In order to optimize bio-waste management in the region of Lafões (Portugal), comprising a large production of forestry and poultry production residues, complementarities were explored between the two bio-waste streams with respect to biogas production and energy recovery.
The forestry biomass potential was assessed through a methodology using Geographic Information System data together with technical, land use and accessibility information. The poultry biomass potential was estimated according to IPCC guidelines. The energy potential of these biomass sources was assessed through bench-scale anaerobic digestion assays with single and mixed substrates.
Conclusions are presented regarding the complementarity between these bio-wastes as bio-energy sources relevant for the Lafões region, showing increased energy potential through co-digestion.
