Argentina: Geocycle, the sustainable waste management subsidiary of Holcim, has announced an investment of US$1.5m to install a new urban waste treatment line in Villa Carlos Paz, Córdoba. The project will have an initial processing capacity of 38,400t/yr and is intended to modernise the local waste treatment system while advancing a circular economy model.

The new technology will enable municipal waste from Villa Carlos Paz and surrounding towns to be converted into alternative fuels, which will be integrated into cement production. Geocycle said the initiative will help divert waste from landfill, reduce greenhouse gas emissions and partially replace the fossil fuels used in cement manufacturing. The new infrastructure will also reportedly improve waste sorting and conditioning, maximising material recovery and increasing the recovery of usable materials.

In Argentina, Geocycle currently operates three co-processing facilities located in Jujuy, Mendoza and Córdoba, along with a waste pre-conditioning facility, a post-consumer plastics separation station and another facility in the city of Córdoba.

Philippines: Holcim Philippines has signed an agreement with Prime Infrastructure Capital for the supply of refuse-derived fuel (RDF) to its cement plants in Bulacan and La Union. Under the deal, Prime Infra’s subsidiary Prime Waste Solutions (PWS) Pampanga will provide RDF produced from plastic waste converted into alternative fuels through co-processing technology, helping Holcim to reduce its reliance on traditional fuels.

Cara Peralta, market sector lead for waste at Prime Infra, said “It is rare to find like-minded organisations such as Holcim willing to partner with us and make investments in sustainable practices like RDF consumption.”

France: Cement producer Eqiom has inaugurated a €2.5m pilot station for the continuous injection of alternative fuels at its Rochefort-sur-Nenon plant. The new facility enables the injection of wood fines - treated wood residues sourced from local sawmills - directly into the kiln at a rate of 5000t/yr.

The facility has reduced its coal use from 30,000t/yr to 8000t/yr. Currently, more than 70% of the plant’s kiln fuel comes from alternative sources, with the site now targeting 80%. Since the 1990s, the plant has successively used liquid chemical waste, animal meal and solid recovered fuels (SRF), which together accounted for 50,000t in 2024. Eqiom is also developing new cement types with lower clinker content by incorporating more pozzolans, as part of its broader decarbonisation efforts.

Pierre Bernard, Eqiom’s head of cement manufacturing, noted that national cement production fell from 20Mt/yr in 2022 to 15Mt/yr in 2024, equivalent to 1960 levels, due to a decline in construction activity.

Bulgaria: Zlatna Panega Cement, part of Greece-based Titan Group, has achieved a 65% rate of thermal substitution of fossil fuels with alternative fuels for four consecutive months. The company’s 5MW solar plant supplies between 11% and 13% of its energy needs.

General director Adamantios Francis said “We have achieved a historic success for our plant. With this, we prove that we are committed to sustainable development and are ready to lead the industry towards a greener future.”

Titan Group’s long-term strategy includes cutting energy consumption by 58% compared with 2020 levels and reducing direct net CO₂ emissions to 500kg/t of cement. At Zlatna Panega, CO₂ emissions in 2024 were 839kg/t of clinker, while electricity-related emissions fell by 38% year-on-year.
