Biofuel from wastewater-grown microalgae: A biorefinery approach using hydrothe...

Silva, Thiago; de Aguiar do Couto, Eduardo; Assemany, Paula; Costa, Paula; Marques, Paula; Paradela, Filipe; Reis, Alberto; Calijuri, Maria Lucia

ABSTRACT: Third-generation biofuels from microalgae are becoming necessary for sustainable energy. In this context, this study explores the hydrothermal liquefaction (HTL) of microalgae biomass grown in wastewater, consisting of 30% Chlorella vulgaris, 69% Tetradesmus obliquus, and 1% cyanobacteria Limnothrix planctonica, and the subsequent upgrading of the produced bio-oil. The novelty of the work lies in inte...

Hydrothermal Co-Liquefaction of Food and Plastic Waste for Biocrude Production

Feuerbach, Silvan; Toor, Saqib Sohail; Costa, Paula; Paradela, Filipe; Marques, Paula; Castello, Daniele

ABSTRACT: In this study, hydrothermal co-liquefaction of restaurant waste for biocrude production was conducted. The feedstock was resembled using the organic fraction of restaurant waste and low-density polyethylene, polypropylene, polystyrene, and polyethylene terephthalate, four plastic types commonly present in municipal solid waste. Using design of experiment and a face-centered central composite design, t...

Admissibility Grid to Support the Decision for the Preferential Routing of Port...

Crujeira, Teresa; Trancoso, Maria Ascensão; Eusebio, Ana; Oliveira, Ana Cristina; Passarinho, Paula; Abreu, Mariana; Marques, Isabel Paula

ABSTRACT: A methodology was developed to assess the allocation of different types of endogenous waste biomass to eight technologies for producing electricity, heat, biogas and advanced biofuels. It was based on the identification of key physicochemical parameters for each conversion process and the definition of limit values for each parameter, applied to two different matrices of waste biomass. This enabled th...

Effects of Lignin Gasification Impurities on the Growth and Product Distributio...

Pacheco, Marta; Pinto, Filomena; Brunsvik, Anders; Andre, Rui N.; Marques, Paula; Mata, Ricardo; Ortigueira, Joana; Gírio, Francisco; Moura, Patrícia

ABSTRACT: This work evaluated the effects of condensable syngas impurities on the cell viability and product distribution of Butyribacterium methylotrophicum in syngas fermentation. The condensates were collected during the gasification of two technical lignins derived from wheat straw (WST) and softwood (SW) at different temperatures and in the presence or absence of catalysts. The cleanest syngas with 169 and...

The competences that humans need in a new era

Marques, Paula; Cayolla, Ricardo

The purpose of this article is to present a conceptual model of the future competences needed for human beings to be successful. Starting from the theory of constructivism, we argue that in an increasingly faster and unpredictable, more automated and digital world, human beings who improve an intrinsically human set of competences will have a better chance of future success. More than skills, these competences ...
