Germany: ScrapeTec will present its latest generation DustScrape dust management system at the SOLIDS Dortmund bulk handling technologies exhibition in Dortmund, North Rhine-Westphalia. ScrapeTec says that the new model boasts increased box robustness and is specifically designed for use in closed transfers with high material pressure. It works without the use of energy and also saves energy by enabling users to switch off existing dust extraction systems.

Germany: Holcim has signed an agreement to acquire FDT Flachdach Technologie (FDT), a leading manufacturer of thermoplastic roofs. FDT has a presence in European markets, with net sales of Euro50m in 2022. Holcim says that, as a technology and sustainability leader in its sector, FDT will complement Holcim’s integrated roofing product range and strengthen the geographical footprint of the business.

With this acquisition, Holcim roofing systems will exceed US$4bn in net sales ahead of schedule. Chief executive officer Jan Jenisch said “By acquiring FDT we are further expanding our Solutions & Products business to become a global leader in roofing systems. Due to its leadership in technology and sustainability, as well as its strong customer relationships, FDT will be a cornerstone of our continued expansion into the most attractive European roofing markets. I am excited to further grow and strengthen FDT’s business and welcome all 180 employees to the Holcim family.”

Germany: Aumund Group has reported that its chair Franz-Walter Aumund died on 4 February 2023. He was 78 years old. He was the third generation of the Aumund family to run the company after his grandfather Heinrich Aumund founded Aumund Patente in 1922.

A farewell ceremony will be held at Aumund Group’s headquarters in Rheinberg, North Rhine-Westphalia, on 14 February 2023.

Germany: Beumer Group is preparing to exhibit at the Solids Dortmund trade fair on 29 – 30 March 2023. The supplier will be showcasing its equipment for conveying, loading, palletising and packaging various bulk materials for the cement, building materials and chemical industries. Solids Dortmund covers equipment for granules, powder and bulk solids technologies.

Cemex launched a new waste management division called Regenera this week. Cemex describes Regenera as a “business that provides circularity solutions, including reception, management, recycling, and coprocessing of waste.” The Mexico-based company has a long and leading history with sourcing and using alternative fuels in the cement sector and the new organisation looks set to utilise this experience. What is notable though is how the business is targeting three waste streams: municipal and industrial; industrial by-products; and construction, demolition and excavation waste (CDEW). Bringing the three waste streams together in this way appears to be novel for the heavy building materials sector, particularly the inclusion of CDEW, which we will explore further here.

CDEW is split into fractions, just like the municipal and solid waste streams that end up as alternative fuels at cement plants, but the biggest fractions are generally concrete, followed by bricks. The recycled concrete is then typically used as an aggregate, either in new concrete production or in areas like road construction and earthworks. The use of recycled aggregates (RA) made from CDEW goes back to at least the 1930s in its current form although ‘reusing’ materials from structures such as castles and churches goes back far further. Recycling and reusing CDEW gained a boost in 2020 when the European Union (EU) set a 70% recovery target. However, within the EU the CDEW recycling rates vary considerably and that 2020 target includes the use of CDEW in backfill applications.

In its launch statement for Regenera, Cemex noted that it operates a dock in Paris, where it receives a variety of materials, including construction debris, excavated material and inert soil. These materials are sorted, processed and then transformed into recycled aggregates or organic material used to restore quarries. Cemex then promptly followed up the official launch of Regenera on 30 January 2023 with the acquisition of a majority stake in Shtang Recycle, an Israel-based CDEW recycling company. It added that Shtang Recycle is preparing to build a recycling plant with a production capacity of 0.6Mt/yr of CDEW waste materials. The output from the plant will be used as raw materials for aggregate production.

The focus on CDEW recycling was flagged up at Cemex’s investor event in November 2022. It said that it was targeting a recycling rate of 14Mt/yr of construction and demolition waste by 2030. Other managed waste stream goals included doubling the amount of municipal and industrial waste it manages, to achieve a 50% to fossil fuel substitution rate, and increasing its usage of alternative raw materials and by-products by 30%, thereby eliminating 13Mt/yr of extracted materials.

Cemex is not alone in targeting the CDEW waste sector. Holcim’s recent work in the area goes back to at least 2016 when a recycling unit near its Retznei cement plant in Austria started processing 130,000t/yr of CDEW. It announced in December 2022 that it was setting up a similar recycling centre, also in Austria, at its Mannersdorf cement plant. In October 2022 Holcim acquired Wiltshire Heavy Building Materials in the UK. This company recycles 150,000t/yr of construction and demolition waste into aggregates and concrete. Holcim linked the acquisition to its Strategy 25 target of recycling 10Mt/yr of construction and demolition waste by 2025.

Activity by other cement companies includes the commissioning of a construction waste recycling plant at Gennevilliers in France by CRH-subsidiary Eqiom in April 2022. It was aiming for a target of 50,000t in 2022. In November 2022 Heidelberg Materials agreed to acquire RWG Holding based in Berlin, Germany. Then, in December 2022, it announced a deal to buy Mick George Group in the UK. Both proposed acquisitions are subject to competition authority approval. Heidelberg Materials’ current target is to offer circular alternatives for half of its concrete products by 2030.

The moves by the bigger cement companies into the CDEW sector follow sustainable thinking and the waste hierarchy. Yet the big prize here is to gain a route to dispose of some of their CO₂ emissions through recarbonation and this has been flagged up in several net-zero roadmaps for the cement sector such as those by Cembureau and the Global Cement and Concrete Association (GCCA). Holcim has been involved in the FastCarb project in France, running a pilot at its Val d’Azergues cement plant in 2021. Heidelberg Materials has been testing its own process with so-called recycled concrete paste. The development now appears to be that utilising CDEW has entered the sustainability strategies for some of the big cement-concrete-aggregate producers, targets have been set and acquisitions are happening.

Germany: Korfez Eng. is supplying internals for a new Ø 4.40m mill shell being installed for an unnamed cement plant in Eastern Europe. All mill internals for this project have been designed and supplied by Korfez Eng. and Korfez Foundry in Türkiye. The total delivery weight of the Korfez supplied mill internal parts exceeds 150t.

Kazakhstan: Germany-based ScrapeTec has signed a deal with Flow Energy to supply its products for the conveyor system of an unnamed client. The agreement will mark the first large-scale entry of ScrapeTec into the Kazak-based mining sector.

Flow Energy is a Kazakhstan–based supplier of pump products that has diversified into providing agitators, filters and crushing and screening equipment. ScrapeTec produces equipment for critical points in conveyor systems that handle bulk handling.

Germany: The Carbon2Business carbon capture project at Holcim Deutschland's Lägerdorf cement plant has received Euro110m in funding from the EU. Holcim Deutschland plans to use the funds to install a new oxyfuel kiln with downstream compression and a CO₂ cleaning unit at the plant in Schleswig-Holstein. The producer expects to commission the upgraded carbon neutral cement plant in 2029.

Germany: The German Cement Works Association (VDZ) has appointed Kristina Fleiger as the head of its new Climate-neutral Process Technology department. Stefan Schäfer has become the head of Environment and Industrial Engineering department. Both posts report to Volker Hoenig, who retains his position as the managing director of the VDZ.

Fleiger has worked for the VDZ in project management and engineering roles since 2011.

Schäfer was previously the VDZ’s Deputy Head of Environment and Plant Technology. He has worked for the VDZ since 1999.
