India: Thiruvananthapuram city Corporation has conducted a trial run of its refuse-derived fuel (RDF) plant at Sanmathi Park, Chala. The plant processes up to 1t/day of legacy waste, which is hard to segregate, to produce fuel for cement plants. The plant processes 40kg of materials per 15-minute cycle. Currently, non-recyclable materials are sent to Tamil Nadu cement plants. The government plans to establish at least one RDF plant per district as a permanent solution.

Mexico: Regenera, a subsidiary of Cemex, has launched a pilot project at its Broquers Ambiental plant in Querétaro to transform the city’s organic waste into alternative fuel using a drying process known as ‘biosecado’. This initiative makes Querétaro the first zero waste municipality in Mexico, according to the company. The plant now processes almost 90% of the municipality’s waste, transforming over 8000t monthly into biomass to reduce the amount of material sent to landfill.

Vice president of urban solutions at Cemex Mexico, Antonio Balmori, said "This project that we started today at our Broquers Ambiental plant excites me very much because it will take the city of Querétaro to the next level in waste management, where we will seek to take advantage of 100% of the urban solid waste generated in the municipality."

Egypt: Cemex has entered an agreement with the authorities in Egypt's Gharbia province to operate the first facility of its circularity solutions business, Regenera. The company will treat over 800t/day of municipal solid waste at the facility to produce alternative fuels and compost, aiming for minimal residual waste to landfill.

"Through Regenera, Cemex seeks to conserve natural resources, reduce greenhouse gas emissions and benefit communities by promoting sustainable development and reducing the environmental impact of industrial activities," the company said.

Brazil: Votorantim Cimentos has inaugurated its first unit in Brazil for Viter, its agricultural inputs business, and Verdera, its sustainable waste management business. Located in Itaperuçu, the unit comprises a new Verdera waste crushing plant and an agricultural limestone production line for Viter. This initiative is part of a US$785m investment programme.

Verdera's Itaperuçu facility has a capacity of 48,000t/yr, tripling its previous capability, and is equipped with technology for sustainable waste treatment. The waste processed at the plant will be converted into clean energy for cement production at Votorantim's plant in Rio Branco do Sul, using co-processing technology developed by Votorantim in Brazil in 1991. Viter's new line will increase agricultural limestone production in Paraná. The Itaperuçu plant, along with the existing Rio Branco do Sul unit, brings Viter's total capacity to 1.5Mt/yr of agricultural limestone in Paraná. The new plant features filters for emission control and utilises biomass as a renewable energy source.

Mexico: Cemex said in its Integrated Report 2023 that its alternative fuel (AF) substitution rate rose to 37% in 2023. The group attributed the rise to its deployment of hydrogen injection technology.

Cemex said “We continued our global roll-out of hydrogen injection technology, and it's now used in half of our cement plants. In Mexico alone, we made sizeable investments installing new hydrogen units and plan to continue scaling hydrogen use in our operations worldwide.”

India: ACC and Ambuja Cements' Geoclean has launched two new facilities for sustainable waste management. The Ambuja Marwar pre-processing and co-processing facility in Rajasthan can convert 220,000t/yr of refuse into alternative fuel, while the ACC Jamul co-processing facility will process an additional 120,000t/yr.

The Ambuja Marwar facility, in collaboration with the Ambuja Marwar Farmer Producer Organisation, aims to source 50,000t/yr of agricultural waste from local farmers. This initiative will also increase the plant's thermal substitution rate to 15%. Similarly, the ACC Jamul facility will enhance its thermal substitution rate to 10%, reducing CO₂ emissions through the co-processing of waste in the cement kiln.

Spain: Cemex España plans to install a new tertiary mill in its Alicante cement plant’s refuse-derived fuel (RDF) line. The project, called Molentis, is scheduled for completion in early 2025 and will cost €6m. The Molentis upgrade will help the Alicante cement plant to raise its RDF substitution rate by 8%, according to the producer. This in turn will reduce its CO₂ emissions by 6700t/yr. The Spanish Ministry of Industry, Energy and Tourism granted €4.4m toward the project to Cemex España under its Innovation and Sustainability Plan.

Cemex España director of operations Benjamín Cabrera said "Molentis will enable us to advance towards climate neutrality and position the Alicante factory at the forefront of new technologies in the decarbonised industry."

France: Vicat aims to process 100% alternative fuels (AF) in its fuel mix across all cement plants in France by 2025. The L'Est Républicain newspaper has reported that the producer recorded a substitution rate of 66% in France in 2022, and of 95% at its Xeuilley cement plant in Meurthe-et-Moselle in the same year.

Europe: The European Parliament voted in favour of multiple amendments to the European Commission’s Packaging and Packaging Waste Regulation (PPWR) on 22 November 2023. The amendments remove, modify or make non-binding the PPWR’s 2040 reuse targets. Meanwhile, 2030 targets were made adjustable to recycling rates. Total packaging volumes are still required to drop by 5% by 2030 and by 15% by 2040 in each member state.

Sustainability lobbying organisation Environmental Coalition on Standards (ECOS) described the introduction of recycling rates into a lower schema of waste targets as ‘comparing apples with pears.’ ECOS attributed the amendments to a ‘barrage’ of false claims, scaremongering and lobbying from industry players.

ECOS programme manager Mathias Falkenberg said “This decision will not sufficiently address rising plastic and packaging waste or the pollution crisis. The European Parliament has just weakened a perfectly feasible solution to tackle throwaway culture without offering an alternative. It is very frustrating that the European Commission’s progressive prevention and reuse agenda has not received full support from the Parliament today.”

ECOS founded the Alliance for Low-Carbon Cement & Concrete (ALCCC), an association of companies focused on alternative building materials production, in May 2023.

France: Lafarge France has ignited the new kiln at its Martres-Tolosane cement plant following a Euro120m upgrade. Local press has reported that the upgrade replaced the plant’s existing kilns and preheater tower with entirely new equipment. The new kiln has tripled the plant’s capacity, to 2.1Mt/yr from 0.7Mt/yr. Meanwhile, the new preheater tower will help to reduce the plant’s electricity consumption by over 20%. As a result of the upgrade, the Martres-Tolosane plant can now support an alternative fuels (AF) substitution rate of 60%, compared to 20% beforehand. Lafarge France aims to carry out further work to reach 85% AF substitution at the plant by 2027. Other planned projects include the installation of a carbon capture system.

Lafarge France CEO François Petry said “We are going to create a research and innovation centre here dedicated to the capture of CO₂, with the ambition of ultimately making the Martres-Tolosane plant net zero carbon.”
