Projects for Business Competitive Reinforcement Initiatives in Nuclear Transition Zones (IRC) promoted by ACCIÓ
The R-CIRCULA: Reversible Marking for the Circularity of Glass Packaging project aims to address one of the main technical barriers limiting the reuse of glass bottles in the wine sector: the use of permanent marking systems (mainly laser marking or indelible inks) to ensure product traceability.
These systems, while efficient in linear production models, are incompatible with circular economy models, as the marking cannot be removed during industrial washing processes and becomes obsolete with each new reuse cycle of the container. This limitation hinders the scalability of reuse systems and represents a barrier to their implementation at an industrial scale.
R-CIRCULA proposes the development and validation of a temporary or reversible marking system that allows the required traceability to be maintained during the bottle’s use, while enabling safe and efficient removal during the washing process, without affecting glass quality or food safety. The project adopts a collaborative approach, integrating companies from across the entire value chain and aiming to generate a model that can be replicated in other sectors.
To develop and validate a reversible marking system for reusable glass bottles that guarantees product traceability and is compatible with multiple reuse cycles, contributing to the effective implementation of circular economy models in the wine sector.
To analyse the technical, operational and regulatory limitations of current permanent marking systems.
To identify and assess alternative temporary or dynamic marking technologies (removable inks, temporary labels, digital codes, reusable RFID).
To select the most suitable solutions according to the technical, legal and operational requirements of producers and packaging managers.
To test and validate the selected solutions in real bottle reuse environments.
To assess the impact of the new system across the packaging value chain, including technical, legal and logistical aspects.
To define a scalable and replicable model applicable to other sectors using reusable packaging.
To achieve these objectives, the project will be implemented through the following main activities:
Analysis of the technical challenge posed by current marking systems, including a review of existing coding, washing and reuse processes.
Research and identification of alternative temporary marking technologies compatible with the reuse of glass bottles.
Definition of technical, regulatory and operational criteria for selecting the most viable solutions.
Development of pilot tests with the selected technologies under real industrial operating conditions.
Validation of the marking system in collaboration with the participating companies (manufacturers, reuse platforms and end users).
Evaluation of the results obtained and development of technical recommendations.
Definition of a reusable marking model that is replicable at industrial scale and transferable to other sectors.
Dissemination of results and knowledge transfer to the sector through communication and outreach actions.
