UniSieve

UniSieve provides unique gas separation solutions that enable energy-efficient recovery of olefins from off-gas, flexible capacity expansion, and reduce emissions.

Our mission is to decarbonise hard-to-abate industries by replacing energy-intensive processes—such as distillation and amine scrubbing—with plug-and-play membrane systems that reduce energy use by up to 90%.

We focus on two major industrial challenges: olefin recovery and point source carbon capture. Our modular membrane platform offers scalable and energy-efficient alternative to conventional separation processes. UniSieve’s solutions are proven at scale and ready to accelerate the transition to a low-carbon future.
