Goal 1

By 2026, we recover 80 % of our rubber waste so that it can be recycled and incorporated into our products*.  

* Rubber accounts for 75 % of the raw materials injected at BIWI. The introduction of waste recovery reduces our waste by 7 t in 2026, compared with a total of 10 t in 2020. Typical waste: unvulcanised rubber (raw material scrap), vulcanised rubber (reject parts), partially vulcanised rubber (sprues & injection channels).

Goal 2

By 2024, 80 % of the plastic products offered to customers is biosourced or recycled*.  

* Biosourced: Derived from biomass, through an eco-responsible process). Plastics account for 20 % of the raw materials injected at BIWI.

In 2021, BIWI developed biosourced or recycled technical materials that can meet watchmaking specifications and are systematically offered to customers when the technical criteria can be met.

Internal operations
