Algae are microorganisms that live in fresh and marine water, their main environmental role is to produce oxygen through photosynthesis. Saul Purton from the UK Algal Organization gave us a green alga from the chlamydomonas genus: Chlamydomona Reinhardtii. This alga has been studied for applications in different sectors but we decided to focus on feeding and biofuels applications. In particular we wanted to design for non-humans and we analysed green house emissions focusing on intensive cow farming for milk production.
CO2 emissions are mainly produced during feeding and fermentation (digestion) therefore we decided to build a bioreactor to feed cows in order to reduce emissions of up to 60%. The MIT Technology Review published an article about studies on this matter, showing how seaweed could cut cows’ carbon hoof print.
