Biosolids are managed with extra caution. HVB does not support co-digestion of sewage sludge with food waste or other community organics.
Learn why and what pathways are considered safe.
How to read these charts
Each county image is a flow snapshot. The purpose isn't to memorize the diagram-it is to ask better questions faster.
Use the "4 questions" method
- What is the baseline- Where does biosolids go today (land application, landfill, incineration, export)-
- Where is value lost- Which flows are pure cost with high trucking miles or fragile permits-
- What is the constraint- Dewatering capacity, storage, seasonal land application windows, contamination, community acceptance-
- What is the smallest viable shift- "Move one arrow" with a pilot that can scale.
Systems rule: Don't start with "technology." Start with "stream + constraint + stakeholder."
This hub will eventually host an interactive map (counties + facilities + candidate sites). For now, use the county list to navigate.

Why this matters: Landfilling organics is a climate and cost problem. Reducing landfill routing often unlocks
grant narratives, methane reduction wins, and local soil value creation.
