US: Eco Material Technologies has won a contract with Georgia Power to mine 600,000t/yr from the energy company’s Plant Bowen ash dump in Cartersville, Georgia. Eco Material Technologies will use the ash to produce its 99% reduced-CO2 building materials, including an alternative cement with 20% greater compressive strength than ordinary Portland cement (OPC) after 28 days, according to the company.
Grant Quasha, CEO of Eco Material Technologies, said "As the largest partnership of its kind in the US, this project will not only use material from landfills and ash ponds, but also keep millions of tonnes of CO2 from going into the atmosphere."

Vicem Hoàng Mai Cement targets US$79.2m in sales in 2022
07 April 2022Vietnam: Vicem Hoàng Mai Cement has announced a full-year sales target of US$79.2m for 2022, down by 1.5% year-on-year from 2021 levels. Its target net profit for the year is US$656,000, more than five times its 2020 figure. The company forecasts cement production of 1.73Mt, up by 11% from 1.56Mt, and clinker production of 1.4Mt, down by 4.1% from 1.46Mt, for the year. It plans to replace 30 – 40% of the natural gypsum currently used in cement production with synthetic gypsum. It will also increase the proportion of ash and slag in its raw materials mix.
The Chúng Khoán newspaper has reported that Vicem Hoàng Mai Cement said that it is experiencing increased costs due to high raw materials and fossil fuel prices. A coal shortage has also disrupted production.
Conch North Sulawesi Cement uses 50t/day of fly ash and bottom ash in its cement production
23 March 2022Indonesia: Conch North Sulawesi Cement is receiving 50t/day of fly and bottom ash from the Amurang coal-fired power plant in North Sulawesi. Koran Metro News has reported that the Semen Conch subsidiary uses the ash as a supplementary cementitious material (SCM) in its cement production. The Amurang power plant currently holds 80,000t of the byproduct in stockpiles.
Eco Material Technologies acquires Green Cement
15 February 2022US: Eco Material Technologies has successfully completed its acquisition of near-zero carbon cement alternatives producer Green Cement. Eco Material Technologies previously agreed to acquire Boral’s US fly ash business in December 2021, a transaction which it expects to conclude in 2022.
Innovative Ash Solutions to establish 20,000t/yr ash processing plant in South Lanarkshire
02 December 2021UK: Innovative Ash Solutions has received a Euro588m Scottish government grant to establish a 20,000t/yr ash processing plant in South Lanarkshire. The Herald newpaper has reported that the plant will process boiler ash, cyclone ash and incineration fly ash for use in local cement production. When commissioned in 2022, the plant will eliminate 6104t/yr of CO2 emissions, according to the operator. The government granted the funding under its Zero Waste Scotland circular economic investment scheme.
The company said “Using this new patented process, which diverts waste materials from landfill and avoids the use of virgin sand, creates a product which is cheaper and will reduce the environmental impact of cement production compared to the use of imported pulverised fuel ash.”
Innovative Ash Solutions is a joint venture of waste management company Levenseat and consultancy Organic Innovative Solutions.
Charah Solutions wins ash and boiler slag handling contract with Associated Electric Cooperative
04 November 2021US: Charah Solutions has signed a contract with Associated Electric Cooperative (AECI) to receive bottom ash, fly ash and boiler slag from its Thomas Hill Energy Center coal-fired power plant in Missouri until 2026. Charah Solutions will recycle the by-products to produce supplementary cementitious products and redistribute these through its MultiSource materials network. The network consists of 40 locations across the US.
President and CEO Scott Sewell said "We are delighted to partner with AECI to manage their ash marketing needs at Thomas Hill while supplying our concrete producers with the high-quality material they need."
Germany: Scientists at the University of Kassel in Hessen have launched a study into the use of ash from waste incinerators in precast concrete production. The Hessische Allgemeine newspaper has reported that a waste-to-energy plant in Kassel will provide the ash for concrete production in partnership with local companies Kimm Baustoffe and Gebäudeke Baustoff-Recycling. The study aims to produce pre-cast concrete elements containing at least 30% ash, beginning with paving slabs and noise barriers.
Project leader David Laner said that ash has the potential to help lower concrete’s carbon footprint. He said “So far, it has been put to lesser-value uses; we make a product out of it - upcycling instead of downcycling.”
Murdoch University team develops Colliecrete fly ash-based concrete
20 September 2021Australia: Researchers from Murdoch University in Western Australia have developed a cement-free concrete called Colliecrete. ABC News has reported that the concrete comprises of 80 – 90% fly ash. Other ingredients are bauxite residue and recycled aggregates. Developer Ramon Skane said that customers can make Colliecrete ‘anywhere, at room temperature.’
US: Titan America, part of Greece-based Titan Group, has launched ProAsh and EcoTherm. Both products are made from ash reclaimed from landfill and can be used in both cement and concrete production. Titan America subsidiary Separation Technologies produces the materials at its Brunner Island reclaimed ash drying and electrostatic separation plant in Pennsylvania.
President and chief executive officer Bill Zarkalis said, “This breakthrough achievement represents Titan America’s commitment to the reduction of CO2 through innovation as we plan to deploy this technology across the construction material sector.” He added “By harnessing the power of this technology, Separation Technologies is utilising a revolutionary beneficiation process that is capable of converting reclaimed ash from ash basins in an efficient manner. The result is a high-grade, low carbon construction product.”
