Report: Biogas production potential from municipal wastewater treatment facilities
Report of an investigation for Bioenergy Association of the waste-to-energy opportunities within New Zealand by Calibre, April 2018
This report describes opportunities to successfully
- Apply sustainable organic waste management practices and derive wastewater treatment cost savings in the process,
- Produce renewable (non-fossil) fuel (biogas) for heat and power generation,
- Attract new “zero carbon” manufacturing business activity and new jobs into NZ regions,
- Assist local businesses to meet their environmental compliance at lowest possible costs,
- Create new “zero carbon” business (employment) opportunities for new regional economic growth
- Produce in the process tradeable carbon certificates (greenhouse gas (GHG) emission reduction),
- Collect new revenue streams for local authorities which partially offset current asset operating costs,
- Increase waste water treatment plant energy efficiencies (energy cost are a major operating costs)
- Reduce waste water treatment plant biosolids (sludge) dewatering costs (another major operating cost)
- Reduce wastewater biosolids (sludge) disposal costs (another major operating cost)
- Improve the stabilisation grade and value of treatment plant sludge to allow unrestricted beneficial re-use.
