This is biogas refining without Evonik… … and this is biogas refining with Evonik. You might not see a difference, but our membrane technology serves as an exceptionally efficient method for biogas processing. Evonik has developed a cost- and energy-efficient process for converting crude biogas into ultrapure biomethane. And our process requires less energy and fewer chemical additives than conventional methods. A phenomenon known as the sieve effect keeps larger molecules in the membrane, while allowing smaller molecules to pass through. One benefit of this is that it allows us to purify methane to over 99 percent. Thanks to our high-performance polymer, we can now extract fuel from residual materials—without generating waste or emissions.
