Still Technical Deficits
According to the current state of the art in waste paper processing, it is not possible to implement targeted countermeasures in real time to stabilize the stock-water cycles and optimize the use of chemical additives, the energy input, and production. An ideal barrier would require complete filming or adequate impermeability for product protection, but also recyclability with criteria such as sortability, removability, microbial stability, surface charge, thermal behavior, and hydrophobicity. However, these requirements cannot currently be implemented. According to the study, the selection of materials, the polymer mixture and stability against swelling, abrasion, water solubility, and mechanical fraying are important when using a barrier.
Minimum Standard Still Lacking
However, certainty regarding the sustainability of product development is limited for packaging manufacturers until the criteria for recyclability are harmonized. According to the analysis, the necessary expansion of the requirements in the minimum standard and in European legislation will only be implemented in future industrial standards. According to Krolle's estimates, the version of the test procedure for recyclability (CEPI method) updated by the European Confederation of the Paper Industry (CEPI) in October 2022 is to be integrated into the minimum standard in Germany this year. However, there is not yet a precise timetable, including for the launch of a Europe-wide method.
Important Role of Consumers
The study offers insights for the design for recycling and the recycling cycle of fiber-based packaging, explains Guido Adomßent, COO of the Veolia Umweltservice Group. This would make it easier for packaging manufacturers to differentiate between the various materials. In addition to changes and innovations in sorting and recycling technologies Consumers continue to play the main role. It is up to them to separate the waste materials and dispose of them in the appropriate containers. This is the only way to get the packaging into the appropriate waste streams.
