Circular Economy in the canning industry: collecting and reusing waste to give it a second life

The CONSERVAL project proposes a circular economy model for the canning industry of Galicia and Northern Portugal. On November 18, 2020, the Portuguese National Association of Canned Fish Industries (ANICP), member of the consortium, organised an online workshop in which the project milestones were presented, as well as other initiatives that also link innovation and circular economy in the fishing and canning sector.

Approximately 50 people participated in the workshop, who were able to listen to the interventions of the different members of the project, as well as other invited projects.

You can watch all the workshop sessions here and on the YouTube channel of the CONSERVAL project.

1. Álvaro Silva, from CETAQUA Galicia, started the presentation of the project’s results, relating the most important features of the canning sector in the Galicia-Northern Portugal Euroregion, the objectives and the expected results of the project, among others.

2. Leticia Regueiro, from ANFACO CECOPESCA, presented the results of the analysis and impact of the canning sector in Galicia and Northern Portugal.

3. Tamara Casero, from CETAQUA, presented a feasibility study of the production of volatile fatty acids (VFA) by means of a fermentative process using wastewater from the canning industry as a substrate. This study is part of the second activity of the CONSERVAL project focused on the development of a technology for the production of VFAs.

4. Miguel Mauricio, researcher from the Biogroup of the University of Santiago de Compostela, presented the most relevant data regarding the development and validation of a mathematical model for the prediction of fermentation effluents from the canning industry.

5. Ana Mafalda Ribeiro from the College of Engineering of the University of Porto (FEUP) explained the process applied in activity 2 of the project for the production of volatile fatty acids (VFA) from wastewater from the canning industry.

6. Leticia Reguiero from ANFACO CECOPESCA, explained the interest and usefulness of managing solid by-products and protein hydrolysates, as well as the processes they have applied in the project to obtain oils and proteins from the canning industry’s by-products and wastewater.

7. Ana Mafalda Ribeiro (FEUP) talked about the process for obtaining oils and proteins from by-products and wastewater from the canning industries that has been carried out in the project by Portuguese counterparts.

8. António J. Baptista, from the Institute of Science and Innovation in Mechanical Engineering and Industrial Engineering (INEGI), presented key tools for evaluating efficiency and sustainability in the circular economy, as well as the Co-Cereal Value project, which focuses on the recovery of by-products for cereal processing and storage

9.  Prof. Gumersindo Feijoo from the CRETUS Group of the University of Santiago de Compostela (USC) presented the NEPTUNUS project, focused on exploring the opportunities for the transition to a circular economy for the fisheries sector in the Atlantic Area.
