Canada: Progressive Planet is preparing to build a 3200t/yr pilot plant for its PozGlass product at its headquarters in Kamloops, British Columbia. The company aims to commercialise its process, which produces pozzolan from recycled glass for use in cement or concrete production. The pilot unit will also sequester CO2 released by a gas dryer at the site, from which it will produce sodium carbonate. The pilot plant is expected to go under construction in 2023 and be operational in 2024.
Steve Harpur, the chief executive officer of Progressive Planet, said “With PozGlass, a CleanTech breakthrough from our C-Quester Centre of Sustainable Innovation in Kamloops, we are producing one of many upcoming private-sector solutions that are needed to meet the 2050 Net Zero targets to fight climate change.”
Progressive Planet aims for PozGlass production to be situated at cement kilns, where PozGlass could be mixed with Portland cement at a 50:50 ratio.
Titan Cement buys share in Aegean Perlites
14 February 2023Greece: Titan Cement has acquired a share in Aegean Perlites. The company operates perlite and pozzolan quarries on the island of Yali. It also has access to port facilities. Titan Group says it is making the investment to gain direct access to pozzolan reserves to increase its volume of pozzolan-based cementitious products with a lower clinker factor. The deal is connected to Titan’s target to reduce its CO2 emissions by 35% by 2030, compared to 1990 levels, and increase the share of green products in its portfolio to over 50%.
Yanni Paniaras, the Group Executive Director Europe of Titan, said “We are pleased to partner with the Govdelas family as joint shareholders in Aegean Perlites, building on our excellent long-term collaboration and aiming to grow our business, maximising the high potential of the Yali pozzolans.”
Unacem Perú to 'significantly increase' cement capacity
23 January 2023Peru: Unacem Perú plans to 'significantly increase' its cement production capacity 'in the medium-term future.' Prior to that, the producer will invest US$130m in capital expenditure during 2023, double what it invested in 2022. The investments will go towards slightly expanding the producer's capacity from 8.3Mt/yr and increasing alternative raw materials use in its cement production, including pozzolan and ground granulated blast furnace slag (GGBFS). Additionally, it will open its new Manchay limestone quarry in Pachacámac in early 2023.
Unacem said that it increased its cement sales 'unexpectedly' during 2022. It operated at 85 - 90% capacity utilisation, and continued to export clinker.
MDG America supplies bucket elevators for Drake Cement's Paulden cement plant upgrade
19 October 2022US: Bulk material handling equipment supplier MDG America says that it delivered four chain bucket elevators for Drake Cement's upgrade of its Paulden cement plant in Arizona. Drake Cement installed a new vertical mill grinding plant for cement, granulated blast furnace slag (GBFS) and raw materials grinding at the 0.7Mt/yr integrated plant. The supplier says that two of the elevators will work in a pair, conveying material from a feeder belt, while a third will convey it to the new mill. The fourth elevator will then collect the material for further grinding and metal discharge.
Drake cement secured approval to mine pozzolan for use in the Paulden's plants cement production at Bill Williams Mountain earlier in October 2022. As part of minimising the future mine's impacts, Drake Cement has offered to help the US Forestry Service to thin local woodland as part of local anti-fire management efforts.
India: Four UltraTech Cement cement products have received Environmental Product Declaration (EPD) certification. UltraTech Cement's ordinary Portland cement (OPC), Portland pozzolana cement (PPC), Portland slag cement (PSC) and Portland composite cement (PCC) all successfully underwent lifecycle assessment studies in line with EPD requirements.
The Aditya Birla subsidiary said that 70% of its cement sales consist of blended cement. It offers over 70 different GreenPro certified products across its range.
Italy: Buzzi Unicem has obtained technical evaluation certification for CEM II/C-M Portland composite cement products to be manufactured at its Trino, Vernasca, Settimello, Guidonia, Barletta and Augusta plants. The new cements will be part of its C-Green product line and the sustainability objectives from its 2030 roadmap. The new products will reduce their clinker factor by using granulated blast furnace slag, fly ash, pozzolan and limestone. They potentially offer up to a 40% reduction in CO2 emissions per tonne compared to CEM I equivalents. They will be available in 32.5 N/R and 42.5 N/R strength classes for a range of applications. The cement producer hopes that the new products will quickly establish themselves in the market and even becoming the “standard cement” in Italy by 2030.
UK: Aggregate Industries and Coomtech have partnered to develop low-energy kinetic drying technology for pulverised fuel ash (PFA) from power plant. The partnership will see Aggregate Industries use Coomtech’s kinetic dryers in its PFA processing, as part of its effort towards increasing the volume of waste materials incorporated in its products to 3Mt/yr from 1.5Mt/yr by 2025. The project has attracted funding from the UK government Department of Business, Energy and Industrial Strategy (BEIS).
Chief commercial officer Chris Every said “We’re delighted to have the support of Aggregate Industries in this grant project. Coomtech is especially pleased to have the business’ ongoing technical and commercial input to the project operation and analysis of performance. In addition, the opportunity to work together with a brand that is leading the way in creating new materials that will prove fundamental to the future of the construction sector and meet net zero objectives.” Every continued “The added benefit of our new drying technology is its flexibility - providing the potential to dry a wide range of materials being considered to aid the greening of the cement industry, including limestone, ground blast furnace slag (GBFS), natural pozzolans and other crushed and milled minerals that can offer an activated character to combine in cement and concrete mixes.”
Eco Material Technologies opens pozzolan mine
23 June 2022US: Eco Material Technologies, a producer of sustainable cementitious materials, has opened its Kirkland Pozzolan Mine in Yavapai County, Arizona. The 40-hectare site is one of the largest natural pozzolan mines in the US.
"We are excited for the opening of the Kirkland Pozzolan Mine, which will benefit not only Yavapai County but all of Arizona as well as the surrounding region," said Grant Quasha, CEO of Eco Material Technologies. "Without the support of elected officials, including Governor Doug Ducey, Senator Mark Kelly, State Senator Karen Fann and State Representative Quang Nguyen, we would not be celebrating this milestone achievement."
The event also recognised the hard work and dedication of the plant's employees, as well as Eco Material's contributions to the area including bringing wireless internet service to the surrounding community, planting new trees and generating significant tax revenue for the state.
Saudi Arabia: Al Kifah Ready-Mix & Blocks (KRB) has announced the upcoming launch of its ConGreen reduced-CO2 concrete products range at the Big 5 Saudi construction summit on 28 – 31 March 2022. ConGreen concretes replace clinker with lower-carbon materials such as pozzolan and use Canada-based Carbon Cure Technologies’ embedded recycled CO2 technology to reduce its carbon footprint by up to 30% compared to conventional ordinary Portland cement (OPC) concretes. In addition to this, KRB says that ConGreen concretes also provide improved workability and pumpability properties, as well as being highly durable, with high passing and finishability. They have very low rapid chloride permeability (RCP), water absorption and water permeability properties and low heat of hydration.
General Manager Nigel Harries said “We are committed to driving energy efficiency and addressing the global emission challenges. We aim to help build a better community and environment-friendly facilities by producing high-quality concrete, such as ConGreen, that has a reduced environmental impact and is characterised by its high performance, durability and sustainability, with a low carbon footprint as compared with standard concrete.”
