D7.15 Deliverable name: Third business plans for the business cases – the four products

Summary

According to the World Health Organization, Antimicrobial resistance (AMR) is a growing threat to global health, and for the attainment of the Sustainable Development Goals (SDGs). As a result of infection with drug-resistant bacteria an estimated 700 000 people die each year worldwide. PROTECT project target is to contribute to the eliminate or at least reduce this serous health threat by developing four different antimicrobial products thank to a innovative an unique coating, realized with three different process: Water Membranes, Urinary Catheters, Hospital Linen and public area upholstery. In this third Business plan challenges, specific market, competitor for the 4 products have been deeply investigated, while financial plan and business model have been updated according to the project development, which allowed to an estimation of cost of the spray coating process, as well as more detailed and optimized estimation for R2R and batch processes.

 

D2.6 Final report on the synthesised in gram scale and characterised nanoparticles (NPs)

Summary

This reports summarizes the process for production in a gram scale of novel antibacterial and antibiofilm nanoparticles (NPs) to be further implemented in the pilot machines developed within the frame of Protect project. A platform of inorganic (Zn0.11Cu0.89O, SiO2@TiO2 composites), conjugated polymers (polypyrroles) and biological NPs has been formulated in a large scale using green and cost efficient ultrasound and sol-gel techniques. Copper oxide doped zinc NPs (Zn0.11Cu0.89O)   with high bactericidal efficacy against multiple bacterial species were prepared in a one-step ultrasound process by varying the concentration of the precursors, temperature, time of the reaction, and sonication amplitude. NPs yield of 76% was achieved using 0.2 M concentration of the precursors keeping all the physical properties of the nano-material as in a lab-scale production. Core-shell structured silica-titania nanocomposite (SiO2@TiO2) has been prepared at a large scale via the cost-efficient sol-gel route to enable a photo-active system with antimicrobial properties. The process for production in a gram scale of stable antibacterial polypyrrole (PPy) NPs dispersion was optimized using different concentrations, temperature, reaction time, and dispersing agents. Stable and concentrated suspensionsof hybrid NPs of antibiofilm enzymes and metal oxides or antibiotics were generated  via ultrasound to efficiently eliminate bacteria, at lower NPs concentrations, without affecting the viability of human cells.

 

D4.1 Report on the hazard determinants for the environment safety profile of the new processes and end products 

Summary

This report is mainly related to the establishment of the most representative exposure scenarios and the potential hazards coming from the nanoparticles (NPs) potentially released into the environment during the production and use of the developed materials. The exposure to NPs eventually released by antibacterial coated textiles and water membranes is estimated to occur mainly via inhalation in workers, while for the end-users of textiles the main exposure route is represented by skin contact. Especially in indoor environments, human exposure to the antibacterial NPs may also occur through inhalation after textile abrasion and wearing. Regarding the water depuration membranes, NPs (or other toxic by-products) may be released after leaching, finally impacting on freshwater living organisms. The methods to characterize the NPs environmental release have been set up, mainly following the OECD documents, reporting the test guidelines to measure NPs in workplaces and in the aquatic environment respectively. The bio-assays to screen the toxicity and the hazard determinants for the several new nanomaterials (NMs)proposed as efficient nano-antibacterials have been also set up. The NMs under scrutiny are sonochemically synthesized metal oxides, hybrids, polymers and colloidal solutions of polymers-metal. Such NMs represent almost completely new formulations and no data are available on their toxicity. For these reasons, different toxicity assays representative of the different exposure scenario has been performed, starting with standard in vitro tests on human lung cell lines, and 3D biological models, like human reconstructed epidermis, to go on with freshwater organisms (e.g. zebrafish embryos).

By the described methods, main determinants that may contribute to the hazard of antibacterial coating materials and technologies toward human and environmental organisms were defined.

 

D3.3 Report on the smart metabolic sensing for functional life time monitoring of the end products

Summary

This report details the progress in the development of the smart metabolic sensing molecules and their integration in the textiles employed in the PROTECT project. The report is divided into three main section: (i) selection of the sensing probe, (ii) methodologies for implementation in the textiles and (iii) evaluation of smart textile function, i.e. antibacterial capacity and bacterial sensing. In the first selection, electrochromic molecules were chosen for changing color in contact with living bacteria. A number of electrochromic molecules have been tested in solution to evaluate their metabolic sensing capacity and chromatic change. Those presenting most intense colour change in the presence of living bacteria where selected for implementation, i.e. Presto Blue and Prussian Blue. In the implementation in the textile, two strategies have been studied, concretely sonication and cyanotyping, this second only in the case of Prussian Blue. Cotton and cotton-polyester  with and without antibacterial nanoparticles have been used. Initial validation assays demonstrated that: (i) all samples presented sensitivity to the presence of live bacteria, although required long incubation times (≥20 hours for bacterial concentrations above 106 CFU/mL) and (ii) the presence of the sensing probe did not influence in the bactericidal capacity of the textiles also incorporating antibacterial nanoparticles.

D6.1 Report on the LCC and LCA of the three coating processes and recommendation for improvements based on inputs from the existing pilots

Summary

The deliverable 6.1 is the report accounting for the work done in the first eighteen months of the PROTECT project. The task is specifically referred to the sustainability issues of the identified process technologies for the PROTECT targeted applications and products. The activities planned in Task 6.1 were primarily concentrated to set-up the sustainability assessment model and the computational framework by specifying: parameters, criteria, scope and goal of the analysis. This is the basis of the PROTECT LCA-LCC studies that are being carried out throughout the whole project development: from RTD pilots scaling-up activities with the consequential LCA, to final the scaled-up pilots assessment with attributional LCA. The first impact studies were carried out and accomplished within the framework of the consequential LCA by analyzing possible processing scale-up scenarios. This provides preliminary indications towards optimization and sustainable development of the final pilot units and processes. Specific focus was given to the roll to roll sonochemical coating and to the spray coating preliminary impact assessments related to the fabric antibacterial treatment for both medical and upholstery applications. First results indicate that the processing speed is a key factor to reduce impacts and the limitation or avoidance-of ethanol would be advisable to further enhance the process sustainability.

 

D2.3 Report on the three processes up-scaled for production of antimicrobial/anti-biofilm, and biocompatible products

Summary

This deliverable describes the progress towards the scale-up of the three processes developed in Protect: i) the continuous roll-to-roll (R2R) sonochemical coating, ii) the R2R spray coating using ultrasound nozzles, and iii) the batch sonochemical coating. Partner KLO carried out experiments on the existing R2R pilot to define and optimize the parameters required for a homogenous coating that will be further used in the new up-scaled machine. Partner CENTI optimized the spray R2R coating of cotton fabrics with photocatalytic and antimicrobial silica/titanium dioxide nanocomposites. The main parameters related with the spray deposition process were optimized following specific design-of-experiments trials, with two kinds of spray nozzles: pressurized and ultrasonic. Partners UPC and BIU optimized the batch coating processes for medical devices using metal oxide nanoparticles, combination of metaloxides and enzymes, or functional biomolecules.

 

D2.1 Report on Safety by Process Design implementation for the coating processes

Summary

One of the objectives of PROTECT is to scale up the production of antibacterial textiles, obtained from the functionalization of fibers with bactericidal nanoparticles, in three pilots: 1) roll-to-roll continuous sonochemical coating; 2) roll-to-roll continuous spray coating; and 3) batch sonochemical functionalization. For each pilot, this deliverable 1) establishes criteria for estimating hazard and exposure for each nanoparticle and for each pilot; 2) defines bands (i.e.,categories) of risk that cover the full range of values given by hazard and exposure; and 3) proposes actions that minimize the risk specific to each band. By dissecting the production of antibacterial textile in each pilot, this deliverable identifies the crucial steps that must be considered in the design of future safe manufacturing. A conclusion common to all the production methods analyzed is that manual handling of chemicals and nanoparticles and open air processes lead to the highest risks for the health of workers: automation of these steps would reduce greatly the risks.
