Urban Waste

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.\r\n\r\nUrban 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.

本研究采用2013-2014年《南澳大利亚回收活动报告》（零废物南澳，Zero Waste SA，2015年）发布的全州范围内（源头分类）有机物资源回收数据，基于澳大利亚统计局（Australian Bureau of Statistics, ABS）SA4统计区域，分别估算了建筑与拆迁（Construction and Demolition, C&D）及商业与工业（Commercial and Industrial, C&I）领域的潜在生物质残余物体量。地方政府办公室收集的2014-2015年路边垃圾收集数据，则被用于推导城市生活垃圾（Municipal Solid Waste, MSW）相关数据集。
城市生活垃圾体量存在年度波动。未来的生物质数据集可考虑为生物质残余物体量设置取值区间，以更准确地反映年度产生体量的不确定性。同时需明确，源头分类有机残余物往往已被用于各类资源回收与再利用场景，例如覆盖物与堆肥产品的生产、厌氧发酵产能等。未来的数据集可对这类资源回收活动进行量化核算。
