After the first stage of the project, which consisted in conducting preliminary studies and calculations for the construction of the plant on the premises of the Centre for Waste Management of Lorca (Murcia, Spain), we have developed two complete cycles of approximately one year to which six months must be added to account for filling hydrolysate tanks.
The process consists, broadly speaking, in the mixing and processing of different by-products and waste, resulting in a final energy production.
First, slaughterhouse waste and animal carcasses are subjected to a novel process called hydrolysis, in which the natural process of decomposition is accelerated by the addition of natural coadjuvants, being reduced to an organic-mineral broth, to be used in co-digestion with sewage sludge and slurry to produce biogas.
In addition to biogas, this process generates a digested by-product called digestate that, once mixed with pruning debris and waste wood, is transformed into pellets that are burned in a biomass boiler, resulting in three products:
In each cycle, a comprehensive set of analysis and technical and economic studies will be conducted to optimize the process.
