The suppliers had to meet special requirements when Marks & Spencer in 2007 launched their comprehensive environmental initiative.

For instance United Biscuits, supplier of snacks and biscuits, had to review their way to package in order to cut away all superfluous packaging without compromising the product quality.

For nuts they chose a metal packaging from Glud & Marstrand.

The packaging was chosen because it matches the British recycling system which reuses clean metal packaging efficiently.
