Ireland/UK: A six-month feasibility study conducted by Mannok at its Derrylin plant, in conjunction with Catagen, has found a number of ways that the cement producer can reduce its CO2 emissions. Using Catagen’s HGEN renewable hydrogen generator with waste heat recovery could potentially decrease the cement plant’s annual CO2 emissions by 7%. In addition the study found that using biohydrogen generation from waste biomass could generate larger volumes of hydrogen with less renewable energy required, compared to electrolytic hydrogen generation. Using Catagen’s BIOHGEN process in this way could minimise carbon intensity by a further 18%. A combined group of engineers from Mannok and Catagen worked on the project.
Kevin Lunney, operations director at Mannok, said “We are very excited to be working with the Catagen team, who have demonstrated a deep level of technical ability and competency during the feasibility work. I have no doubt that Mannok will derive significant value from the work already completed, with many new opportunities for collaboration now presenting that we would not have considered before. Achieving Net Zero is now the primary goal for our business and I expect Catagen will play a significant role in our achieving that goal, which we expect will have major benefits for the sector overall.”
In early April 2023 Mannok revealed that it had secured funding from the UK Government Green Energy Scheme to support its energy transformation programme. The first phase of the initiative, which the funding will support, is the generation of onsite green hydrogen to replace the use of diesel in over 70% of the company’s 150 heavy-goods truck fleet.
Belfast-based Catagen started as a testing company providing emissions data to the automotive sector. It has started working in other industrial sectors - such as cement, glass and steel in Europe and the US – as part of its ClimaHtech product range.
Bestway Cement inaugurates Mianwali cement plant

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."
Savannah Cement to establish 2.92Mt/yr clinker plant in Kitui
12 December 2022Kenya: Savannah Cement has hired China-based Sinoma International Engineering for construction of its upcoming 2.92Mt/yr Kitui clinker plant in Eastern Province. The plant will additionally have a 900,000t/yr grinding unit, a 35MW fossil fuel-fired captive power plant and a 13MW waste heat recovery (WHR) system. Savannah Cement chair Benson Ndeta said that the plant will convert to 100% solar and WHR-powered production by the end of 2029.
Sinoma International Engineering plans to commence the project immediately, and to complete it in late 2024.
Bestway Cement is a Carbon Neutralisation Pioneer
28 November 2022Pakistan/UAE: China-based renewables supplier LONGi Green Energy Technology has awarded Bestway Cement its Carbon Neutralisation Pioneer award at a ceremony in Dubai, UAE. The award acknowledges progress in industrial sustainability during the past year. Bestway Cement is the first Pakistani recipient of the prize.
Bestway Cement operates 62MW-worth of solar power capacity at installations at its Chakwal, Farooqia, Hattar and Kallar Kahar cement plants. Managing director Irfan Sheikh said that this setup enables it to minimise CO2 emissions and the company's reliance on the national grid. Bestway Cement was also the first Pakistani cement producer to install waste heat recovery (WHR) plants across all of its integrated cement plants.
Ramco Cements to build second line at Haridaspur grinding plant
11 November 2022India: Ramco Cements has approved plants to build a second production line at its Haridaspur grinding plant in Jajpur District, Odisha with a capacity of 0.9Mt/yr. Around US$16m has been earmarked for the project. Once commissioned the plant’s total capacity will be 1.8Mt/yr.
The cement producer’s revenue grew by 31% year-on-year to US$442m in the first half of its financial year to 30 September 2022. However, its earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 35% to US$61.9m. It blamed the loss in earnings on falling cement prices and mounting fuel costs. The company currently has cement and clinker production capacities of 21Mt/yr and 14Mt/yr respectively. It also reported that a 6MW waste heat recovery unit at its Kurnool plant in Andhra Pradesh will be commissioned in November 2022. An additional 6MW at the same plant is scheduled to start operation in March 2023.

Makin Teguh and Borneo Oil mark firing up of kiln at ILPP cement plant
20 September 2022Malaysia: Makin Teguh and Borneo Oil have held a ceremony to mark the firing up of the kiln at the 0.23Mt/yr ILPP cement plant being built in Sabah. The new plant is next to a limestone quarry owned by Borneo Oil and it is set to further benefit from the oil company’s other limestone assets via long term supply contracts, according to the Borneo Post newspaper. Borneo Oil increased its stake in Makin Teguh to 38% in May 2022.
A China-based supplier has built the new plant. It includes a waste heat recovery (WHR) unit and it reportedly the first integrated cement plant in Malaysia to use alternative fuels such as heavy fuel oil derived from refined recovered oils, palm kernel shells and bio char.
