Whether you’re a construction professional or just building a backyard patio, check out ResourceStLouis.org, a website that fosters sustainable building practices and an online Materials Exchange designed to keep usable construction materials out of landfills. The latter is a great place to find inexpensive, reusable construction materials from demolitions and construction projects, all posted in a searchable database. Here are a few items you could pick up:

• 40 4′ x 8′ sheets of fiber rock drywall for $10 a sheet
• 70 acoustic ceiling tiles for $1 each
• a solid-core metal exterior door for $5.

Kudos to founders David Bertorelli and John Prater of Enterprise Rent-A-Car and the executive board of ReSource St. Louis!
