Innovation

Industry Problem

Airbuild addresses the critical problems of air pollution, water contamination, and urban carbon emissions by using microalgae to clean water, capture carbon, and generate renewable energy for healthier, more sustainable cities.

R&D Focus

Airbuild’s R&D focuses on developing microalgae-integrated biopanels that capture carbon, generate renewable energy, and filter water simultaneously. Their niche lies in creating sustainable, decentralized environmental solutions that combine biotechnology with clean energy and water treatment to support greener urban infrastructure and industrial applications.

Innovative Solution

Airbuild uses innovative microalgae-based biopods and biopanels that naturally capture carbon dioxide, filter organic contaminants from water, and generate renewable solar energy. This integrated, low-maintenance system transforms urban and industrial spaces into efficient, sustainable environments by improving air and water quality while producing clean energy, helping cities and businesses achieve their climate and sustainability goals.

Solution Effectiveness

Airbuild’s microalgae-powered biopanels demonstrate remarkable efficiency: each panel captures up to 200 kg of CO₂ annually, equivalent to the work of 15 mature trees, produces up to 400 watts of clean energy, and filters 500 gallons of water per year by removing organic contaminants, nitrogen, and phosphate. At scale, their biopods can capture 550 tons of CO₂ and filter 600,000 gallons of water per hectare annually. Additionally, Airbuild aims to reduce carbon capture costs to under $50 per ton, significantly lower than the industry average of $600–$1000 per ton, making their solution both impactful and economically viable.
