The Division of Water Reclamation takes treated wastewater solids, yard debris, and wood chips and transforms it into a nutrient‑rich, Class A compost through a natural process. As part of Columbus’s 100% Beneficial Reuse Program, biosolids are either composted, land‑applied, digested, or used to regenerate forests and farms across Ohio, never dumped or burned. That means your unwanted yard waste and biosolids are turned into healthy soil boosters, enhancing gardens, farms, and restoration sites. Com‑Til closes the loop, returning nutrients back into the earth in a truly circular, sustainable system.
