The future processing of Christchurch’s kerbside organics is set to change with the Council approving the establishment of a new organics processing plant, Ōtautahi Christchurch Regional Organics Processing Facility. On Wednesday 6 December, the Council approved Ecogas as the new long-term organics processor, following a multi-stage procurement process. The facility will deliver a different system from the existing Organics Processing Plant (OPP) at Metro Place in Bromley through a fully enclosed operation and technology successfully used in cities around the world, including London, Sydney and Madrid. We’re continuing to empty the OPP site so there will be no stockpiling of material – which has been identified as the main source of odour.

The plan outlines odour mitigation measures that we have undertaken. As part of the transitional plan, we provided fortnightly updates to ECan with the progress made on the implementation of the proposed changes. Updates: What is the short-term option for managing kerbside organics? At Kate Valley, they’re using the compost as a capping material on the landfill. Capping the site is a long-term requirement, and using compost means they don’t need to transport topsoil there. Kate Valley Landfill is in the process of changing its consent to allow it to mature compost in outdoor rows, screen it, and then sell it to the market. Will organics continue to be processed at the Bromley site? When did the short-term option begin? Why can’t screening start at Kate Valley now? With the trucks coming in and out of the indoor processing hall, isn’t there a risk of odour escaping? What checks and balances will you have in place to ensure the OPP doesn’t produce odour? How much material would be shipped to Kate Valley for processing? Are you still be able to accept organics from Waimakariri District Council under this short-term option? How much is the short-term option costing ratepayers? How did you come up with the short-term option to partially process organics indoors at the Organics Processing Plant, with the second stage off-site? How long will the short-term option be operating? Independent external environmental specialist Pattle Delamore Partners has carried out odour monitoring at the Organics Processing Plant Composting garden waste started at the Bromley site. The plant started accepting and processing kerbside organics and food waste. Operational changes to mitigate odour are carried out by the Organics Processing Plant and EcoDrop Transfer Station. EcoDrop carries out an independent review of data. Environment Canterbury and Council considered how effective the operational changes have been in mitigating odour at the Organics Processing Plant and EcoDrop Transfer Station. Changes made by EcoCentral were found to be effective at reducing odour beyond the site boundary and Environment Canterbury deemed a resource consent was not required for the transfer station. Redevelopment options are considered for Organics Processing Plant. The upgrade would see the plant's technology upgraded to allow for the majority of the composting process to take place indoors. The Council approved a $22 million upgrade of the Organics Processing Plant. The upgrade involves redesigning and replacing the floors and doors of the plant’s 18 composting tunnels, replacing the shredder and improving the biofilter. The upgrades would ensure that all parts of the composting process would be fully enclosed, removing any potential odour or dust. The facility redevelopment option starts for the Organics Processing Plant. The final stage of the tender process for the redevelopment of the organics plant, the Request for Proposal (RFP), was released on April 27 2021. The RFP gives selected contractors eight weeks to produce a design for the plant and provides a quote on the cost to carry out the work. A preferred contractor was expected to be selected in June, with the contract finalised in July 2021. Transitional Management Plan developed with Living Earth outlining significant changes to operations at the Organics Processing Plant. Some of these changes included: The redevelopment of Bromley’s Organics Processing Plant was paused after the Council voted to investigate building a new facility at another location. Work is underway to look at options for potential new sites and technologies before a report is due back to Council in April 2022. The option of redeveloping the existing plant is also still being considered. The Council agreed in principle to relocate the organics processing operation to an alternative site. A report on the procurement process, for an alternative site, will be presented to Council in March 2023. Council approved moving to the final stage of the procurement process to find a permanent alternative to the Organics Processing Plant. The final stage of the procurement process will involve the six shortlisted suppliers submitting a competitive bid through a Request for Proposal (RFP) process. Council will make a decision on the preferred supplier in December 2023. Council decided to engage with the community and mana whenua on options for managing kerbside organics until a permanent solution is operational, including: Council indicated its preference was to end composting at the Organics Processing Plant as soon as reasonably, and practically, possible.

Resource consents allow people or organisations to do something that may have an effect on the environment, but this comes with conditions to protect the environment. Christchurch City Council holds many consents for its operations, some issued by Environment Canterbury (ECan). ECan monitors compliance of the resource consents it issues around the region. It conducts inspections to check consent holders are meeting their resource consent obligations. If there’s an issue, an ECan officer investigates to determine what actions should be taken, including enforcement. There is a range of enforcement actions that can be taken. Read more about Environment Canterbury's enforcement actions.(external link) The Organics Processing Plant is a Council-owned composting facility in Bromley that is operated under contract by Living Earth. The facility receives all the food and green waste collected in the kerbside green bins. The plant has been operating under Living Earth since 2009 and has helped divert over 400 thousand tonnes of organic material from landfill. View the Organics Processing Plant operational process (May 2023) [PDF, 466 KB] As part of our Transitional Plan in 2021, we installed a time-lapse camera at the Organics Processing Plant so you could see the reduction in outdoor compost.

The short-term option involves a two-step process, with the first indoor stage of processing happening at the current Organics Processing Plant in Bromley. The second stage is happening at Kate Valley Landfill.
We’ll continue to process organics at the plant in Bromley, with the first indoor stage of processing being done there and the second stage off-site. The first stage of processing involves mixing organics with garden waste, shredding the material, then moving the material into the composting tunnels. We’re confident that there’s minimal risk of offensive and objectionable odour from this new process.
This process was implemented in December 2023.
Transwaste, which operates the Kate Valley Landfill, requires a change to its resource consent to be able to carry out the second stage of the composting process. This is because that process is not currently included in the consent, although it is a permitted activity for a landfill. In the meantime, they’ll continue to use compost as a capping material at Kate Valley Landfill.
The processing hall will continue to operate with roller doors and under negative pressure with processing air treated through the biofilter before being discharged. The roller doors are designed to open and close quickly, multiples times a day, and will only be open when operationally required.
Living Earth will continue with their on-site odour monitoring and the Council will continue to engage external odour consultants Pattle Delamore Partners to conduct their proactive odour monitoring in the Bromley area. The Council will also monitor the site on an ongoing basis to ensure that no outside stockpiling of material is occurring.
Each year, we’ll transport about 40,000 tonnes of organic material to Kate Valley for the second stage of composting. This is about two thirds of the total amount of organics being processed in the first stage at the Organics Processing Plant (60,000 tonnes). During the first stage of processing, about a third of the organics are reduced due to material breakdown and moisture loss. This moisture is captured, passed through the biofilter and discharged.
Yes, organics from Waimakariri District Council (approximately 5000 tonnes per year) is still being processed.
It’s costing an additional estimated $276,000 per year. This is being funded through existing budgets, where possible.
The short-term option is the outcome of extensive consultation with the Bromley community, wider Christchurch residents and mana whenua. The desire to continue processing kerbside organics was strongly reflected in the consultation feedback. This option ensures kerbside organics continue to be processed until the long-term solution is fully operational. It also complies with our sustainability standards, and the risk of offensive and objectionable odour in the Bromley community through this option is also very low.
We’ll continue to process organics at the plant in Bromley until the new plant is operational. We expect the new plant to be up and running by late 2026.Odour monitoring reports
