Projecte d’integració de la fracció bioresidu in Castelló de la Plana’s selective waste collection system
[ES] Bio-waste is the biodegradable fraction of municipal waste (UK). Currently, in many cities, they are still collected together with the remaining fraction, so a large amount of bio-waste goes to landfills. Separate collection of this fraction would facilitate recycling. This would bring a number...

Sustainable catalytic processes for the transformation of Biomass Derivates into Chemicals
ligno-cellulosic biomass from agricultural and forestry residues is presented as an alternative for the production of chemicals and fuels, thus reducing our dependence on fossil-based raw materials. However, biomass recovery processes are currently more costly than conventional petrochemical process...
Study of the catalytic activity of molybdenum and vanadium oxides on TiO2 for the recovery of ethanol
[ES] In recent years, the uncontrolled increase in emissions of carbon oxides into the atmosphere, largely due to the use of fossil fuels, is one of the main problems facing society. In order to reduce these emissions, the use of renewable sources, such as the use of biomass and derivatives, has bec...
The production of knowledge on pesticides in European legislation
This article presents a critical approach to the rules for producing knowledge on the harmfulness of plant protection products in European law. Within the theoretical framework borrowed from sociology, agnotology, it shows that the lack of awareness of the origin of European standards and their lega...

In vitro pulmonary model design
[ES] “Chip organs are biomimetic microengineering systems containing microfluid carcases coated with living human cells, replicating key functional units of living organs to reconstitute integrated physiopathology at the level of human organs in vitro”. These microdevices can be used to test the eff...
Assessment of cocoa growers' farm management practices in Ondo State, Nigeria
This study assesses the farm management practices of cocoa growers in Ondo State, southwestern Nigeria. One hundred and twenty three farmers were selected (using simple random sampling) from the list of cocoa farmers belonging to the Cocoa Farmers' Association of Nigeria (CFAN) in Ondo State. All we...
Metal Nanoparticles Wrapped on Defective Nitrogen-doped Graphitic Carbons as Highly Selective Catalysts for C02 Hydrogenation
[EN] Considering the depletion of fossil fuels and the increasing atmospheric CO2 concentration, CO2 hydrogenation is a promising way to convert CO2 into value-added carbon-containing chemicals and fuels. Taking into account the significant influences of the particle size, chemical composition, natu...
Analysis and improvement of working processes through the implementation of continuous improvement programmes and lean manufacturing in a chemical manufacturing company
[ES] The TFG will describe the company, its organisation chart, its production and logistics system and its main processes. The student will analyse the initial situation of the company and identify the problems in the work processes and its causes. Improvements based on the Lean Manufacturing manag...
Design of a dual ultrafiltration-adsorption system for the treatment of currents from a process in the textile industry. Design flow rate 10 m³/day
[ES] The textile industry is one of the most polluting industrial sectors due to its emission to the medium of large volumes of waste water generated in its processes, in which chemicals are applied among other compounds. In addition, due to the dispersion of the sector, effluents are produced with...
an approach to sustainability from organic
Organic as an agricultural practice goes beyond its implications, the mere fact of production, since it is based on agro-ecological principles closely linked to sustainability. Within the market economies of developed countries, consumer segments are increasingly calling for products coming from non...
