Biodegradation potential of bulking agents used in sludge bio-drying and their contribution to bio-generated heat.


Straw and sawdust are commonly used bulking agents in sludge composting or bio-drying. It is important to determine if they contribute to the biodegradable volatile solids pool. A sludge bio-drying process was performed in this study using straw, sawdust and their combination as the bulking agents. The results revealed that straw has substantial… (More)
