project - EIP-AGRI Operational Group
Bovine livestock waste recovery and reuse
Valorización de residuos y recuperación material de deyecciones ganaderas de vacuno
Objectives
The main objective of the project is the development and optimisation of the cattle manure biodrying process with the aim of obtaining a biofuel suitable for use in conventional biomass boilers.
Objectives
El principal objetivo del proyecto es el desarrollo y optimización del proceso de biosecado de estiércol de vacuno con el fin de obtener un biocombustible apto para ser utilizado en calderas convencionales de biomasa.
Activities
1) Design for the subsequent adaptation of part of the composting plant as a biodrying pilot plant.
2) Construction of the biodrying pilot plant based on modifying one of the existing trenches in the composting plant.
3) Implementation and optimisation of the biodrying and co-biodrying process.
4) Solar drying pilot tests.
5) Combustion of the new biofuel. Combustion of the biodried material was carried out and gas emissions analysed to ensure they were below the legal threshold.
6) Technical, environmental and economic assessment of the process using life cycle analysis (LCA) and cost cycle analysis techniques.
Activities
1) Diseño para la posterior adaptación de parte de la planta de compostaje en piloto de biosecado.
2) Construcción de la planta piloto de biosecado a partir de la modificación de una de las trincheras existentes de la planta de compostaje.
3) Puesta en marcha y optimización del proceso de biosecado y co-biosecado. L
4) Pruebas a escala piloto de secado solar.
5) Combustión del nuevo biocombustible generado (para asegurar que las emisiones se encuentran por debajo del umbral determinado por la ley)
6) Evaluación técnica, ambiental y económica del proceso mediante técnicas de Análisis de Ciclo de Vida y Análisis de Ciclo de costes.
Context
In recent years the livestock population has significantly increased in Catalonia, while the useful agricultural surface area has decreased. Therefore, in high-density livestock areas it is necessary to develop and implement technologies that enable excess livestock excrement that cannot be safely used as fertiliser to be reused. An option for the use of this excrement is the application of the biodrying process for energy recovery. Biodrying as applied in the livestock industry is an innovative process that yields a biofuel (LHV > 2,500–3,500 kcal/kg) that can be used in conventional biomass boilers. Biodrying is similar to composting, but its final objective is different. While the aim of composting is to maximise the stability of organic waste through the mineralisation of organic carbon, that of biodrying is to use the metabolic heat produced by the biological activity to remove water from the waste matrix in the shortest time possible, minimising the degradation of carbon and preserving the majority of the heat value of the matrix.
