Insulation industry news from Global Insulation

Italy: Saint-Gobain has entered into a 10-year power purchase agreement (PPA) with Switzerland-based utilities provider Axpo Holding. Under the agreement, Axpo Holding will supply 22GWh/yr of renewable electricity from a newly built wind farm in Puglia. The deal will fulfil 11% of Saint-Gobain's Italian energy needs across 10 sites.

The latest PPA with Axpo Italia is Saint-Gobain's fifth in Italy. Collectively, these will bring the group’s reliance on renewables in its Italian operations to 20%.

Finland: Metso has launched the Outotec Mineral Wool Furnace, an electric furnace for mineral wool production. The new model is based on Metso's established proprietary equipment, used in ferroalloy and slag cleaning applications. As part of Metso's Planet Positive offering, the furnace offers reduced CO₂ emissions, high plant availability, extended life and an easily customisable modular design for specific applications.

Technology director Tom Ronnberg said “Demand for insulation materials is growing due to tightening energy efficiency requirements. At the same time, the insulation material industry is aiming for better efficiency and carbon neutrality in their production processes.”

Belgium: Knauf Insulation has released its ‘Sustainability Journey: 2023 Highlights’ report. It reveals the company’s sustainability strategy achievements focusing on safety, employee engagement, decarbonisation and the circular economy.

The company reduced its absolute full-scope emissions for its mineral wool production by 8.2% year-on-year to 1.34Mt of CO₂e in 2022 from 1.46Mt in 2021, mainly due to a significant fall in Scope 2 emissions. it currently has a target to reduce its specific embodied carbon emissions by 15% from 2021 to 2025. The recycled content of its glass mineral wool products fell to 55% in 2022 from 64%, despite the company having a target of 65% by 2025. It explained that sourcing large volumes of recycled materials of sufficient quality had proved challenging in some markets. However, it did increase the recycled content of its rock mineral wool products to 13% from 11%, with a target of 25% set for 2024. It also reduced its total recordable incident rate by 8% to 5.9 from 6.4 against a target of below 5 for 2025.

Dominique Bossan, the chief executive officer for Europe, Middle East and Asia at Knauf Group, said “The report documents our progress towards achieving our 2025 sustainability targets. It shows the areas where we need to improve, celebrates where we have made positive progress and pays tribute to the hard work of our teams."

North America: Kingspan Insulated Panels North America has launched its online Sustainability Resource Center. The platform offers educational content pertaining to sustainable construction practices by topic, type or role. It can be accessed via Kingspan's Planet Passionate portal.

Director of Sustainability Brent Trenga said "Kingspan's Sustainability Resource Center is a one-stop shop where industry professionals can expand their knowledge on the environmental impacts from the built environment. This is a resource that can be bookmarked and referenced at any given time. We want to make it easy for architects, contractors and building owners to arm themselves with information that will help them make sustainable choices in building material."

North America: Saint-Gobain has signed a 100MW solar power purchase agreement (PPA), called Danish Fields, with TotalEnergies. The Danish Fields PPA will supply Saint-Gobain North America with solar energy for 15 years, commencing in 2024. Saint-Gobain says that it expects the PPA to eliminate 90,000t/yr of CO₂ emissions across its operations. This is the group’s third deal of its kind.

Saint-Gobain North America CEO Mark Rayfield said “With this agreement, Saint-Gobain North America will further reduce its CO₂ emissions, demonstrating how fast the manufacturing industry can transform when long term solutions are at hand. This renewable energy project is a new milestone on the way to meeting Saint-Gobain’s commitment to reduce Scope 1 and 2 CO₂ emissions by 33% by 2030 compared to 2017, and to reach carbon neutrality by 2050.”

Europe: US-based Owens Corning has joined the European Alliance to Save Energy (EU-ASE). The producer said that its membership in the alliance will help in its drive for best practices in material innovation and energy efficiency in Europe.

Owens Corning’s Europe regional regulatory and sustainability senior counsel said “Owens Corning is honoured to join the EU-ASE. This is an exciting opportunity to strengthen our partnerships with key stakeholders and continue to build a sustainable future through material innovation. We are committed to the European Green Deal objectives and will continue to share best practices and knowledge across industries on key sustainability topics, such as energy efficiency, sustainability and digitalisation, while contributing to the green transition in Europe.”

Germany: Grenzebach says that it has completed the construction of the Hütten wood fibre insulation plant in Bavaria's Neustadt an der Waldnaab District for Ziegler Group subsidiary Naturheld. The plant took a total of 12 months to build, and will run on 100% renewable energy. Naturheld will use waste wood from Ziegler Group's wood processing operations in the region. Grenzebach says that it developed a novel wood blending system for implementation at the plant. The supplier said that the plant has a wood fibre production capacity of 6t/hr, and is capable of expanding to 10t/hr. The plant gives Ziegler Group the capacity to produce 1.5Mm²/yr of its wood fibre insulation product.

Managing director Stefan Ziegler said "Building the wood fiber insulation board plant within such an extremely short period was possible only thanks to the close cooperation with a renowned automation partner of international standing like Grenzebach. As a solution provider, Grenzebach supplied both the necessary product and technical know-how and expertise and was able to make the required capacities available at all times."

US: Owens Corning has published its 2022 Sustainability Report, detailing its progress towards its 2030 sustainability goals during 2022. During the year, the insulation producer reduced its CO₂ emissions by 22% compared with 2018 levels, against a 2030 reduction target of 50%. It sourced 56% of its electricity renewably. It achieved this with the help of multiple power purchase agreements (PPA), including for on-site generation. It concluded a new 81.9MW virtual PPA in Spain, which will come online in stages throughout the rest of 2023 and 2024.

Senior vice president and chief sustainability officer David Rabuano said "In 2023 and beyond, sustainability will remain at the heart of our business and a critical value creator for Owens Corning, our customers and other stakeholders. As we shift into the next chapter of our sustainability strategy, we will build on the foundational efforts that have been central to sustainability within our organisation - and with the engagement of our 19,000 employees worldwide, we will take the action needed to reach the next level."

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%.

US: Hempitecture has inaugurated a hemp-based insulation plant in Jerome County, Idaho. The plant employs five people and produces insulation using hemp grown in Montana. The producer hopes to supply its flagship HempWool thermal insulation and other acoustic and continuous insulation products to major green building materials markets, including Denver, Los Angeles and San Francisco. It began developing hemp-based insulation in partnership with the University of Idaho with a US$207,000 grant from the Idaho state government in 2021.

Hempitecture CEO Mattie Mead said "We are ushering in the future of truly sustainable building materials."
