Product Health and Safety

We are committed to ensuring the public health aspects of our products in the marketplace. Our health and safety risk management policy states our commitment to "identify, understand and respond to public-health impacts of our operations and the use of our products and services."

As part of this commitment, we provide our customers with comprehensive Material and Safety Data Sheets in accordance with regulatory requirements and product stewardship needs. Health, safety, legal, regulatory and environmental issues are taken into account in our development of new products by identifying potential issues and mitigating or resolving any issues before commercializing a product. Additionally, all our facilities maintain policies that require all visitors, including customers, to have a safety orientation and wear proper safety gear before entering the operating portion of the facility.

Nanotechnology

Nanotechnology is the art and science of manipulating matter at the nanoscale (down to 1/100,000 of the width of a human hair) to create significantly new and unique materials, as well as improve the performance and economics of existing materials. Nanotechnology has many potential beneficial applications in the forest products industry.

Weyerhaeuser is engaged in examining the benefits of this new technology to help release the full potential of trees. The health, safety and environmental aspects of any potential nanotechnology application are considered across the stages of the potential product lifecycle. We are enabling the research and application of nanotechnology based on an approach that integrates economic, product and process opportunities with an understanding and consideration of environmental, health and safety elements.

Genetic Engineering

Weyerhaeuser operates seed orchards where we use the traditional techniques of selection and cross-pollination to produce seeds that grow superior trees. We grow seedlings in our own nurseries as well as purchase seedlings from others. We also use varietal seedlings, often referred to as clones. These varietal seedlings have genes that are all from the natural population of the species and, when mature, all pollen and seed produced by our varietal trees are entirely natural. Use of varietal seedlings is commonplace in the Southern Hemisphere and is increasing in the U.S.

Weyerhaeuser does not grow genetically engineered trees. Genetically engineered plants are regulated by law, and no genetically engineered forest tree has been approved for use in the countries where we operate. We support continued scientific research to understand the benefits and risks, and to ensure safeguards are in place if and when genetic engineering is used in commercial forestry.
