Belarusian cement industry expands use of RDF

25 September 2025

Belarus: The country’s cement sector is intensifying efforts to use refuse-derived fuel (RDF) in cement production, according to the state information agency Belarus Telegraph Agency.

Belarusian Cement Company introduced an RDF processing line in 2021 at OAO Krasnoselskstroymaterialy in Grodno Oblast, enabling full incineration of RDF supplied by local waste-processing plants. Contracts are reportedly already in place with RDF suppliers for 25,000t of the fuel to be delivered by the end of 2025.

In September 2025, industrial trials of RDF made by Minsk-based Ekores will begin. If successful, shipments from the company could double from 15,000t to 30,000t, raising total RDF use to 40,000t in the final quarter of 2025.

Plans are also underway to expand RDF infrastructure in 2026, with a regional municipal waste management and RDF production complex under construction near Volkovysk.

South Korea pilots recycling of textile waste into alternative fuel

16 September 2025

South Korea: The Ministry of Environment has announced a pilot project to recycle waste fabric scraps from sewing factories into alternative fuel for the cement industry. The agreement has been signed with: textile companies Pang Rim, Sewang, Sinhan Spinning & Textile; cement companies Ssangyong C&E and Asia Cement; and the Korea Recycling Service Agency (KORA). It expands on an earlier initiative launched in 2024 with four Seoul districts.

Under the project, fabric scraps that were previously incinerated or landfilled will be separated, sorted and processed into intermediate fuel, which cement plants will use in the production process. The Ministry said that KORA will support raw material supply and recycling logistics, while cement firms will adopt the fabric-derived fuel to reduce waste and fossil fuel use.

Kim Go-eung, Director General of the Resources Circulation Bureau, said “The separation, sorting and recycling of waste are essential elements for producing high-quality recycled raw materials. To establish a circular system, we will continue to identify and expand various measures so that the supply of excellent recycled raw materials and the securing of demand sources can be balanced.”

Tiruchi sends plastic waste to cement plants as alternative fuel

16 September 2025

India: Tiruchi Corporation has intensified efforts to manage non-recyclable plastics by diverting them to cement plants for use as alternative fuel. The city generates 400 - 450t/day of waste, of which about 75% is segregated at source. Non-recyclable plastics are collected through door-to-door systems and sent to Dalmia Cements’ and UltraTech Cement’s plants, where they are used as refuse-derived fuel (RDF) in the kilns. Since July 2024, 2384t of plastics have been diverted to cement plants.

An upcoming automated material recovery facility at Ariyamangalam, with a capacity of 250t/day, is expected to further improve segregation, ensuring recyclable, non-recyclable, inert and RDF streams are directed to cement plants for reuse.

Moctezuma opens alternative fuels storage system at Tepetzingo plant

11 August 2025

Mexico: Moctezuma inaugurated a US$12m alternative fuels storage system at its Tepetzingo cement plant in Morelos, after two years of engineering, planning and execution. The facility will process over 150,000t/yr of waste, including end-of-life tyres, municipal solid waste and non-recyclable materials, which will replace fossil fuels in cement production, with a goal of 30% substitution by 2030. The company said that the benefits of the project include saving thousands of tonnes of waste from landfill and mitigating methane emissions.

The producer, the Morelos government and the Ministry of Sustainable Development are also developing a circular economy centre in Jiutepec with an additional investment of US$1.6m. The facility will collect, shred and convert up to 3000t/month of tyres into alternative fuels.

Japanese cement producers used 21.9Mt of waste in 2024 financial year

21 July 2025

Japan: Cement producers used 21.9Mt of post-consumer materials and by-products in the 2024 financial year, down by 3% year-on-year, marking the third consecutive annual decline, according to the Japan Cement Association.

Coal ash and blast furnace slag, which together make up over 50% of the total, both declined, although post-consumer plastics increased for a fourth consecutive year.

Cement production, including clinker for export, also fell by 3% to 45.7Mt. The amount of byproducts used per tonne of cement dropped from 480kg in 2023 to 478kg, but remained above 400kg for the 21st year in a row.

Holcim Colombia upgrades Nobsa cement plant’s co-processing platform

10 July 2025

Colombia: Holcim Colombia has invested US$2m to modernise its co-processing platform at its Nobsa cement plant in Boyacá. The upgraded facility will process 100,000t/yr of waste into alternative fuels for the cement plant, raising thermal substitution to 40% in the short term, with a target of 70% by 2030.

CEO of Holcim Colombia Martín Costanian said “This project realises our dream of optimising the crushing circuit and scaling our capacity to replace fossil fuels with more sustainable and truly circular solutions.”

The system renovation includes the addition of a shredder with a nominal capacity of 10t/hr, as well as new transfer systems and a modern dosing system capable of feeding up to 20t/hr of alternative fuels to the kiln. The waste used will consist of paper, cardboard, plastics and biomass.

Manager of Geocycle José Méndez said “This project represents true circularity and a solution for the thousands of pieces of waste that end up in landfills each year.”

Titan Group to build fly ash beneficiation facility

08 July 2025

UK: Titan Group will build and operate a processing and beneficiating facility for ponded fly ash at the former Fiddler’s Ferry power station in Warrington, following a long-term agreement with site owner Peel NRE. The plant will process 300,000t/yr of wet fly ash from 2027, with scope to double the capacity at a later date. Titan will use the material in low-carbon cement, while Peel NRE will receive help to advance restoration of the site. The ash will reportedly meet BS EN 450 quality standards.

Peel NRE director Kieran Tames said “We are very pleased to have reached this agreement with Titan, which follows years of hard work fully evaluating the potential to transform the waste ash material from the power station directly into a low-carbon construction product. This agreement has the potential to accelerate the recovery of waste ash from the lagoons, enabling their restoration and enhancement as envisaged by the development framework that was approved by the local authority last year. Through our partnership, existing customers will continue to source ash from the site, ensuring continuity of supply for their applications.”

Fletcher Building to use plastic waste as alternative fuel for cement production

25 June 2025

New Zealand: Fletcher Building will begin using hard-to-recycle plastics and wood as alternative fuels in its cement production process during 2025, as part of its ‘front-end firing project’, according to The Post newspaper. The company aims to be 100% coal-free by 2030. It said wood pellets and shredded tyres currently substitute for 50% of coal. The new additions will raise this to 70–80%. Fletcher Building began burning wood pellets in 2003, construction waste in 2010 and tyres in 2023. Fletcher Building said it plays a “significant role in waste diversion for New Zealand."
