France: Housing developer Ouest Réalisations has awarded a supply contract to Hoffmann Green Cement Technologies. Under the terms of the agreement, the producer will provide the housing developer with its clinker-free low-carbon cement made from blast furnace slag using its H-UKR technology. The order covers a total volume of 75,000m3 of concrete manufactured by concrete plants distributing Hoffmann Green cement, equivalent to 20,000 - 30,000t of cement, for use in Ouest Réalisations’ developments until the end of 2025. These include the 700-unit Batignolles 2025 project in Nantes and the 103-unit La Croix Blanche project in Les Sables d’Olonne.

Hoffmann Green Cement Technologies co-founders Julien Blanchard and David Hoffmann said "This five-year order commitment once again strengthens the value of our carbon-free cement solution. We are very proud to conclude our first partnership with a housing developer, and all the more so with Ouest Réalisations, a Vendée company with whom we share many values and in particular a common vision: that of decarbonising the new housing construction sector. We are looking forward to following Ouest Réalisations’ real-estate programs using our technology."

Canada: Carbicrete has secured US$1.5m in funding from US-based SQN Venture Partners (SQNVP). The funds will finance research and development activities at its new Lachine laboratory, as well as operations at its Drummondville pilot plant in Quebec. It said that this brings its total funding received from major investors in 2020 to US$8m with investment already agreed from Harsco Environmental, the Quebec Ministry of Energy and Natural Resources and Sustainable Development Technology Canada (SDTC). The technology company is developing concrete products made with steel slag for the construction industry.

Chief executive officer (CEO) Chris Stern said, “This venture debt cash injection following our equity financing further underlines the thesis that the financial markets are believing in value-added, carbon-negative technologies such as CarbiCrete that mitigate CO₂ in our atmosphere. We are proud to have SQNVP as an investor in our company.”

Australia: Adbri subsidiary Cockburn Cement has approved a US$152m upgrade to its Kwinana grinding plant in Western Australia that includes a slag feed system. It says the investment will consolidate the cement operations at its Kwinana site. At present clinker is transported by truck from the Kwinana Bulk Terminal to cement mills at both the Kwinana grinding plant and the company’s integrated plant at Munster. It will increase its production capacity to 1.5Mt/yr from 1.1Mt/yr at present. The project is expected to save the company US$15m/yr due to better energy, transport and maintenance efficiency when the plant is commissioned by mid-2023. The producer will fund the investment through existing debt facilities.

The upgrade project includes: a bulk materials conveyor linking the Kwinana Bulk Terminal (KBT) facility to a new 110,000t clinker storage shed, incorporating an automated reclaim system, to eliminate road transport and minimise clinker handling using mobile equipment; a slag feed system that will handle granulated blast furnace slag and additives such as gypsum and limestone; a ball mill circuit with the installation of two new cement mills capable of grinding slag and clinker; and a new 21,000t finished product storage, truck loading and weighbridge infrastructure for storage and despatch.

Netherlands: India-based Tata Steel has announced a planned total investment of Euro300m in environmental upgrades to its IJmuiden, Noord Holland plant. The upgrades include a Euro150m nitrous oxides control (DeNO_x) plant at its pellet plant and a Euro50m odour, particulate emissions reduction modernisation of a coke and gas plant and projects to dust from converter slag processing. The steel producer says that these measures, called Roadmap+ will help the foundry to ‘exceed environmental laws.’

European regional chief executive officer (CEO) Henrik Adam said, "Tata Steel is taking additional action to build on its Roadmap 2030 plan with the announcement today of Roadmap+, which will enhance the environment in and around the IJmuiden plant. We are absolutely committed to sustainability as a strategic priority across the company, of which these measures are the latest example.”

Slovenia: Steel producer SIJ Acroni has partnered with construction company Batt Crew, non-governmental organisation (NGO) Dejmo, the Olympic Committee of Slovenia Association of Sports Federations (NOCSLO) and the Slovenian Steel Group for a “one-of-a-kind” project to construct five Olympic standard pump tracks – jump circuits for BMX bikes – from steel slag.

The company will supply 10,000t of black slag in various grain sizes to five sites across the country, and all of the tracks are scheduled for completion in 2022. The partners share “one common vision: to have a pump track in every municipality,” according to the producer. It said that the project “follows the principles of circular economy, because it creatively uses slag, a by-product of steel production, to build pump tracks. It enables the partners in the project of sports infrastructure for all to contribute towards reducing the consumption of natural resources.”

SIJ Group senior vice-president Tibor Šimonka said, “The 20 outdoor gyms, which were development and built by the efforts of our colleagues, will soon be joined by five slag pump tracks constructed by us and our partners, where members of the local communities all across Slovenia will be able to test their minds of steel."
