Circular economy is one of the most important topics today to ensure a future worth living in. Lanza Tech is a company that has been dealing with this issue very intensively and also successfully for around 20 years and has implemented this project in China. For example, emissions from the steel industry are used to produce ethanol for cars, kerosene for airplanes or synthetic fibers for the textile industry. The basis for this is a new separation technology for carbon. This new technology uses microorganisms to convert the carbon emissions from agricultural and industrial processes into valuable chemicals. Thus, Lanza Tech has an intensive and successful cooperation with the industry. In this way, millions of tons of the climate effective CO2 are saved.
