Insulation industry news from Global Insulation

Denmark: Saint-Gobain’s subsidiaries Isover and Leca have started an agreement with waste management company Norrecco to recycle glass wool insulation. Under the new system, contractors will be able to return used and excess Isover glass wool to Norrecco's waste treatment stations at Prøvestenen in Copenhagen and at Agerskov in Southern Jutland. Norrecco will then pass the glass wool to Leca Denmark’s plant at Hinge near Randers. Here it will be used as a raw material in the production of lightweight expanded clay aggregate (LWA) products. LWA is used in a variety of applications such as insulation or as a structural filler. Leca added that LWA can be recycled repeatedly.

Mona Ammitzbøll Rasmussen, the Sustainability Engineer at Saint-Gobain Denmark, said "From the moment our glass wool leaves the factory, we want to support the idea that the material will one day return and be used in the production of new insulation materials, rather than ending up in landfills. It is an unnecessary waste that we need to eliminate as soon as possible."

Leca Denmark has the capacity to accept around 1000t/yr of used or excess glass wool from the Danish market. The company said that, although it represents a small portion of the total production, it reduces the need to extract a corresponding amount of natural clay, which is the primary raw material in its Leca LWA product. Isover is also working on publishing guides to better help contractors sort between the different types of mineral wool to assess purity ahead of potential recycling.

Belgium: PU Europe has issued a statement to the relevant European bodies responsible for fluorinated gases (F-gases) emphasising the role of low global warming potential (GWP) of F-gases in insulation foam applications.

The association has suggested that, instead of total ban of F-gases, a lowering of the threshold should be considered as an alternative. In its view a lower threshold would allow the users of thermal insulation to continue to benefit from products made from closed-cell polyurethane foam. It warned that a ban on the use of low GWP F-gases in insulation foam would have “significant implications for the Renovation Wave, as approximately 80% of the buildings that will exist in 2050 have already been constructed.” PU Europe emphasises the need to find solutions that strike the right balance between addressing operating greenhouse gas emissions from the existing building stock and controlling low GWP F-gases.

The European Commission proposed in early 2022, as part of its so-called 'fit for 55' package, to further reduce emissions of F-gases. It wants to change the existing quota system, gradually reducing the supply of hydrofluorocarbons to the European Union market to 2.4 % of 2015 levels by 2048.

PU Europe was founded in 1981 as BING to become the single European voice for the polyurethane insulation industry. The association represents insulation producers, raw material suppliers and component manufacturers from eleven countries with activities covering the entire continent.
