Zementwerk Hatschek's Gmunden cement plant eliminates 3800t/yr of local CO2 emissions with WHR heating
24 January 2023Austria: Zementwerk Hatschek's Gmunden cement plant eliminated 3800t of CO2 emissions from its local area during 2022 through its contribution to municipal heating. Zementwerk Hatschek, a subsidiary of Rohrdorfer, heats local households using recovered heat from the Gmunden cement plant's waste heat recover (WHR) system.
A delegation of cement plant representatives and local officials from Baden-Württemberg, Germany, visited the plant to learn about its WHR and heat supply systems on 20 January 2022.
Plant manager Peter Fürhapter said "Municipal heating based on our waste heat contributes to CO2 reduction in Upper Austria, helping us to achieve our CO2 reduction goals under the Paris Climate Agreement." He added "We are pleased that with this forward-looking project we are a model for similar projects in Europe."
Thai cement plant installs ThyssenKrupp Polysius' Prepol SC alternative fuels system
19 January 2023Thailand: ThyssenKrupp Polysius says that it has successfully supplied and installed a Prepol SC alternative fuels (AF) system at a 12Mt/yr cement plant in Thailand. The system will supply the plant's four lines with 4000t/day of AF.
ThyssenKrupp Polysius' Asia Pacific CEO Lukas Schoeneck said "Asia Pacific, with its tremendous municipal solid waste (MSW) problem, is ideal when it comes to replacing coal with AF. The Prepol SC technology significantly reduces the need to treat MSW before using the inherent calorific value. Additionally, it helps to further reduce the ambitious CO2 limit targets in the region."

FLSmidth introduces new strategies for cement and mining sectors
18 January 2023Denmark: Equipment manufacturer FLSmidth has launched new corporate strategies for its cement and mining sectors. The so-called ‘pure play’ plans are intended to further focus on technology, products and services and sustainability. The group says it is also simplifying its operating model to reduce risks, improve efficiencies, ensure stronger execution and improve profitability and quality of earnings. The announcement was made at the same time as the group’s latest investor event.
Mikko Keto, the chief executive officer at FLSmidth, said “We must prioritise our efforts on our core business, reduce risk and execute with excellence. We have already started to fundamentally transform our business to ensure stronger strategy execution and to achieve our long-term ambitions to the benefit of our stakeholders.”
In the cement sector the group’s ‘Green 26’ plan aims to make the company the preferred service supplier for the industry. It added that it has a “clear commitment to drive the green transition in the cement industry.” It has set a target of reaching an 8% earnings before interest, taxation, depreciation and amortisation (EBITDA) margin by 2026. For the mining sector the target is a 13 - 15% margin.
In provisional financial results for 2022, FLSmidth revealed that it had an EBITDA margin of 3.3% for cement and 7.6% for mining. Group revenue rose by 24% year-on-year to Euro2.93bn in 2022 from Euro2.37bn in the 2021. Revenue from the cement and mining sectors grew by 7% to Euro847m and 29% to Euro2.03bn respectively. The group said that the short-term outlook for the cement industry remained impacted by overcapacity and that a potential recession is expected to impact market demand negatively over the coming period. Its mining sector revenue was inflated by the acquisition of ThyssenKrupp Mining in 2022.
US: Sublime Systems says it has secured US$40m in funding from its latest investment round. Venture capital company Lowercarbon Capital, The Engine, Energy Impact Partners and others took part in the Series A funding round. Siam Cement Group has also been announced as a strategic investor. The company will use the new capital to increase production at its pilot plant, build its team, conduct product testing and promote offtake commitments from new customers and partners.
Sublime Systems is commercialising an electrolysis cement production process that will manufacture cement at ambient temperature from a variety of abundant calcium sources. It says it is the first company to produce cement through this process.
Leah Ellis, co-founder and chief executive officer of Sublime said, "We have successfully demonstrated the viability and scalability of our approach and we are able to produce cement with the same or better strength, slump and durability than today's Portland cement. The support of our talented team and capital from our investors will enable us to operate our pilot facility, secure advance offtake agreements and work toward producing our low-carbon cement at scale."
The company was spun-out of the Massachusetts Institute of Technology (MIT) in 2020. It was co-founded by Yet-Ming Chiang, an MIT professor and co-founder of several climate-tech companies, including A123 Systems, 24M Technologies and Form Energy, and Leah Ellis, an Activate Fellow and one of MIT Technology Review's 35 Innovators under 35. To date, the company has concentrated its efforts on developing its first drop-in, low-carbon cement product, validating its manufacturing process at the pilot scale, validating buyer demand and building up its team.
