Abstract—The optimization of Bio-SRF is conducted by mixing sewage sludge with waste sawdust and coffee grounds to improve high moisture content and low calorific value. grounds(1~5g).This study was aimed at put the sewage sludge(2~10g), waste sawdust(1~5g) and coffee grounds(1~5g) as variables using RSM (Three-dimensional analysis & Central composite design).The result is [sewage sludge(2.0g), waste sawdust(1.0g), coffee grounds(5.0g)] and 0.9872 as R-square(adj). Forecast data is reported 4,574.26 kcal/kg above the condition.

Index Terms—Response surface method, waste biomass, bio-SRF, high calorific fuel.
