Myral on the road to Net Zero Carbon

An ambitious commitment to meet environmental imperatives

Launched a year and a half ago, the Neutral.ITE 2025 approach aims to decarbonize Myral's manufacturing processes by focusing on circularity, agility and sobriety. This initiative allowed Myral to clearly define its objectives in reducing the carbon impact of its insulation panels and to determine the crucial steps in their production processes. With quantified ambitions, the company is committed to offering a lasting solution that meets current environmental imperatives, with the support of ADEME and France Relance 2030.

For Julien Bagnard, Director of Myral: “From the start, this action has been virtuous and sincere. »

The last few months have been marked by significant progress in the eco-design of the solution, in particular by judicious choices in terms of additional insulation. This sought-after sobriety will make it possible to adapt to various types of construction sites, thus supporting renovation needs in a logic of decarbonization.

The use of recycled materials supports decarbonization

The 70% reduction in the carbon impact of the Myral solution necessarily involves the use of as many post-consumer recycled raw materials as possible in the production process. The objective is to make exterior insulation panels from everyday waste.

Sourcing is therefore an important step in the process. Aluminum in particular represents great potential for decarbonization. Myral thus compared data from suppliers who had the capacity to offer recycled materials and carried out tests on their manufacturing line. The rate of recycled aluminum, from real waste such as used cans, can go up to 75%. This represents a saving of between 6 and 8 kg CO2 per m². Several avenues are also being explored for PVC, with 50 to 100% recycled material from the deconstruction of joinery.

The decarbonization of insulating foam, on the other hand, is a real challenge and the integration of recycled plastic bottles into the formulation is very promising. The use of around 15% recycled material in the composition would save almost 3 kg CO2 per m².

With the use of 5 to 6 bottles per m², this possibly represents the recycling of 1,5 million bottles per year.

For Julien Bagnard, Myral director, the overall message is clear: “Circularity is the cardinal value advocated by Myral”. Old aluminum cans, used plastic bottles and PVC joinery can now have a second life to insulate homes and offices and allow their occupants to save energy on a daily basis. Cleaning up nature's waste and fighting global warming by insulating buildings is the path that Myral wishes to take over a long-term approach.

A well-started approach

The challenge of the Neutral.ITE approach is to transform these good ideas into reality. Since 2023, Myral's work has mainly focused on the modifications to be made to the CSTB technical opinions, notably requiring numerous material characterization tests.

First major step: at the beginning of 2024, several FDESs for Myral eco-designed products will be published, thus certifying the reduced impact of their systems, while validating these raw materials within the framework of technical advice, ACERMI certification and laboratory assessment at the fire level.

Then, the challenge for 2025 will be the integration of other types of insulation in addition, perhaps even more low-carbon, such as wood fiber with a carbon storage component. At the same time, Myral is also committed to working on the carbon contribution via tree planting in France and agroforestry in order to achieve Net Zero Carbon on 100% of the process. This solution has the advantage of storing carbon over the long term and helping to reconnect with the creation of biodiversity.

Neutral.ITE Myral: a virtuous approach for the sector

The challenge of the Neutral.ITE approach is to transform these good ideas into reality. Since 2023, Myral's work has mainly focused on the modifications to be made to the CSTB technical opinions, notably requiring numerous material characterization tests, validated as part of the laboratory fire assessment. Next major steps in early 2024: finalization of the verification of the FDES and their publication on the inies.fr website, thus certifying the reduced impact of their systems; and validation of changes within the framework of the CSTB technical opinion and ACERMI certification.
