Arsenic Retention on Technosols Prepared with Nanoparticles and Ferric Soil from Mine Drainage Water
(Hindawi, 2018)Mining activities generate a large amount of solid waste and acid drains that contain heavy metals in high concentrations. In wastewater of gold mines from Southern Ecuador (Portovelo), arsenic concentrations between 4.8 ... -
Equilibria and correlation of systems involving 1-hexyl-3-methylpyridinium trifluoromethanesulfonate
(Royal Society of Chemistry, 2019)Ionic liquids are being proposed for the improvement of many refinery-related applications where water and oil coexist. However, the lack of relevant thermodynamic data on equilibrium processes involving water, oil and an ... -
Miniaturized matrix solid-phase dispersion for the analysis of ultraviolet filters and other cosmetic ingredients in personal care products
(MDPI, 2019)A method based on micro-matrix solid-phase dispersion (μ-MSPD) followed by gas-chromatography tandem mass spectrometry (GC–MS/MS) was developed to analyze UV filters in personal care products. It is the first time that ... -
Targeted conversion of protein and glucose waste streams to volatile fatty acids by metabolic models
(Elsevier, 2019)Mixed-culture fermentations are recognised as suitable processes to valorise organic wastes and convert them into added-value products. One of the main issues of these processes is that the stoichiometry of the fermentations ... -
Trends in the Recent Evolution of Coastal Lagoons and Lakes in Galicia (NW Iberian Peninsula)
(MDPI, 2019)Coastal lagoons are habitats of great environmental value. However, they are currently subject to major threats, particularly due to increasing sea levels. This study aims to identify changes—both natural and induced by ... -
Utilization of Composts for Adsorption of Methylene Blue from Aqueous Solutions: Kinetics and Equilibrium Studies
(MDPI, 2020)Utilization of composts as low-cost adsorbents is an important application in the field of environmental remediation, but these materials have not yet been extensively used for dye removal. In this work, we have studied ... -
Environmental assessment of viticulture waste valorisation through composting as a biofertilisation strategy for cereal and fruit crops
(Elsevier, 2020)Composting is a solid waste management alternative that avoids the emission of methane associated with its disposal in landfill and reduces or eliminates the need for chemical fertilisers if compost is applied. The main ... -
Selecting for lactic acid producing and utilising bacteria in anaerobic enrichment cultures
(Wiley, 2020)Lactic acid‐producing bacteria are important in many fermentations, such as the production of biobased plastics. Insight in the competitive advantage of lactic acid bacteria over other fermentative bacteria in a mixed ... -
Towards a digital twin: a hybrid data-driven and mechanistic digital shadow to forecast the evolution of lignocellulosic fermentation
(Wiley, 2020)The high substrate variability and complexity of fermentation media derived from lignocellulosic feedstocks affect the concentration profiles and the length of the fermentations. Not accounting for such variability raises ... -
Transient and Persistent Energy Efficiency in the Wastewater Sector based on Economic Foundations
(International Association for Energy Economics (IAEE), 2020)Given the increasing importance of the wastewater sector in terms of energy usage, the understanding of the level of energy efficiency of wastewater treatment plants (WWTPs) is useful to both the industry itself as well ... -
Design and Characterization of Naphthalene Ionic Liquids
(Frontiers, 2020)Surfactants have a great number of applications. Among these chemicals, petroleum sulfonates have been widely used due to their effectiveness in reducing interfacial tension. This is the case of sodium octylnaphthalene ... -
Environmental assessment of complex wastewater valorisation by polyhydroxyalkanoates production
(Elsevier, 2020)Polyhydroxyalkanoates (PHA) are biodegradable polymers with renewable origin that are expected to substitute conventional petrochemical plastics. However, before they are commercialized, life-cycle environmental validation ... -
Monitoring of Natural Pigments in Henna and Jagua Tattoos for Fake Detection
(MDPI, 2020)Temporary tattoos are a popular alternative to permanent ones. Some of them use natural pigments such as lawsone in the famous henna tattoos. Recently, jagua tattoos, whose main ingredients are genipin and geniposide, have ... -
Tracking Bacterial Spoilage in Cosmetics by a New Bioanalytical Approach: API-SPME-GC-MS to Monitor MVOCs
(MDPI, 2020)The main goal of this work was the use of the powerful solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) technique to unequivocally identify microbial volatile organic compounds (MVOCs) derived ... -
Heavy Metal Uptake of Lettuce and Ryegrass from Urban Waste Composts
(MDPI, 2020)Interest in using urban waste composts as amendments in urban agriculture is growing nowadays. However, concerns about the potential transference of pollutants present in urban waste to the food chain are very relevant ... -
Polyhydroxyalkanoates (PHAs) Production: A Feasible Economic Option for the Treatment of Sewage Sludge in Municipal Wastewater Treatment Plants?
(MDPI, 2020)Sludge is a by-product of municipal wastewater treatment plants (WWTPs) and its management contributes significantly to the operating costs. Large WWTPs usually have anaerobic sludge digesters to valorize sludge as methane ... -
Assessment of a fast method to predict the biochemical methane potential based on biodegradable COD obtained by fractionation respirometric tests
(Elsevier, 2020)The biochemical methane potential test (BMP) is the most common analytical technique to predict the performance of anaerobic digesters. However, this assay is time-consuming (from 20 to over than 100 days) and consequently ... -
Optimization of an enriched mixed culture to increase PHA accumulation using industrial saline complex wastewater as a substrate
(Elsevier, 2020)Polyhydroxyalkanoates (PHA) appear as good candidates to substitute conventional petroleum-based plastics since they have similar properties but with the advantage of being biodegradable. Wastewater streams with high organic ... -
Assessment of the fate of organic micropollutants in novel wastewater treatment plant configurations through an empirical mechanistic model
