RESUMO/ABSTRACT

Co-digestion of organic waste is a technology always more frequently applied for simultaneous treatments of several solid and liquid organic wastes. In a coigestion process the content of nutrients, as well as the negative effects oftoxic compounds, can be balanced, increasing the gas yield. Moreover, co-digestion may contribute to a more efficient use of anaerobic digestion (AD) reactors and cost-sharing by processing multiple waste streams in a single facility. The aim of this study is to investigate the biogas production from mixture of Poultry Manure (PM) and Cheese Whey Wastewater (CWW). Batch experiments were performed under mesophilic conditions (37oC) at a pH from 6,5 to 7,5. The methanogenic reactor was operated at hydraulic retention time (HRT) 35 d. The trend of volatile solids (VS) have been verified.
