The preliminary experimental results showed that the biodegradation capability of BL was strongly enhanced due to the leachate recirculation and moisture content adjustment. As compared with CL, BL could increase 75% landfill gas amount and approximately 4 fold landfill volume reduction, and faster leachate stabilization. Finally, the current status of refuse treatment technologies in China was analyzed, and the potential application of BL technology in China was investigated as well.
