City of Bellingham Resource Recovery Project Update

The City of Bellingham is implementing a resource recovery project that focuses on moving away from incineration towards producing Class A biosolids through anaerobic digestion. This project not only benefits the environment by reducing GHG emissions but also improves soil health and community integration. The project includes a demonstration garden showcasing biosolids in action and plans for facility expansion and design. Climate action goals and cost estimates are also addressed in the update.

  1. City of BellinghamResource Recovery Project Update January 28, 2019

  2. Solids Stream Project Drivers There isn’t a “do nothing” option to address these needs.

  3. Public outreach demonstrated support for moving away from incineration • TBL+ process supported • Interest in moving to a Class A biosolids product

  4. Phase 1 – Identified Class A product for local beneficial reuse

  5. Phase 2 – Select Digestion-based approach to produce Class A and Biogas use

  6. Phase 2 - Preliminary TBL+ Results: Class A Digestion and Pipeline Injection

  7. Anaerobic digestion-based solution benefits Incineration GHG Emissions Digestion* GHG Savings

  8. A demonstration garden at Post Point showcases biosolids at work • Provides nutrients • Improves soil health/tilth • Sequesters carbon

  9. Beyond a new solids treatment system, the project includes integrating other City functions • Solids treatment • Energy recovery • Ancillary systems • Integrated Ops/ Community Building Example of a community education and environmental outreach center (LOTT Alliance, Olympia, WA)

  10. Planning Level Cost Estimate Summary

  11. Potential Rate Impacts • $24-$30/ERU/month on average • Preliminary Analysis • Based on Equivalent Residential Unit • Rates vary across customer classes • Additional work needed for impacts to customers and affordability metric
