Table shows trends in organics recovery in states and territories reported in ROU surveys. ROU surveys do not include recovery of paper products, landfill biogas energy recovery, and energy recovery from timber, but do include recovery of some primary production wastes not included part of the scope of this report. This is why the total organics figures shown differ from those estimated in Table and Table . However, because the ROU surveys have used a consistent auditing method, they provide useful data for monitoring trends in organics management.

n/a = Not available. Data for Vic were not reported for the 2007/2008 year.
This shows that, over the six-year period from 2005/06 to 2010/11:
There have been fairly consistent organics recovery in the ACT and NSW and modest increases in WA and SA. Effective recovery systems were well established prior to 2005/06, and the major recovery operations were included in surveys from that period onwards.
There have been significant increases in recovery in Qld and Vic. To some extent, this reflects improved performance of recovery systems, but it may be partly due to improved data capture.
Nationally, the reported levels of recovered organics increased by 45%.
The ROU surveys gather information about the products made from recovered organics and the markets into which these are sold. Data are aggregated, so it is not possible to differentiate between products made from organic wastes from MSW, C&I and C&D sources and those from primary industry. The market data collected are measured by volume (m3) rather than by tonne.
summarises production and sales of materials from the ROU Survey for 2009/10, the last year for which this detailed information was available at the time of writing.

Figure and Figure show the breakdown of products made from recovered organics (excluding manures and direct application to land) and the markets into which the products are sold.

The figures above show:
Other than paper products and organics in landfill from which biogas energy is recovered, most recovered organics are converted into:
mulch (sales of 2.6 million m3/yr), mostly ‘raw’ mulch in the form of timber and bark-derived landscaping product
soil conditioner (sales of 1.4 million m3/yr.)
Almost 700,000 m3 /yr of processed recycled organics are used in the production of manufactured soils and a further and over 600,000 m3/yr is used in potting mixes.
Manure-derived products, organic fertilisers and direct land application of organics account for about 1.4 million m3/yr out of a total of 7.1 million m3/yr of recycled organic products.
Urban amenity markets are the main market for products, absorbing 56% or 3.2 million m3/yr of the total 5.7 million m3/yr of recycled organic products (excluding manure-derived products and direct application to land). Other markets for products are intensive agriculture (480,000 m3/yr or 8%), extensive agriculture (180,000 m3/yr or 3%) and rehabilitation and eco-remediation (280,000m3 or 5%).
About 28% of sales are of products not allocated to a specific market. It is likely most of these sales are to the urban amenity market, with a lesser amount to intensive agriculture. Urban amenity market probably account for 65–70% of annual sales of recycled organic products by volume.
At the time of the ROU survey, respondents had in the order of 3.3 million m3 on site. This is not surprising because many processes (such as composting) require materials to be processed for weeks. In addition, sales are typically seasonal and it is possible for sites to hold up to 50% annual inputs on site at some times of the year.
