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.”

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.

Ireland/UK: Mannok has completed Phase 1 of a two-phase upgrade to its pyroprocessing system with the installation of a new satellite burner in collaboration with FLSmidth. The €2.5m project enables the use of solid recovered fuel (SRF) as a replacement for coal, achieving up to 30% substitution and reducing CO₂ emissions by 23,000t/yr.

Phase 2 will involve upgrading the main burner to a Jetflex system, targeting 65–70% coal substitution across the kiln. Mannok produces about 1.4Mt/yr of cement for customers across the UK and Ireland.

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.
