Efforts are underway to remove CO2 from seawater. Shipping is currently responsible for around 3% of greenhouse gas emissions - a figure that is on the rise. For our planet every reduction counts.

Waste from breweries is a breeding ground for sustainable livestock feed. But the methane produced by these animals during the digestive process has a significant impact on the environment. For a female-led startup in Hawaii, however, the solution lies in a particular species of red algae called Asparagopsis taxiformis (instead of kangaroo babies). According to tests conducted on livestock,...

Seaweed can be used as a fire retardant. In Berlin, meanwhile, a female designer has developed a thin algae-based film and coated it with a natural dye. The aim?
