David Duong is the founder and owner of California Waste Solutions (CWS) in the United States and Vietnam Waste Solutions (VWS) in Vietnam. He is a successful businessman who achieved his American dream by building a strong recycling and waste management business in California, while also investing in his parents home country, Vietnam. Both of his companies focus on environmental services like waste collection, recycling, and sustainability solutions. They help manage waste, recover useful materials, and support large-scale recycling projects. His businesses serve hundreds of thousands of homes in the Bay Area and millions of people in Vietnam, making them important players in promoting clean environments and modern recycling solutions across both regions.
David Duong’s Inspiring Journey from Refugee to Recycling Leader
David Duong is known as “The King of Trash,” a title he proudly carries, just like his father did in Vietnam. This name becomes even more meaningful in the documentary The King of Trash, which tells his life story—from being a refugee to becoming a leader in the recycling and sustainability industry.
The documentary shows the family’s journey as a powerful story of hard work, struggle, and success. It talks about their experience as immigrants, how they contributed to society and the important role recycling plays in protecting the environment.
It also highlights real progress in environmental work, such as the use of green technology and long-term partnerships. The story focuses on their efforts to serve communities on a large, international level.
In the film, David and his family share how they survived the fall of Saigon and moved to America to start a new life. They began by collecting recyclables from trash to earn money and slowly built their future. Over time, David started his own company, which grew from just eight used trucks into a well-known recycling business in the U.S. His first venture, CoGiDo, actually started with only one truck and $700.
From Struggles to Success: The Duong Family’s Journey in Recycling
When Saigon fell, the Duong family lost everything, including Jim Duong’s recycling business. They escaped Vietnam by boat and came to San Francisco where they lived in a small apartment. To survive, the family searched for recyclable items at night to earn money. These early struggles show how many immigrant families start with very hard and unseen work.
Later, Jim started another business and sold it in the late 1980s. After that, David took responsibility and started California Waste Solutions. Today, the company serves hundreds of thousands of customers in cities like Oakland and San Jose, playing an important role in waste management and environmental services.
David’s success did not come easily. He faced challenges and bias because he was an immigrant. His journey started with very little—just $700 and an old truck. Over time, his business grew and now handles around 1,000 tons of waste per week in Oakland and up to 1,300 tons per week in San Jose.
David Duong’s Work for a Cleaner Vietnam
David wanted to help make his parents’ home country, Vietnam, cleaner through recycling and sustainable projects. As one of the early overseas Vietnamese entrepreneurs to invest back in the country, he faced a lot of resistance and criticism. Instead of reacting with anger, he stayed calm, chose to forgive, and remained focused on his goal.
He worked hard to improve waste management in Ho Chi Minh City. By being open and transparent about his work, he helped change people’s negative views about large recycling projects.
Through Vietnam Waste Solutions, David introduced modern recycling and waste management methods to Vietnam. His work on large environmental projects has helped improve both operations and environmental standards in the region.
He played an important role in projects like the Da Phuoc Waste Management Facility and the Long An Green Environmental Technology Park. The Da Phuoc facility uses advanced systems like safe landfill design, waste treatment, gas control, and odor management. These improvements have helped reduce pollution and improve the quality of life for nearby communities.
Conclusion
David Duong’s story shows how hard work, strong determination, and clear goals can lead to success. He lost everything during the fall of Saigon and started a new life in the United States with very little money. Like many immigrant families, he faced many struggles. But instead of giving up, he and his family worked very hard, even collecting recyclables from trash, to slowly build a better life.
Over time, David turned these small beginnings into a successful recycling and waste management business that now serves hundreds of thousands of people in the U.S. His work helped grow California Waste Solutions into a well-known company and showed how important recycling and environmental services are for cities.
His story becomes even more special because he chose to give back to Vietnam. Even though he faced criticism and challenges, he stayed focused on improving waste management there. Through Vietnam Waste Solutions and big projects like Da Phuoc and Long An, he has helped improve the environment and living conditions for many people.
In the end, David Duong’s journey is not just about business success. It is a story of never giving up, having a purpose, and making a real difference. His work shows how one person can create positive change in different parts of the world, helping both people and the environment.
