Used building materials from construction and demolition sites and home renovation projects make up about 40% of our waste. A lot of this material is reusable if it is handled properly, and you can save a lot of money and help our environment by buying used. Habitat for Humanity operates Reusable Building Materials Stores as fundraising projects in many communities. Contact them directly for information about donating or buying used building materials. Located at 4824 South Tacoma Way. (In Tacoma, call 779-8149). Also look under “Building Materials-Used" for Demolition and Recycling Companies that deal in used building materials in this area.
