|Nitrous oxide is the third most damaging climate gas after methane andCO2 and is responsible for about six percent of anthropogenic climate effects.|
One unit of nitrous oxide is about 300 times more climate-damaging than the same amount of CO2. Nitrous oxide results mainly from the industrial production of nitric acid that is used in fertilizer manufacture and other processes. The novel EnviNOx process was developed by the company Uhde to remove the climate-damaging compound and other nitrogen oxides from the waste gas of industrial plants and convert it to the harmless substances nitrogen, oxygen and water. The catalyst EnviCat N2O from Clariant plays the key role in this process.
How nitrous oxide harms the climate and atmosphere
Anthropogenic nitrous oxide emissions amount to about ten million metric tons annually. Each year, the concentration of nitrous oxide in the atmosphere increases by 0.2 to 0.3 percent. Nitrous oxide emissions are harmful in two respects: they worsen the greenhouse effect and increase the hole in the ozone layer.
