Energy Australia has signed a memorandum of understanding (MoU) to supply fly ash from its coal-fired power plant in Yallourn to a proposed magnesium production plant in the Latrobe Valley.

At the World of Coal Ash 2017 Conference in the United States, CEO Craig Heidrich presented the following report to a plenary of +1,100. View the World Wide Coal Combustion Products Network PDF now.
The new-generation, high-efficiency coal plants produce half the carbon dioxide emissions of existing ones, making them comparable with gas and the Minerals Council says it is “simply common sense” that new coal technologies be considered as part of Australia’s efforts to meet its emissions reduction targets.
The Coal Combustion & Gasification Products Journal is a collaboration between the American Coal Ash Association and the University of Kentucky Center for Applied Energy Research, with the Ash Development Association of Australia's CEO, Craig Heidrich on the Editorial Board.
An important enabler in this journey for partners in the CRCLCL is to publish a Geopolymer Concrete Handbook as wider penetration of Geopolymer concrete within the construction industry affords a promising pathway to increase use of Low Embodied-Carbon construction materials.
Annual members and non-members were surveyed for CCPs generated, stored and sold during the reported period, which provides results for the calendar year; January to December 2015.
While lawmakers and environmental authorities are fixated on fly ash (FA) a potential hazard, many understand that the by-product is ‘A valuable resource.’ Duke University researchers explain that key components of technologies such as smart phones and electric car batteries include rare earth elements, which are found in abundance on the micro level in multiple FA ponds near Duke University in North Carolina.
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.
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.
The correlation between the amount of coal burnt and temperature is often strong and highly linear and this year North America’s winter rewrote the record books and was the hottest winter period ever documented. With temperatures averaging more than 5 degrees over the 20th century average. What does this mean for concrete manufactures and other Fly Ash users?
The Tennessee Valley Authority (TVA) has been responsible for the cleanup of the U.S Tennessee Kingston plant spill and eight (8) years on, the team are doing great. In the initail planning stage the team grouped engireers together to develop an innovative method of storing the fly ash.
Australia will be one step closer to achieving its environmenal sustrainability targets if we can effectively manage new industries using by-products as resources from old industries. It is in this space that an Australian fly ash industry may emerge, bringing with it innovative leaders and entrepreneurs to incorporate fly ash as an integral part of their business.
The burning of coal to make electricity creates two major by-products, fly ash and CO2 from smoke stacks. The ADAA and its members are currently doing everything possible to increase the utilisation of fly ash in the hopes of lessening the impact of burning coal on the environment. Although the utilisation of fly ash has been progressive, CO2 has been continuously viewed as a nuisance. Until now…
US based company, Southern Research is using $1 million in federal funding to develop and test a method to extract valuable rare earth elements (REEs) from coal fly ash, the minuscule waste particles captured by anti-pollution devices in coal-fired power plants. REEs are a series of chemical elements found in the Earth’s crust that are widely used because of their special properties. Increasing interest and research is being conducted into extract these elements from coal combustion products (Coal ash).
There has long been a considerable demand for coal ash products in the UK construction and engineering sectors. The UKQAA (UK Quality Ash Association) recently produced its Ash Availability Report, which showed that since the turn of the century, the construction industry has typically consumed half of what’s produced annually. This rose to 70% in 2014 as the economy showed real signs of growth and the sustainability agenda became more important to specifiers.
“Phosphorus can be extracted in viable quantities from fly ash. Sufficient phosphorus could be recovered from the country’s incinerators to meet 30 percent of the Swedish annual demand for mineral fertilisers, say the researchers.”
We want your feedback, thoughts and ideas about Coal Ash Matters and how we can improve it for you in the future to further promote the use of coal combustion products in Australia. Results from this short five minute survey will be published in a coming edition of Coal Ash Matters.
In 2015, the CRC for Low Carbon Living continues to forge ahead with its innovative research on geopolymer concrete as one of the most promising high volume applications of fly ash. Another project submitted to the CRC-LCL in 2014 aimed to gather field data from geopolymer real-life constructions to develop greater confidence in geopolymer use. Using the field and laboratory data, a comprehensive Handbook for geopolymer specification will be developed and published through Standards Australia.
The Cooperative Research Centre for Low Carbon Living approval for a 3 year project, RP1020: Reducing Barriers for Commercial Adaptation of Construction Materials with Low-Embodied-Carbon, will total $3.1 million and is well on track with progress to be reviewed in April 2015.
