The paper presents the results of experimental approach on chicken farms residues for energy generation. Based on complete thermal-physical-chemical characterization a series of waste to energy conversion chains are proposed as alternative to incineration disposal solution. The researched focused on combustibility properties quantification for the appropriate waste to energy chain identification. The experiments were carried out for elemental composition, primary analysis and calorimetric characteristic establishment. The important water content (up to 70%) makes impossible the energy recovery via direct combustion - steam turbine cycle. The research focused on new conversion processes as pyrolysis, enabling the use of gasification and Brayton or Otto-Diesel thermodynamic cycles.
