Mexico: Cemex has launched its global waste management subsidiary Regenera. Regenera will be involved in the reception, management, recycling and coprocessing three major waste streams: municipal and industrial waste, construction, demolition and excavation waste (CDEW) and industrial by-products. It will tie in with Cemex’s own cement sustainability initiatives, for instance in its supply of waste recovered from the River Nile to Cemex Egypt’s Assiut cement plant for co-processing as alternative fuel (AF).

Ireland: A court has ruled that the Irish government need not pay legal costs for Environmental Trust Ireland president Michelle Hayes' challenge against the Environmental Protection Agency (EPA) in mid-2022. Hayes unsuccessfully sued the EPA for issuing Irish Cement with a licence to use alternative fuel (AF) at its Limerick cement plant in May 2021. The AF will comprise up to 90,000t/yr of waste tyres, biomass and/or mining by-products.

At the costs hearing, the court noted that Hayes had already caused the EPA to incur 'very significant' legal costs. The court said that Hayes 'sought to have the taxpayer pay even more.' It added that, as a solicitor at Hayes Solicitors Limerick, which represented her in her unsuccessful challenge, Hayes stood to effectively benefit from any recuperated costs. The court concluded "It would mean that legal practitioners like herself are paid by the taxpayer for bringing environmental litigation which is unmeritorious."

Thailand: 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."

India: Adani Cement has announced the launch of a dedicated waste processing subsidiary called Geoclean. Geoclean will process waste for recycling and use as alternative fuel (AF) in its cement production and alternative raw materials in its production of other building materials. Geoclean inherits the projects and all 14 waste management plants of its predecessor company Geocycle India. The Orissa Diary newspaper has reported that Geoclean aims to help Adani Cement to co-process 3.7Mt of AF over the five-year period up to the end of 2027. This would raise its subsidiaries ACC and Ambuja Cements’ AF substitution rate to 30%, from 6% in 2021.

Adani Cement CEO Ajay Kapur said "We are committed to building a sustainable future by adopting clean and green technologies in our overall business. We have always believed in environmental conservation, and are committed to making the optimum contribution towards co-processing waste responsibly for a sustainable future. Adani Cement will continue its endeavours to promote sustainability and build a cleaner and greener planet."

Mexico: Cemex Mexico plans to install hydrogen injection systems at four cement plants across Mexico. The producer will use the technology to increase alternative fuel (AF) substitution at the plants by 8 - 10%. A 40% reduction in Scope 3 purchased fuel emissions forms part of Cemex's 2020 -2030 CO₂ emissions reduction strategy. Through the decarbonisation and circular economy pillars of its Future in Action plan, the group aims to become carbon neutral by 2050.

Cemex Mexico president Ricardo Naya said "Hydrogen is a key technology to accelerate the implementation of our climate action roadmap."

The El Financiero newspaper has reported that Cemex set a new group record AF substitution rate of 34% in September 2022. It uses hydrogen at all of its European cement plants and at one plant in the Dominican Republic.

Dominican Republic: Cemex Dominicana has announced the signing of a new sustainability agreement with food producer Nestlé Dominicana. Under the agreement, Cemex Dominicana will co-process Nestlé Dominicana's non-recyclable high-calorific solid industrial waste as alternative fuel (AF) in its cement plant.

Cemex's Dominican Republic, Puerto Rico and Haiti regional director José Antonio Cabrera said "This agreement with Nestlé allows us to continue promoting our Future in Action strategy by operating our cement plant with AF." He concluded "We are committed to becoming a net-zero CO₂ company."

UAE: The Ministry of Climate Change and Environment (MOCCAE) and Emirates RDF have signed four memoranda of understanding (MOU) with Fujairah Cement Industries, JSW Cement, Lafarge Emirates and Star Cement to use alternative fuels produced by the Emirates RDF in the Umm Al Quwain Emirate in their manufacturing operations.

Emirates RDF’s plant treats and transforms municipal solid waste (MSW) from Umm Al Quwain and the emirate of Ajman into refuse derived fuel (RDF). The ministry said in a statement that MOUs are part of its support for integrated waste management projects that treat waste and transform it into economic resources in line with the Ministerial Decree No. 98 of 2019 on using RDF in cement factories. Cement plants in the UAE will be encouraged to meet 10% percent of their total thermal energy needs using RDF.

Mariam bint Mohammed Almheiri, Minister of Climate Change and Environment, said, “The participation of the private sector is a main pillar of the UAE’s green economy transition and the adoption of circular economy methods, the foremost of which is integrated waste management. The signing of the agreements with a group of leading cement factories in the country to partially use alternative fuel in their operations is a high-impact step within our efforts to implement integrated waste management and reduce harmful emissions.”

South Korea: SK Ecoplant is at the centre of an initiative in partnership with the city administration of Seoul to co-process 110,000t/yr of sewage sludge from the city as alternative fuel (AF) for cement production. AJU News has reported that the waste management company expects the sludge to fuel 150,000t/yr of local cement production under the initiative.

Seoul generates 200,000t/yr of sewage sludge.

Spain: Cementos Portland Valderrivas has partnered with the University of Seville to build a non-hazardous waste processing plant to produce refuse-derived fuel (RDF) at its Alcalá de Guadaira cement plant in Seville. The producer hopes that, when commissioned, the installation will help to 'significantly' reduce the plant's energy costs and CO₂ emissions by substituting its RDF for petcoke in cement production.

Along with a renewal to the Alcalá de Guadaira plant's mining lease, the total cost of the project is Euro6m.

New Zealand: Fletcher Building subsidiary Golden Bay Cement has co-processed 80,000t of waste in production of its EcoSure reduced-CO₂ general-purpose cement at its Golden Bay, Whangarei, cement plant. The plant has achieved a coal substitution rate of 50%. It has processed various waste streams, including 3 million used tyres. EcoSure cement generates CO₂ emissions of 699kg/t of product, 20% less than its imported alternatives, according to Golden Bay Cement. Fletcher building CEO Nick Traber said that this figure is 'simply our starting point.' The company's next target is to achieve a 30% CO₂ reduction by 2030.

Traber said "We needed to think outside the box, or rather the cement bag, to be more precise. The challenge was around what enhancements we could make to our manufacturing processes at our Golden Bay cement works in to improve the plant's sustainability. We quickly realised that consuming used tyres and wood waste as alternative fuels was a win-win. When we started with the idea in 2015, we were aiming to replace 15% of coal with end-of-life tyres. Fast forward to 2022, and our rate of coal substitution is now at 50%, which has obviously delivered further reductions in carbon emissions, as well as helping to offset increased coal costs."
