Ecogas gets consent for Christchurch

1 September 2025

Christchurch is a big step closer to having its household organic waste transformed into bioenergy and fertiliser with Environment Canterbury’s decision to grant Ecogas a resource consent for its proposed Ōtautahi Christchurch Regional Organics Processing Facility. 

Ecogas CEO Peter McClean welcomed the decision to grant the resource consent for its proposed facility in a Hornby industrial estate. 

Ecogas was awarded the contract from Christchurch City Council in December 2023 to provide an organics processing solution for kerbside and garden organics. 

The proposed Hornby facility combines anaerobic digestion (AD) technology and biomass processing to provide renewable energy and fertiliser products for Canterbury industry and agriculture. The project is on track to start processing organic waste from early 2027. 

Mr McClean said the facility has been designed to minimise any environmental impact, with all organic materials received and pre-processed within a fully enclosed building. Air from these areas is treated through a comprehensive ventilation and emissions control system.
