The REDYSIGN project, a collaborative initiative aimed at developing circular, fibre-based packaging (FBP) for fresh meat, has achieved a significant milestone to improve traceability in the sector.<\/p>\n
The project\u2019s second key phase focuses on integrating identification markers and digital sorting technologies to enhance the sorting of biocontaminated fresh meat packaging.<\/p>\n
The integration of specific identification markers into each component of fresh meat packaging is one of the core technologies of the REDYSIGN project.<\/p>\n
The markers include the tray, absorbent pad, and lidding film, facilitating accurate sorting and optimising sanitation treatments.<\/p>\n
Over the project\u2019s first 18 months, partners F\u00e1brica Nacional de la Moneda y Timbre-Real Casa de la Moneda (FNMT), Tecnalia, and PACKBENEFIT developed detection systems for both these traceability markers and pollutants.<\/p>\n
They have employed advanced sensors and imaging technologies such as RAMAN, NIR, and RGB to identify organic contaminants in absorbent pads and integrate specific markers.<\/p>\n
A notable achievement is the RAMAN marker developed by FNMT and its successful incorporation into trays thermoformed by PACKBENEFIT.<\/p>\n
Tecnalia\u2019s tests in both static and dynamic conditions have demonstrated the marker\u2019s detection efficiency, validating its potential for effective FBP sorting and recycling.<\/p>\n
The project has utilised RAMAN spectroscopy to provide chemical and structural information about the packaging materials while near-infrared technology has been used to evaluate organic components.<\/p>\n
The combination of machine vision and spectroscopy has led to the creation of AI models that can visually delineate contaminated surfaces and correlate visual data with chemical composition.<\/p>\n
Tecnalia\u2019s research has shown the effectiveness of spectroscopic sensors in detecting contaminants on food tray pads.<\/p>\n
The project\u2019s next steps will involve adjusting the maximum movement speed at which the sample moves along the surface, further enhancing the technology\u2019s industrial applicability.<\/p>\n
