PRESERVE aims to improve the circularity of bio-based packaging from origin and design to subsequent life cycles. The project intends to enhance the properties of existing bio-based materials for different packaging applications using innovative processing technologies. New end-of-life options, including innovative upcycling solutions, will be applied to make sure these new packaging applications are fit for a truly bio-based, circular economy.

This deliverable describes the specifications for five pre-selected secondary raw material applications: personal care flow pack, personal care injected jar, injection-moulded bottle, packaging textile, and carrier boxes - all of which are targeted to be obtained from recovered food packaging materials.

The confidential report provides detailed information on the requirements for the materials and processing technologies, the demonstrators’ properties and expected challenges, as well as innovative upcycling solutions and end-of-life options, based on the knowledge of the manufacturers and brands that are part of the project consortium. The partners specifically focus on the processability of each of the developed materials and the tolerance to impurities for each application, resulting from the recovery step. The properties and functionalities of the materials currently used for the selected applications are used as a benchmark to make sure fossil-based materials can easily be replaced by the developed bio-based SRM solutions. The report also specifically focuses on the processability of each of the developed materials and the tolerance to impurities for each application, resulting from the recovery step.

Other specific market requirements, such as cost aspects, regulatory conformity, environmental aspects, and consumer demands are also assessed and defined.
