Abstract Scope |
Global consumption of coffee is over 11 million metric tons annually which produces an exuberant amount of carbon rich biomass. To reclaim the spent grounds, this research demonstrates a simplistic method to structurally tune carbon black as a filler for a recyclable polymer. Spent espresso grounds (SEG) are treated with 5% metal salt and then pyrolyzed at 15℃ per minute up to 1000℃ with an isotherm of three hours. After removal of catalyst, filler is mechanically mixed with polymer in solution for adequate distribution of particles. After mixture is dried and pelletized, the composite pellets are extruded into a filament. After mechanical and thermal characterization, filaments demonstrated significant increase in thermal stability with relative mechanical properties compared to the neat polymer filaments. |
