The Council has approved Ecogas(external link) as the new long-term organics processor, following a multi-stage procurement process.
A 100% New Zealand partnership between Pioneer Energy and EcoStock, Ecogas currently operates an anaerobic digestion plant in the North Island. Ecogas has experience with managing organic waste with two existing North Island sites (Papakura Auckland and Reporoa).
This will be a whole new type of plant – fully enclosed, in an area zoned for this type of work. There will be speedy indoor processing with controls in place to effectively manage and contain any odour from the waste.
Unlike the plant at Bromley, it won’t do composting, and no waste will be kept outside. It’s a proven process that Ecogas is already running in the North Island, with no negative impacts on their neighbours. This technology is already used successfully in cities around the world, including London, Sydney and Edinburgh.
