Use of Castor Oil Plant Pie for Solid Biofuel Production

Abstract

The objective of this study was the characterization, analysis and compaction of residues from castor oil plant pie extraction to verify its potential as solid biofuel. The chemical analysis, the mechanical test and the gross calorific value had satisfactory results. With the extraction of residual oil of the material there was a decrease on the high heating value. The produced briquettes presented good longitudinal expansion as well as mechanical strenght, however the presence of residual oil had influence on their strenght. In conclusion, the castor oil plant pie possesses energetic characteristics suitable for solid biofuel production, in addition it contributes with the reduction of industrial waste amount.
