France: Vicat started using a CO₂ntainer system supplied by UK-based Carbon8 Systems at its Montalieu-Vercieu cement plant in November 2020. It uses captured CO₂ from the unit’s flue gas emissions to carbonate cement-plant dust and produce aggregate, which can then be used to make products such as concrete. The system has particular relevance for a plant burning alternative fuels due to the additional chlorinated dust created compared to the use of conventional fossil fuels. The company says it is the first European cement producer to use the process at an industrial scale. Previously, Carbon8 Systems said that its CO₂ntainer would process and convert up to 12,000t of cement bypass dust in its first phase of operation.

Vicat Group scientific director Laury Barnes-Davin said, “We were drawn to Carbon8 Systems’ two-part technology: capturing the CO₂ that Montalieu emits, and using it to produce an aggregate that can be marketed in the construction industry. It opens up great potential for our operations not just in France but also in all the countries where we work across the globe.” The group hopes to reach a 100% alternative fuel substitution rate in France by 2024.

Argentina: LafargeHolcim waste management subsidiary Geocycle has begun shredding waste at its Córdoba co-processing plant using a new Untha XR3000C one-step shredder supplied by Austria-based Untha. The shredder will produce refuse-derived fuel (RDF) for use at LafargeHolcim’s Córdoba cement plant. It is the 10th Untha shredder Geocycle has commissioned.

Director Mariano Bollo said, “Geocycle Argentina is no stranger to waste shredding for alternative fuel (AF) production. We previously used a dual-shaft machine manufactured by a competitor of Untha’s, but the capacity and reliability of our machine continued to cause us problems. Untha’s low speed, high torque drive means this is a powerful machine with impressive uptime, ease of maintenance and proven capabilities. This – combined with the shredder’s versatility – meant the business case to switch to an XR was strong. While we think carefully about every decision we make, to ensure each shredder we invest in has absolutely the right configuration for every single plant, we now run a number of Untha machines across our global group,” continued Mariano. “The whole life operating costs of this shredder are extremely low, which means we can consistently produce a profitable, environmentally-sound fuel. It therefore comes as little surprise that we’re looking to standardise the technology we use across our business. This has benefits when it comes to procuring and sharing spare and wear parts too. Working in collaboration with Untha’s local engineering specialists, Geocycle is now optimising the design and layout of the waste processing line to double throughputs in early 2021. This XR investment aligns with our global AF production strategy, which doesn’t just improve our cement manufacturing footprint worldwide – it transforms the environmental status of our local communities too.”

US: Veolia North America (VNA) has signed a contract for the supply of used blades from onshore wind turbines from GE Renewables. The waste management company will process the blades to produce shredded composite materials for use in cement production, both as replacement for war materials such as sand and clay and as an alternative fuel. As a part of the agreement, blades that have been removed from turbines will be shredded at VNA’s processing facility in Missouri and then used in cement plants across the US. On average, nearly 90% of the blade material, by weight, will be reused as a repurposed engineered material for cement production.

Environmental solutions and services chief operating officer (COO) Bob Cappadona said, "By adding wind turbine blades — which are primarily made of fibreglass — to replace raw materials for cement manufacturing, we are reducing the amount of coal, sand and minerals that are needed to produce the cement.” GE Renewables and sustainability consultant Quantis said that the use of turbine blades in cement production would reduce net CO₂ emissions by up to 27% and water consumption by up to 13%.

Philippines: Aboitiz Equity Ventures and CRH subsidiary Republic Cement says that it is seeking partners to supply it with plastic waste, which it can co-process as refuse-derived fuel (RDF). The Business World newspaper has reported that the company has set a target of 10m plastic bags/day by 2021.

President and chief executive officer Nabil Francis said, “We would like to commit to a very ambitious target next year, and this target is to co-process not less than 10m equivalent of plastic bags/day, starting from the very beginning of next year.” Angela Edralin-Valencia, the resource recovery director of Republic Cement’s Ecoloop division, said, "It's going to be double what we are currently doing, and it's just the beginning.”
