Suntean

Suntean develops hyper–energy-efficient closed and semi-closed greenhouses engineered for the mass production of algae and plants. Our integrated design incorporates foam-based insulation and intelligent climate control that enable precise management of light, temperature, and humidity — conditions especially critical for algae cultivation. By integrating directly with biogas plants, Suntean systems capture and reuse CO₂ and nutrient sidestreams to drive circular production of high-value biomass. The result is a unique form of carbon capture and utilization (CCU) that transforms emissions into food, feed, and biofertilizers. Our modular, scalable design allows rapid deployment of carbon-negative bioresource hubs, combining profitability, sustainability, and resilience in the green transition. Suntean — turning carbon and waste into growth.
