At the Paris Climate Conference 2015, 195 countries agreed on a global climate deal. It includes a global action plan that should limit global warming to significantly lower than 2 °C in order to counteract dangerous climate change. Between 2007 and 2016, LANXESS already saved 13.8 million metric tons of climate gas emissions. However, it does not stop there: CO2 emissions are set to drop by 25 percent in comparison with the base year 2015.
Other examples of this include two new nitrous oxide reduction units at the production site in the Uerdingen district of Krefeld. The first thermal nitrous oxide reduction unit began operation there back in 1992, and since then it has accounted for emissions cuts of approximately 85 percent. The second unit went online in 2009. In a thermal process, nitrous oxide is split off from the waste gas stream generated by adipic acid production and is broken down into oxygen and nitrogen at temperatures of over 1,000 °C. The heat that this creates, in turn, generates steam that is fed into the site’s supply network.
Another example can be found in Brazil. At the LANXESS site of Porto Feliz, a cogeneration plant provides the site with electricity and steam. What makes it so special is that the plant is powered by a by-product of sugar production. This also enabled emissions at the site to be substantially reduced.
