Australia: Adbri is targeting 40% refuse derived fuel (RDF) substitution in cement production at its Birkenhead, South Australia, cement plant in 2022. By 2024, it aims to further increase RDF use to 50%. The plant used 35% RDF in its production in 2021.

Adbri says that it is Australia's only cement producer not to use coal, relying instead on a combination of RDF and gas.

Canada: St Mary’s Cement plans to apply for a licence to substitute alternative fuel (AF) for a part of its coal, gas and petcoke fuel mix. The plant previously held a two-week AF substitution trial in May 2011. CBC News has reported that the subsidiary of Votorantim Cimentos will present its plan at an evening meeting for the general public on 18 November 2021. The company says that it plans to implement similar AF arrangements to those at its Bowmanville plant, where it uses 90,000t/yr of biomass, wood from construction and demolition and non-recyclable paper and plastics.

Environmental manager Ruben Plaza said "Lower CO₂ emissions is the first consideration and, equally as important, the material has to be approved and available in sufficient quantities with a reliable and sustainable long-term supply."

Philippines: Holcim Philippines and its waste management subsidiary Geocycle have together inaugurated a waste processing plant and alternative fuels (AF) storage facility at the former’s Bulacan cement plant. The facilities consist of municipal solid waste (MSW) shredding equipment and a 5400m² warehouse. The installation is part of a US$2.41m investment by Holcim Philippines in the Bulacan plant, aimed at reducing its CO₂ footprint and increasing the circularity of its operations. The plant will produce its AF from MSW from the Boac municipality.

President and CEO Horia Adrian said “This initiative is part of our bigger commitment to make our operations more sustainable. These facilities will further reduce our carbon footprint and energy costs, while providing our partners with a safe and environmentally sound waste management option though our co-processing technology. We are excited to continue these projects to help us get closer to our long-term ambition of using 70% AF in cement production, instead of coal."

Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.

UK: Helvellyn Group, a manufacturer of high energy, low impact solid fuels, has announced the official launch of its cement industry direct coal replacement product in Europe.

Helvellyn has chosen the Global Cemfuels Conference (Paphos, Cyprus 19 - 20 February 2020) as the location for the launch and will be sponsoring the event as well as attending in person.

Helvellyn solid fuels are designed to meet the needs of hard to adapt large industrial plants that are seeking to reduce, or even eliminate, their reliance on coal. The fuels are manufactured to replicate the physical and combustion properties of coal, while reducing the greenhouse gas emissions associated with mining, transporting and burning fossil fuels.

This latest renewable coal replacement fuel has been developed to address the specific needs of cement producers, many of whom have already introduced alternative fuels but are now struggling to increase the ratio due to physical, chemical and technical constraints.

Helvellyn’s product allows operators to maintain their existing alternative fuel mix while, in most instances, adding Helvellyn fuel as a direct drop-in replacement for coal from the point of delivery through pre-combustion processing and in combustion.

The Helvellyn fuel for cement production is based on four core principals, high energy, low moisture, low chlorine and ease of handling. While exact fuel specification and presentation can be fine-tuned to meet the specific needs of a given plant, fuel is typically presented as 50mm hard, hydrophobic lumps with the following properties: energy >25kJ/kg (10,750btu/lb, 5.97kcal/kg); ash content <6%; moisture <2%; chlorine <0.07%; carbon >60%; sulphur <0.2%; nitrogen <0.4%.

Frank Harris, CEO of Helvellyn Group, said, “We are delighted to be launching this important product at the Global Cemfuels Conference 2020. The cement industry has shown innovation and leadership in utilising alternative fuels and we believe we can help them to meet the challenges of the next decade as they further reduce the environmental impact of their product. We are excited to meet with the industry and let it see our fuel for the very first time - it is like nothing they will have seen before.”

India: Birla Corporation has been granted use of two coal mines in Madhya Pradesh. Accord has reported that the mines will provide ‘cost optimisation and fuel security’ to Birla Corporations and its subsidiaries in their central Indian operations.

Ethiopia: The Ministry of Trade and Industry, and the Chemicals and Construction Inputs Industry Development Institute are working with cement producers to replace imported coal with biomas in a bid to lower carbon CO2 and reduce reliance on foreign currency. The institute has conducted a feasibility study, with the support of the Global Climate Fund and the European Union, studying using a weed, Prophecies Newfora, as potential biomass, according to the Reporter newspaper. Plants run by Dangote Cement and Habesha Cement factories took part in the study. The government is also encouraging cement producers to use locally mined coal until the biomass project becomes fully operational.

Uzbekistan: The government is preparing to increase the use of alternative fuels in the cement and lime industry. A draft decree intends shift local industry to meet global trends in energy consumption and away from natural has consumption, according to the Trend News Agency. The government intends to encourage the use of coal, wood briquettes and pallets, biogas and other fuels.

The Ministry of Energy, together with the Academy of Sciences and research institutes, is planning to develop energy efficiency levels for industrial gas boilers. Local gas suppliers Uzneftegazinspektsiya, Uzenergoinspektsiya and Uztransgaz will then stop supplying natural gas to non-compliant industrial users from the beginning of 2020.

UK: N+P says that Subcoal production will start at its Teeside plant in July 2019. Following nearly a year of de-commissioning and site preparation works. The project has achieved financial close and construction work has commenced following nearly a year of de-commissioning and site preparation works. The plant will consume 0.25Mt/yr of commercial and industrial waste feedstock and will produce 0.19Mt/yr of N+P’s Subcoal product. The engineering, procurement and construction (EPC) contractor is Fairport Engineering.

The Teeside plant will supply Subcoal pellets to different outlets including Simec Atlantis Energy (SAE) for use in its Uskmouth 220MW coal-fired power station, which is being converted from coal to waste-derived fuel. N+P and SAE have agreed a fuel-supply agreement to supply nearly 1Mt/yr to the power station once it has been converted to using Subcoal in place of coal in 2021. To meet demand for the contract, N+P plans to build a further three Subcoal plants.

Egypt: Khaled Fahmy, the Minister of Environment, has opened a new production line at Arabian Cement Company’s Ain Sokhna plant in Suez. The line uses FLSmidth’s Hotdisc combustion device to allow it to use high levels of alternative fuels, according to the Watani newspaper. The opening was attended by Muhammad Shehab Abdel-Wahab, chief executive of the Egyptian Environmental Affairs Agency, Nahed Youssef, head of waste management organisation, as well as a number of representatives of the financiers, and director of the European Investment Bank.

In 2015 Arabian Cement Company commissioned another Hotdisc installation. At the time is said it had a designed fuel mix of 70% coal and 30% alternative fuels, using a mixture of agricultural wastes, municipal sludge, and refuse-derived fuel (RDF).
