South East Queensland Food Waste Trial Targets High-Density Housing and Holiday Accommodation

A new food waste recycling pilot in South East Queensland is targeting one of the more difficult parts of the household waste system: apartments, townhouses, retirement villages and short-stay accommodation.

The program, led by the Council of Mayors South East Queensland with participating local councils, is expected to divert more than 530 tonnes of food scraps from landfill. The material will instead be converted into useful outputs such as soil products, mulch and renewable energy. Sustainability Matters reported that the trial is equivalent to diverting around 100 garbage trucks of food waste from landfill.

The $4 million trial is funded by the Queensland Government and supported by researchers from Central Queensland University. It will test different approaches to food waste collection and processing across six pilots, including kitchen caddies with liners, in-home dehydrators, communal organics bins, on-site dehydration, off-site composting, anaerobic digestion and worm farm processing.

The focus on multi-unit dwellings is significant. Queensland’s population growth is increasing demand for medium and high-density housing, but these buildings often face constraints that detached houses do not. Space for bins can be limited, waste rooms may be shared by many residents, contamination risks can be higher, and short-stay visitors may have little familiarity with local recycling rules. The Queensland Government says the pilots are designed to study food waste separation behaviour, contamination, building design, facilities management, liner use, on-site processing, off-site processing and transport challenges in dense urban areas.

Six Pilots Across Different Building Types

The trial covers four council areas: Brisbane, Gold Coast, Sunshine Coast and Noosa. Brisbane City Council will run three pilots. One will test individual food waste dehydrators in a townhouse complex, with the dehydrated material used by residents or facility managers. Another will use kitchen caddies and liners in a high-density city complex, with collected food waste sent offsite for anaerobic digestion. A third Brisbane pilot will also use kitchen caddies and liners, but food scraps will be deposited into a large onsite dehydrator before being taken away for further processing.

The City of Gold Coast pilot will use kitchen caddies and liners in a high-density complex, with food waste deposited into a communal organics collection bin and processed offsite by composting. Sunshine Coast Council will test food waste collection in a retirement village, where residents will receive kitchen caddies and kerbside green lid bins collected weekly for composting. In Noosa, kitchen caddies will be used in short-stay accommodation at a resort and conference facility, with cleaning staff emptying the caddies into a designated organics bin. The material will initially be processed at a worm farm before being transferred for composting.

The first sites include an over-55s lifestyle resort on the Sunshine Coast, holiday accommodation in Noosa and three high-rise residential buildings on the Gold Coast. Brisbane City Council’s pilots are expected to begin later in 2026. The six pilots are anticipated to be completed in 2028.

Why Organics Matter for Landfill and Emissions

Food waste is a climate and resource issue as well as a waste management problem. When food scraps are sent to landfill, they decompose and produce methane, a powerful greenhouse gas. When recovered, the same material can be used to produce compost, mulch, biogas or electricity, depending on the processing pathway.

In South East Queensland, councils manage around 2.5 million tonnes of waste each year. According to Noosa Shire Council, only 35% of everyday household and small business waste is currently recycled, while 65% still goes to landfill. Organic waste makes up more than a third of domestic general waste in the region.

This creates a practical opportunity for local governments. Diverting food organics from landfill can extend landfill life, reduce emissions, improve resource recovery rates and support the production of soil improvement products for gardens, landscaping, agriculture and revegetation. It can also help councils manage rising waste costs, particularly where landfill levies make disposal more expensive.

The trial sits within broader Queensland policy goals. The Queensland Organics Strategy aims to halve food waste generation by 2030, divert 80% of organic material from landfill and achieve a minimum organics recycling rate of 70%. The Council of Mayors SEQ Waste Management Plan also aims to divert more than one million tonnes of waste from landfill annually by 2030.

Practical Lessons for Cities and Property Managers

The value of the trial is likely to come from operational evidence rather than the tonnage alone. Multi-unit buildings are often treated as a hard-to-serve segment in waste policy because they require cooperation between residents, body corporates, building managers, cleaners, waste contractors and local councils.

For property managers, the trial may provide clearer guidance on what infrastructure works best in different contexts. A retirement village with stable residents may need a different model from a high-rise apartment tower, and both may differ from a resort where guests are present for only a few nights. The Noosa pilot, for example, depends partly on cleaning staff transferring caddy contents into a shared organics bin, while other pilots rely more directly on resident participation.

For councils, the pilots could help answer questions about contamination, collection frequency, communications, liner choice, bin storage and whether on-site systems reduce transport needs enough to justify their energy use and management requirements. For waste processors, the program may provide better data on the quantity and quality of food waste available from dense housing and tourism accommodation.

For residents and visitors, the program is a reminder that food waste recovery systems need to be simple, visible and easy to use. Kitchen caddies, clear signage and well-managed shared bins can make participation easier, but behaviour change remains central. The trial’s research component should help identify where education, building design or service models make the biggest difference.

A Test Case for Circular Economy Waste Policy

South East Queensland’s population is projected to reach six million by 2046, with the region expected to be home to 75% of Queenslanders and one in six Australians. As the region grows, high-density living and visitor accommodation will become more important parts of the waste system.

That makes the food waste pilot more than a local recycling trial. It is a test of how fast-growing urban regions can adapt organics recovery systems to housing patterns that are becoming more common. If the program identifies models that are cost-effective, low-contamination and easy to scale, it could help inform wider rollout of food organics services across South East Queensland and beyond.

The challenge will be turning pilot results into repeatable systems. Success will depend on reliable collection, resident engagement, suitable processing capacity and practical rules for different building types. But the direction is clear: food scraps are increasingly being treated not as residual waste, but as a recoverable resource with value for soils, energy and emissions reduction.
