Minimising mix

Life Science

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, animal feed containing less than 1% of the dried algae powder led to a 70-80% reduction in methane. The seagrass also contains many nutrients.

The big question is how sustainable production can be upscaled. Because red algae thrive on both sea water and sunlight, but grow at their own pace.

Meanwhile, others are using methane to make sunglasses or cutlery
