The Lenzing Group, a producer of botanic fibres from wood, is expanding its environmental leadership commitment. As a leader in wood-based cellulosic fibres, Lenzing says it has ambition to help raising the bar in sustainability in the textiles and nonwovens industries. To fulfill this vision, Lenzing is investing more than 100 mn euro in sustainable manufacturing technologies and production facilities until 2022. In order to further extend the company’s environmental leadership, a major part of this investment will focus on closed loop production technologies for the expansion of the sulphur recovery systems.
