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.”

Austria: Loesche subsidiary A TEC has won a contract for the supply and installation of a Flash Dryer for alternative fuels (AFs) in the kiln line of Lafarge Zementwerke's 1.1Mt/yr Mannersdorf cement plant in Lower Austria. The supplier said that it will complete the project in early 2021.

The company said, “Reaching high thermal substitution rates (TSR) requires firing of alternative fuels at the kiln burner. To reach a stable sintering zone for the required clinker quality a high fuel quality (high LCV, small particle size) is needed, otherwise the clinker quality may suffer or the TSR can be limited. With the A TEC Flash Dryer various waste heat sources can be used (clinker cooler flue gas, bypass gas, preheater gas, etc.). The material is dosed to the hot gas flow in the flash dryer and transported with this gas flow, while the moisture is evaporated, to a cyclone and a subsequent filter where the fuel is separated from the gas flow and on-line fed to a kiln burner or a satellite burner. In addition to the drying the lifting effect of the gas can separate 3D impurities which contributes in a further increase of the fuel quality.”

Canada: The Capital Regional District (CRD) in British Colombia has signed a memorandum of understanding with Ḱenes Transportation, a Wsáneć First Nations partnership company, to contract the transportation of biomass produced at a sewage treatment unit at Hartland Landfill to Lafarge Canada’s Richmond cement plant. The dehydrated biofuel made from treated wastewater is then coprocessed as an alternative fuel at the integrated cement plant. The agreement will last up to five years while the CRD develops long term plans for the biosolids, according to the Times Colonist newspaper.

Switzerland: LafargeHolcim says it will double the use of waste derived fuels in production by 2030 from a baseline set in 2018. It made the announcement as it signed the Science-Based Targets initiative (SBTi) Business Ambition for 1.5°C pledge, which commits it to net-zero carbon dioxide (CO₂) emissions by 2050. It says it is the first building materials company to join the pledge.

The company has committed itself to a 20% reduction in its CO₂ intensity between 2018 and 2030. It says that over the period it will: “accelerate the use of low-carbon and carbon-neutral products such as ECOPact and Susteno, recycle 100Mt of waste and by-products for energy and raw materials, scale up the use of calcined clay and develop novel cements with new binders, reach net CO₂ emissions 475kg/t of cementitious material and open and operate its first net-zero CO₂ cement plant.

Chief Executive Officer (CEO) Jan Jenisch said, “I believe in building a world that works for people and the planet. That’s why we are reinventing how the world builds today to make it greener with low-carbon and circular solutions. I am very excited to be working with SBTi, taking a rigorous science-based approach to shape our net zero roadmap and accelerating our efforts to substantially lower our CO₂ footprint. I will not stop pushing the boundaries to lead the way in green construction.”

US: The legislative body of Albany County, New York, has enacted a law ending the establishment of new waste burning facilities. The Times Union newspaper has named LafargeHolcim subsidiary Lafarge North America’s 2.0Mt/yr Ravena cement plant amongst facilities affected. The legislature came to its decision following public outcry after Lafarge North America announced its plans to renew its licence to burn up to 4.8Mt/yr of tyres in January 2019.

Legislator William Reinhardt said, “While most of the attention had been focused on the potential impacts of the law on facilities like Norlite and LaFarge, the real intended point of the legislation is longer term. We want clean air not only today but for the foreseeable future.”

Spain: Switzerland-based LafargeHolcim subsidiary Geocycle has commissioned an UNTHA XR3000C shredder at its Albox waste processing plant in Almeria. The 15,000t/yr shredder will process domestically-produced commercial and industrial waste, including oil- and solvent-contaminated textiles, plastics, paper and cardboard, into fuel suitable for co-processing at any of LafargeHolcim’s five Spanish cement plants. Geocycle Operations Manager Raúl Lannegrand said, “Co-processing is recognised by the United Nations Environmental Programme (UNEP) Basel Convention and the European Commission as a practical, cost-efficient, safe and environmentally-preferred waste treatment method, so it was important for us to make the most of the landfill diversion opportunity we had identified in Spain.”

El Salvador: Switzerland-based LafargeHolcim subsidiary Holcim El Salvador has announced that it substituted 26,000t of refuse-derived fuel at its 1.7Mt/yr integrated El Ronco cement plant in Metapán, Santa Ana department, in 2019, up by 30% year-on-year from 20,000t in 2018.

In 2019 Holcim El Salvador produced 1.2Mt of cement. The company is currently investigating the possibility of installing a US$5m solar power plant at the El Ronco cement plant. It has signalled an intention ‘in the long term’ to resume operations at its 1.6Mt/yr Maya cement plant, mothballed in 2008, at an estimated cost of US$20m.

Argentina: Geocycle Argentina has appointed Mariano Bollo as its national manager. He is a chemical engineer and holds an MBA from the Catholic University of Salta, according to the El Diario de Carlos Paz newspaper. He began his career at Holcim Argentina in 2006, holding roles at its plants in Jujuy, Mendoza, Córdoba and Buenos Aires.

US: The debate over proposed clean air regulations which may restrict or halt LafargeHolcim’s tyre-burning plans at its 2.0Mt/yr Ravena plant will take place on 23 December 2019. The Times Union newspaper has reported that councillors will debate whether to lower the maximum permitted pollutant emissions from incineration facilities to a level below that entailed by LafargeHolcim’s alternative fuel (AF) plans.

In mid-2018, LafargeHolcim’s licence from the New York State Department of Environmental Conservation for the combustion of 4.8M tyres per year expired. It announced ‘preliminary discussions’ with tyre suppliers in January 2019.

Poland: Figures from the Polish Cement Producers’ Association (SPC) have shown a 30% reduction in specific CO2 emissions over the 30-year period from 31 December 2019 to the projected figure for 31 December 2019 due to the co-processing of alternative fuels (AFs) by cement producers in the country. It estimated a total cost of investments of Euro2.34bn but said that further developments would be slowed in the absence of governmental action to raise electricity and emissions costs for more pollutant competitors.

Lafarge Poland leads the pack in terms of AF substitution, meeting 75% of its fuel needs (0.4Mt/yr) with prepared unrecyclable refuse-derived fuel (RDF). The company says it will increase this figure to 0.5Mt/yr in 2022. Speaking of the planned 25% increase, Lafarge Poland president Xavuer Guesnu said “Concrete and cement products need not be a problem, but rather a solution to contemporary challenges both urban and climatic.” The LafargeHolcim subsidiary operates a 0.2Mt/yr RDF processing plant at its 2.0Mt/yr integrated Kujawy w Blelawach cement plant.
