Auckland Council require a review of the construction and commissioning works for the Ecogas Reporoa Organics Processing Facility that has been developed, located between Taupō and Rotorua, New Zealand.

The facility is New Zealand’s first large-scale food waste-to-bioenergy facility, using advanced anaerobic digestion (AD) technology proven overseas, and is an exciting development to support more sustainable waste management.

The facility reduces food waste to landfill and converts this waste into renewable energy, biogas and nutrient rich biofertiliser on a large scale. The facility will process food waste from households and businesses in Auckland and has the capacity to process food waste from other council collections.


Our Sustainable Waste Management team based in Sydney have managed the project in collaboration with other technical disciplines to support the establishment of the facility which opened in October 2022.

Technical support was provided by the team based in Tauranga, along with the Acoustics and Vibration team based in Auckland, and the Process Engineering team based in the UK. Our team provided on-site supervision of the commissioning works, interacted with construction personnel on-site and are currently preparing a construction summary report.
