Madrid, September 17, 2025 – Nauterra, a global food company specializing in canned fish and seafood, continues to advance its commitment to sustainability, closing 2024 having achieved nine of the goals set out in its ‘Reponsible Engagement’ strategy. This ambitious program, made up of 21 goals with a 2025 horizon, was launched in 2019 with the aim of reducing impacts across three areas—oceans, environment, and people—while fostering value creation for the business, society, and the environment through responsible management.
According to Mariví Sánchez, Nauterra’s director of Sustainability and Communications: “Reaching nine of the 21 goals we set back in 2019 has not been easy. Behind every step forward lies tremendous collective effort and serious work that has meant transforming processes, learning from challenges, and rethinking how we operate as a company. Beyond the targets set for 2025, this journey has allowed us to lay stronger foundations, and we are already working on new sustainability goals that we hope will take us even further.”
One of the most notable milestones of the year was waste management, within the framework of the Nauterra Zero Waste project. Specifically, the company recovered 98.86% of the non-hazardous waste generated across its factories, offices, and fleet. This represents an improvement of 1.38 percentage points compared with 2023 and reflects steady progress toward the goal of achieving full recovery (100%) by the end of 2025.
In 2024, a total of 53,282 tons of tuna and sardine by-products were reintroduced into the production cycle that otherwise would have been discarded, giving them a second life as fishmeal and oil used in animal nutrition, as fertilizers, or in the chemical and cosmetics industries. Thanks to these efforts, in 2024 the packaging and finished product plants in Spain and Brazil renewed their “Zero Waste” certification. In addition, the Group also ensured that nearly 100% of the products placed on the market are recyclable, and that almost half of the materials it uses come from recycled sources or are certified as sustainable.
Commitment to Sustainable Food and Transparency
As part of its ‘Responsible Engagement’ strategy, the company has also continued to strengthen the sustainable sourcing of raw materials. More than 92% of the tuna loins used in products under the Calvo, Nostromo, and Gomes da Costa brands come from certified responsible and sustainable sources—around 7% more than last year. This is a particularly important objective for the company, given its role as a food group specialized in canned fish and seafood.
In 2024, Nauterra also introduced a series of updates to its product labeling, aligning with the latest regulatory frameworks and reinforcing its commitment to transparent, accessible, and useful communication for consumers. In Spain, several improvement initiatives were carried out to ensure greater clarity and understanding for shoppers. Among them, the company updated its allergen declarations, making the presence of fish more visible and reformulating precautionary statements so that any potential trace content now appears in bold, making it easier to identify.
People at the Heart of Nauterra’s Business
On the social front, Nauterra was certified by Bureau Veritas as a Healthy Organization, a recognition that highlights the company’s comprehensive promotion of well-being across five key areas: psychosocial environment, physical environment, training and communication, community engagement, and health resources. This distinction adds to other social initiatives led by the company, such as inclusion and diversity actions, work-life balance and mental health measures, and professional development programs. In fact, once again this year, the company surpassed 36 hours of training per employee.
With these advances, Nauterra strengthens its commitment to a sustainable development model that integrates innovation, care for the environment, and concern for people—aligned with major global challenges and societal expectations.
