Insulation industry news from Global Insulation

Ireland: Kingspan's CO₂ emissions fell by 26% over the two years between 2020 and 2022. The group aims to achieve a 90% reduction in CO₂ emissions between 2020 and 2030. The Irish Times newspaper has reported that the company adopted a Euro70/t internal pricing mechanism in January 2023. Over the past three years, it increased its renewable energy share to 33% from 20%, increased its rainwater harvesting capacity by 26% and reduced its volume of waste sent to landfill by 42%.

Kingspan head of sustainability Bianca Wong said "It’s a testament to the enduring efforts of our colleagues that we completed over 100 projects in 2022. We will continue to build on our progress to date and aim to further accelerate our strategies in the coming years."

US: Saint-Gobain plans to invest a total of US$400m in expansions to its operations including insulation operations at four US sites. The group says that the sites are located in California and the Southeastern US. It said that the new capacities will apply the most advanced available technologies for industrial performance, safety and sustainability. This will reduce waste by 50% and CO2 emissions by 20% from current levels, according to the company.

Saint-Gobain said it hopes that the investments will strengthen its leadership in North America and accelerate its growth in the region by enriching its comprehensive range of solutions for light and sustainable construction.

Uzbekistan: The European Bank for Reconstruction and Development has issued a US$5m loan to Ecoclimat Group for the launch of a new subsidiary, Angren Insulation. The company will use the loan to build a 32,000t/yr glasswool plant in Tashkent. The plant will use recycled glass as an input and reduce the group’s CO₂ emissions by 85,000t/yr. The insulation producer said that it will help it to meet the growing local demand for mineral-based insulation.

Russia: Rockwool plans to install a new mineral wool production line at its Vyborg insulation plant in Leningrad oblast. The producer says that the expanded plant will have 50% lower CO₂ emissions than before the expansion due to an efficiency increasing upgrade to its melting technology.

Rockwool plans to invest Euro200m in expansions and efficiency improving upgrades in Russia ‘in the coming years,’ creating 70 new jobs.

US: In 2019 Owens Corning sourced 1.58GWh of energy renewably (49% of total consumption), down by 14% year-on-year from 1.84GWh (52% of consumption) in 2018. Direct CO₂ emissions were 2.78Mt, down by 2.0% from 2.83Mt in 2018 due a reduction in carbon intensity of insulation production, such as the use of electric rather than coke-fired furnaces.

UK: Global not-for-profit organisation CDP has included Owens Corning on its Climate Change A-List 2019 for environmental transparency and performance aimed at facilitating a zero-net carbon economy. Only a handful of industrial producers achieved inclusion on the list, including France-based Saint-Gobain and Germany-based HeidelbergCement and steel producer Thyssenkrupp.

China: A study by researchers from Australia's Commonwealth Scientific and Industrial Research Organisation and Britain's University of Bristol says that the provinces of Shandong and Hebei are the source of a rise in trichlorofluoromethane (CFC-11) emissions. It attributed about 40% to 60%of in the rise in CFC-11 since 2013 to this region, according to Reuters. After studying atmospheric data from South Korea and Japan they estimated that CFC-11 emissions from eastern China during the 2014 - 2017 period were around 7000t/hr higher than 2008 - 2012.

Previously in mid-2018 an investigation by the Environmental Investigation Agency (EIA) speculated that the widespread use of CFC-11 by Chinese rigid polyurethane (PU) foam producers might be the source of the reported rise of emissions.

China launched an inspection campaign into 3000 foam manufacturers in 2018 and promised to punish any violations of the Montreal Protocol treaty. The Ministry of Ecology and Environment said in March 2019 that it had shut down two manufacturing areas that produced CFC-11. It added that its investigation into PU foam makers had not found any large-scale usage so far but that producers may be getting better at hiding their operations. It also noted that there was ‘uncertainty’ in published research and called for better detection mechanisms.

US: The chief executive officers (CEO) of 13 US companies, including BASF and DuPont, are lobbying the President and Congress to enact business-led climate change legislation. This initiative, known as the CEO Climate Dialogue, urges the government to put in place a long-term federal policy as soon as possible, in accordance with a set of six guiding principles. The group aims to build bipartisan support for climate policies that it says will, “… increase regulatory and business certainty, reduce climate risk, and spur investment and innovation needed to meet science-based emissions reduction targets.”

Companies involved in the CEO Dialogue include BASF, BP, Citi, Dominion Energy, Dow, DTE Energy, DuPont, Exelon, Ford Motor Company, LafargeHolcim, PG&E, Shell, and Unilever. Four environmental groups have also supplied input to the initiative. These are the Center for Climate and Energy Solutions, Environmental Defense Fund, the Nature Conservancy and World Resources Institute.

The six principles include: ‘significantly’ reducing US greenhouse gas emissions; allowing an effective timeline for reductions that will enable capital intensive industries to adjust in an ‘economically rational manner’; instituting a market-based price on carbon; making the policies durable and responsible; doing no harm to the competitiveness of the US economy with particular attention to carbon leakage; and promoting equity. Specifically the initiative says that US policy should ensure the country is on a path to achieve economy-wide emissions reductions of 80% or more by 2050 with ‘aggressive’ short and medium term emissions reductions.

“DuPont is pleased to be part of the CEO Climate Dialogue and support its guiding principles to accelerate the development of federal policy on climate change. At DuPont, our science and innovation is inextricably linked with sustainability practices that deliver specialised materials that contribute to a safer, healthier, more sustainable world. We believe strong, consistent policy measures and a cohesive regulatory environment are needed to accelerate the transition to a low-carbon economy and foster innovation, investment and economic growth,” said Marc Doyle, CEO-Elect of DuPont.

China: An investigation by non-government agency the Environmental Investigation Agency (EIA) has found that trichlorofluoromethane (CFC-11) is being widely used as a blowing agent in the rigid polyurethane (PU) foam insulation sector. The EIA contacted 25 precursor or foam producers and found that 18 of these plants were using CFC-11 in 10 different provinces.

In May 2018 the journal Nature revealed that CFC-11 emissions had increased by around 25% since 2012 despite reported production being close to zero in 2006. CFC-11, other chlorofluorocarbons (CFCs) and substances that damage the Ozone Layer were banned under the Montreal Protocol from 2010.

The EIA speculates that widespread use of CFC-11 by Chinese PU foam producers may be the source of the reported rise of emissions. It estimates that up to 3500 small and medium sized companies could have switched to using CFC-11 following a reduction in the supply of HCFC-141b, an alternative blowing agent, and lax enforcement of the ban on CFC-11. One company representative the EIA spoke to said that HCFC-141b was US$150/t more expensive than CFC-11.

“This is an environmental crime on a massive scale. How the Montreal Protocol addresses this issue will determine whether it continues to merit its reputation as the world’s most effective environmental treaty,” said Climate Campaign Leader Clare Perry.

The EIA has released its report ahead of the Open-Ended Working Group of the Montreal Protocol meeting in Vienna in mid July 2018.

Canada: An Owens Corning fiberglass insulation plant in Edmonton has been ordered to monitor its emissions following a fire in early January 2016. The fire on 4 January 2016 damaged the plant's secondary air scrubber on its insulation batting production line.

Without the second scrubber the plant is contravening its Environmental Protection and Enhancement Act approval. A remedial solution to replace the curing oven's secondary air scrubber could take more than six months to implement.

As part of an enforcement order Owens Corning must monitor and notify Alberta Environment and Parks of any significant deviation from normal performance of the primary air emission scrubber on the curing oven. If the plant exceeds any air emission limits then production must immediately stop. Additional monitoring on the curing oven stack, including manual stack surveys, and an approved ambient air-monitoring plan are also required.
