Give surplus materials a second life instead of a landfill destiny.
Construction waste doesn’t have to be inevitable. Each year the U.S. construction sector discards nearly 600 million tons of material (EPA, 2023). CircularBuild makes it simple for donors with high-quality excess to route those supplies to neighborhood repair crews, college design-build clubs, and humanitarian teams who need them quickly.
From campus makerspaces to Engineers Without Borders projects, we exist to close the loop between jobsite surplus and world-changing ideas.
Wood & lumber
Dimensional lumber, sheathing, and trim make up 40% of residential waste. Knots or odd lengths can still frame sheds, furniture, and formwork when matched with the right crew.
Metals
Steel and aluminum offcuts carry energy-intensive embodied carbon. Keeping them in use avoids the emissions tied to smelting and transport.
Finishes & fixtures
Surplus tile, windows, flooring, and cabinetry help nonprofits stretch budgets and keep high-value items from salvage yards.
Why circular sourcing matters
- Cut tipping fees: Disposal costs keep climbing. Listing materials is free and keeps resources in circulation.
- Keep crews moving: Builders can source hard-to-find items locally instead of waiting on long supply chains.
- Empower community impact: Student design-build clubs, humanitarian nonprofits, and grassroots repair teams gain access to safe, reliable supplies without the cost of virgin sourcing.
How CircularBuild works
- List surplus material: Donors detail availability, pickup windows, and terms.
- Search smarter: Builders filter by specs or scan an interactive map to see what’s nearby.
- Chat & coordinate: In-app messaging keeps communication organized until the transfer is complete.
