  • Potential of Phaeodactylum tricornutum for Biodiesel Production under Natural Conditions in Chile
    Publication . Branco-Vieira, Monique; San Martin, Sergio; Agurto, Cristian; Santos, Marco; Freitas, Marcos; Mata, Teresa; Martins, António; Caetano, Nídia
    Diatoms are very diverse and highly productive organisms, found in a wide variety ofenvironments. This study aims to analyze the growth and lipid composition ofPhaeodactylum tricornutum,cultured in an outdoor pilot-scale bubble column photobioreactor under natural conditions in Chile forbiodiesel production.Results showed thatP. tricornutumcultures reached their highest biomassconcentration (0.96±0.04 kg m−3) after 14 days of culturing, at the stationary phase, with avolumetric productivity of 0.13 kg m−3d−1. Biomass samples showed a total lipid content of9.08±0.38 wt %. The fatty acid methyl ester analysis revealed a composition of 24.39% C16-C18 fattyacids, 42.34% saturated fatty acids, 21.91% monounsaturated fatty acids and 31.41% polyunsaturatedfatty acids. These findings suggest thatP. tricornutumoil can be used as an alternative raw materialfor the production of biodiesel capable of meeting international quality standards.

  • Sustainable energy and biorefineries from biowastes
    Publication . Caetano, Nídia; Balu, Alina M.; Costa, Mário; Gouveia, Luisa; Parthiba Karthikeyan, Obulisamy; Mata, Teresa
    While renewable energy is usually considered environmentally friendly, its sustainability must be demonstrated, especially when produced from biomass sources. Moreover, there is an ongoing effort towards the development of increasing circular economy models, instead of the conventional linear economy models. This movement has opened new opportunities for the sustainable production of energy from various sources, in particular from biowaste resulting from food production and consumption, a significant source of waste that needs to be properly treated instead of disposed of. This special issue of Sustainability, with the theme Sustainable Energy and Biorefineries from Biowastes, aims to publish research or review articles dealing with the energy valorization of biowaste from various sources, mainly for producing energy or energy carriers.
