David Duong started his business 34 years ago with eight used collection trucks that he drove around Oakland. Today, he’s taking those Bay Area roots and channeling them into a $500 million environmental transformation miles away.
Founded in Oakland in 1992 by Duong, California Waste Solutions (CWS) offers municipal recycling services throughout the US. CWS also operates large-scale waste infrastructure in Vietnam through its subsidiary, Vietnam Waste Solutions (VWS).
In the US, CWS serves over 343,000 customers across Oakland and San Jose, using advanced recycling technology such as AI and optical sorting.
Through its subsidiary, the firm operates a large waste complex in Ho Chi Minh City. As per the latest announcements, CWS is investing over $500 million in a new waste-to-energy plant and a 1,760-hectare green industrial park to help Vietnam reach its 2050 goal.
“Investing heavily in the places you operate is one of the core differentiators of California Waste Solutions and its Vietnamese subsidiary. It’s not just something we do: it’s part of our core values,” said Duong, Founder and CEO of CWS.
CWS has 6 facilities in the Bay Area. The company is also modernizing its local operations with the installation of optical sorters, artificial intelligence scanning, and expanded curbside household battery collection.
But CWS’s footprint scale is different in Southeast Asia. VWS handles about 4,960–5,510 tons (4,500 to 5,000 metric tons) per day at the 128-hectare Da Phuoc Integrated Waste Treatment Complex in Ho Chi Minh City, about half of the city’s current output.
