Product Innovation

As the world demands more sustainable products, less oil dependence, and fewer carbon emissions, we know that trees will become the solution to many global challenges. Products from fuel to plastic to clothing and cosmetics can be made from cellulose fibers. This tree-based future drives Weyerhaeuser's researchers and customers to new heights of innovation.

Textiles and construction are just two of the new markets using cellulose fibers in innovative ways to solve complex problems. Building a home involves hundreds of materials to create an environment that is protected from the elements, comfortable, and long-lasting. Cellulose fiber is used by the construction industry for a wide range of applications, including insulation and fiber cement.

Collaboration of Two Technology Leaders in Renewable Fibers

Weyerhaeuser signed a Memorandum of Understanding in July 2008 to work with Lenzing, the world market leader in cellulose staple fibers. The companies will work together on the development of novel lyocell-based nonwoven fabrics.

The objective of the collaboration is to develop a technology for the large-scale industrial production of an innovative and sustainable cellulose-based material for industrial and personal care applications. The technology will provide an alternative to petroleum-based materials in nonwoven products with raw materials based on renewable wood fiber.

The product is based on lyocell technology in which a solution of cellulose is processed directly and without intermediate process steps into a nonwoven fabric.
