MARE researchers explore the potential of algae biorefineries for a Circular Economy!

Algae are increasingly becoming an incredible source of opportunities in the field of biotechnology. With their distinct properties and bioactivities, these aquatic organisms offer a diverse range of applications, from the production of natural ingredients for cosmetics and food to the creation of value-added materials for agriculture. 

The study recently published in the prestigious Journal of Cleaner Production, led by a team from MARE Politécnico de Leiria, which includes researchers Alice Martins, Joana Silva, Celso Alves, Susete Pintéus, Carina Félix, Ana Augusto, Rui Pedrosa and Marco Lemos, delves into sustainability and develops a biorefinery that uses the enormous potential of the marine macroalga Codium sp. to generate new compounds and biomaterials with added value.

This green algae has proved to be a valuable raw material for obtaining natural ingredients with antioxidant, photoprotective, anti-enzymatic and anti-inflammatory properties that can benefit the cosmetics, food and pharmaceutical sectors.

In addition, through the application of innovative carbonization processes, in collaboration with FCUL researchers Ana Mestre, Ana P. Carvalho and Rita Santos, the leftover biomass can be converted into bio-carbonates that can improve soil health and water retention, as well as having other high-value applications, reducing waste while enhancing this resource for industry.

By using algae as a sustainable resource, these biorefineries are aligned with the principles of the circular economy, minimizing environmental impact, reducing the accumulation of waste and promoting a more environmentally friendly and economically viable approach to the use of resources, thus supporting the transition to a circular economy.
