Arial Bold 17 point Arial Bold 17 point Arial 14 title area Food Waste Pilots – the story so far Justin Lang, Program Manager – Local Government, ZWSA LGA / WMA Breakfast 17 November 2008
Once upon a time in a land far away… • There lived a princes trapped in a kitchen… • People in her village had no idea of what to put in their GO bin • But then along came the GO contamination wkg grp
Source separated food organics • Burnside Trial • September 2005 to April 2006 • Green organics collection, monthly to fortnightly • food organics popular • achieved 64.6% kerbside diversion • potential for greater diversion from landfill (GO Bin ownership, increase participation)
Source separated food organics • Business Case (undertaken by John Comrie ‘06) suggests • costs $15-16/hh/annum to add food waste to 3 bin system • reduces to marginal saving if waste collected fortnightly • http://www.zerowaste.sa.gov.au/pdf/reports/food_waste_collection_business_case.pdf • Further business case to be undertaken – from pilots.
Why Pilots? • To identify: • Costs and savings (compared with existing 3 bin system) • Diversion from landfill & participation • Yields and capacity in each kerbside bin
Why Pilots? • To identify: • Contamination rates (recycling and organic bins) • Effectiveness of communication material • Community attitudes

After 7 Days Testing decomposition: 6 Samples
After 28 Days Testing decomposition: 6 Samples
Audits - Complex and critical • Councils nominate areas / demographics; • Numerous samples (seven councils had 2 samples, 1 x 3, 1 x 4, 1 x 6); • Visual analysis – dwelling type, chronological list and digital photos, notes on contents, capacity analysis; • 3 streams, 100 bins, presentation rates; • Audit facilities & checklist for Councils.
Kerbside Audits • Demographics (population, no. per h/hold, dwlg type) • Traditional dwelling • Semi-detached • Maisonette (1950’s SAHT) • MUD (Units) • Row dwellings/townhouse • Rural Living (over 3,000m2) Where 5% or more • Representative versus random sampling • Revisit & seasonal issues
Kerbside Audits • Bin condition (potential) • Contamination item count and weight • Incidence of contamination • Composition analysis (site specific / truck level) • Presentation ratesWaste …………….. 95% Recyclables ……… 86% Green Organics …. 52%
Opportunities • Initial support from Zero Waste SA to implement systems to divert more compostable material. To learn together, and share findings; • In a pilot, potential to: • review participation, diversion, contamination, • bin ownership, rate of uptake* • satisfaction levels, • assess economies of full-scale implementation, • capacities (bin and collection rounds); Image area
Nuances of a system – and management • Specific attributes of a successful system (weekly versus fortnightly), • Presentation of residual bins - collection with alternating bins (green organics versus recyclables); • Assessment of increased diversion (incl. recyclables); • Extent, severity and incidence of contamination; • Three strikes policy – keeping recyclables and green organics clean. • Options for large households – user pays for extra MGB? Image area
Cost sharing framework for pilot Zero Waste SA is funding: • Kitchen receptacles/bins for food waste • Compostable bags (150 bags / household) • Kerbside audits – all three streams (2 per council) & report • Market research - survey (representative sample / pilot) & report • Development of template communication materials
Cost sharing framework for pilot Councils are responsible for: • Communication with residents in pilot areas • Negotiating with collection contractors and processors • And are funding: • Production of communication materials • Delivery of containers (and compostable bags) to households
Pilot brochures… • Key messages : • Frequency of collections • Place material in GO Bin • 50% of residual stream is organic • System will help divert up to 75% of residential waste • Uses images, icons, KISS • As easy as one, two, three…
Local Government feedback • Performance criteria (contract conditions): • Performance based: success thresholds and intervention levels; • Intention to maintain pilots (for up to 2 years) with potential to expand with further support; • Repayment events; • Feedback on containers; • Communication material – development of clear, common messages and enjoy efficiencies; Image area
Fortnightly Waste - Issues • Need for a trial of fortnightly 140L waste bin • Perception – not enough capacity in waste bin • Expected to force more organics and recyclables into other bins (hence improved diversion from landfill) • Effect on contamination - green organics and dry recyclables?
Conclusion • The 10 pilots will contribute to a broader body of work: • Audits: systems, diversion, contamination, yields • Market research: user satisfaction • Cost/benefit analysis of each system • Capacity analysis (visual analysis by audits), tonnes per truck • Option later for Councils to change systems with support • Following final assessment, reports will be available at www.zerowaste.sa.gov.au
