Industrial emissions are responsible for producing most greenhouse gases and particulateemissions that are harmful to our health and our planet.       The business world has an increasing demand for innovative solutions to reduce greenhouse gasemissions in order to ensure human’s continued ability to live and thrive. A growing number ofcompanies are dedicated to the research and development of carbon-capturing and carbon-recyclingtechnology, which has already been adopted by airlines, home care companies, fragrance companiesand now textile production.       A biotech startup company has partnered with a sportswear brand to create the world’s first yarnand fabric made from waste gas captured from industrial emissions. Waste gas emitted from a steelmill is captured and reused to produce ethanol, which is later converted to polyester. The carbonrecycling technology is similar to that of a brewery； but instead of using sugars and yeast to makebeer, industrial emissions are converted by bacteria to fuels and chemicals.       The company’s goal is to help more businesses become “Carbon Smart” to achieve their climatechange goals around carbon reduction, by radically change how they source, utilize and dispose ofcarbon.      By capturing and upcycling industrial carbon emissions to make yarn, the finished garments notonly have a lower carbon footprint, but also ensure lower levels of community pollution.Recycling carbon emissions is key to the circular economy, which will keep fossil carbon in theground ─ reducing the use of fossil fuels and pollution when used to make value-added productssuch as polyester. In other words, the technology promotes circularity by keeping carbon in thematerial cycle.     This kind of waste-gas-based polyester not only has the same appearance but also the sameproperties and functionality of virgin polyester. Moreover, once the waste-gas-based textiles reachthe end of their useful life, they can be gasified and fermented without taxing the environment.
