Through application of LanzaTech’s carbon capture and reuse process using wastes and residues, there is neither direct nor indirect land use change nor impact on food or water security.
Future platform chemical products represent a form of carbon sequestration, in which carbon is captured and stored in end products such as plastics that are derived from these chemicals. The process at LanzaTech’s demonstration facility in China has earned a world-first sustainability certification from the Roundtable on Sustainable Biomaterials (RSB) Services Foundation.
|GHG Emissions||GHG emissions reductions of over 75% compared to petroleum fuels on a well-to-wheel basis
Globally, up to 150 M tonnes of carbon dioxide emissions could be avoided by re-using steel mill gas residues alone
|Air Pollutants||LanzaTech allows a >85% reduction in particulate matter and NOx compared to CHP|
|Land Use||No use of land beyond plant installation at industrial site|
|Water Use||Process water can be treated and recycled|
|Sustainability Assessment||Roundtable on Sustainable Biomaterials (RSB), Tsinghua University in China and Michigan Tech University in the USA have assessed and quantified the environmental impacts, including GHG emissions associated with all stages of the process.
E4Tech, a London based environmental assessment group that has been at the forefront of methodology development, will be maintaining an independent, rigorous approach to LanzaTech’s sustainability assessment and has shown Life Cycle Analysis results of 76.6% GHG reduction for LanzaTech's steel mill to ethanol process.
|Energy Efficiency||~60% superior energy conversion efficiency
In addition, off-gas carbon is captured in useful liquid fuels, rather than used for electrical energy, which could be provided by other means, such as solar, hydro or wind
