Message from our CEO

David Duong

“For three decades, my family collected cardboard every night of the week to build CWS. Today, combined with our services in Vietnam, we serve more than 10 million customers weekly. The same dedication and commitment the company was founded upon is still at the core of everything we do.”


Our Service

We believe extraordinary care for our employees equals exceptional service to our customers and we strive for that each day

Our Values

As environmental ambassadors, we strive to preserve earth’s resources and prepare our communities for a sustainable future

Our Commitment

To be actively, engaged community-stewards by creating strategic community partnerships and effective public outreach


Our Mission

About us

Our mission is to minimize environmental impacts, eliminate waste, and promote recovery of those limited resources.

Reducing our ecological imprint makes economic and environmental sense, saving land and money communities otherwise use to dispose of waste in landfills.

We sell recycled materials to environmentally-sound, global markets where new products are made.

Preparing for the future means helping the communities we serve understand the value of green living and environmental sustainability.
