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.

Really love the idea that we continue to look to nature and natural processes for solutions where possible-- microbes, trees, algae, oceans, wetlands. We have a lot of resources that we need to protect, and if we do then they can pay us back N times over in being a part of the climate solution

Hi Matt, I still see a role for oil as a resource but for the byproducts and not for the burning. Carbon fibre represents an enormous opportunity for the industry to do a 180 and I don't know why this is not happening at an accelerated rate. Cars built with carbon fibre frames would make EVs go further on a single charge. They could replace aluminum and steel. Carbon filaments and nanotubes produced from oil could be used not just for automotive purposes, but for thin-film electronics, actuators, electromagnets, filters, plastics and pharmaceuticals.

Why bury treasure? when we can turn it into biomass and simultaneously release oxygen into the atmosphere? Some day we'll look at all that CO2 we wasted for decades, by releasing it into the atmosphere and wonder why we didn't use it all as a feedstock.
