Building codes and low-embodied carbon building materials
15 November 2023Last week the US General Services Administration (GSA) announced that it was investing US$2bn on over 150 construction projects that use low-embodied carbon (LEC) materials. The funding is intended to support the use of US-manufactured low carbon asphalt, concrete, glass and steel as part of the Inflation Reduction Act. For readers who don’t know, the GSA manages federal government property and provides contracting options for government agencies. As part of this new message, it will spend US$767m on LEC concrete on federal government buildings projects following a pilot that started in May 2023. The full list of the projects can be found here.
This is relevant because the US-based ready-mixed concrete (RMX) market has been valued roughly at around US$60bn/yr. One estimate of how much the US federal government spent on concrete was around US$5bn in 2018. So the government buys a significant minority of RMX in the country, and if it starts specifying LEC products, this will affect the industry. And, at present at least, a key ingredient of all that concrete is cement.
This isn’t the first time that legislators in the US have specified LEC concrete. In 2019 Marin County in California introduced what it said was the world’s first building code that attempted to minimise carbon emissions from concrete production. It did this by setting maximum ordinary Portland cement (OPC) and embodied carbon levels and offering several ways suppliers can achieve this, including increasing the use of supplementary cementitious materials (SCM), using admixtures, optimising concrete mixtures and so on. Unlike the GSA’s approach in November 2023 though, this applies to all plain and reinforced concrete installed in the area, not just a portion of procured concrete via a government agency. Other similar regional schemes in the US include limits on embodied carbon levels in RMX in Denver, Colorado, and a reduction in the cement used in RMX in Berkeley, California. Environmental services company Tangible compiled a wider list of embodied carbon building codes in North America that can be viewed here. This grouping also includes the use of building intensity policies, whole building life cycle assessments (LCA), environmental product declarations (EPD), demolition and deconstruction directives, tax incentives and building reuse plans.
Government-backed procurement codes promoting or requiring the use of LEC building materials for infrastructure projects have been around for a while in various places. The general trend has been to start with measurement via tools such as LCAs and EPDs, move on to government procurement and then start setting embodied carbon limits for buildings. In the US the GSA’s latest pronouncement follows on from the Federal Buy Clean Initiative and from when California introduced its Buy Clean California Act in 2017. Outside of the US similar programmes have been introduced in countries including Canada, Germany, the Netherlands, Sweden and the UK. On the corporate side members of the World Economic Forum’s First Movers’ Coalition have committed to purchasing or specifying volumes of LEC cement and/or concrete by 2030. Examples of whole countries actually setting embodied carbon emissions limits for non-government buildings are rarer, but some are emerging. Both France and Sweden, for example, introduced laws in 2022 that start by analysing life-cycle emissions of buildings and will move on to setting embodied carbon limits in the late 2020s. Denmark, Finland and New Zealand are also in the process of introducing similar schemes. The next big move could be in the EU, where legislators are considering embodied carbon limits for building materials as part of its ongoing revisions to its Energy Performance of Buildings Directive or the Construction Products Regulation legislations. Lobbying, debate and arguing remains ongoing at present.
To finish, Ireland-based Ecocem spent a period in the 2010s attempting to build a slag cement grinding plant at Vallejo, Solano County, in the San Francisco Bay Area of California. The project met with considerable local opposition on environmental grounds and was eventually refused planning permission. The irony is that slag cement is one of those SCM-style cements that Marin County, also in the San Francisco Bay Area, started encouraging the use of just a few years later. Ecocem held its inaugural science symposium in Paris this week. A number of scientists who attended the event called for existing low carbon technologies to be adopted by the cement and concrete sectors as fast as possible. One such approach is to lower the clinker factor in cement through the use of products that Ecocem and other companies sell. A point to consider is, if Marin County’s code or the GSA’s recent procurement directive came earlier, then that slag plant in Vallejo might have been built. Encouraging the use of LEC building materials by governments looks set to proliferate but it may not be a straightforward process. Clear and consistent policies will be key.
Etex to acquire BGC’s lightweight building materials businesses
12 October 2023Australia/New Zealand: Belgium-based Etex has signed an agreement with building materials company BGC to acquire the latter’s gypsum and fibre cement businesses. The fibre cement business includes the Canning Vale fibre cement boards plant in Western Australia. BGC also operates nine warehouses across Australia and New Zealand. Etex says that the deal expands its activities in the ‘attractive’ local market, with significant growth opportunities. Finalisation is expected in early 2024.
Etex CEO Bernard Delvaux said “This deal is a strategic opportunity for Etex to complement our footprint in Australia and further increase the accessibility of our products and services for customers. This will both reinforce our gypsum wallboard offering and position us well in the growing fibre cement activities through a broad product range and good channel access.”
New Zealand: Fletcher Building says that its subsidiary Golden Bay cement is waiting to embark on a US$119 – 178m course of capital expenditure (CAPEX) investment. However, the group said that it will first require ‘clarity from the government’ on any upcoming changes to industrial CO2 emissions allocations or border adjustments.
CEO Ross Taylor said “Until we get certainty there, we really can’t pull the cord.” He added “There’s a good pipeline of existing stuff which will really start maturing in two or three years, but there’s another really sizeable pipeline beyond that.”
Fletcher Building invested a total of US$182m across its businesses during the 2023 financial year, which ended in June 2023. The Bay of Plenty Times newspaper has reported that the investments are part of the group’s growth strategy for the four-year period up to the end of the 2027 financial year. Planned areas for investments include adding value to the group’s wood products by developing its alternative fuel (AF) capacity. The growth strategy has a budget of US$474m.
Fletcher Building’s sales flat in 2023 financial year
16 August 2023New Zealand: Fletcher Building recorded sales of US$5.07bn during the 2023 financial year, down slightly year-on-year from US$5.08bn in the 2022 financial year. Its earnings before interest and taxation (EBIT) fell by 29% to US$296m from US$419m. The drop in earnings was mainly attributed to additional costs allocated to the New Zealand International Convention Centre and Hobson Street Hotel project. Adjusted for significant items, the group’s EBIT rose by 6% to US$477m from US$452m.
Throughout the year, Fletcher Building’s cement subsidiary Golden Bay Cement co-processed 100,000t of waste as alternative fuel (AF). The producer awarded a bottom ash supply contract to Huntly Power Station. It also launched EcoZero carbon neutral cement, which is its EcoSure reduced-CO2 cement with the remaining emissions offset.
Chief executive officer Ross Taylor said “Looking forward to the 2024 financial year, we expect some further tightening in our overall volumes and so our focus remains on strong customer performance, cost control and pricing disciplines across our businesses. We have shown we are well equipped to continue performing solidly through the cycle.”
Neocrete plans first Neocrete activator plant
24 July 2023New Zealand: Neocrete has launched an investment round to raise over US$1.86m in funding. The start-up will use the funds to build an industrial-scale plant for its Neocrete activator for pozzolan-based concrete. The use of Neocrete's activator can eliminate up to 50% of cement in concrete. Neocrete aims to ultimately displace 100% of concrete's cement content. The Hawke's Bay Today newspaper has reported that pozzolan-based concrete made using Neocrete's additive offers resilience benefits compared to conventional ordinary Portland cement (OPC)-based concrete. It is especially suited construction in seawater-exposed settings.
Golden Bay Cement secures bottom ash supply
09 May 2023New Zealand: Golden Bay Cement has signed a deal with Genesis Energy for a supply of bottom ash from Huntly power plant for use in cement production at its Portland cement plant in Northland. Genesis Energy generates 20,000t/yr of bottom ash at the Huntly plant, situated in Waikato, 260km south of the Portland cement plant. The plant currently uses 15,000t/yr of fly ash from the Huntly power plant in its operations. The producer was previously investigating the use of volcanic ash in cement production in 2022. It currently uses waste tyres and wood waste as alternative fuels (AF) to produce its EcoSure low-carbon general-purpose cement.
Golden Bay Cement's general manager Gian Raffainer said "We are driven to decarbonise and achieve 30% less carbon by 2030. Contributing to waste reduction at a large scale for the benefit of all New Zealanders is incredibly exciting. It is a win-win for the environment and for Kiwis who want to use more environmentally friendly products."
Russia/Uzbekistan: The US Department of State has imposed sanctions upon USM Holding including its subsidiaries Akkermann Cement and USM Cement in Russia, and Akhangarancement in Uzbekistan. The action is intended to target company owner Alisher Burhanovich Usmanov and his various business interests. Other USM companies in the iron, steel, copper, gold, telecommunications and real estate sectors are also affected.
The US Department of the Treasury’s Office of Foreign Assets Control noted that Usmanov was, “one of Russia’s wealthiest billionaires, with vast holdings across multiple sectors of the Russian Federation economy as well as internationally.” It added that he was linked to multiple senior Russian officials, including Russian President Vladimir Putin as well as Dmitry Medvedev, current Deputy Chairman of the Security Council of Russia and former President and Prime Minister of Russia. Usmanov has also been sanctioned by Australia, Canada, the European Union (EU), Japan, New Zealand, Switzerland and the UK.
These latest US sanctions are in response to the Russian invasion of Ukraine in February 2022. Companies on the sanction list are forbidden to conduct business transactions with any US citizens.
Akkermann Cement operates two cement plants and a network of 12 terminals in Russia. It acquired a majority stake in Uzbekistan-based Akhangarancement in early 2022.
Housing demand in New Zealand falls by 20% year-on-year
11 April 2023New Zealand: Cement producer and construction firm Fletcher Building has reported a 20% year-on-year drop in domestic housing demand during the first quarter of 2023. The Australian newspaper has reported that the company attributed the decline to ‘soaring’ interest rates in the country. It now expects to sell 800 residential units in 2023, 20% below its previous expectation of 1000 units. Fletcher Building said that building materials costs rose by 5 – 10% between 2020 and 2022, due to ‘higher input and commodity costs’ in production.
CEO Ross Taylor said that Fletcher Building faces labour shortages in its civil construction business, but maintained a strong order pipeline. Taylor said “It won’t drive an uptick in volumes but it will underpin the volumes in the next three to four years.”
Australia: The Australian Competition and Consumer Commission (ACCC) has called for public comment on Switzerland-based Sika's proposed acquisition of Germany-based fellow construction chemicals producer MBCC Group. The commission has raised 'preliminary concerns' over the possible competition impacts of Sika obtaining an 80% Australian market share as a result of the deal.
Sika group responded to the ACCC's concerns with an offer of an undertaking to divest MBCC Group's entire Australia and New Zealand business.
Fletcher Building’s concrete division joins GCCA
09 December 2022New Zealand: The Global Cement and Concrete Association has welcomed Fletcher Building’s concrete division as its first member from Oceania. Scoop News has reported that the concrete’s division’s business spans the entire concrete value chain, including 26 limestone and aggregates quarries and 80 ready-mix concrete batching plants. Its cement subsidiary Golden Bay Cement operates the 0.9Mt/yr Portland cement plant in Whangārei, New Zealand.
Fletcher Building concrete division CEO Nick Traber said "Fletcher Building firmly believes we can play a significant part in a carbon zero and circular future. Our Golden Bay EcoSure cement is one of the lowest-carbon cements in the world already, with 13 - 22% less embodied carbon than imported products. We believe having access to the global research and knowledge from the GCCA will help us improve this further and continue to lead Australasia in best practice decarbonisation of the built environment."
