BNBM grows revenue and profit in 2023
28 March 2024China: Beijing New Building Materials’ (BNBM) operating revenue increased by 11% year-on-year to US$3.10bn in 2023 from US$2.79bn in 2022. Its net profit rose by 32% to US$483m from US$367m. Its sales volumes of gypsum wallboard rose by 4% to 2.17Bnm2 from 2.09Bnm2. This compares to total national sales of 3.21Bnm2. The company is the largest seller of wallboard in China.
The subsidiary of CNBM reported that the country has a wallboard production capacity of 4.95Bnm2/yr, using data from Gypsum Building Materials Branch of the China Building Materials Federation, although 280Mm2/yr of this is classified as ‘backward and uncompetitive.’ It also added that the National Development and Reform Commission proposed in February 2024 that China phase out wallboard production lines with a capacity below 10Mm2/yr as part of the country’s plans to become net zero by 2060.
Indian anti-dumping measures against Chinese and Omani gypsum wallboard to remain in force until end of 2028
11 January 2024Asia: India’s new anti-dumping duty on imports of gypsum wallboard from China and Oman will remain in force for the five-year period up to the end of 2028. The Hitavada newspaper has reported that the duty also applies to gypsum tiles.

Indian trade body recommends five-year anti-dumping duty on gypsum tiles from China and Oman
11 October 2023India: The Directorate General of Trade Remedies (DGTR) has recommended a five-year anti-dumping duty on gypsum tiles imported from China and Oman. Saint-Gobain India initiated the investigation that started in late 2022. It considered gypsum tiles laminated on one side with polyvinyl chloride (PVC) or wax paper that are typically used in ceilings. The study concluded that the product had been “exported to India at a price below the normal value, resulting in dumping.”
Update on gypsum wallboard sustainability, August 2023
31 August 2023One can tell that gypsum wallboard is a popular product because companies keep trying to devise alternatives to it. A recent one is Breathaboard. The company making it, Adaptavate, announced in August 2023 that it had generated around Euro2.3m in its latest investment round. It is building a pilot production line in Bristol in the UK and attempting to licence its Breathaboard product, amongst other plans. Its take on wallboard is being marketed as a sustainable substitute that is made from crop waste, that sequesters CO2 and that then can be composted at the end of its life. It is also promoting the product’s breathability and moisture buffering capabilities, hence the name.
Another new contender hoping to steal some of the gypsum wallboard market is Xeriant’s Nexaboard product. This one uses plastic waste as its alternative to gypsum. Florida-based Xeriant said in July 2023 that it had started to buy equipment and raw materials, was running pilot production and was testing its first samples. It too is working on getting its product used in pilot construction projects.
Both of these examples, and others over the years, have taken a pop at wallboard’s sustainability credentials. Adaptavate is rather quieter about what happens to all of that sequestered CO2 when its product is composted and Xeriant does not mention the environmental impact of making the plastic it uses in the first place. Yet, it is a valid question to ask how sustainable is gypsum wallboard? This column has covered issues with the supply of raw gypsum from either natural, synthetic or recycled sources previously, so we will stick to the general picture here.
The late-lamented consultant Bob Bruce pulled together data from various studies for the Global Gypsum Conference in 2019 to estimate the CO2 emissions from wallboard production. He estimated that the global average of CO2 production by wallboard was around 2.4kg/m2, equating to 24Mt/yr of CO2 for the global wallboard industry. For reference, it is estimated by the Center for International Climate and Environmental Research - Oslo (CICERO) that the process emissions from clinker production alone released around 1.6Gt/yr of CO2 in 2022. When compared by mass (as opposed to area) to other building materials, wallboard has a lower carbon intensity than many products such as glass, cement (made from clinker), plastics, steel and plywood. Timber, concrete and brick are all better than wallboard though. However, as Bruce pointed out, a lot more concrete is manufactured than wallboard. Bruce came up with a handful of suggestions for how wallboard production could reduce its CO2 emissions such as the reduction of slurry water, local delivery, co-generation, increasing drying efficiency and so on.
The two big sustainability trends from the sector over the last year have been the drive to support higher recycling rates of gypsum and a move towards ‘greener’ sources of energy. This can be seen in the growing use of electrical energy from renewable sources such as the production of net zero CO2 gypsum wallboard at Saint-Gobain’s Fredrikstad plant in Norway from April 2023. The group’s Montreal plant looks set to follow in 2024 following an upgrade, potentially making it the first net zero wallboard plant in North America. Chiyoda-Ute in Japan has also started using renewably-sourced electricity at its plants in Japan, but it is uncertain what other energy sources these sites are using. China-based BNBM also claimed in its half-year results that it had built four “nearly zero emission” gypsum board production lines in the reporting period.
Wallboard's market position in North America, Europe and elsewhere seems secure. However, it is in dynamic tension as it is both a potential replacement for more carbon intensive building materials and it could also be susceptible to new emerging products that can improve on its own emissions. The manufacturers of Breathaboard and Nexaboard are clearly hoping for the latter. Yet, as is often pointed out, giving more market share to wallboard from other common building materials could reduce CO2 emissions from construction massively. The diversification of traditional heavy building materials companies such as Holcim into light building materials in recent years suggests that some businesses are seriously preparing for this possibility. No doubt, if global wallboard usage does start to rise significantly, the pressure will grow to make wallboard more sustainable and to devise even more alternative board products.
BNBM’s income and profits grow in the first half of 2023
30 August 2023China: Beijing New Building Materials (BNBM)’s operating income grew by 9% year-on-year to US$1.57bn in the first half of 2023, from US$1.44bn in the same period in 2022. Its net profit increased by 19% to US$251m from US$211m. The company said that it had a total gypsum wallboard production capacity of 3.4Bnm2/yr and that it was the world’s largest gypsum board group.
Parent company China National Building Material (CNBM) reported separately that its total sales of gypsum wallboard remained stable in the first half of 2023, at 1.09Bnm2. It said “The supply of gypsum board is stable, but affected by the weak operation of the real estate market. The demand is insufficient and the operation of the industry is under pressure.” It added that BNBM built four “nearly zero emission” gypsum board production lines in the reporting period.
