Summerhill Waste Management Centre is proposing to expand its operations to include an organics processing facility. This will be a fully-contained composting facility, which includes receiving, composting, maturation, and storage areas. The proposed facility will use new technology to process food and garden organic waste into compost that can be used for landscaping, in agriculture and site rehabilitation.

Summerhill Waste Management Centre is a solid waste landfill managed by City of Newcastle. The site is licensed by the NSW Environment Protection Authority (EPA) to receive 'General Solid Waste (Putrescible and Non-putrescible) and Special Waste'. The facility has approval to receive up to 362,000 tonnes of waste per annum. Organic material is included within this tonnage and is already managed on site.

The facility design contains the following elements:

• Dedicated spaces to sequentially receive, process and dispatch organics waste in a completely contained facility.
• Processing equipment that includes the initial intensive composting phase for 14 days, followed by 28 days of aerated maturation and another 20 days of passive maturation.
• An active odour control system ensures that air is continuously drawn from the facility buildings to keep it under a constant state of negative air pressure. Chemical scrubbers and a biofilter are installed on the exhaust to mitigate odour produced within the facility before it is discharged

The following works also need to be carried out to prepare the site for the Organics Processing Facility:

• The site of the Organics Processing Facility has existing organics and recycling processing activities carried out upon it. These activities need to be relocated to other parts of the site.
• The site will be cleared and decontaminated. Mine grouting will be undertaken to ensure the safety of the ground beneath the structure.
• Bulk earthworks will be carried out to install the finished levels and to install stormwater controls.

A summary of the works required to enable the Organics Facility can be found on the information sheet here.

• Currently food waste generated in Newcastle is disposed to landfill. Both CN and the community share the desire to reduce waste to landfill and increase resource recovery. The organic processing facility is part of how we can achieve that.
• The organics processing facility will allow us to collect and process food organics in addition to garden organics.
• Collecting food waste will divert approximately 6,000 tonnes of waste from landfill each year.
• Once completed, the facility will be capable of processing 50,000 tonnes of organic waste each year, creating an opportunity to reduce waste and encourage more sustainable resource management locally.
• By diverting waste from landfill and processing food and garden material from households and businesses in the Local Government Area, the facility will be contributing to our goal of net zero emissions from its operations by 2030.
• We are committed to meeting future infrastructure and service needs in line with NSW Government’s Waste and Sustainable Materials Strategy 2041 which sets a target of halving the amount of organics waste sent to landfill by 2030.

It is proposed that our kerbside collection vehicles will collect food and garden organic waste from households via the green lid bin and deliver it to the facility via the existing site entrance at Summerhill Waste Management Centre.

The waste material would be unloaded within the enclosed facility, where it would undergo ‘pre-treatment’, to remove unsuitable material from the organic waste stream. The organic waste is then transferred to sealed tunnels for 14 days of intensive composting.

From here, the immature compost is transferred to aerated maturation bays for 28 days.

Once the compost has matured it is screened, with large or inorganic particles being separated from smaller ones.

The compost is transferred to passive maturation bays where it undergoes final quality testing before storage / dispatch.

Currently Summerhill Waste Management Centre is only able to sort and shred garden organic material, which is then transported off site for further processing.

The proposed organics processing facility will be able to process food waste as well as garden organics. This significantly increases our ability to reduce the amount of the region’s organic waste that ends up in landfill.

Organics processing helps us extend the life of a landfill site by reducing the amount of material that ends up in the landfill and reduces the amount of greenhouse gases emitted by the landfill.

The State Government has mandated that all local governments introduce collection and processing of food and garden organic waste by 2030, and major commercial generators by 2025.

A Development Application for the construction and operation of an Organics Processing Facility approved on 17 September 2024 by the Hunter and Central Coast Joint Planning Panel. The facility proposed under this DA would have the capacity to process 50,000 tonnes per annum of food and garden organics (FOGO).

Now that this option is confirmed as viable from a planning approvals perspective, City of Newcastle will conduct a broader assessment of current options on how to manage the collection and processing of FOGO for Newcastle residents as part of our commitment to implement a service by 2030 under the NSW Waste Strategy.

The proposed organics processing facility will reduce the amount of the region’s waste that ends up in landfill.

Organics processing helps us extend the life of a landfill site by reducing the amount of material that ends up in the landfill and reduces the amount of greenhouse gases emitted by the landfill.

The organics processing facility is being designed to be an entirely enclosed facility that will contain noise and odour. The facility is a single-story building, located within the existing Summerhill Waste Management Centre. The facility is unlikely to be visible from nearby residential streets. An active odour control system ensures that air is continuously drawn from the facility buildings to keep it under a constant state of negative pressure. Air pollution control devices are installed on the exhaust to reduce the odour before it is discharged meeting environmental regulations.

The facility will be owned and operated by City of Newcastle. It is expected that approximately 180 jobs will be generated throughout construction and between 8 and 10 jobs during ongoing operation.

There is currently no proposal to increase rates.

At this stage Council has not made a decision about distribution of the compost from the facility.

The timeframe around the kerbside collection of food organics and garden organics is currently being considered by Council.

The technology proposed has been developed by Waste Treatment Technologies (WTT) based in the Netherlands. WTT have built over 125 facilities across the globe utilising this technology. The WTT technology has been used to develop organics processing facilities in NSW and Victoria.

Truck activity is expected to remain the same as it is currently, with the new facility utilising the existing entrance and exit routes to Summerhill Waste Management Centre, off Minmi Road.

The organics processing facility will accept source-separated food and garden organics wastes collected in dedicated kerbside collection bins and process them into compost that meets both Australian standard for composts, soil conditioners and mulches and all relevant NSW EPA regulations.

Conversion of waste into compost is a beneficial waste minimisation technique as it avoids disposal of the food and garden organic wastes to landfill, reducing the impacts that landfills have on the environment.

Communities can achieve major environmental benefits by separating and recycling organic materials. Proper waste management helps improve air and water quality as well as reduces greenhouse gas emissions. It helps in reducing pollution and energy consumption associated with manufacturing new materials.

City of Newcastle is committed to meeting future infrastructure and service needs in line with the NSW Government’s Waste and Sustainable Materials Strategy 2041 which will come into effect in July 2022.
