Construction & Demolition Waste: A Deep Dive

Buildings are the largest waste stream by weight — yet most of it is reusable material, not rubbish. Here is what actually gets recovered.

Construction and demolition (C&D) debris — concrete, brick, wood, gypsum, metal and more — makes up a huge share of total waste. Because it is bulky and separable, it is also one of the most recoverable streams.

What Gets Recovered

• Concrete & masonry — crushed into aggregate for roads and new building base.
• Metals — steel and copper pulled out and melted down (see our metal recycling guide).
• Wood — chipped for board, energy or mulch.
• Gypsum — wallboard reprocessed into new plasterboard.

Deconstruct, Don't Just Demolish

Careful deconstruction salvages doors, fixtures and timber for reuse, keeping far more value than a wrecking ball. Pair it with on-site sorting so clean streams stay clean.
