  1. Local Government Waste Summit 2006 Total Cost Approach for Waste Management Christine Wardle 10 February 2006

  2. Why total cost approach • Understand all costs arising from undertaking activity • Reflect economic value invested by community • Apply ‘user pays’ approach to investment • Incorporate financial incentives for waste avoidance • Provide funding flexibility to meet changing circumstances • Can save the community money through reduced costs

  3. Total kerbside collection costs • Replacement bins, vehicles • Maintenance & repairs • Marketing costs • MRF/depot - land, approvals, D&C • Plant & equipment • Material handling, specifications • Risk management, insurances • Site management plan • Public place recycling infrastructure • Disposal fees • Emergency arrangements • Contaminant disposal costs • Baseline investigations, audits • Tender costs • Administration costs • Legal, contract costs • OH&S, training, PPE • Fuel, utilities • Receptacles • Collection vehicles • Greenhouse gas emissions • Education & advertising • Data management • Road use, community amenity costs

  4. Total landfill costs • Land acquisition • Planning & design • Approvals • Infrastructure (& supplementary) • On-going cell development • Operation & management • Administration • Financing cost • Reporting • Off-site contamination & pollution • Greenhouse gas emissions • Loss of productive use of land • Loss of community amenity • Site rehabilitation • Infrastructure removal • Post-closure monitoring/management • Replacement site

  5. Rural landfill cost analysis • LGA + EPA, Office of Local Govt, Zero Waste SA • 6 rural landfills (S, M, L) (B-, B+) • Council, EPA co-operation • Site inspections, licences, Council data • 4 cost models • current costs, licence compliance costs, EPA cost model, draft revised landfill guidelines

  6. Methodology issues • Accrual accounting or cash accounting • Depreciation – rate, discounted • Present value / future value calculations • Interest rates • Amortisation period • Obsolescence (landfill lifespan) • Contractual arrangements

  7. Costing issues….. • Define inputs & assumptions • Total costs, net costs & unit rates • Units - tonnes or cubic metres • Accuracy of data • estimate / measure, loose / compacted volumes • recycled / deposited in landfill • landfill airspace, lifespan • cover, compaction rate

  8. …..more costing issues • Contractual arrangements • commercial / community • scope • Site-specific factors • hydrogeological conditions • local materials • Council / commercial services • Future liability

  9. Project findings • Small sample size • Large unit cost of operating small landfills • Little recovery of costs • No large costs to comply with licence • Biggest impact of guideline implementation on medium- sized landfills
