    Biogas contains valuable methane.

    The challenge is separating the CO₂ efficiently without losing the gas you're trying to sell.

    Captivate BIO is our advanced CO₂ separation solution for biogas upgrading, designed to deliver high methane recovery with lower separation energy.

    Keep the methane.
    Remove the CO₂.

    At the heart of Captivate BIO is our highly selective solid adsorbent technology. Rather than relying on energy-intensive thermal regeneration, Captivate uses pressure-driven separation to selectively capture and release CO₂.

    This creates the potential for:

    • High methane recovery

    • High-purity product gas

    • Lower separation energy

    • Reduced methane losses

    • Competitive lifecycle economics

    • Modular deployment

    How it works

    Built for biogas applications

    Captivate BIO is designed for applications including:

    • Anaerobic digestion

    • Wastewater treatment plants

    • Agricultural biogas

    • Food and organic waste

    • Renewable natural gas production

    Why selectivity matters

    In biogas upgrading, removing CO₂ is only half the equation. Methane lost during separation is lost revenue.

    Captivate's adsorbent technology has been developed to strongly favour CO₂ over methane, creating the potential to achieve the required gas specification while recovering more of the valuable methane in the feed.

    More methane recovered. Less energy consumed.
    Better project economics.
