Anaerobic digestion (AD) is a widespread technology for treating high strength waste streams, such as livestock manure. AD has some limitations: i) high nutrient concentrations in effluents (especially nitrogen and ...
The meat sector is one of the most important industrial sectors in Europe and it is associated with the generation of large quantities of animal by-products not intended for human consumption (ABPs). The increasing demand ...
In Chapter 1 of the thesis the responsibilities of the main actors involved in the decision-making are identified, listed and described, stressing that there are many actors involved in the decision-making. Also, there is ...
Climate Change has become no longer a conjecture but an objective reality. The increase of the global average temperature, the seas level rise or the increase in the frequency and magnitude of extreme weather events are ...
This thesis is a interdisciplinary research in the field of sustainable energy systems with the falsifiable hypothesis "a necessary transition from a society highly dependent on oil to one based on the use of local resources ...
The energy renovation of buildings is an essential action to achieve the European target of 20/20/20. However, the dynamics of the energy renovation are very slow and the development of urgent policy actions beyond the ...
The water quality status of an Andean river basin was characterised and the pressures from anthropogenic activities were evaluated to enhance the available knowledge of the environment within an ecosystem in Peru. This ...
Based on the experience gained during more than 10 years working on energy efficiency in public buildings of various uses, this thesis develops a methodology for intervention in school buildings. The aims were to define ...
An optimal strategy for monitoring water quality should be based on a combination of different technologies depending on the particularities of the system being observed. The final solution will be a combination of laboratory ...
A microbial fuel cell (MFC) is a bioelectrochemical system (BES) capable of converting the chemical energy contained in the chemical bonds of a substrate into electrical energy by means of electrochemical reactions catalyzed ...
In the last years, international and national policies have been developed in order to encourage the improvement of energy efficiency. They have also been developed in order to reduce the environmental, economic and social ...
During April-May 2010, the eruption of Eyjafjallajokull volcano in Iceland caused the larger breakdown of civil aviation after World War II. Although the eruption was weak in intensity, the dispersal of volcanic ash clouds ...
Intensive fish culture in floating cages is one of aquaculture activities that has grown fastest in recent years. However, this activity produces impacts ranging from alterations in the natural environment to social and ...
Water is a limited resource essential for life. Human activities have been exercising considerable pressures on it. The unsustainable use and the need to improve the management of water are among the largest global concerns ...
Constructed Wetlands (CWs) are a wastewater treatment technology that inherits the purification potential of natural wetlands and optimizes it to comply with regulations for treated discharges. CWs have become an equally ...
Access to energy is crucial to human welfare; no residential, commercial or industrial activity can be conceived without energy supply. At the same time, current dependence on fossil fuels and their negative effects on ...
El incremento de la utilizaci on de la energ a solar como fuente de generaci on de energ a requiere de una adecuada estimaci on de la radiaci on solar global y directa incidente en la super cie terrestre. La estimaci on ...
The research aims to define a theoretical model of a resilient neoecosystem analyzing the relationship between water and urban form. The hypothesis is to understand the characteristics of a resilient model for the evaluation ...
Anaerobic digestion is a biochemical process that transforms diverse categories of biomass feedstock to renewable energy, in the form of methane, and contributes to resources conservation and greenhouse gases emission ...
Nowadays, around 690 million undernourished people worldwide, even though the world already produces enough food to feed more than the whole current population. This situation is far from diminishing due to the current ...
