SPAIN: The technological institute AZTI leads a project that seeks to promote sustainable aquaculture and the efficient use of resources through the promotion of innovation and the transfer of knowledge in the field of the valorisation of aquaculture by-products.
The initiative, called Valacui, will be developed throughout 2018 with the collaboration of the Spanish Technological Platform of Fisheries and Aquaculture (PTEPA). The Biodiversity Foundation and the Ministry of Agriculture and Fisheries, Food and Environment, through the Pleamar Program, co-financed by the FEMP, will also collaborate.
Due to the stagnation of extractive fishing, aquaculture appears as one of the sectors of food production with greater growth capacity that will allow maintaining the proportion of fish in the global diet. However, this increase in production leads to an increase in the generation of waste. The lack of necessary infrastructures and the technical difficulties for a correct management of waste supposes a growing environmental, economic and compliance problem of the legislation on the part of the aquaculture activities.
In view of this situation, AZTI and PTEPA propose to evaluate what is the current scenario in which the by-products of aquaculture are generated, as well as what is their interaction with other similar by-products, mainly of the fishing sector.
This will be accompanied, in all the phases of the project, by contracting actions with the agents of interest that participate in the chain of the valuation of by-products of aquaculture to verify that the results are adapted to the detected needs. To this end, a panel of stakeholders of interest external to the project and belonging to the entire value chain of aquaculture will be formed, which will contribute their experience and opinion in relation to the tasks and solutions that will be developed during the project.
As a result of the project, the researchers will provide the aquaculture sector with options to value the by-products of the aquaculture value chain. Its main aspects will be included in an informative guide that allows the sector to present the existing possibilities and their variables.
In the Guide for the valuation of aquaculture by-products, the different solutions for the valorisation of the low-value fractions that can be generated in the aquaculture value chain will be collected. Likewise, the necessary information and a methodology for the pre-selection of one of these options will be included depending on the study scenario.
This document will serve, in addition to disseminating the results obtained, as a working tool: it will provide the sector with the selection criteria of the best options for valorization - technical feasibility, economic profitability, and environmental sustainability - as well as the best implementation strategy for these valuation options. A simple methodology based on multicriteria decision schemes and hierarchical process analysis will be proposed, which allows the pre-selection of valuation options based on the evaluated scenario.
Finally, and with the aim that the work carried outreach the sector, communication, and dissemination actions will be carried out, as well as workshops to transfer the results.
