Partner Testimonials

"CES proved to be a valuable collaborative partner in our efforts to develop a corporate sustainability program. They were knowledgeable, innovative and experienced. The end product met our needs and expectations, and our sustainability program benefited greatly from their participation and insight."

Shawn Reiersgaard
Director of Environmental and Political Affairs, Tillamook County Creamery Association


"The Port and CES have a unique and collaborative  partnership that is mutually beneficial.  As a direct result of its partnership with CES, the Port has been able to develop and expand waste minimization strategies to its employees and tenants, maintain a strong leadership role in the industry, and  support and provide young professionals with an outlet for creative ideas.  I can’t see this being possible without the high quality, cost competitive services that CES brings to the mix.

“It’s always so much easier to complete sorts at PDX with CES – and we wouldn’t have been as successful implementing our own program had it not been for the help and training of the PDX team.”
