Editorial
Marques, Rui Pedro; Vieira, Elisabete; Azevedo, Graça; Marques, SusanaIt is with great pleasure that we present the first issue of Volume 4 of the International Journal of Business Innovation. This edition continues our commitment to promoting high-quality, interdisciplinary research that reflects the dynamic challenges and opportunities in business, management, and public administration. In this issue, we feature three insightful articles that explore distinct yet interrel...
Reimagining fabrics: the role of additive manufacturing in evolving textile des...
Marques, Susana; Lopes, Carina; Miguel, Rui; Sampaio, Álvaro M.Additive Manufacturing (AM) has transformed the fashion industry over the years by allowing the production of more complex patterns, textures and geometries, enabling unprecedented levels of customization. Owing to such promising capabilities, this research focuses on evaluating the challenges and opportunities in producing different textile structures, categorised into nonwovens, wovens, and knits, through AM....
Optimizing bacterial nanocellulose production from eucalyptus bark: a circular ...
Rodrigues, Ana Cristina Costa; Martins, Daniela Sofia Rodrigues; Duarte, Maria Salomé Lira; Carvalho, Ricardo Emanuel Silva; Marques, SusanaThe production cost of bacterial nanocellulose (BNC) is a major limitation to its widespread use. However, this limitation can be addressed by using alternative low-cost substrates and high-yield strains. Agro-industrial waste-derived substrates offer a cost-effective and sustainable solution, but their high organic load often requires additional downstream wastewater treatments. Here, we optimized static BNC p...
Biopolymers Derived from Forest Biomass for the Sustainable Textile Industry
Dias, J. C.; Marques, Susana; Branco, Pedro C.; Rodrigues, Thomas; Torres, Cristiana A.V.; Freitas, Filomena; Evtuguin, Dmitry; Silva, CarlaABSTRACT: In line with environmental awareness movements and social concerns, the textile industry is prioritizing sustainability in its strategic planning, product decisions, and brand initiatives. The use of non-biodegradable materials, obtained from non-renewable sources, contributes heavily to environmental pollution throughout the textile production chain. As sustainable alternatives, considerable efforts ...

Production of sustainable aviation fuel precursors using the oleaginous yeast R...
Saraiva Lopes da Silva, Maria Teresa; Dutra, Francisca; Gomes, Miguel; Costa, Paula; Paradela, Filipe; Ferreira, Frederico CasteloABSTRACT: Sustainable aviation fuels (SAF) obtained from renewable sources of carbon can reduce carbon dioxide emissions and contribute for mitigating climate changes. In the present study, the yeast Rhodotorula toruloides PYCC 5615 was found to be highly promising for the bioconversion of eucalyptus bark hydrolysate and the accumulation of intracellular lipids which were further thermochemically processed to b...
Alternative feedstocks for high-quality biodiesel: Lipid production from eucaly...
Dias, Bruna; Lopes, Marlene; Marques, Susana; Gírio, Francisco; Belo, IsabelABSTRACT: Microbial lipids produced by yeasts from lignocellulosic biomass are a promising feedstock for the biodiesel industry, providing a renewable energy source as an alternative to traditional fossil fuels. This study investigated the potential of Yarrowia lipolytica W29 to produce lipid-rich biomass from undetoxified sugar-concentrated eucalyptus bark hydrolysate (EBH). The lipid concentrations achieved i...

Antigone with a Cape Verdean voice in the poetry of Vera Duarte
Marques, SusanaThe universal and versatile nature of Greco-Latin myths is shown by their constant revisitations by various contemporary authors. This heritage, so often reinterpreted, is capable of ‘telling’ of present realities, in permanent, ongoing dialogue across eras, spaces, sensibilities, and purposes. This is the case among several Portuguese-speaking African writers, who often evoke figures such as Antigone to articu...
Sustainability Assessment of 2G Bioethanol Production from Residual Lignocellul...
Correia, Bárbara; Matos, Henrique A.; Lopes, Tiago; Marques, Susana; Gírio, FranciscoABSTRACT: The development of sustainable biofuels can help to reduce the reliance on fossil fuels and mitigate the impact of climate change. This study analyzes bioethanol production from agro-forestry residual biomass, namely eucalyptus residues and corn stover. The study includes process simulation using Aspen Plus software, followed by economic analysis and life cycle assessment (LCA) with the help of SimaPr...
