This review reframes marine microalgae as circular biofactories and advances a system-centric paradigm for integrated biorefineries. We synthesise recent advances in metabolic and genetic engineering, low-energy harvesting, and thermochemical and biochemical conversion, highlighting how cross-stage interdependencies dominate overall performance. We further discuss how artificial intelligence, digital twins, nutrient recycling, carbon utilisation, and high-value coproducts enable predictive optimisation and techno-economic viability. This perspective provides a road map for translating marine microalgal biofuels from laboratory promise to industrial relevance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Highlights Abstract Marine microalgae are frequently promoted as sustainable biofuel feedstocks because of their halotolerance, high photosynthetic efficiency, and limited land requirements, yet commercial deployment remains elusive.
