Abstract
The artisan production of canned tuna is characterized by generating effluents with high organic and saline loads, which complicates their suitable treatment. The main objective of the LIFE VERTALIM project is to demonstrate the efficiency of a holistic solution (including technical, legislative, social, and environmental aspects) for the controlled integration of food industry wastewater from small and medium enterprises (SMEs) in the urban sanitation system with the compliance of all stakeholders. This work shows the viability of the implementation of low-cost innovative solutions, through the clean and eco-efficient production and wastewater pretreatment for fish canneries. This solution allows on average a reduction of 30% of the wastewater discharges to the environment and a reduction of food losses of up to 0.1%. Moreover, there is a reduction of between 40% and 90% related to high organic load. These results allow the canneries to dispose their pretreated effluents to the urban sanitation system, avoiding the high costs of an industrial wastewater treatment plant (WWTP) to discharge to the river. A better physical-chemical quality in the river waters as a well as the marine water surrounding the urban WWTP have been achieved.
Highlights
The Water Framework Directive (WFD) [1] and other directives related to water have helped to strengthen the protection of the waters of the European Union (EU)
The present work shows the methodology for the implementation of a comprehensive management system for industrial and urban wastewater
The application of eco-efficient measures in the processes of food small and medium enterprises (SMEs) for the water and wastewater optimization will allow to reduce the wastewater discharges to the environment by 30% on average and the reduction of food waste of up to 0.1%

The Water Framework Directive (WFD) [1] and other directives related to water have helped to strengthen the protection of the waters of the European Union (EU). Among the aspects that affect the water quality are the industrial sectors in which there is an. Among the aspects that affect the water quality arehigh the water industrial sectors in which there is an important environmental impact caused mainly by the consumption, the generation of important environmental impact caused mainly by the high water consumption, the generation of wastewater, and the production of waste. Within this framework, we must highlight the artisanal fish wastewater, and the production of waste
