In the ecological comparison of systems, paper and cardboard products made of waste paper perform better than paper products made of primary fibres that use wood as raw material for fibres in the aspects of resource consumption, waste water pollution, water and energy consumption while the performance characteristics are similar.

The guide itself contains the main information and recommendations which are relevant for the public procurement bodies for including environmental aspects in the tender and contractual documents. The tenderer questionnaire on the green procurement of products made of recycled cardboard, which is provided in the annex, is intended as annex to the specifications.

The guide is based on the criteria of the Blue Angel environmental label for recycled cardboard (RAL-UZ 56) version of July 2014.
