초록

Biochemical methane potential (BMP) of residual wastes from transesterification was tested to safely recycle carcassvia rendering process. The carcass was obtained from a buried site for avian influenza (AI) infected poultry. Renderedlipid generated by a pilot-scale high-pressure rendering process was the main source of transesterification for biodieselrecovery. To test the feasibility of waste-to-energy approach for AI infected carcass, we compared the BMPs of variousfractions of rendered materials from the carcass. BMP and specific methanogenic activity results indicate thattransesterification waste shows better digestibility than that of rendered lipid, and the digestion performance wascomparable to that of liquid residue. Biogas yields of glycerol, rendered lipids, and liquid residue were estimated as 0.11 L/g chemical oxygen demand (COD), 0.06 L/g COD, and 0.17 L/g COD, respectively. Regression analysis support thatbiogas production rate of glycerol (21 mL/g COD/d) was much faster than that of lipid (7 mL/g COD/d) while that ofliquid residue was similar (24 mL/g COD/d). In summary using transesterification waste as a bioresource for bioenergyconversion can be a viable and sustainable option for the complete termination of burial site.
