Woolworths Food Waste Diversion

Woolworths Food Waste Diversion is a Source Separated Organic Waste project operating as an aggregated initiative across various commercial Woolworths supermarket locations nationwide throughout Australia. It was registered in July 2016. Because it is an aggregated commercial waste diversion project spanning numerous urban and suburban supermarket facilities across the country, it does not occupy a single defined land area relative to a specific regional landmark or require a traditional property size metric.

The Source Separated Organic Waste methodology involves separating eligible organic materials (such as food waste) at the point of generation and diverting them from landfills. Standard requirements dictate that this waste must be transferred to specialized facilities for treatment, utilizing methods such as open windrow composting, enclosed composting, or anaerobic digestion. If anaerobic digestion is used, any biogas produced must be transferred to a combustion device and destroyed. This methodology prevents the harmful methane emissions that would normally occur if the organic waste were left to decay in a standard landfill environment.

Because the project is aggregated nationally across urban and commercial retail centres, regional land use is heavily commercial rather than agricultural. Consequently, natural environmental conditions like average rainfall classifications and specific soil types (such as basalt, clay, or sandy loam) are highly variable depending on the individual store location and are not a direct factor in the methodology's implementation.

This project aligns closely with Woolworths' broader corporate sustainability pledges. For instance, the supermarket chain has partnered with food rescue organizations like OzHarvest, Foodbank, and FareShare to divert over 55,000 tonnes of surplus food from landfills. The carbon project was supported by a Carbon Abatement Contract (CAC497655) initially awarded in November 2016. This contract has now been formally completed, having successfully delivered 88,675 carbon credits to the Commonwealth out of an originally committed 147,000 units.
