LANXESS reduces greenhouse gas emissions

17th November 2017

• Specialty chemicals company has cut worldwide climate gas emissions (CO2e) by 13.8 million metric tons over 10 years • Specific climate gas emissions (CO2e) reduced by 53 percent • A further 25 percent reduction targeted by 2025 • State-of-the-art facilities and concepts to help achieve this

LANXESS has spared the environment 13,800,000 metric tons of gas emissions over the last decade, which is equivalent to the level of CO2 emitted by all cars registered in Cologne and Bonn (approximately 600,000) within the same period. The specialty chemicals company has made considerable headway in reducing the emissions that are currently a topic of discussion at the World Climate Change Conference. 

 

Since LANXESS was established, the company has been working continually to reduce harmful greenhouse gas emissions – and with considerable success: LANXESS production sites in Germany already meet the national reduction requirement set by the German Federal government for 2030. Between 2007 and 2016, the chemicals company saw an overall reduction of 53 percent in specific climate gas emissions (CO2e). 

 

Despite this positive assessment, the chemicals company is still working nonstop to reduce CO2 emissions, with the goal of achieving a further 25 percent reduction in specific greenhouse gas emissions between 2015 and 2025. LANXESS will meet this target by conducting routine reviews of production facilities and continuing to use innovative technologies.

 

“Environmental protection and economic growth are not mutually exclusive - LANXESS is contributing exceptionally efficient and effective production technologies in a concerted effort to achieve both,” explains Hubert Fink, member of the Board of Management of LANXESS AG.

 

Focus on efficient production

At its sites in Leverkusen and Krefeld-Uerdingen, Germany, and the Baytown site in the United States, for example, LANXESS has managed to feed a substantial amount of steam back into local integrated networks by consistently using process heat to generate steam (waste heat). 

 

Other examples include two new nitrous oxide reduction units (also known as LARA) at the adipic acid production site in Krefeld-Uerdingen. The first thermal nitrous oxide reduction unit – the first of its kind in Germany – began operation at the site in 1992, and since then it has accounted for emissions cuts of approximately 85 percent. The second LARA unit joined the network 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 degrees Celsius. The heat that this creates, in turn, generates steam that is fed into the site’s supply network. 

 

LANXESS is also reducing climate gas emissions at the Brazilian site of Porto Feliz thanks to its cogeneration plant. With an efficiency rate of up to 90 percent this highly efficient plant provides the LANXESS site with electricity and steam for use in the production of iron oxide pigments. Powered by bagasse, a fibrous by-product of sugar production, this power plant generates CO2-neutral energy. This cogeneration plant has made it possible for the company to reduce climate gas emissions substantially.

 

Exceptional performance in climate protection

 

LANXESS received further recognition in October 2017 for its commitment to promoting sustainability and reducing harmful emissions. The Cologne-based company was awarded top marks by the international climate protection initiative CDP (formerly known as the Carbon Disclosure Project), winning a spot in its Climate A List. The purpose of the list is to acknowledge the efforts made by companies to reduce emissions, minimize risks to the environment, and promote a low-emission economy. As a member of the Climate A List, LANXESS is among the top 5 percent of the thousands of companies that are rated by the initiative.
