Provided is an eco-friendly filament using a biomass manufactured by extruding a bioplastic pellet which is formed from a bioplastic pellet composition including mixed particles including a coffee byproduct with a fatty acid content of 0.01 to 2.5 wt % or less and inorganic particles and having a size of 50 μm or less; an additive; and a plastic raw material. The inorganic particles are one or more selected from the group consisting of calcium carbonate, silica, starch, alumina, titanium dioxide, talc, kaolin, mica, sericite, zinc oxide, barium carbonate, barium sulfate, diatomaceous earth, magnesium carbonate, magnesium silicate, boron nitride, alumina, zirconium oxide, iron oxide and mica titanium. The additive is one or more selected from the group consisting of an amide-based active compound, copolyamide, ethyl methane sulfonate (EMS), ethylene bis stearamide (EBS), and D-sorbitol.

1. An eco-friendly filament using a biomass manufactured by extruding a bioplastic pellet which is formed from a bioplastic pellet composition including mixed particles including a coffee byproduct with a fatty acid content of 0.01 to 2.5 wt % or less and inorganic particles and having a size of 50
1. An eco-friendly filament using a biomass manufactured by extruding a bioplastic pellet which is formed from a bioplastic pellet composition including mixed particles including a coffee byproduct with a fatty acid content of 0.01 to 2.5 wt % or less and inorganic particles and having a size of 50 μm or less; an additive; and a plastic raw material, wherein the inorganic particles are one or more selected from the group consisting of calcium carbonate, silica, starch, alumina, titanium dioxide, talc, kaolin, mica, sericite, zinc oxide, barium carbonate, barium sulfate, diatomaceous earth, magnesium carbonate, magnesium silicate, boron nitride, alumina, zirconium oxide, iron oxide and mica titanium, andthe additive is one or more selected from the group consisting of an amide-based active compound, copolyamide, ethyl methane sulfonate (EMS), ethylene bis stearamide (EBS), and D-sorbitol. 2. A manufacturing method of an eco-friendly filament using a biomass, comprising: (a) primarily removing fatty acid by extracting coffee byproducts with a solvent;(b) secondarily removing fatty acid by mixing inorganic particles with the coffee byproducts in which the fatty acid is primarily removed;(c) grinding mixed particles including the coffee byproducts in which the fatty acid is secondarily removed and the inorganic particles;(d) preparing a bioplastic pellet by mixing and extruding the ground mixed particles, a plastic raw material, and an additive; and(e) manufacturing a filament by extruding the bioplastic pellet,wherein the solvent in step (a) is one of fermentation alcohol at room temperature, an enzymatic cleaner diluent at 55° C. or less, or water at 60° C. or higher andthe additive in step (d) is selected from the group consisting of an amide-based active compound, copolyamide, ethyl methane sulfonate (EMS), ethylene bis stearamide (EBS), and D-sorbitol. 3. The manufacturing method of claim 2, wherein in step (a), an oil absorption means is further included in the stirrer 1 which extracts the coffee byproducts with a solvent, the oil absorption means is constituted by a frame having bar or mesh inner and outer boundaries so that the coffee byproducts and the solvent flow into and out andan oil absorption portion formed in the frame so that the fatty acids in the coffee byproducts are coagulated when the coffee byproducts and the solvent flow into and out, andon the boundaries of the frame, while the coffee byproducts and the solvent flow into and out of the oil absorption means, the fatty acids of the coffee byproducts are coagulated in the oil absorption portion.
