Boeing Plant 2 became obsolete by 2010 after building B-17s and early 737s; demolition reused nearly 100,000 tons of crushed concrete as backfill on the Seattle site

In Seattle, the iconic Boeing Plant 2 has been dismantled, with a remarkable recycling initiative repurposing nearly 100,000 tons of concrete for on-site backfill. This significant step not only minimizes landfill waste but also lessens the dependence on new aggregate materials. Their efforts coincide with Boeing's ongoing environmental cleanup of the Duwamish River, signifying a commitment to sustainable industrial practices and extended pollution remediation.
