Isover Switzerland uses 80% recycled glass to manufacture its insulating materials. The company notes that the pressure on recycled glass resources is increasing, and that local supply chains are not sufficiently organized to guarantee efficient flows in a short circuit logic. This Lucens-based SME is therefore seeking to secure long-term supplies of high-quality local glass for its "Swiss made" insulation production.

La Fabrique Circulaire's support enabled Isover to design an alternative supply solution, based on an assessment of potential volumes and a model of their geographical distribution.

At the same time, Isover was able to accelerate the establishment of several partnerships with players in the value chain. Pilot projects have been launched, with the aim of securing supplies in Switzerland within a perimeter of up to 200km, by 2025.

By reducing the number of intermediaries and sourcing more locally, the chosen solution reduces the impact of transport and the use of raw materials.

The project has also surpassed the SME's objective of identifying local sources of recycled glass to cover 50% of its needs.
