State-wide data for (source separated) organics resource recovery reported by the South Australia Recycle Activity report 2013-14 (Zero Waste SA 2015) was used to estimate potential biomass residues by ABS SA4 Regions for C&D and C&I. Local Government kerbside collection data (2014-15) collected by the Office of Local Government was used to derive MSW data. Urban waste volumes may vary from year to year. Future biomass data sets could consider providing a range for these biomass residue volumes, which may better reflect the uncertainties in annual volumes that may be generated. It is also important to recognise that source separated organic residues will already be subject to some type of resource recovery and reuse (e.g. manufacture of mulch and compost products, anaerobic digestion for energy production). Future data sets could quantify this resource recovery activity.
