Titan Group announced this week that it will build a processing and beneficiating unit for fly ash at Warrington in the UK. The move marks both a trend in fly ash projects in the UK recently and Titan’s own focus in the country.

Titan has struck a deal to use ponded fly ash at the former Fiddler’s Ferry power station in the North-West of England. It aims to process 300,000t/yr of wet fly ash from 2027 onwards with the option to double this capacity if desired. The processed fly ash will meet the BS EN 450 standard for subsequent use in cement or concrete. Crucially, Titan intends to use the technology of its subsidiary, ST Equipment & Technology (STET). This company has a proprietary dry electrostatic process that it uses for fly ash beneficiation. Titan acquired STET in 2002. It says its process is being used at 12 power stations in the US, Canada, the UK, Poland, and South Korea. The project at Fiddler’s Ferry will be the 20th fly ash project developed with STET technology.

Titan has not commented on the specifics of its arrangement with site-owner PEEL Group other than to describe it as a ‘long-term agreement.’ It currently operates a terminal in Hull, on the other side of the country, 160km from Warrington. As for Fiddler’s Ferry, the coal-fired power plant closed in 2020. Prior to this though RockTron Group built a 800,000t/yr unit at Fiddler’s Ferry to process both ‘fresh’ and stockpiled fly ash in the late 2000s. Unfortunately the company entered administration in 2013. Later, Power Minerals was reportedly selling fly ash from the plant at the time that its closure was announced in 2019. A report commissioned by consultants Arcadis for the local council reported that ash including pulverised fuel ash (PFA) was present in the lagoons at the site.

Other companies have also been looking at the fly ash market in the UK. Invicta, a joint venture between Türkiye-based Medcem and Brett Group opened a terminal at Sheerness in Kent in 2024 to import PFA and cement. In April 2025 a ship unloader supplied by Van Aalst was delivered to the port. Then in May 2025 it was announced that Mecem is planning to build a terminal in Liverpool to import cement and supplementary cementitious materials (SCM), such as fly ash and granulated blast furnace slag. The terminal will have a combined storage capacity of 45,000t in four silos in its initial phase and is scheduled for completion in mid-2026. Meanwhile, the Drax power station said in March 2025 that it had signed a 20-year joint venture agreement with Power Minerals to process legacy PFA. A unit at the now biomass power plant in Yorkshire is scheduled to start by the end of 2026 with an initial production capacity of 400,000t/yr.

The background to this interest in fly ash in the UK appears to be a local cement sector struggling with high energy costs and low capacity-utilisation rates. Reports in local media in late June 2025 cited preliminary estimates that cement output may have reached an ‘all-time low’ in 2024. High electricity prices were blamed for the situation by the Mineral Products Association (MPA) and it warned of mounting imports from the EU and North Africa. All of this was timed to coincide with a release of a new Industrial Strategy by the UK government.

Readers will be aware of the growing attractiveness of SCMs for cement and concrete production for both cutting costs and meeting sustainability goals. A report by McKinsey on SCMs for the cement sector in late 2024 forecast that SCMs and fillers in Europe could represent an emerging value pool that could reach €8 – 10bn in 2035 as the price of cement steadily rises. The SCMs being used are likely to change as sources of industrial SCMs such as slag and ash dwindle and others such as clays, pozzolans or limestone become more available. The UK may have closed its last coal-powered power plant in 2024 but ash from ponds can still be reclaimed or ash can be imported if the economics makes sense. Recent investments by Titan, Medcem and Power Minerals suggest that the price is indeed right. The interest of two major cement exporting companies amongst the three names above also indicates changing market dynamics. Expect more of these kinds of deals and investments in the UK, Europe and elsewhere in coming years.

US: Salt River Materials subsidiary Phoenix Cement Plant is working with ST Equipment & Technology (STET) on a fly ash separation system at a power plant in Utah. The cement producer previously secured a contract with a power plant in the state for the supply of fly ash to its Clarkdale cement plant in Yavapai county, Arizona. STET is supplying the separation equipment, engineering and commissioning services, and an exclusive technology operating license for Salt River Materials. Operations are schedule to start in mid-2021.

Pozzolan business senior vice president Dale Diulus said "Salt River Materials and STET have been working closely to develop a commercially effective beneficiation process improving the quality of the fly ash." He added "We look forward to many years of fly ash sales into the southwestern US markets."

US: Titan America has announced that it has recently formed ST Equipment & Technology LLC (STET), in order to further expand the development of its separation technology in fly ash and mineral applications worldwide. STET will be based in Needham, Massachussetts, US.

Mike Allen, who recently joined the Titan family of businesses, will serve as STET's President. His experience spans 30 years in international mining and minerals equipment and operations, most recently as Komatsu America Corp's Vice President of International Sales. He reports to current Titan America CEO, Aris Papadopoulos, who will become STET's Executive Chairman on 1 August 2014.
