David Duong (born Dương Tử Trung) is a Vietnamese-American entrepreneur, recycling industry pioneer, and philanthropist known for modernizing waste-management infrastructure in both the United States and Vietnam. As the Chief Executive Officer of California Waste Solutions (CWS) and Chairman of Vietnam Waste Solutions (VWS), Duong has spent over three decades advancing sustainable technologies, clean-energy solutions, and large-scale integrated recycling systems.

From fleeing Vietnam as a refugee to building one of Northern California’s largest recycling companies, Duong’s life trajectory has made him one of the most influential figures in the global recycling and environmental-technology sector. His work connects Vietnamese-American business leadership with U.S.–Vietnam economic cooperation, shaping policy, infrastructure, and environmental education across borders.

Early Life: From Refugee to Innovator

Born in Saigon, South Vietnam, David Duong grew up in a family deeply involved in the paper and recycling trade. After the fall of Saigon in 1975, his family escaped Vietnam by boat and resettled in San Francisco.

In their early years in America, Duong and his family survived by collecting paper, cardboard, and recyclables on the streets—work that later became the foundation for a multimillion-dollar environmental empire. The experience built his resilience, business instincts, and lifelong commitment to waste reduction.

Career & Leadership

California Waste Solutions (CWS)

In 1992, Duong founded California Waste Solutions, which has since become one of the largest recycling companies in Northern California.

Under his leadership, CWS:

  • Operates major materials recovery facilities in Oakland and San Jose
  • Manages municipal recycling contracts serving millions of residents
  • Processes thousands of tons of recyclables daily
  • Employs hundreds of workers across California
  • Implements U.S.-standard advanced sorting, baling, and waste-diversion technologies

CWS is widely recognized for improving recycling efficiency, expanding green jobs, and advancing California’s environmental sustainability goals.

Vietnam Waste Solutions (VWS)

In 2005, Duong expanded his environmental mission to Vietnam by founding Vietnam Waste Solutions (VWS).

VWS developed the Đa Phước Integrated Waste Management Facility in Ho Chi Minh City—the first large-scale, privately financed, fully integrated waste-treatment complex in Vietnam.

The 128-hectare facility includes:

  • Recycling and sorting centers
  • Composting systems
  • Sanitary landfill operations
  • Waste-to-energy research
  • Renewable-energy development programs

VWS has since announced a major smart, waste-to-energy facility in Long An Province, a next-generation project designed to support Vietnam’s growing urban environmental needs.

Chairman of the Vietnamese American Business Association (VABA)

Duong also serves as Chairman of VABA, a global network of more than 2,000 Vietnamese-American entrepreneurs across 12 U.S. states and 8 countries.

VABA promotes:

  • U.S.–Vietnam trade and investment
  • Entrepreneurship development
  • Business policy advocacy
  • Startup mentorship through its Pitch Perfect competition
  • Networking between the diaspora and Vietnam’s emerging markets

His leadership has positioned VABA as a major bridge between the two economies.

Philanthropy & Community Work

David Duong’s philanthropic initiatives span the U.S. and Vietnam and include:

  • Educational scholarships for low-income and immigrant students
  • Disaster-relief support in both countries
  • Funding for environmental-education campaigns
  • Humanitarian projects for vulnerable communities
  • Support for Vietnamese cultural and youth organizations
  • Charitable programs linked to CWS and VWS operations

His family foundation regularly donates to hospitals, schools, and community centers.

Recognition & Global Influence

Duong has been honored multiple times for his environmental and humanitarian work:

  • City of Oakland commendations for sustainability
  • San Jose City Council recognition for green-job creation
  • Awards from Vietnam’s Ministry of Natural Resources and Environment
  • Featured in the 2024 documentary film The King of Trash, directed by Errol Webber
  • Recognized as one of the key figures transforming waste management in Southeast Asia

His story is often cited as a prime example of refugee success, environmental leadership, and global entrepreneurship.

Personal Life

David Duong resides in the San Francisco Bay Area with his family. He regularly travels between the United States and Vietnam to oversee business operations and philanthropic work. Despite achieving major business success, Duong continues to emphasize humility, community service, and environmental responsibility.

Legacy & Impact

Duong’s three-decade career reflects a rare blend of entrepreneurship, sustainability, and cross-cultural leadership. By introducing modern American recycling and waste-management practices to Vietnam, he has reshaped environmental thinking in both regions.

His companies continue to lead in:

  • Integrated waste solutions
  • Recycling innovation
  • Clean-energy research
  • Workforce development
  • Climate-conscious infrastructure

David Duong’s journey—from a refugee collecting cardboard to a global environmental industry leader—stands as a landmark success story in the Vietnamese diaspora and in the world’s transition toward sustainable development.
