Directed by Errol Webber, the film follows founder David Duong from the 1975 fall of Saigon, when he led 23 family members to sea, through a refugee camp in the Philippines to a 1979 arrival in San Francisco, where the family collected bottles and cardboard at night before founding CWS in Oakland in 1992. The company operates six Bay Area recycling facilities, processing roughly 1,000 tons weekly in Oakland and 1,300 tons weekly in San Jose, with more than three million tons managed over its history.

Oakland, Calif. – September 17, 2026 -- Vietnam Waste Solutions (VWS), the Vietnamese subsidiary of Oakland-based California Waste Solutions (CWS), has proposed a 50- to 60-megawatt waste-to-energy plant at its Da Phuoc Integrated Solid Waste Facility (DPI) outside Ho Chi Minh City, adding to roughly $200 million already invested in the site.

DPI, a 341-acre facility built in the mid-2000s to the U.S. Subtitle D standard, currently buries up to 6,500 tons of municipal solid waste daily -- about 2.4 million tons a year -- covering more than half of Ho Chi Minh City's household waste output of roughly 10,000 tons per day. VWS this year formally submitted the waste-to-energy proposal and is now moving through appraisal and permitting.
