Manufacturing is responsible for 25% of greenhouse gas emissions (GHGs). If we can find a use for all of that carbon we emit into the atmosphere we could go a long way towards mitigating and reversing global warming. Microbes may be the answer.
When we ferment grains and grapes to make beer and wine, it is microbes that do most of the work. Called acetogens, the microbes thrive on carbon dioxide (CO2). And we can make them even more effective in taking in GHGs using gas fermentation processes to create fossil-fuel-free rubber, plastic, paints, cosmetics, and more.
Today we rely on fossil fuels to make the kinds of products previously mentioned. But we don't have to. Instead, we can feed captured carbon monoxide (CO1), CO2 and hydrogen (H2) to acetogens and let these microbes grow in a bioreactor where the gasses are present. The microbes don't require oxygen. They thrive anaerobically.
