Third Training School

PurpleFood: PPB in sustainable nutritional and functional foods

14-16 May 2025

Antwerp – Belgium

The funding application has now closed, but registration remains open until April 15.

COST Action

COST Action CA21146

COST Action CA21146 is a four-year networking action that aims at creating a European network to share information, facilitating technology and knowledge transfer between the academic and industrial sectors, related to Purple Photosynthetic Bacteria (PPB) applications for resource recovery from organic waste sources. Resource recovery includes wastewater or organic waste, open or closed environments, in single or chain processes.

The network associates fundamental-focused and applied research groups, improving lab-scale technology optimization through mechanistic modeling. It benefits the technology transfer from applied-research groups to industry, considerably improving process design. PURPLEGAIN also aims to create a database for techno-economic, social and environmental impacts studies, which facilitates the marketability of both the PPB-based technologies and the products to extract. Some focused products are polyhydroxyalkanoates, single-cell proteins, biomass for energy, biomass as fertilizer, biohydrogen, carotenoids, terpenoids, organic acids, coenzyme Q10, and 5-aminolevulinic acid.

COST

COST is an intergovernmental framework for European Cooperation in Science and Technology established to initiate networking and coordination of nationally funded research activities on a European level. It facilitates bringing good scientists together under light strategic guidance based on networks, called COST Actions, centred around research projects in fields that are of interest to COST countries and cooperating countries.

        Evaluation process and result announcement

        Evaluation process

        The selection committee, composed of the Action Chair, the Vice Chair, the Grant Awarding coordinator, the Training Schools Coordinator and the WG2 Leader and co-Leader, will evaluate the applications within an 18-days period (after the application deadline) and will inform all the applicants for their evaluation results. The successful applicants will then receive an e-mail from the grant holder (Grant Letter Notification), stating the official approval of the reimbursement, the granted budget and a payment request form which has to be completed after the completion of the Training School.

        Criteria of reimbursement

        If the amount of reimbursement by all applications within a call does not exceed the available budget, the applications are handled by the selection committee. If there are more applications than funding is available, the following procedure takes place.

        1. A list of all applications (containing an informative summary) is distributed to all members of the selection committee in form of a table in which every evaluator can mark which applications he or she can evaluate according to their field of expertise.
        2. To guarantee a fair and objective evaluation, an evaluator should have no affiliation with neither the home nor the host institution of the application in question.
        3. All applications are evaluated by two members of the selection committee. The Grant Awarding coordinator distributes the proposals to the individual evaluators.
        4. The criteria given in the table below shall be applied for evaluation. The first criterion (a) is assessed by the Grant Awarding coordinator prior to the evaluation process.
        Criterionmax. points
