After the Palisades and Eaton fires scorched entire neighborhoods, the Army Corps of Engineers set up operations to recycle concrete and metal from mostly fire-damaged homes. Tons of these everyday materials are washed where they're collected, loaded onto trucks, and sent to begin the recycling process. For example, metal is compacted and concrete is crushed, then shipped to recycling facilities before re-entering the supply chain for future uses. In the world of planet-warming emissions, making fresh concrete and steel are major contributors to climate change, and industry experts say recycling is a good way to rebuild more sustainably.
