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 PaulaABSTRACT: 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...
Mapping municipal solid waste to boost circular valorization practices in Łódzkie
Moura, Patrícia; Eusebio, Ana; Patinha, Pedro; Quental, Lídia; Lukasik, Rafal M.ABSTRACT: Geographic Information System (GIS) is a powerful instrument that can be used for the spatial representation of waste and by-product flows at various levels, allowing to improve municipal solid waste (MSW) management. The mapping obtained can be advantageously targeted to build a regional network of technological, economic, social and environmental linkages and to boost circular economy practices. In ...
Efficient conversion of agricultural and forest residues into bioethanol: BIOFL...
Marques, Susana; Paixão, Susana M.; Alves, Luís; Gomes, Miguel; Eusebio, Ana; Lopes, Tiago; Coelho, Lucas; Diebold, Eduardo; Gírio, FranciscoABSTRACT: Lignocellulosic ethanol is in the upfront of advanced biofuels to be commercialized worldwide. However, the commercial deployment of 2G ethanol is dependent of high biomass availability and cost-effective supply. In Europe, some agricultural residues are presently underused and constitute attractive renewable resources. In addition, residual forest biomass, non-seasonably available at low cost, might ...
Anaerobic Digestion of Microalga Chlorella protothecoides and Metagenomic Analy...
Eusebio, Ana; Santos, Carla A.; Marques, Isabel PaulaABSTRACT: Microalga Chlorella protothecoides materials were assessed as substrates for anaerobic digestion (AD) aiming at the simultaneous production of biogas/methane and pigments: whole autotrophic (AA) and heterotrophic algae (H); extracted heterotrophic microalgae from lipid production (HExt); and pretreated heterotrophic microalgae through enzymatic (HPEnz), autoclave (HPA), and ultrasound (HPU) processes....
Fermentation Wastes from Chrypthecodinium cohnii Lipid Production for Energy Re...
Eusebio, Ana; Moniz, Patricia; Silva, Teresa Lopes da; Marques, Isabel PaulaABSTRACT: Wastes generated during the cultivation of marine microalga Crypthecodinium cohnii and after the lipid extraction process, were energetically valorized into biogas production through anaerobic digestion (AD). The tested wastes were extracted microalgae (Ae) with hexane (AeH) using supercritical extraction methods (AeS) and the supernatant obtained after culture medium centrifugation (M). The digestion...
Complementary substrates-brewery wastewater and piggery effluent assessment and...
Eusebio, Ana; Neves, André; Marques, Isabel PaulaABSTRACT: A hybrid anaerobic reactor was operated under the complementary effluents concept to reduce the unbalanced/inhibitory capacity of the provided piggery effluent. Brewery wastewater was chosen to complement piggery effluent (60:40% v/v, respectively). The HRT reduction from 6.7 to 3.0 days allowed the testing of an organic load increase from 4.5 to 10.0 g COD/L center dot d, which resulted in the almost...
Structure of microbial communities when complementary effluents are anaerobical...
Eusebio, Ana; Neves, André; Marques, Isabel PaulaABSTRACT: Olive oil and pig productions are important industries in Portugal that generate large volumes of wastewater with high organic load and toxicity, raising environmental concerns. The principal objective of this study is to energetically valorize these organic effluents-piggery effluent and olive mill wastewater-through the anaerobic digestion to the biogas/methane production, by means of the effluent c...
Valorização energética de resíduos do processamento de castanha por digestão an...
Loureiro, F.G.; Eusebio, Ana; Marques, Isabel PaulaCIES2020 - XVII Congresso Ibérico e XIII Congresso Ibero-americano de Energia Solar; RESUMO: Os resíduos/efluentes oriundos da indústria da castanha constituem um potencial de valorização energética por digestão anaeróbia (DA). Resíduos sólidos (cascas e frações de polpa, “RS”) e lamas resultantes do tratamento de águas residuais (“LT”), ambas provenientes do processamento de castanha, foram anaerobiamente dige...
Rhodobacter and pigments in anaerobic digestion of brewery effluent
Neves, André; Ramalho, Luís; Eusebio, Ana; Marques, Isabel PaulaABSTRACT: Brewery wastewater (BWW) was digested anaerobically in mesophilic conditions and batch mode. The presence of a reddish pigmentation associated to the better removal capacity of the BWW digestion (64%), indicates that the treatment and energetic valorisation of an organic effluent can occur at the same time and inside the same unit as the production of a photosynthetic pigment. The reddish pigmentation...
Hybrid anaerobic reactor: Brewery wastewater and piggery effluent valorisation
Neves, André; Roseiro, Luisa B.; Ramalho, Luís; Eusebio, Ana; Marques, Isabel PaulaABSTRACT: A hybrid anaerobic reactor (HAR) operated to digest brewery wastewater, complemented with piggery effluent (60% and 40% v/v, respectively), under three hydraulic retention times: HRT: 5.7, 3.0 and 1.0 d. Along the first phase, the biogas of 0.9 LL− 1d− 1 evolved to 1.2 LL− 1d− 1 with a methane content of 77–78%. The HRT reduction to 3 days promoted the production until 2.1 LL− 1d− 1, with methane prop...
