Development of a georeferenced database as a tool to improve circular material ...
Silva, Tiago; Eusebio, Ana; Camocho, David; Alexandre, Jorge; Sousa Rocha, Cristina; Patinha, Pedro; Quental, Lídia; Gírio, Francisco; Moura, PatríciaABSTRACT: The Frontsh1p project aims to accelerate the development and implementation of cross-sector circular value chains through the creation of a multi-level toolkit that includes georeferenced data. This will facilitate the identification of the different stakeholders, their levels of interaction, regional distribution, and communication pathways, as well as the planning of new circular material flows for ...
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...
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....
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 ...
Development of the operational model and methodology of collecting data, updati...
Kochanska, Ewa; Adamkiewicz, Iwona; Wozniak, Katarzyna; Przygodzki, Zbigniew; Trippner-Hrabi, Justyna; Feltynowski, Marcin; Szafranska, EwaABSTRACT: The overall objective of the FRONTSH1P project is to ensure the green and just transition of the Polish Lodzkie Region towards decarbonization and territorial regeneration through demonstration at TRL7 of four Circular Systemic Solutions (CSS), interconnected one each other and facing the identified regional challenges/opportunities. FRONTSH1P systemic approach will be enabled by a circular governance...
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...
