Selected alternatives will then be tested on lab-scale against functionality criteria mainly based on physicochemical properties. If the initial functional evaluation as well as the health and environmental screening assessment and the legal status of the alternative are satisfying, the performance of the alternative solution will be further evaluated in prototype or pilot scale according to industrial standards. To achieve a proper evaluation of the alternatives, updated or improved test methods that reflect the required functional performance in real life might be implemented. For some of the industrial cases (e.g. textile/leather and to some extent paper), several different material layers or consecutive chemical treatments may be required for full performance, and thus, the compatibility between PFAS free formulations and other material treatments will be crucial. Such studies can include for instance dispersing properties on surfaces or chemical mixing properties within a chemical formulation. Final environmental and health assessment will be performed alongside technical performance to create detailed decision support for the participating industry sectors.
The POPFREE project workflow starts in a common position agreement, based in current research and industry knowledge. This is followed by mapping and selection of existing and emerging alternatives related to function. Adapting and optimizing the alternatives to match identified function criteria constitutes important parts. Also investigating and developing lab test methodologies for performance will take place. Finally environmental and health performance will be evaluated for fluorinated and predominantly for non-fluorinated alternatives.
The wide spread in branches enables cross sector innovation.
Project set up
Case studies in different sectors will support relevant alternatives to be evaluated in the different WPs, which are in the order of a substitution step by step approach.
