Coal Combustion Product Utilisation
Coal combustion products produced from coal-fired power stations represent useful mineral sources of raw materials for a range of applications and products. Annually the Ash Development Association of Australia (ADAA) collects the production, sales and and utilisation statistics for coal combustion products (CCPs) and publsihes an Annual Production and Utilisation Survey Report.
Methodology
Annually members and non-members are invited to complete a survey for CCPs produced, sold and stored for the nominated reporting period. Information provided by members and non-members is collated, compared with other data sources, for verification purposes, and aggregated into national data set. No disaggrated (e.g State) data is published. The importation and exporting of CCPs are included using HS tarrif code data from ABS, however sources (regions) and destinations (locations) are not identified.
For members the information provides our industry with a map of production trends with a focus on where 'effective utilisation’ of CCPs is occurring.
Some important terms
'Effective utilisation' is the sale or utilisation of CCPs as recoverable mineral resources into a value added construction application that provides both commercial returns [revenue] return on investment or an economic return [avoided expense], and use is consistent with the criteria of ecologically sustainable development (EDS) principles.
The utilisation of CCPs in a variety of both high and low value add products helps to conserve natural resources such as sands and gravels. This reduces the environmental impact that would otherwise be caused by mining these natural resources. In addition, the need to construct additional storage facilities at the power stations can be deferred or even eliminated.
Annual Production and Utilisation Survey Report: 2022 - Summary
The beneficial use of coal combustion products (CCPs) during 2023 resulted in 4.8 million tonnes or 48% 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.
The survey results for CCP production and end uses for the period January to December 2023 discussed in this report are shown in Table 1. Over the survey period more than 74 million tonnes of thermal coal was consumed to generate vital energy to support the Australian economy. Some 10.2 million tonnes of all CCPs were produced with 48% being effectively utilised[1] within various civil and construction applications throughout Australia.
Total CCPs produced reduced slightly over the reporting period, with the longer-term trend continuing to decrease as planned closures out top 2050 come into effect. This decline is consistent with ongoing closures of coal fired power stations and reduced demand for thermal coal as an energy source, coupled with ongoing energy reforms, renewable energy targets (RET) and state government privatisation agenda for electricity over the past several years. For example since 2006 total megawatt available generation capacity has reduced 22% from 30,159 MW to 23,434 MW, with a further 10% reduction of generation capacity planned to occur in the next 3 years.
