Designing sustainable, healthy and prosperous communities for a growing population is a challenge faced across the world. The origins of the food we eat are increasingly obscure and people in urban centres are often detached from food production. How can communities be designed to increase food security, minimise waste, build knowledge and skills, drive employment and enhance the natural environment? How can communities actively participate in the food economy of their region?
Yarrabilba in South East Queensland will host Australia’s first residential ‘circular food economy’ as part of this Food Agility project led by QUT and Lendlease. The project aims to develop a local food community based on circular economy principles. This means that the community’s food and green waste is collected and converted into compost. The compost can be used to support food production, putting seasonal, local food into the heart of communities. Food waste is diverted from landfill, reducing greenhouse gas emissions.
This project developed a community app to track food waste and offer incentives. Sensors were made from e-waste and monitored the quality of the compost via methane readings that push data into the app. Alerts tell the community when the compost and gardens require inputs.
These new technologies and research outcomes will be embedded into Lendlease’s development plans, which will see the population of Yarrabilba grow to 45,000 by 2041.
