Graindor Coffee

Colruyt has adapted its Graindor coffee packaging in several stages over the last few years. In 1999, it reduced the thickness of the Graindor tins by 21% from 0,28 mm to 0,22 mm, enabling 50 tons of metal to be saved a year. The weight of the plastic cover was reduced by 31%, from 9,3 grams to 6,4 grams.

The next stage was to adapt the tin’s opening system, which resulted in a reduction in material by 10 tons a year. In addition, the height of the cardboard trays that hold the tins was lowered from 7,5 cm to 5 cm (which represents a 33% reduction).

These various measures have enabled Colruyt to save 60 tons of metal, 1 ton of cardboard and 10,8 tons of plastic materials a year.
