The Interceptor system at Ballona Creek, LA, prevented 143,710 lbs of rubbish from reaching Santa Monica Bay in 2025, according to operator Ocean Cleanup. The solar-powered barge, which began its pilot in 2022, uses a floating barrier and conveyor belt to scoop waste into six dumpsters with a total capacity of roughly 20,000 lbs. Design and permitting cost $1.3 million, installation an additional $1.5 million, and annual maintenance runs to $650,000; the equipment is provided to LA County free of charge. Ocean Cleanup now plans two more Interceptor boats on the San Gabriel and Los Angeles rivers, part of a global fleet of 21 systems in 10 countries targeting the 1,000 rivers it says account for nearly 80% of ocean plastic emissions.
