Volunteer for a startup helping to reduce CO2 emissions and water pollution. BioBright helps the maritime industry to reduce CO2 and water pollution by using algae cultivation and monitoring systems. The maritime industry is a significant contributor to global environmental challenges, particularly regarding CO2 emissions and water pollution. BioBright is committed to tackling these urgent issues through its innovative algae-based technologies designed to reduce emissions and improve water quality within ports.

Algae-Based Technology for CO2 Absorption

BioBright cultivates algae inside ports, which naturally absorbs CO2 from the surrounding environment. Only 400 grams of algae can absorb 800 grams of CO2 every hour, making it a highly effective solution for carbon reduction in maritime ecosystems. By scaling algae installations in key port areas, BioBright helps ports significantly reduce their carbon footprint.
