Startup insights

Value proposition

Unique platform technology combining molecular sieves and polymeric membranes that enables efficient, sustainable separation solutions while reducing process energy by up to 90% compared to thermal alternatives.

Problem solved

UniSieve's unique advantage is its proprietary molecular-sieving membrane platform, which combines exceptionally high selectivity with industrially relevant gas throughput, enabling separations that are difficult or uneconomic with conventional membranes. This allows customers to recover valuable gases such as Hydrocarbons, CO₂, SF₆, CF₄, and other specialty gases with lower energy consumption, smaller system footprints, and more attractive economics than many incumbent technologies.
