Impact tracking

We provide the necessary data and compliance reporting to verify your landfill diversion progress and environmental stewardship.

Biosolids management FAQs

Where do the collected biosolids go?

Once collected, we safely process and apply these organic materials to agricultural land or utilize anaerobic digestion facilities. This diverts them from landfills, where approximately 40% of U.S. biosolids currently end up.

Can you handle large-scale operations?

Yes. Our advanced technology and techniques are built for efficiency and scale.

How does land application benefit local farmers?

Applying biosolids to farmland improves soil health and increases crop production. It serves as a highly effective, natural alternative to chemical fertilizers, creating substantial cost savings for agricultural operations.

What is the impact on renewable energy?

Through our partnerships with anaerobic digestion facilities, the residuals we manage are converted into renewable electricity. This process averts fossil fuel consumption while enriching farmlands.

Restoring the earth through land reclamation

Mining activities leave behind severely degraded lands. For over 20 years, a major outcome of our organics management process has been the successful reclamation of these areas. We partner with landowners and government agencies — including the U.S. EPA on Superfund sites and the Abandoned Mine Land Reclamation Program — to reinvigorate spaces using tailored organic soil amendments and reseeding.

This cost-effective approach restores topsoil rapidly at a fraction of conventional fertilizer costs. To date, we have reclaimed and revegetated more than 3,000 acres, with half now returned to the public for hunting and recreation.
