra solutions and using renewable raw materials Clariant will further lower greenhouse gas emissions over the product life cycle.
Knapsack carries REDcert2 certification – confirmed by TÜV Nord – which recognizes the site’s mass balance based use of renewable ethylene as an alternative to fossil-based feedstock for specific products.
“We are committed to expanding the use of renewable and reusable resources in our procurement, production and commercial system while reducing the resource consumption, said Stephan Lynen, Head of BU Additives, Clariant, in the release. “Our commitment to sustainability is without alternative.”
