Abstract: The purpose of this research was to study hydrolysis and acidogenesis of chicken skin and chicken intestine products from slaughterhouse poultry factory by means of anaerobic digester. The f i t part focused on biochemical methane potential and the second part studied about hydrolysis and acidogenesis in anaerobic CSTR digester.Biochemical methane potential (BMP) test can be used as a valuable tool to study the efficiency of anaerobic digestion process and estimate biodegradability of waste. Ground chicken intestine, chicken intestine, ground chicken skin and chicken skin were tested for BMP. The methane yields were 343,277,214, and 207 ml CH$g COD added, respectively, corresponding 88.1,71.0,54.8 and 53.0 percent of theoretical values. Size reduction of waste showed an acceleration of digestion process. The study of hydrolysis and acidogenesis of chicken skin and chicken intestine focused on the role of nutrient supplementation, using laboratory CSTRs with totaI volume of 3 litres and Iiquid volume :of 2 litres. The reactors were semi - continuous fed with organic loading rate of 1 kg CODn-d and hydraulic retention time of 20 days. Four CSTRs were used for 2 different wastes and 2 different nutrient supplementations (type I and 11). Ground chicken intestine and ground chicken skin were taken as samples. Both macronutrients and micronutrients were supplemented into all reactors but the difference of nutrient supplementation is that the concentation of micronutrient of the type 11 was 10-fold increase of those of the type I. The methane production were not different at the early period. Then, reactors with the nutrient type I could not continuously produce methane and VFAs accumulated while continuously methane production in the reactors supplemented with nutrient type II were experienced until the end of experiment. The results suggested that micronutrients were limited in the reactors supplemented with nutrient type I. Hydrolysis percentage in this experimentwere 19.8,58.9, 13.1 and 21.7 percent for I) ground intestine and nutrient type I, 2) ground intestine and nutrient type II, 3) ground skin and nutrient type I and 4) ground skin and nutrient type 11, respectively. Methane yields were 0.38 and 0.127 Vg VS added for ground chicken intestine and ground chicken skin and nutrient type TI, respectively. The result also suggested that the limiting step for methane production was the methanogenesis of VFAs for the nutrient type I but hydrolysis and acidogenesis for the nutrient type II.
