After brewing coffee, spent coffee ground (SCG, one of the biomass) was generated, which contains abundant organic compounds. Therefore, SCG could be applied as a carbon precursor for fabricating porous biochar via carbonization. Various studies on the pore structure of carbonization SCG (CSCG) have been reported for applications to absorbents and energy storages. CSCG has exhibited high potential as a filler for thermal insulation composite due to its porous structure, but there are few studies on this. In this study, eco-friendly thermal insulation composites were fabricated with CSCG and ethyl cellulose, and the thermal insulation performance was observed using thermal imaging. The pore restoration method using a volatile solvent (ethanol) was applied to maintain the pores of the incorporated filler, which is an important factor in thermal insulation property. The fabricated CSCG-based composite can be expected to be a new alternative to eco-friendly thermal insulation materials.
