Waste management and the circular economy
Ensuring our cities are liveable, sustainable & productive requires major policy, regulatory & investment decisions relating to land-use and urban form, road, water, energy and waste infrastructure as well as investments in community open space for recreation and amenity.
Different approaches to management of waste have the potential to impact these major decisions and the community in different ways, including impacting long-term implications for urban design (including building standards & road design) and management of the energy & water cycle. For example, there may be opportunities to support the circular economy, reduce the waste management ‘footprint’ and achieve synergies across waste, wastewater and energy infrastructure, by adopting waste to energy via the wastewater system.
However, there are a range of factors that contribute to inefficient investment in the waste value chain and related infrastructure (e.g. dwelling, road, water & energy infrastructure):
- Different types of waste offer different opportunities and there is no ‘one size fits all’ solution
- Coordination challenges across council areas prevents efficient city-wide waste investment decisions
The substantial changes in the global and domestic waste markets, rising costs, sharpening environmental concerns including about new waste types, competing pressures on land use and shifting community expectations all mean that our current approach to waste management is likely to be insufficient.
Economics is critical to identifying the waste management strategy that generates the greatest benefit to the community, by enabling decision makers to:
- Analyse commercial and community value from investment: for example, analysing the value of an integrated utility providing waste, wastewater & energy services
- Understanding the impact of behaviour and incentives: for example, understanding the behavioural impacts of interventions aimed at increasing recycling (e.g. container deposit scheme)
- Evaluate the impacts of policy, regulation, infrastructure investment, pricing and funding – for example understanding who benefits and who pays for investment in integrated waste management
- Understand how economic value can be created through resilience decision making- for example, investigating the value of investing and pricing infrastructure that can respond to uncertain population growth & climate change.
