Development of new materials for marine regeneration structures from  by-products of the steel and agri-food industry

July 2022 - July 2025

Funded by
ACCIÓ (Catalonia's agency for business competitiveness, attached to the Department of Business and Employment)


The Government of Catalonia has been promoting policies to support industry and business for decades, considering them as the core of the economy and a source of wealth and employment.

Technological advancement is key to providing solutions that positively impact companies and society as a whole. In fact, technology and innovation are drivers of economic recovery and competitiveness, along with internationalization, which needs to be strengthened to address the challenges faced by Catalonia’s productive fabric.

In this context, through ACCIÓ (Catalonia’s agency for business competitiveness, attached to the Department of Business and Employment), this line of grants is promoted, aimed at subsidizing industrial research and experimental development projects led by a Catalan company, with the aim of advancing currently available technology.

Project Description

The decrease in global biodiversity in seas and oceans is mainly due to the conversion of marine habitats into hostile environments for marine flora and fauna due to increased coastal activity and maritime traffic, as well as pollution from waste discharge into the waters. The loss of marine biodiversity has serious environmental and societal implications as it affects oxygen generation, decarbonization, the balance of trophic and food webs, as well as the resilience of marine organisms to cope with climate change.

This project presents a solution focused on a sustainable and circular economy that promotes social and economic development respectful of the environment and promotes the conservation of natural resources. Specifically, the SEASLAG project proposes the research and development of a new sustainable material for the creation of marine regeneration structures that allow the growth of marine biodiversity. To achieve this, the valorization of by-products obtained in the industry will be studied with the aim of maximizing bioregeneration capacity and promoting the circular economy.

Currently, solutions developed for marine regeneration are based on the construction of artificial reefs using raw materials such as concrete, steel, or polypropylene derivatives, resulting in resilient structures suitable for marine life growth. Despite being highly efficient solutions, the construction of these structures entails the depletion of natural resources. Therefore, the main differential innovation presented by the SEASLAG project consists of the incorporation and valorization of by-products from the steel and agri-food industry for the construction of these marine structures using 3D printing techniques. In this way, not only will the number of natural raw materials used for their manufacture be reduced, but materials that currently do not have a second life and are destined for landfills with the corresponding environmental impact will be valorized.
