In this study, the effects of biochar amendment on swine manure composting performance at temperatures in the -5 degrees C-15 degrees C range was investigated. Monitoring result showed biochar addition significantly prolonged thermophilic stage duration to meet harmless standards of livestock manure compost at 5 degrees C, assisting a seemingly difficult composting to succeed. Additionally, from viewpoint of thermal balance, biochar increased organic matter degradation derived heat from 50.4% to 86.5% and water vaporization heat from 29.6% to 73.5% while decreasing heat exchange by two-fold. Overall, the results presented herein indicated that biochar has potential to play a positive role in amelioration of animal manure composting at relatively low ambient temperature and provide insight into how biochar influences heat generation and flow during composting. |
