Modern Farming: Fertilizing Plants with Synthetic Gypsum

Gypsum based fertilizer has top levels of calcium and sulfur, and is the world’s oldest and commonly used non-nitrogen-based fertilizers.

The nutrients that plants need in order to grow are the same nutrients that industry experts assert can be derived from the gypsum byproduct produced from coal-fired power stations. Gypsum has proven to have a wide variety of uses including being used to make drywall, cement filler, plaster of Paris, and even as a means of thickening tofu.

Gypsum can be found naturally all over the world in massive deposits, in places like the U.S., China and Iran. However, mining isn’t always practical, or economically viable. Densely populated countries like India, Vietnam, and China have been using the method of flue-gas desulfurization for years to remove sulfur dioxide and create what is commonly known as FGD gypsum. This gypsum is considered synthetic, but is almost identical to the material being mined throughout the world.  

Mined Gypsum and FGD Gypsum particles alike are consistent in their small size and ability to react in chemical and non-chemical reactions. Power stations that have not found a use for the byproducts created through the burning of coal such as fly ash, bottom ash, gypsum and more, are regrettably land-filled, costing companies money, time and energy to maintain these sites, and wasting land that could be put to better use.

FGD Gypsum has been determined safe for agricultural use through many studies, confirmed worldwide. The next step in this process is adaptation.  Join us at Coal Ash Asia 2019, August 22-24, in Youyu County, Shanxi Province, China, to discuss utilization and applications for FGD Gypsum and other highly useful byproducts from coal-fired power stations.

Coal Ash Asia 2018: A Recap

-Shuozhou City, Shanxi Province, China

A big thank you to everyone who participated in our Coal Ash Asia 2018 proceedings in Shuozhou City, China, this past September 12-15th. This year's topics focused on the high-value utilization of fly ash, FGD gypsum and coal gangue as well as highlight applications in building material products (cement, concrete, geopolymers etc).

A special thank you to our international delegation (click organisation to visit website):

We would like to extend our humble gratitude to our friends at the China Building Materials Academy’s Institute of Technical Information for the Building Materials Industry, in Beijing. This year’s extension and construction of our annual products and services exhibition was our largest in Coal Ash Asia history, with over 50 exhibitors, and a welcome ceremony which included an orchestra playing on instruments made primarily from fly ash!  

New to this year’s proceedings was our Technology Symposium track geared towards new technologies in fly ash, which included discussion on fly ash based aggregates, fillers, and ceramic tiles. Contributors to this track included: Prof. Chang Jiqing from Guangdong Penghu Industrial Co., Ltd., Zhang Jingjie from Shanxi Hujin Coal Electricity New Material Co., Ltd., Ma Liantao from Hengyuan Waste Utilization, and Peter Ma from Shandong Wei Tong Technology Co., Ltd.

Another new feature was our meeting dedicated to new FGD gypsum technologies. Content included alpha high strength gypsum and calcination methods. Contributors included: Prof. Duan Pengxuan from Guilin University of Technology, Prof. Xiang Lan from Tsinghua University, and Li Yushan from Shandong Pingyi Kaiyuan New Building Material Co., Ltd.

This year also welcomes esteemed contributor, Mr. Bill Martin, who led engaged attendees in his workshop, “Fly Ash Use in Road and Embankment Construction”. Here, Mr. Martin led the discussion for industry experts, who explained real-world projects of American and Australian fly-ash in road projects. Also discussed were new technology and applications in road engineering. Attendees were able to openly discuss and compare methods and approaches to road construction, and receive technical explanations as to the process of applying road and embankment technology from start to finish.

We are excited to announce upcoming events and association/research developments in the new year. Please sign up for our newsletter to stay in touch!

Cenosphere Production to Increase Significantly by 2020


"Cenospheres Market - Global Trends & Forecasts to 2020”, a new report available at www.researchandmarkets.com since January 2016 delivers an inclusive analysis regarding global cenosphere trends.

Between 2015 and 2020, researchers expect the compound annual growth rate of cenospheres to grow by over 12% per year. At the end of this five year term, the market for cenospheres is said to be worth $572 million, globally. The demand for cenospheres in places like the U.S, and China are said to be the cause of this projection. Other countries whose demand for the product increases everyday are France, Germany, Japan and India. North America is the largest consumer of cenosheres, followed closely by Europe.

Cenopsheres are predominantly used by the oil and gas industries. Following this lead is the refractory industry, which is experiencing a heightened demand for furnace and construction applications. 

Expansion and the acquiring of resources appear to be the conclusion of the presented materials. China and India have developed within the market and have created high expectations within the Asian market as a whole. The Asia-Pacific region appears to be the most strategic as this region has undertaken a variety of initiatives. The increase in domestic participants and steady growth in local manufacturing are just a couple factors contributing to the expanding global cenosphere market.

Asian Coal Ash Association participation in World of Coal Ash

Nashville, Tennessee 

World of Coal Ash, the coal combustion product industry's longest-running international event, drew a record turnout this year with more than 800 attendees participating in short-courses, presentations and the largest ever exhibition held at the Nashville Convention Center in Nashville, Tennessee. The Asian Coal Ash Association participated as an exhibitor at WOCA, promoting the upcoming Coal Ash Asia 2015 event. AsianCAA also assisted in the organisation of a delegation of industry leaders from China, in collaboration with ITIBMI and Coal Ash Solutions Ltd. AsianCAA chairman David Harris also participated as a keynote speaker and panelist in the plenary session.

The record turnout at WOCA 2015 was accompanied by renewed optimism amongst WOCA participants, widely attributed to the US Environmental Protection Agency's December 2014 signing of the final ruling on "Disposal of Coal Combustion Residuals". This final rule supports the responsible recycling of CCRs by distinguishing safe, beneficial use from disposal. Following 6 years of extensive study on the effects of coal ash on the environment and public health, the final ruling delivers a degree of regulatory certainty around disposal, transportation and utilisation of coal combustion products. This regulatory clarity provides guidance and mitigates regulatory risk for industry stakeholders looking to make responsible investments in ash management and utilisation.
