Life cycle assessment and economic analysis of bioplastics production from cyanobacteria
(Elsevier, 2023-04)
Article
Open AccessCyanobacteria are interesting microorganisms to produce polyhydroxybutyrate (PHB), a biodegradable plastic similar to polypropylene. In this study, a Life Cycle Assessment and an economic analysis were carried out to assess ... -
Nature based-solutions for water reuse: 20 years of performance evaluation of a full-scale constructed wetland system
(2023-03)
Article
Open AccessWater reuse is becoming an important tool in water resource management in regions with recurrent droughts and water shortages, such as the Mediterranean. However, there are still obstacles preventing the multiple application ... -
Recent advances and perspectives in the use of conductive materials to improve anaerobic wastewater treatment: a systematic review approached
(2022-12)
Article
Restricted access - publisher's policyIn recent years, many researches have reported that anaerobic digestion and methane production can be significantly improved with the addition of conductive materials to the process. Despite advances, a number of questions ... -
A robust multicriteria analysis for the post-treatment of digestate from low-tech digesters. Boosting the circular bioeconomy of small-scale farms in Colombia
(2022-09)
Article
Open AccessLow-tech digesters are sustainable technologies to produce a clean fuel (biogas), which can be used for cooking and heating. Moreover, the degradation of organic waste in the digester also produces a liquid effluent ... -
Selenium recovery from wastewater by the green microalgae Chlorella vulgaris and Scenedesmus sp.
(Elsevier, 2022-12)
Article
Open AccessSelenium (Se) is an important element for many living organisms and its supplementation may be needed in food, feed, and soil to make up for its deficiency. At the same time, high selenium concentrations can harm the ... -
Production of phycobiliproteins, bioplastics and lipids by the cyanobacteria Synechocystis sp. treating secondary effluent in a biorefinery approach
(Elsevier, 2023-01)
Article
Open AccessCyanobacteria have been identified as promising organisms to reuse nutrients from waste effluents and produce valuable compounds such as lipids, polyhydroxyalkanoates (PHAs), and pigments. However, almost all studies on ... -
Life cycle assessment of microalgae systems for wastewater treatment and bioproducts recovery: natural pigments, biofertilizer and biogas
(Elsevier, 2022-11)
Article
Restricted access - publisher's policyThe aim of this study was to assess the potential environmental impacts associated with microalgae systems for wastewater treatment and bioproducts recovery. In this sense, a Life Cycle Assessment was carried out evaluating ... -
Can microalgae grown in wastewater reduce the use of inorganic fertilizers?
(2022-12)
Article
Open AccessAlternatives to conventional inorganic fertilizers are needed to cope with the growing global population and contamination due to the production and use of those inorganic compounds. The recovery of nutrients from wastewater ... -
Process optimization of the polyhydroxybutyrate production in the cyanobacteria Synechocystis sp. and Synechococcus sp.
(Elsevier, 2022-07)
Article
Restricted access - publisher's policyThe effect of four parameters (acetate, NaCl, inorganic carbon and days in darkness) affecting the polyhydroxybutyrate (PHB) production were tested and optimized for Synechococcus sp. and Synechocystis sp. using a Box-Behnken ... -
Monitoring PHB production in Synechocystis sp. with hyperspectral images
(2022-07)
Article
Open AccessMicroalgae wastewater treatment systems have the potential for producing added-value products. More specifically, cyanobacteria are able to accumulate polyhydroxybutyrates (PHBs), which can be extracted and used for ... -
Power assisted MFC-based biosensor for continuous assessment of microbial activity and biomass in freshwater ecosystems
(Elsevier, 2022-08)
Article
Restricted access - publisher's policyMicrobial activity and biomass are important factors that determine nutrient and carbon fluxes in freshwater ecosystems and, therefore are also related to both water quality and climate change induced stressors. This study ... -
Machine learning methods modeling carbohydrate-enriched cyanobacteria biomass production in wastewater treatment systems
(2022-04)
Article
Open AccessOne-stage production of carbohydrate-enriched microalgae biomass in wastewater is a promising option to obtain biofuels. Understanding the interaction of water quality parameters such as nutrients, carbon, internal ...
