The ratio between the recycling rate reached and the best technically achievable rate for each material, expressed as a percentage. The higher, the better.
Why this indicator
Not all sectors are equal when it comes to recycling. We have therefore weighted a company's recycling capacity against the "best in class" standards declared by its sector, based on the NAF code.
A raw rate does not say whether the room for improvement is already saturated. Comparing against the state of the art per material distinguishes a company that is already exemplary from one that could do much better.
The per-material "state of the art" table is an internal Noria production, based on publicly available sector data.
Where to find the figure
Computed from a per-material "state of the art" table, to be connected on the product side. Until then, the material data is provided by the company.
