October 9, 2019 - By 2030, the Lenzing Group aims to reduce its specific CO2 emissions per ton of manufactured pulp and fibers by 50%. By the year 2050, the Lenzing Group will no longer generate any net CO2 emissions.  Lenzing’s Management Board has now resolved to invest Euro 40 million to expand the production of the raw material sulfuric acid at the Lenzing site. The application of state-of-the-art technologies will further improve exhaust emission values, as the company says in the press release received by Lesprom Network.  Furthermore, the new facility will help further reduce the use of fossil fuels by generating steam which will, in turn, be converted into electricity. In this way, it will also support the energy self-sufficiency of the company’s operations in Lenzing. As a result, the production plant in Lenzing will reduce its annual CO2 emissions by 15,000 tons.  “On the basis of these investments, Lenzing is taking the next step in achieving its climate targets. At the same time, it will also reach a significantly higher level of autonomy with respect to a vital raw material,” states Stefan Doboczky, CEO of Lenzing.  The Lenzing Group is an international company that produces high- quality fibers and filaments from the renewable raw material wood with environmentally friendly and innovative technologies.
