Our Leadership

From Our CEO

The Recology rally cry is two simple words:  WASTE ZERO.

What do we mean by WASTE ZERO?  It means using resources wisely, generating waste only as necessary, and finding ways to use those waste products in ways that benefit the environment.  It means landfilling only those materials we haven’t yet figured out a use for.  We are passionate and committed to reducing waste and recycling everything we can.

Ingrained in our culture is our dedication and respect for each other as well as our community; our focus on customer services; and our genuine concern to lessen our impact on our environment.

We believe in giving back to both our community and the environment.

Our employee owners embrace this philosophy by volunteering in their communities and sharing innovative ideas that help us serve you better and become more sustainable.

As the largest employee-owned company in the industry, and as an innovative leader in resource recovery, we take pride in everything we do. Each of us can make a difference in the success of our company and of the world.
