Evonik Develops Isophorene Products From Renewable Acetone

March 2, 2022
New eCO series helps to reduce CO2 emissions and enables more sustainable solvents, composites and coatings.

By using renewable acetone, Evonik says it is now offering isophorone-based products with significantly lower CO2 footprint across all stages of the isophorone production chain. The new eCO products are available under the Evonik Crosslinkers brand families. Further downstream products will be launched in line with future market demand, according to the company.

Chemically identical to their fossil-based counterparts, according to the company, Evonik’s new eCO series products have the same characteristics in terms of processing, formulation and performance. In comparison to conventional isophorone products the new eCO products reportedly can help the industry to significantly reduce its global warming potential (GWP) and CO2 footprint. For example, Evonik says its Vestanat IPDI eCO contains 75% renewable carbon per mass balance.

“The new Vesta eCO series is the first step on our journey to climate neutrality. As a next step, we will release an updated life cycle analysis for our complete range/portfolio of i-chain products during 2022, thus offering our customers reliable information on carbon footprints to give them a clear picture of their reduction options” says Christian Schmidt, head of Evonik Crosslinkers business line. 

Mass balance is an accounting principle that matches inputs with outputs from production process, according to Evonik. Accounting ensures that sustainable end products match to the amount of renewable acetone purchased. The entire processes will be audited and certified by an independent body, the ISCC and REDCert standards, to verify the use of renewable resources across all stages of production. Based on strict bookkeeping and external auditing, the mass balance approach reportedly allows Evonik to adopt large-scale production and provide cost-effective offerings for its customers, while keeping track of each renewable molecule used.
