The sugar cane and poultry industry are generators of a large amount of byproducts that can have their added value enhanced when used as an energy source. Thus, the objective of this study was to investigate the effect on anaerobic biodigestion of sugarcane bagasse in natura and pretreated with sodium hydroxide, using chicken excreta as inoculum. To do this, 600mL experimental biodigesters were used, with two treatments: 1 - sugarcane bagasse inoculated with bird excreta and 2 - sugarcane bagasse inoculated with bird excreta and added 4% sodium hydroxide solution (NaOH). The chemical composition of sugarcane bagasse and bird excreta were analyzed, as well as how the reactive sludge (substrate) were evaluated, before and after the period of 54 days. The variables of pH, DQO, total, volatile and fixed solids and also the production of methane gas (CH4) were analyzed. The results show that the treatment with 4% sodium hydroxide (NaOH) pretreatment presented better results in methane gas production and environmental evaluation parameters.
