Waste is not a word we use often. We use almost every portion – 95 percent – of every log when we make our products. Wood chips left over from making lumber are used to make pulp and paper. Logs too small for dimensional lumber are processed into engineered wood products such as oriented strand board. And, we generate a substantial amount of energy from wood residuals, also known as biomass fuels.

Many of our mills actively seek partners and customers who are able to use wood residuals in their products or processes, further reducing materials treated as waste. Obtaining maximum use of raw materials is a key consideration in process improvement, capital modifications, product changes and manufacturing operations.

In addition to these best practices relating to wood fiber, our manufacturing operations recycle other materials where possible. Combined, our efforts really add up — in 2012, we recycled or diverted from landfills more than 14 billion pounds of residuals and other waste.

Reduce Solid Waste Sent to Landfills by 10 Percent

Although most of our residual materials are reused for other purposes or recycled, we are committed to reducing the amount of waste we send to landfills. Our 2020 Sustainability Roadmap goal related to waste is to reduce the amount of material per ton of production that our manufacturing facilities send to landfills by 10 percent compared with 2010.

In 2012, we saw a 9 percent decrease in the amount of waste per ton of production sent to landfills. See our full residual management data below.

Reducing Waste During Homebuilding

Our real estate business, Weyerhaeuser Real Estate Company, and its five homebuilding subsidiaries, are constantly finding innovative ways to reduce construction waste as well. As an example, you won’t find a dumpster on a Quadrant Homes construction site. This business has eliminated combined dumpsters at construction sites and works with each vendor to manage waste. Many vendors are able to reduce or eliminate waste altogether, or find options for reuse or recycling. One vendor even found an alternative to the plastic sheeting used to cover soil after excavation—reusable hay blankets. The use of the hay blankets stopped the one-time use of the disposable plastic film, resulting in the equivalent of 12 football fields less material going to the landfill. For another example, watch this video of Pardee Homes creative solutions to reducing construction waste.

Residuals Management Data

We report on our total residual management (commonly known as “waste”) companywide. We also report on residual management per ton of production for our two manufacturing businesses, cellulose fibers and wood products, since this is a more accurate reflection of our waste management given increases and decreases in production.

  2. Includes recurring and nonrecurring hazardous waste.

  3. Data reflects performance of our current portfolio. In August 2008, we sold our containerboard, packaging and recycling business to International Paper. Operations involved in those transactions have been removed from historical data.

Hazardous Waste Generation Status

In 2012, 87 percent of our manufacturing facilities in the United States generated no hazardous waste or were in the U.S. Environmental Protection Agency's lowest-risk category for hazardous waste generation.
