Establishing Leaching Environmental Impact Assessment Tools in the development of a WA Framework for by-product re-use and classification
Total Grant Value
Large volumes of by-products are produced by mineral processing and related industries in Western Australia every year.
These materials could represent valuable commodities for construction, landfill and related purposes, but the lack of a formal regulatory process for assessing their environmental impacts prevents their commercial re-use.
This research successfully validated the LEAF (Leaching Environmental Assessment Framework) methodology developed by the US Environmental Protection Agency for use under Western Australian conditions to determine the long-term environmental impacts of industrial by-product re-use.
An initial database of local Western Australian soils and by-products has been developed for the LEAF modelling tool to allow robust predictions of the environmental impact of proposed or potential by-product uses.
Benefit to WA
The LEAF tools can provide greater confidence to industry, Government and the community regarding the environmental impacts of by-product use for specific applications in Western Australia.
This increased confidence will support commercial use of by-product materials In Western Australia, creating the potential for them to become a valuable resource in the local industrial landscape.
ChemCentre capability will allow expansion of this database as other soil types and materials are tested in the future.
