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. 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 industries by-product as another industries raw material inputs.

The beneficial use of CCP's from coal consumption use for energy is an important strategic plan for the sustainable use of coal, within an increasingly resource (finite) and emission (carbon) constrained society. While the principal product 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.

CCP's, being highly processed materials from the actions of milling and thermal processing, can if efficiently used, displace other traditional energy-intensive raw materials (product replacement). Resulting in conservation of finite mineral resources, the reduction or displacement of greenhouse emissions, through the recovery and use of these mineral resources.

Reduction in greenhouse gas terms is tangible and therefore within an increasingly carbon constrained society is a worthy motivation for developing innovative methods for recovery and use. Based on current national government policy, it would seem inevitable that a carbon pricing mechanism will re-emerge, and that it will include a suite of offset options that recognise greenhouse gas reductions achieved. This has and will bring further incentive to the productive recovery and future use of CCP's.

Australian producers and marketers of power station ash formed the ADAA with the objective of investigating and developing market opportunities for the use of these materials in various industry applications. The Association has and continues to deliver on this objective by striving to increase awareness by the generators, processors, regulators and end users awareness of the sustainable ecological benefits arising from the increased utilisation of these industry by-products for relevant industries, the community, and ultimately the environment.

Strategically, this has involved the execution of three primary objectives:

  • The initiation, analysis and dissemination of fundamental (pre-commercial) research and development initiatives in the recovery, processing and use of CCP's.
  • Advocating for the potential beneficial end uses and applications of CCP's to governments, regulators, and relevant industry organisations, both domestically and internationally.
  • Providing a regular forum for the exchange, consultation and analysis of relevant industry developments and information.

Local Fly Ash Beats Mined Frac Sand For Hydraulic Fracturing


The Research and Development team within LWP Technologies Limited has been testing Queensland-sourced FA at the pilot plant and the results from their work have been very positive and supportive of the path to commercialising cost effective FA based proppants for use in oil and gas hydraulic fracturing.

Another WO3nderful Use For Fly Ash


The chemically treated fly ash has gained the name OOPS and once it has absorbed oil from an oil-water mix, it floats on the surface of the water as a sticky substance that can be easily collected and transported and it can also be re-used in Coal-fire furnaces as fuel to generate heat and energy, once saturated.

Coal Combustion By-products Aren’t All Bad: The Beneficial Use Solution


Coal combustion residuals are often viewed as a troublesome burden—a waste product that coal-fired power plants struggle to deal with. Much has been written about disposal management strategies, and a lot of money is spent annually on landfills and monitoring. But in many cases, disposal is not the best option; beneficial use of the material could save money and reduce liability.

This article provides an interesting perspective on We Energies journey towards 100% benefical reuse of all coal combustion products from its faciliies, along with some novel developements and applications.
