LA DIGESTION ANAEROBIA (DA) ES UNA TECNOLOGIA MADURA EMPLEADA EN NUMEROSAS INSTALACIONES A LO LARGO DE TODO EL MUNDO PARA EL APROVECHAMIENTO ENERGETICO DE CORRIENTES RESIDUALES CON ALTA CARGA ORGANICA. SIN EMBARGO, LA DA PRESENTA DOS LIMITACIONES FUNDAMENTALES: EN PRIMER LUGAR, LA SENSIBILIDAD DE LOS MICROORGANISMOS METANOGENOS A MODIFICACIONES EN FACTORES AMBIENTALES COMO EL PH, SOBRECARGAS ORGANICAS O ELEVADAS CONCENTRACIONES DE SALES, PUEDE CONDUCIR A UNA ACUMULACION DE ACIDOS GRASOS VOLATILES, Y POR LO TANTO A UNA PARADA DEL PROCESO. EN SEGUNDO LUGAR, LA RECALCITRANCIA O BAJA DEGRADABILIDAD DE CIERTOS RESIDUOS ORGANICOS, ACOTA EL CAMPO DE APLICACION DE DA A AQUELLOS RESIDUOS FACILMENTE DEGRADABLES. _x000D_ CON LA EJECUCION DE ESTE PROYECTO PRETENDEMOS DAR UNA RESPUESTA A ESTE DOBLE DESAFIO MEDIANTE LA APLICACION DE TECNOLOGIAS DE BASE ELECTROQUIMICA Y BIOELECTROQUIMICA. EN PRIMER LUGAR NOS PROPONEMOS INTEGRAR LA ELECTROLISIS BIOCATALITICA CON LA DA CON EL OBJETIVO DE MEJORAR LA ROBUSTEZ Y LA ESTABILIDAD DE LOS PROCESOS DE DIGESTION ANTE SOBRECARGAS ORGANICAS E INCREMENTAR LA PRODUCCION DE PROPORCION DE METANO OBTENIDO EN EL BIOGAS (TAMBIEN SE CONSIDERA EL EMPLEO DE PARTICULAS DE BIOCHAR PARA FAVORECER ESTA ULTIMA). EN SEGUNDO LUGAR, SE PRETENDE DESARROLLAR UN PRETRATAMIENTO DE ELECTROXIDACION PARA MEJORAR LA DEGRADABILIDAD DE CIERTOS RESIDUOS ORGANICOS Y PODER AMPLIAR ASI EL RANGO DE SUSTRATOS SUSCEPTIBLES DE SER EMPLEADOS EN DIGESTION ANAEROBIA. ESTE PRETRATAMIENTO SERA INTEGRADO CON UN BIOCATODO CON EL OBJETIVO DE HACER USO DE LOS ELECTRONES GENERADOS DURANTE LA ELECTROXIDACION PARA LA BIOELECTROSINTESIS DE COMPUESTOS ORGANICOS. ADEMAS, NOS FIJAMOS COMO OBJETIVO, EL EMPLEO DE MATERIALES DE BAJO COSTE Y OPTIMIZAR EL BALANCE ENERGETICO DE AMBOS PROCESOS PARA ASI, FOMENTAR LA ESCALABILIDAD Y LA APLICABILIDAD DE LAS TECNOLOGIAS PROPUESTAS.

ANAEROBIC DIGESTION (DA) IS A MATURE TECHNOLOGY USED IN NUMEROUS INSTALLATIONS AROUND THE WORLD FOR THE ENERGETIC USE OF RESIDUAL STREAMS WITH HIGH ORGANIC LOAD. HOWEVER, THE DA DA HAS TWO FUNDAMENTAL LIMITATIONS: FIRSTLY, THE SENSITIVITY OF METHANEGEN MICROORGANISMS TO CHANGES IN ENVIRONMENTAL FACTORS SUCH AS PH, ORGANIC OVERLOADS OR HIGH SALT CONCENTRATIONS CAN LEAD TO AN ACCUMULATION OF VOLATILE FATTY ACIDS, AND THUS TO A STOP IN THE PROCESS. SECONDLY, THE RECALCITRANCE OR LOW DEGRADABILITY OF CERTAIN ORGANIC WASTE LIMITS THE SCOPE OF APPLICATION TO EASILY DEGRADABLE WASTE. _x000D_ with THE IMPLEMENTATION OF THIS PROJECT we intend to give an answer to this double disaffeency by means of the application of electronic and bioelectrochimic base technology. IN THE FIRST PLACE WE PROPOSE TO INTEGRATE BIOCATALITICA ELECTROLYSIS WITH THE OBJECTIVE OF IMPROVING THE ROBUSTNESS AND STABILITY OF DIGESTION PROCESSES IN THE FACE OF ORGANIC OVERLOADS AND INCREASING THE PRODUCTION OF METHANE PRODUCTION OBTAINED IN BIOGAS (THE USE OF BIOCHAR PARTICLES IS ALSO CONSIDERED TO FAVOR THE LATTER). SECONDLY, THE AIM IS TO DEVELOP A PRE-TREATMENT OF ELECTROXIDACION IN ORDER TO IMPROVE THE DEGRADABILITY OF CERTAIN ORGANIC WASTE AND THUS TO EXPAND THE RANGE OF SUBSTRATES THAT CAN BE USED IN ANAEROBIC DIGESTION. THIS PRETREATMENT WILL BE INTEGRATED WITH A BIOCATODO WITH THE AIM OF MAKING USE OF THE ELECTRONS GENERATED DURING THE ELECTROXIDACION FOR ORGANIC COMPOUNDS BIOELECTROSINTESIS. IN ADDITION, WE AIM TO USE LOW-COST MATERIALS AND OPTIMISE THE ENERGY BALANCE OF BOTH PROCESSES IN ORDER TO PROMOTE THE SCALABILITY AND APPLICABILITY OF THE PROPOSED TECHNOLOGIES. (English)
