By recycling carbon from industrial off-gases; syngas generated from any biomass resource (e.g. municipal solid waste (MSW), organic industrial waste, agricultural waste); and reformed biogas, LanzaTech can reduce emissions and make new products for a circular carbon economy. LanzaTech’s carbon recycling technology is like retrofitting a brewery onto an emission source like a steel mill or a landfill site, but instead of using sugars and yeast to make beer, pollution is converted by bacteria to fuels and chemicals! Imagine a day when your plane is powered by recycled GHG emissions, when your yoga pants started life as pollution from a steel mill. This future is possible using LanzaTech technology.
