The project also received an Honourable Mention for the “Most Impactful Project Award”
The AlgaBiotec project, originated at CIIMAR, has won 3rd place in the 2025 edition of the 929 Challenge, held in Macau. The team also received an Honourable Mention for “Most Impactful Project”, standing out among international initiatives focused on innovation and sustainability. This achievement marks the third time that innovations developed at CIIMAR have been distinguished in this competition.
This year’s 929 Challenge once again brought together start-ups and university teams working on solutions that strengthen ties between China and Portuguese-speaking countries. The competition aims to encourage the development of sustainable business models that strengthen this strategic bridge, while simultaneously promoting international cooperation and entrepreneurship.
AlgaBiotec – Sustainable Technologies impressed the jury with a proposal that addresses two growing problems: the accumulation of macroalgae along the Portuguese coast and pollution from fossil-based plastics. The project focuses on transforming coastal macroalgae into minimally processed, biodegradable bioplastics. Rich in natural nutrients, the material can be returned to the soil as fertiliser at the end of its life cycle, supporting the circular economy and a more sustainable agriculture, while offering an alternative to conventional plastics. This innovative approach to natural resources’ valuation and to mitigating environmental impacts was decisive in securing the award.
Currently incubated at UPTEC, the project is now moving towards the formal creation of a start-up. The team includes Isabel Oliveira and Isabel Cunha (CIIMAR), Raquel Vaz (Iberian Nanotechnology Laboratory), and Paulo Patrício (manager).
