Focus energy saving
Pulp and fiber production is energy intensive. Energy conservation has a long tradition in the Lenzing Group, for economic and ecological reasons. Many of the ongoing optimization efforts are aimed at cutting energy use. All production sites of the Lenzing Group have a secure high-tech energy supply based either on their own highly efficient power stations or on close cooperation with local power producers.

Share of Biogenic Energy Sources Far Above the Average
The energy sources range from the thermal utilization of the remaining wood components that are not used for material purposes to gas and other fossil fuels.
Pulp production at the Paskov site is nearly self-sufficient in terms of energy because of the use of #wood as a raw material. The Lenzing facility generates a surplus of energy in pulp production and uses that surplus in fiber production in the form of heat (steam) and electricity.
The Lenzing Group uses a much greater proportion of biogenic energy sources in relation to total worldwide energy consumption than the average. More than half of its required energy is derived from renewable fuels.
Energy supply of individual production sites
The energy supply of the individual production locations is heavily dependent on the local conditions. The pulp production sites in Lenzing, Austria, and Paskov, Czech Republic, both have an exceptionally high percentage of biogenic fuels (about 90%).
The production sites for the specialty fiber TENCEL® – Heiligenkreuz in Austria, Grimsby in the United Kingdom and Mobile in Alabama, USA – use natural gas to cover most and in some cases all of their energy requirements.
By contrast, the two sites at Purwakarta, Indonesia, and at Nanjing, China, are largely dependent on coal as an energy source.
Oil plays almost no role at all in the Lenzing Group unlike in worldwide energy consumption.
