Periodic Reporting for period 3 - SUSAAN (SUStainable Antimicrobial and Antiviral Nanocoating)
Periodo di rendicontazione: 2024-12-01 al 2025-11-30
Even after the pandemic, the situation is critic when referring to infectious diseases. More than 20% of the global annual deaths are caused by infectious diseases and up to a third of those are caused by virus infections. Apart from that, food contamination poses a challenge to be solved in the European union. There were 5146 reported foodborne outbreaks in 2018 from the EU Member States resulting in illnesses to 48,365 people. A vital agent in the process of disease transmission are the high traffic surfaces also known as fomites. Examples of these are, toilets in theatres, schools, restaurants, bars, shopping centres and sports facilities. 80% of infectious diseases are transmitted by unclean hands touching contaminated surfaces. There are existing strategies to mitigate the effect of these so-called fomites. One of them is the development of self-decontaminating surfaces. The methodology used consists on applying antimicrobial coatings to the surfaces to be treated. The issue with the actual treatments is that they are not durable enough for the destined task and they cause environmental hazards, due to their formulations.
In this sense, SUSAAN project poses a solution to help reducing the infection cases of the viruses. The project focuses on the development of new, sustainable antiviral (AV) and antimicrobial (AM) coatings with high durability for textiles and high traffic objects made of plastic and metal. SUSAAN addresses the main aspects related to high performance surface coatings. With the combined forces of key-players in the current value chain of coatings, textiles and high traffic surfaces, SUSAAN covers a set of ambitious targets focused on: a) Effective inorganic and bio-based Active Nano Materials, b) Scalable, high-performance and sustainable formulations, c) Antiviral and antimicrobial non-porous high traffic surfaces, d) Antiviral antimicrobial textiles.
These objectives have been developed considering three main pillars addressing all those aspects related to (1) Scalable manufacturing technologies and easy to repair solutions, (2) Safer-by-design materials avoiding environmental concerns and impact and (3) Standardisation aspects for effective European deployment of marketable and usable technologies.
The following specific objectives are set:
• Objective 1: Developing a range of improved Active Nano Materials (ANMs) safely tailored to the applications.
• Objective 2: Increasing fast performance and durability of the AM/AV coatings in high traffic non-porous surfaces.
• Objective 3: Increasing sustainability and stability of the AM/AV coatings in textiles.
• Objective 4: Validating the scalability of the products and the pathways for commercialization.
At the end of the project successful production of coated prototypes has been done and validation according the end-user standards has been completed. Metal samples have been tested by ECZACIBASI and optimisation were required in a first step, after that new batches of samples were prepared for evaluation and final prototypes were tests by the final user as planned in the DoA. Plastic prototypes were also finally validated by end users ECZACIBASI and PANASONIC, as well as textile prototypes by ALMAXTEX. Sustainability indicators were quantified and conclusion on BPR requirement pathway completed.
At month 42, in the third Periodic Report, main results achieved on SUSAAN project are related with the last Milestone of the project:
Successful production of coated prototypes validated according to end-users standards sustainability indicators and conclusion on BPR requirement pathway for next steps on registering. By the submission of Deliverables D4.2 D4.3 D4.4 including demonstrators, validation results according to end-user standards and final SPIs, the success of the partners was verified. In addition, deliverable D5.3 including the final regulatory assessment of the selected biocidal products including conclusion on BPR requirements for product registering. This will be supported by information on toxicity, ecotoxicity and impact assessment of D5.2 and D5.4.
Final products were applied and validated by end users ALMAXTEX, PANASONIC and ECZACIBASI.
