Comparing pretreatment methods for improving microalgae anaerobic digestion: Thermal, hydrothermal, microwave and ultrasound
(2015-11-01)
Article
Accés obertThe anaerobic digestion of microalgae is hindered by its complex cell wall structure and composition. Thus, several pretreatment methods have been used for increasing microalgae anaerobic biodegradability. Since the methane ... -
Cultivation and selection of cyanobacteria in a closed photobioreactor used for secondary effluent and digestate treatment
(2017-06-01)
Article
Accés obertThe main objective of this study was to select and grow wastewater-borne cyanobacteria in a closed photobioreactor (PBR) inoculated with a mixed consortium of microalgae. The 30 L PBR was fed with a mixture of urban secondary ... -
Evaluation of torrefied poplar-biomass as a low-cost sorbent for lead and terbium removal from aqueous solutions and energy co-generation
(2019-04-01)
Article
Accés obertTwo low-cost renewable poplar-based materials were manufactured in this work for energy production and as sorbents for lead and terbium removal from aqueous effluents. Torrefaction was used as a pretreatment process for ... -
Financing future-proof local bioenergy: lessons learnt from mentoring of SME pilot projects. WP5 Final report
(2018-09-04)
Report de recerca
Accés obertThe European bioenergy sector requires a wide promotion for strong investments in regional sustainable supply chain solutions. SMEs are central in the value chain in local bioenergy markets, as they are operating throughout ... -
Influence of hydrothermal pretreatment on microalgal biomass anaerobic digestion and bioenergy production
(2015-01-01)
Article
Accés obertMicroalgal biomass grown in wastewater treatment raceway ponds may be valorised producing bioenergy through anaerobic digestion. However, pretreatment techniques seem to be necessary for enhancing microalgae methane yield. ... -
Integrating microalgae tertiary treatment into activated sludge systems for energy and nutrients recovery from wastewater
(2018-01-01)
Article
Accés obertIn this study, microalgae digestate and secondary effluent were used to grow microalgae in a tertiary wastewater treatment, and then, the biomass was co-digested for biogas generation. A 30 L closed-photobioreactor was ... -
Microalgae production in wastewater treatment systems, anaerobic digestion and modelling using ADM1
(2015-07-01)
Article
Accés obertAn integrated microalgae-based system for urban wastewater treatment, microalgae production and bioenergy generation through anaerobic digestion was evaluated over a period of one year. The pilot HRAP was effective at ... -
Pretreatment of microalgae to improve biogas production : A review
(2014-11-01)
Article
Accés restringit per política de l'editorialMicroalgae have been intensively studied as a source of biomass for replacing conventional fossil fuels in the last decade. The optimization of biomass production, harvesting and downstream processing is necessary for ... -
Production of polyhydroxybutyrates and carbohydrates in a mixed cyanobacterial culture : effect of nutrients limitation and photoperiods
(Elsevier, 2018-05-25)
Article
Accés obertIn the present study, different photoperiods and nutritional conditions were applied to a mixed wastewater-borne cyanobacterial culture in order to enhance the intracellular accumulation of polyhydroxybutyrates (PHBs) and ... -
Social life cycle assessment of microalgae-based systems for wastewater treatment and resource recovery
(Elsevier, 2023-06)
Article
Accés restringit per política de l'editorialThe aim of this study was to assess the social impacts of microalgae-based systems for wastewater treatment and bioproducts recovery by using the Social Life Cycle Assessment (S-LCA) tool. In particular, two systems were ... -
The impact of poplar tree plantations for biomass production on the aquifer water budget and base flow in a Mediterranean basin
(2015-08-15)
Article
Accés obertPoplar plantations are used for biomass production in many countries. These plantations are often located in areas where the tree roots can reach the water table of shallow aquifers to reduce irrigation costs and increase ... -
Valorization of cocoa's mucilage waste to ethanol and subsequent direct catalytic conversion into ethylene
(2022-01-01)
Article
Accés obertBACKGROUND: The identification of new resources for producing biofuels and chemical-based products is crucial for processes sustainability. This study presents a valorization route to produce ethanol and ethylene using ...
