The paper presents the results of experimental approach on organic waste from food industry processing for complete neutralization, energy generation and disposal. Non-oxidant processes pyrolysis based were conducted both at laboratory and pilot scale aiming for product complete neutralization with respect to pathogen germs, bio-degradation and medium-long term storage risk. The results of the study represent alternatives to currently used disposal solutions mainly based on incineration. For the experimental analysis three main waste types were considered: primary stage processing meat industry (feathers), second stage processing meat industry (bones). Noticeable quantities of organic residues such as feather, bone meal, blood and offal waste are generated by poultry processing industries. These residues making up about 25% to 37% of initial product body weight are a considerable waste of the meat processing industry, due to high specific volume, being produced about million tons per year world-wide. Disposal of chicken meat processing industry is a major concern and accumulation of important waste quantities results in environmental pollution of soil, water and air with direct impact on human health. Depending on processing costs the industry sector uses the incineration (usually provided by specialized companies) or the production of meat and bone meal. To limit the risk of disease transmission via feed and food chain the recovery of organic materials for animal feed is banned. The incineration presents the major disadvantage of important energy consumption due high water content of the product together with polluting emissions and low efficiency if energy recovery is used. For the incineration process support fuel is required due to low combustibility properties of the product. With respect to landfiling the products are considered as difficult substrates for anaerobic digestion because of their high protein and lipid content which are inhibitory for the process.The research focused on the influence of thermal treatment process parameters on product neutralization efficiency and pyrolysis by-products physical-chemical characteristics with respect to energy potential recovery.
