Materials manufacturer Covestro and SOL Kohlensà¤ure GmbH & Co. KG have announced a framework agreement for a supply partnership for biogenic carbon dioxide (CO2). With immediate effect, SOL, an important European suppliers of gasses and gas services, will supply the liquefied gas to Covestro sites in North Rhine-Westphalia, where it will be used to produce plastics, such as MDI (methylene diphenyl diisocyanate) and polycarbonate. Under the terms of the framework agreement, SOL Kohlensà¤ure will already supply up to 1,000 metric tons of biogenic CO2 this year. From 2023, the supply volume is to be increased substantially, enabling Covestro to save the same amount of CO2 from fossil sources at its NRW sites.
"We have set ourselves the goal to become fully circular. To this end, we want to convert our raw material base to 100% renewable sources. We are very pleased to have found a partner in SOL Kohlensà¤ure who will support us in this transformation with a pioneering spirit," explained Daniel Koch, head of NRW Plants at Covestro.
"We at SOL Kohlensà¤ure are advancing the shift to more sustainable CO2 sources. In this way, we are increasing security of supply, becoming independent of fossil raw materials, and reducing our environmental footprint at the same time," emphasized Falko Probst, sales manager at SOL Kohlensà¤ure.From Waste Product to Raw Material
The CO2 used is obtained by SOL Kohlensà¤ure from various sources, such as bioethanol and biogas plants. In these plants, CO2 is produced as a byproduct during the treatment of various biomasses, such as plant residues. This is separated by SOL Carbon Dioxide, purified, and then made available to Covestro production as a raw material. In this way, the supply partnership supports the circular concept and contributes to reducing emissions.Â Goal of Climate Neutrality by 2035
Covestro has set itself the goal of becoming fully circular. This also includes using alternative raw materials. Biomass, CO2, as well as end-of-life materials and waste, replace fossil raw materials such as crude oil or natural gas. Carbon is managed in a circular way. In realizing these ambitions, both companies are relying on long-term supply partnerships.
In addition to biogenic CO2, Covestro is investigating the use of other technical gasses from renewable sources. The materials manufacturer is already offering its customers its first sustainable products, such as climate-neutral MDI. With the expansion of its alternative raw material base, this portfolio is set to grow further in the coming years.
ISCC (International Sustainability and Carbon Certification) is an internationally recognized system for the sustainability certification of biomass and bioenergy, among others. The standard applies to all stages of the value chain and is recognized worldwide. ISCC Plus also encompasses other certification options for instance for technical-chemical applications, such as plastics from biomass. Covestroâ??s Lower Rhine sites in Leverkusen, Dormagen, and Krefeld-Uerdingen, Germany, are ISCC PLUS certified.
