Biosolids Flows (2015)

County-level snapshots showing where biosolids went in 2015. Use these figures to identify leverage points for circular systems: routing, beneficial use, treatment upgrades, and community-first siting.

We map the flows so planners, engineers, and community stewards can see where biosolids move and where circular pilots can safely intercept, upgrade, and reuse the material.

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."

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.
