The gas treatment specialist ReiCat has delivered a large-scale H₂ recycling system to Symrise’s production site in Spain. Back in 2017, the company had already successfully commissioned its first ReiCat H₂ recycling system at a site in the U.S.

In the production of flavors and fragrances, large volumes of H₂ are used. The gas itself is not consumed, but it merely picks up impurities during the process. As early as 2017, Symrise recognized the potential to significantly reduce production costs and its CO₂ footprint through H₂ recycling and commissioned ReiCat to deliver its first system for a site in the United States. Now, a second ReiCat unit has been successfully commissioned at the Granada (Spain) site.

By deploying industrial gas recycling systems, Symrise underscores its innovative strength and pioneering role in sustainable operations.

The ReiCat H₂ recycling system captures the exhaust stream, purifies it in a complex multi-stage process, and returns the high-purity H₂ back into production. This enables recovery of up to 98% of the H₂ used, generating significant annual savings. At the same time, CO₂ emissions are avoided that would otherwise result from the production and transport of fresh H₂.

Michael Höfling, CEO of ReiCat said, “We are very pleased to continue our long-standing collaboration with Symrise. With our H₂ recycling systems, we make an important contribution to the circular economy in industrial processes. Projects like this demonstrate that H₂ recycling is an indispensable complement to Power-to-X. It also plays a vital role in establishing a sustainable H₂ economy.”
