Finland-headed energy and forest industry technology provider Valmet Oyj has announced that it will deliver key process islands for Lenzing’s and Duratex’s joint venture named LD Celulose S.A. The new 500 000 tonnes-per-annum dissolving pulp mill is located in the cities of Indianópolis and Araguari in Minas Gerais state, Brazil. Valmet’s delivery includes a fiber line, a pulp drying and baling line, an evaporation plant, a white liquor plant, and a mill-wide automation system.
Valmet’s delivery is part of the recently announced Lenzing and Duratex joint venture investment of approximately US$1.3 billion in the 500,000 tonnes dissolving wood pulp mill where Austria-headed wood-based cellulosic fiber major Lenzing AG holds a 51 percent and Brazil-headed wood-based panel major Duratex S.A. a 49 percent stake in LD Celulose S.A. respectively.
Wood-based cellulosic fibers offer an important contribution to enhancing sustainability in the textile industry and this investment is in line with our growth strategy and a key milestone to structurally strengthen our cost leadership position. In planning the new production facility, particular importance was given to sustainability aspects. The plant will be among the most productive and energy-efficient mills in the world, states Stefan Doboczky, CEO of Lenzing Group.
The start-up of the new mill is planned for the first half of 2022 and will create approximately 8 000 direct jobs during the construction phase. When it is ready, LD Celulose S.A. will employ approximately 1 100 people to operate the industrial plant and the plantations that will supply it. The dissolving pulp is a key raw material for manufacturing Lenzing’s wood-based textile and speciality fibers.
LD Celulose S.A. will bring a positive socioeconomic impact throughout the region. We are working with the best environmental practices and with leading companies in the pulp industry, such as Valmet, said Luís Künzel, CEO of LD Celulose S.A.
