There’s a new way to make money and help the environment: It’s called the circular economy. The goal is to reuse materials in the production process, preventing would-be waste from reaching landfills.

LanzaTech, a steel producer in Illinois, demonstrates the principle. Conventional manufacturers release waste gases into the atmosphere during production. LanzaTech captures them before they are emitted as greenhouse gases and converts them into bioethanol. The bioethanol becomes a low-emissions fuel for motor vehicles. The process reduces pollutants from steel plants by 85 percent.
