Closing loops in intensive livestock systems: innovative strategies for nutrient recycling and emissions reduction
(English) The exponential growth of world population is leading to a high demand of food products and, consequently, to the development of intensive agricultural and livestock systems. In this sense, synthetic fertilizers ...
Understanding size-resolved dust emission from field measurements in Morocco
(English) Atmospheric mineral dust is composed of a variety of mineral particles exhibiting distinct composition, shape, and size. The wide range of diameters exhibited by dust particles, spanning more than three orders ...
Energy and material circularity in building-integrated agriculture : an environmental approach
(English) Cities are great resource consumers and largely contribute to anthropogenic environmental impacts, urgently requiring a decarbonization plan. Urban agriculture lies on industrial ecology principles; waste resources ...
Environmental impact accounting of organic agricultural production systems: advancing inventory and biodiversity modelling approaches in life cycle assessment
(English) Agriculture not only contributes to more than a quarter of all global greenhouse gas emissions but is also the number one anthropogenic source of nitrogen emissions and a danger to nearly half of threatened ...
Use of advanced analytics for health estimation and failure prediction in wind turbines
The energy sector has undergone drastic changes and critical revolutions in the last few decades. Renewable energy sources have grown significantly, now representing a sizeable share of the energy production mix. Wind ...
Comparison of the mesophilic, thermophilic and temperature-phased anaerobic digestion of sewage sludge
Anaerobic digestion (AD) is currently spread all over the world for sewage sludge stabilisation, volume reduction and green energy production. Its implementation contributes to turn a wastewater treatment plant (WWTP) into ...
Diferent approaches to improve groundwater resources management : submarine groundwater discharge and managed aquifer recharge
Global change is expected to affect significantly the global hydrological behavior, changing mean annual precipitation patterns, increasing length of drought periods, rising evaporation and atmospheric water vapor and ...
Evaluating the impact of urban mobility policies on the air quality levels of Barcelona by means of an integrated modelling system
Persistent high levels of NO2 have severe health effects on population. These are often found in large urban conurbations with high vehicle densities. In Barcelona, with one of the highest vehicle densities in Europe, the ...
Microalgae-based wastewater treatment systems at demonstrative scale : gravity harvesting and thickening of biomass, and advanced design of bioreactors
Microalgae culture is currently receiving considerable attention for its potential in wastewater treatment and production of algal biomass from which high-value bioproducts and bioenergy can be obtained, as well as the ...
Análisis composicional del acceso a servicios de agua, saneamiento e higiene y medida de sus desigualdades
Access to water, sanitation and hygiene (WASH) services is closely linked to public health. The benefits of having safe WASH are vast. The WHO/UNICEF Joint Monitoring Program (JMP) estimates of the population accessing ...
Implementation and evaluation of the circular economy model in the construction and demolition waste sector
Construction and demolition waste (CDW) is a major environmental concern that requires immediate attention. The large volumes of CDW produced and its associated environmental effects have led to explore new alternatives ...
Spatio-temporal association of physic characteristics and chemical composition of the atmosphere with human mortality data
Air pollution is an environmental challenge that has an important influence on the life of human beings. Therefore, the development, implementation, and evaluation of new statistical approaches will improve the numerical ...
Life cycle assessment of the cabin waste management in the aviation sector
Air transport, in 2018, was the means of transport chosen by 8.8 billion people around the world. This is a sector that expected continued passenger growth in the following years, but due to the current effects of the ...
Constructed wetlands for winery wastewater treatment: Sustainability and circular economy in the wine sector
The wine industry generates large volumes of wastewater originating from various processes and operations carried out during wine production. Winery wastewater (WWW) is characterized by highly variable flows and loadings. ...
Sistemas de Gestión de Residuos Sólidos Urbanos (RSU) : Metodología para el análisis técnico-económico con valoración de las externalidades y casos de estudio
Currently, there is a serious problem due to the large generation of municipal solid waste (MSW) due to the high consumption rates of the population and the short time of use of the products. Moreover, there is poor waste ...
lntensification of mixing and homogenisation of culture medium in photobioreactors for microalgae production
Due to the large volume of the processed medium in pilot or industrial cultivation systems, it is difficult to illuminate the entire layer of the culture medium, which results in the formation of dark zones. Due to ...
Biogás para cocción a partir de la digestión anaerobia de pastos en zonas rurales de clima tropical
Energy for cooking is the most essential energy service for peasants in countries with tropical climates such as Colombia where a large number of families can only access to firewood as energy source. An alternative energy ...
Dynamics of ultrafine particles and tropospheric ozone episodes
Atmospheric aerosol particles, particularly ultrafine particles (UFPs; particles with less than 100 nm in diameter), and tropospheric ozone (O3) are atmospheric pollutants highly influenced by photochemical reactions, i.e., ...
Development and evaluation of a street-scale air quality modelling system for the city of Barcelona
Air pollution is known to cause detrimental health effects in cities and specially on the most vulnerable population. Having access to reliable air pollutant concentration data at street-level in urban areas can be crucial ...
High rate algal ponds for post-treating sewage from UASB reactors : treatment efficiency, anaerobic co-digestion and sustainability
This PhD thesis aimed at evaluating the performance of high rate algal ponds (HRAP) to post-treat the anaerobic effluent from an upflow anaerobic sludge blanket (UASB) reactor fed with sewage. The work analysed the system ...
