Winstone Wallboards has been in the spotlight in recent months over ongoing supply issues of gypsum wallboard in New Zealand. Many places around the world have suffered from similar shortages of building materials following the coronavirus lockdowns. However, the shortages in New Zealand have started to generate a considerable response, as we detail below.

Rightly or wrongly, Winstone Wallboards’ dominance in the market locally has been perceived as part of the problem. It operates the country’s only two wallboard plants and it is frequently reported to hold around a 95% share of the market. It is also currently building a new 10Mm²/yr gypsum wallboard plant at Tauriko near Auckland. Commissioning is planned for mid-2023. Once completed the company will have a total national wallboard production capacity of around 40Mm²/yr.

The current problems date back to the start of the coronavirus pandemic when New Zealand started implementing its lockdowns and residential renovation work increased. The issue then gained prominence in September 2021 when Winstone Wallboards started issuing regular supply updates on its website as the government began to relax the lockdown at that time. It says that order volumes more than doubled from November 2021 to February 2022 as customers started to bring forward their orders to cope with general building material shortages. It coped for a while by using its inventory stock and by bringing in imports from Australia but the latter stopped in November 2021 due to shortages there also. So it proposed introducing an allocation model from July 2022 whereby customers could place orders no more than one month in advance. It then says it worked on increased output through plant and process upgrades with the installation of a heat exchange system for its Auckland plant planned for July 2022 and by securing further imports from an Australian producer for the second half of 2022. As of late June 2022 it expected the market to return to equilibrium by October 2022.

Unfortunately, some consumers have been vocal about their unhappiness with the supply situation. Rental property developer Simplicity Living took to the press to complain about the delays in June 2022. It added that it had started importing its own wallboard from Thailand instead. The story then became nastier when Simplicity Living alleged that Winstone Wallboards’s parent company, Australia-based Fletcher Building, was blocking imports of certain colours of wallboard. Fletcher Building clarified in the same article that it had trademarked “specific” shades of blue, green, mauve and pink to differentiate its products in the marketplace. This, of course, will be familiar to insulation sector readers of Global Gypsum as Owens Corning is arguably the world’s most famous and successful example of how to copyright a colour. It’s unclear how much of an impediment Fletcher Building’s colour trademarks have been to imports to New Zealand. The company did say in an investor presentation in late June 2022 that it had granted 10 trademark royalty-free licenses so far to allow other companies to import wallboard. To give readers an idea of the amount of attention being focused on Winstone Wallboards and its connected companies, when a shipment of wallboard was delivered early to a construction subsidiary of Fletcher Building, apparently breaking the company’s own supply rules, a video of the incident started circulating on social media before being picked up by national news channels.

Government oversight then stepped up a notch in late June 2022 with the formation of a ministerial taskforce to tackle the wallboard shortage. It plans to troubleshoot the regulation of alternative plasterboard products, look at ways to streamline the use of products that are currently untested in the New Zealand market, provide advice on building consent and explore new distribution models, amongst other goals. Alongside all of this, the New Zealand Commerce Commission started a market study into residential building supplies in November 2021. Its aim is to look into any factors that may affect competition for the supply or acquisition of key building supplies. A draft report for consultation was scheduled for release in July 2022 and the final report should be due in December 2022.

Winstone Wallboards’ woes are clearly down to the disruption caused to supply chains by the coronavirus pandemic. However, fairly or unfairly, its local market dominance has exposed it to most of the blame for the situation in the eyes of some of the New Zealand public. Its products are so integrated into the usage of wallboard in the country, for example, that the Gib brand is specified by name in many of the region’s building consent application documents. The government has now become involved adding further to the public scrutiny. Structural changes may or may not be required at some or multiple levels of the New Zealand wallboard market to fix the current crisis. Yet, funnily enough, in one interview Fletcher Building chief executive officer Ross Taylor raised the issue of customers developing the ‘fear factor’ in response to hearing about shortages and then buying more than they might need. This may sound familiar because it is exactly what happened at the start of the worldwide coronavirus lockdowns when people started panic buying toilet-roll. Whatever else is happening in New Zealand, human nature can’t be helping either.

BNBM has announced two overseas gypsum wallboard plants since the start of 2022. In Early January 2022 the China-based producer said it was going to build a 40Mm²/yr plant in Thailand as part of a joint-venture with Sinoma International Engineering and its subsidiary Sinoma (Thailand). Notably the unit is also to be equipped with a decorative gypsum line. The estimated project investment is US$55m. Then, in February 2022 BNBM revealed plans to build a 40Mm²/yr gypsum wallboard plant in Bosnia & Herzegovina. This one is a joint venture with Rudnik i Termoelektrana Ugljevik (RiTE Ugljevik), a subsidiary of the local state-run power company. The project will be situated next to the coal-fired power plant at Ugljevik. No surprises then for what source of raw gypsum the wallboard plant is likely to be using! The estimated project cost is Euro50m.

These two projects join a pair of other plants the producer is also cooking up internationally. In mid-2019 it revealed new wallboard plants in Tanzania and Uzbekistan. The former is a 15Mm²/yr plant to be run via a subsidiary. It was reported to be in a construction phase in mid-2021. The latter is a 40Mm²/yr gypsum wallboard plant to be built in the Kokand Free Economic Zone, Fergana Region in Uzbekistan via a wholly-owned subsidiary. So far it is reportedly in the preparation stage. The company also has a number of wallboard plant projects in development at home in China, including plants currently being built at Shuozhou in Shanxi province and Yichang in Hubei province.

During the first half of 2021, BNBM’s operating income rose by 46% year-on-year to US$1.59bn from US$1.09bn. 65% of this was generated from its gypsum wallboard business sales. Overall, parent company CNBM reported gypsum wallboard sales of 2.01Bm2 in 2020 from BNBM and Taishan Gypsum.

A subsidiary of CNBM building production capacity outside of China will sound familiar to those readers who follow the cement industry. The industry has been using the Belt and Road Initiative to move redundant domestic capacity abroad as the local market has become saturated and environmental measures bite. Chinese cement production capacity per capita has seemed extraordinarily high by international norms over the last 20 years. Yet, gypsum wallboard production capacity per capita is a wildly different story. Global Gypsum Directory 2021 data suggests that the US had a rate of 12.7m²/capita compared to 2.4m²/capita in China.

With this in mind it makes one wonder why BNBM is bothering internationally given the market scope at home as China meets its climate commitments. As the move by some western multinational building material companies over the last year or so suggests, the future may lie in light building materials. On the other hand BNBM/CNBM may simply have its eye on the bigger picture. Just like its international competitors, it doesn’t want to miss out on the opportunity for market enlargement or being left behind if the ratio between heavy and light building materials switches. If it really means business, then the next steps could be wallboard plants in Western Europe or even the US. A US-based joint-venture for BNBM might help to make everyone forget the unending legal debacle with Taishan’s imports.

Members of Eurogypsum, the European Gypsum Association, gathered at the Les Atelier des Tanneurs in Brussels on 27 - 28 April 2022 to formally celebrate the 60th Anniversary of their association, despite a delay of 12 months due to Covid restrictions. Over two days, they participated in meetings and panel sessions reminiscent of pre-pandemic times. Attending the Open Congress session on 28 April 2022, Global Gypsum found the event to be very dynamic and surprisingly open.

The Open Congress began with welcomes from the moderator, Knauf Insulation’s Sian Hughes and outgoing Eurogypsum President Emmanuel Normant, of Saint-Gobain. He introduced the past 60 years as one of ‘enormous change’ for the sector, but this was not meant to be a retrospective. Turning to the next 60 years, Normant said that gypsum’s inherent benefits, including its low embodied CO₂ emissions, recyclability, high degree of safety and ease of use, would make it even more crucial to global development in the future than in the past.

A series of quick-fire presentations from the industry’s big hitters then highlighted a wide range of ways to increase the sustainability of our sector.

Saint-Gobain’s Klaus Birk introduced Gyproc's project to switch its Fredrikstad wallboard plant in Norway to use a 100% electric wallboard production process by 2023. This will use renewable energy, predominantly sourced from hydroelectric power, and lead to a 70% drop in CO₂ emissions. This approach could be applicable to any wallboard plant with access to sufficient renewable power.

Knauf's Jörg Demmich then spoke about a project to extract gypsum from the ‘waste’ from the lithium production process. Even the best lithium ores only contain 3 - 6% lithium by mass, leaving 94 - 97% currently unused. As electric mobility grows, by-product gypsum from the lithium sector could partly offset the expected fall in flue-gas desulphurisation (FGD) gypsum supplies.

Iryna Yermakova introduced the Etex Group's approach to the wallboard plant of the future. One area she highlighted was the potential for prefabrication at the wallboard plant before panels reach the job site. This has the potential, on some projects, to save up to 10% of the wallboard cost, transport cost and CO₂ emissions of the board used. Surely a quick win for contractors.

Nikolai Halle from Cobuilder introduced the Define tool, freely-available to the construction sector. Define will act like the Swift payment system, but for sustainability data instead of financial data. This would unify different sustainability metrics to cut through the confusing terms used by producers and reveal the 'real' performance of different products, rather than how effectively their attributes are marketed.

The keynote presentation, from the former European Commissioner for the Environment Janez Potočnik – ‘The Father of the Circular Economy’ - then highlighted why innovation is key, not only to the future of the gypsum sector, but to the planet itself. At current rates, the mass of man-made material will be three times larger than all biomass by 2040.

To avoid this, Potočnik argued that the entire economy needs to become service-based, rather than product-based. Under such a model, wallboard producers would become part of the ‘building envelope services sector’ rather than selling wallboard. The desire is then to sell wallboard with a long service life, that can be repurposed and recycled, rather than selling ever-increasing volumes of board.Taking this approach across the entire economy would help society to maximise gross domestic product while reducing environmental impacts, eventually decoupling them from each other entirely. Potočnik concluded that nature is already the 'perfect' circular economy. Humans just need to reintegrate into it.

To say that the panel discussion that followed was ‘lively’ would be an understatement. Member of the European Parliament Iskra Mihaylova, speaking the day after Russia halted gas supplies to her native Bulgaria, said that talk of energy independence and solidarity was 'not enough' and that Europe needed to act on the European Union Green Deal, particularly with a view to energy and resource efficiency and security.

Josefina Lindblom, the European Commission’s Policy Officer for Sustainable Buildings for Circular Economy, introduced what she hoped would become the next buzzword: ‘sufficiency’ - properly taking pause to consider what is truly required of new buildings. This includes the need to apply full circularity to renovation projects.

Adrian Joyce, from the European Alliance of Companies for Energy Efficiency in Buildings, asked the audience to think not in terms of 'energy efficiency,' but 'conservation of energy.' The two terms are subtly different, with the latter akin to ‘sufficiency.' Both point to the need to reduce the use of resources, not just the effectiveness which we use increasing amounts of resources.

Tristan Suffys, Secretary General of Eurogypsum, said that gypsum is well suited to fit into the low-CO₂, low-resource-use sector of the future. He called for re-use of derelict buildings, re-purposing and optimising the use of space by building above existing buildings.

The Open Congress drew to a close with a speech by the incoming President of Eurogypsum (and Head of Corporate Social Responsibility at Etex) Jörg Ertle. He told Eurogypsum members that the 'doors' marked 'Green Deal,' 'Decarbonisation,' and 'Recycling' were all 'open' and that they should be making the most of the opportunities behind each. From Global Gypsum’s perspective, it seems that they have burst through each of the doors into the rooms behind. Some are even measuring up for wallboard.

In conclusion, it appears that the European wallboard sector is at the start of a major increase in sustainability efforts. This will be backed by politicians who are keen to decouple their economies from Russia’s and a public that is increasingly asking for change. And, with three major global producers - Knauf, Saint-Gobain and Etex - based in Europe, between them sharing 47% of the world’s wallboard capacity, we can expect to see these innovations spread to other regions rapidly.

Here’s to the next 60 years!
