LA Rivers Get Trash-Eating Barges Before 2028 Olympics

Los Angeles rivers are getting a serious cleanup thanks to floating barges that eat trash for breakfast, and the timing couldn't be better with the 2028 Olympics on the horizon.

Two LA districts faced a massive challenge: thousands of pounds of garbage flowing down the LA and San Gabriel rivers straight to their famous beaches. So they called in Boyan Slat, the inventor behind The Ocean Cleanup, whose river-cleaning device called the Interceptor is already proving it works.

The bulbous white barge sits quietly in Ballona Creek near Marina Del Rey until rain washes trash from neighborhoods like Venice, Beverly Hills, and Santa Monica downstream. Then it springs into action. A boom and net funnel garbage to a central mouth where a conveyor belt pulls debris out and dumps it into six bins on the barge.

Since 2022, the Ballona Creek Interceptor has collected more than 200 tons of trash. That's 28,000 pounds every single year that never reached the ocean.

Now Seal Beach City Councilmember Joe Kalmick and state assemblymember Diane Dixon want the same success for the San Gabriel River. They formed a working group and commissioned a feasibility study to bring another barge to their waterways.

James Patterson, who heads Ocean Cleanup's LA operations, says each barge gets customized for its location. The LA and San Gabriel rivers present unique challenges because of the sheer volume of trash rushing through during storms.

The Ripple Effect

Slat originally designed the Interceptor for the world's 100 most polluting rivers in developing countries. Now his invention is helping wealthy California communities tackle their own waste problems before it becomes ocean pollution.

Long Beach will host Olympic rowing and open swimming events in 2028. Mayor Rex Richardson wants visitors to see the city's coastline at its absolute best. The new barge for San Gabriel River costs several million dollars, but officials consider it an investment in both the environment and the city's global reputation.

Every piece of plastic, every bottle, every wrapper caught by these barges is one less item threatening marine life or washing up on beaches where Olympic athletes will compete.

The cleanup effort shows what's possible when cities invest in proven technology and act before problems get worse instead of after.
