Environmental assessment of viticulture waste valorisation through composting as a biofertilisation strategy for cereal and fruit crops
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
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 ...
Model-based design of smart active packaging systems with antimicrobial activity
Smart active packaging is an innovative packaging system that combines the benefits of measuring, estimating or predicting different aspects of food quality or safety with the release of an active substance that extends ...
A metabolic model for targeted volatile fatty acids production by cofermentation of carbohydrates and proteins
Anaerobic mixed-culture fermentations are interesting processes to valorise organic wastes by converting them to volatile fatty acids. One of the main issues is that certain operational conditions (e.g. pH or different ...
Digested blackwater treatment in a partial nitritation-anammox reactor under repeated starvation and reactivation periods
Wastewater source-separation and on-site treatment systems face severe problems in wastewater availability. Therefore, the effect of repeated short-term starvation and reactivation periods on a partial nitritation-anammox ...
Towards a digital twin: a hybrid data-driven and mechanistic digital shadow to forecast the evolution of lignocellulosic fermentation
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 ...
Determination of N-Nitrosamines by Gas Chromatography Coupled to Quadrupole–Time-of-Flight Mass Spectrometry in Water Samples
An analytical method based on high-resolution quadrupole–time-of-flight (QToF) mass spectrometry has been developed as an alternative to the classical method, using a low-resolution ion trap (IT) analyzer to reduce ...
Análisis de ciclo de vida y huella de carbono. Casos prácticos

Environmental assessment of complex wastewater valorisation by polyhydroxyalkanoates production
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 ...
