Resumo: This study aimed to conclude about the performance and effectiveness of co-anaerobic digestion solutions applied to decentralised management of residual flows of livestock production, agricultural and agro-industries. Therefore, it was considered the anaerobic co-digestion of two waste streams produced in the same geographic area within an intensive pig production region, with a logical approach to industrial ecology. For the working base model of co-digestion with pig slurry (ChS), it was chosen the waste stream of pears and apples (RPM) from the rejection and selection processes of centralised fruit storage and distribution facilities, and the oily exudate from the industrial cooking process of sardines (ECS) of a sardine cannery factory. A comprehensive study of water use and production of manure on pig farms was conducted in order to conclude about the average quality of pig slurry produced in Portugal. From the several trials developed, it was concluded that residues of pears and apples after a bioconversion pre-treatment (BRPM) are an excellent co-substrate. With a composition (v/v %) BRPM:ChS of 30:70 and 66:34, it was increased respectively 3 and 3,6 times the productivity of the digester, when compared with the performance achieved only with pig slurry. The anaerobic co-digestion of BRPM in with ChS resulted in a national patent. From the experiments that used wasted sardine oil (ECS) as co-substrate it was concluded that a mixture composition (% v/v) ECS:ChS of 5:95, could increase in a 3,7 fold the productivity of the digester, when compared with the one achieved only with pig slurry. In order to transpose these studies to more realistic conditions, a mobile pilot plant was designed in order to develop in natural operation conditions similar assays in a pig farm. This anaerobic digestion mobile unit was also patented. The pilot study demonstrated the technical feasibility to develop anaerobic co-digestion processes using the waste stream of pears and apples and the exudate from the industrial cooking process of sardines with pig manure, and to manage it in a decentralised model throughout the year.
