Australian producers and marketers of power station ash formed the Ash Development Association of Australia (ADAA) with the objective of investigating and developing market opportunities for the use of these materials in various industry applications such as construction, agriculture and manufacturing.
While the principal output from coal combustion is energy, significant quantities of by-products in the form of CCP's are also produced. In life cycle terms, the opportunities to exploit the low energy embodied in CCP's such as fly ash, furnace bottom ash, boiler slags and cenospheres are extensive.
The combustion of pulverised coal in the furnace of a coal-fired power station boiler results in the production of a number of solid by-products, more accurately classified as CCP's (coal combustion products). This terminology reflects a more positive view and is in keeping with the concept of industrial ecology, being an approach that seeks to use one industry's by-product output as another industry's raw material inputs.

In June 2019, the Sydney City Council along with University of NSW and Wagners Concrete worked together to lay 15 metres of Geopolymer Concrete in a busy street of Sydney. The project was part of 7 years of research together with UNSW and the Cooperative Research Centre for Low Carbon Living, which saw the concrete laid to undergo 5 years of testing against regular concrete laid as a control.

The beneficial use of coal combustion products (CCPs) during 2018 resulted in 5.936 million tonnes or 47% being beneficially used, resulting in the conservation of; energy; finite natural resources, the reduction of carbon emissions through the recovery of CCPs being mineral by-product resources.

In the first trial of its kind, we’ve taken industrial waste from coal-fired power stations and steel manufacturing to create a new roadway. Working with researchers from the University of NSW, we’ve replaced a section of roadway on Wyndham Street in Alexandria to test the green concrete’s durability. Made from fly ash and blast furnace slag, geopolymer concrete is a sustainable blend of concrete and recycled materials.
