To determine the percentage of packaging material available for quality recycling, both the different packaging characteristics ( colour, materia Is, dimensions, etc.) and the currently available and applied technologies to achieve viable quality recycling are token into account. The criterio for such a determination take as a basis certain criterio of UNE EN 13430/ISO 18604, IS014021 standards, the UNE CEN/TR 13688 IN Report, as well as their own established requirements for guaranteeing that the resulting material allows quality recycling to be undertaken by testing recycling processes.

The methodology is developed by Dríade Soluciones Medioambientales and has the external review and scientific support from the UNESCO Chair of Life Cycle and Climate Change ESCI-UPF, which guarantees the scientific rigor and neutrality of the capacity of each packaging to be reincorporated into a quality production cycle. The Gremi de Recuperació de Catalunya consists of more than 300 recovery and recycling companies (member of EuRIC and BIR) examines and guarantees that the evaluations are carried out in accordance with the recycling processes currently in the market. SGS International Certification Services Ibérica, S. A. U. audits the evaluation process used by Dríade Soluciones Medioambientales and guarantees the compliance with the criteria established in the certification and labelling procedures.

*Dríade Soluciones Medioambientales is the only entity accredited to use this methodology and to grant the Certificate and authorisation for the use of the Seal of Recyclability.
