Using a mixture of sewage sludge and woody waste, optimal conditions for the bio-briquette process of carbonization residue were evaluated by compressive strength and bulk density. For the bio-briquette process, the optimal conditions were determined to be a molding temperature of 110oC and a moisture content of 10%. As the lignin in the carbonization residue can be used as a natural binder because of its plasticizing property, the bio-briquette process uses this property. To increase the compressive strength to >3.50 MPa, binders such as polyvinyl alcohol (PVA), guar gum, and starch were mixed in the carbonization residue. At 3 wt.% of PVA, 3 wt.% of guar gum, and 5 wt.% of starch, the conditions of binder usage were evaluated. To examine the cost in the bio-briquette production with the addition of the binder, the proportion of binder cost for the bio-briquette production were evaluated at 9.2% for PVA, 8.6% for guar gum, and 3.3% for starch, and starch was determined to be the best binder for the bio-briquette process.
