The Problem:
Can Anaerobic Digestion deliver renewable resource?
FOOD WASTE
• Variation in products, consistency and nutritional value
ANAEROBIC DIGESTION PLANT
• Safety, stability, practicality and sustainability
PLANT OUTPUTS
• Measurement, format, consistency, verification and benchmarking
Project Time Line
Plant Assembly : June 2016 Installation: October 2016
Commissioning: December 2016 Operation: January 2017
Continuous Plant Safety
Hazardous Area Classification
Design
Flow Control
Hazard Zoning
Monitoring
24/7
SMART Devices
Feedstock (Inwards) and Digestate (Outwards)
Feedstock: 8-15% Solids (Consistency of Soup / Fruit Smoothie)
Digestate: 1-2% Solids (Consistency of silty river water)

Telemetry
Remote Data Acquisition
Digestate Growing Trials
Plant growth rate for digestate was comparable to NPK fertiliser
Products of Value (Renewable Resources)
Methane – 32 MJ/ kg TS
CO2
Digestate (Fertiliser)
50% of NZ food waste 2.2
million GJ/year, energy for
43k homes
75% COD destruction
The Future of AD
315 Anaerobic Digestion plants in UK
7 Anaerobic Digestion plants in Australia
Worldwide more than 500 Anaerobic plants upgraded in 2016 (IEA Bioenergy)
Conclusion
Anaerobic digestion of NZ food waste can create renewable resources
