A biodegradable composite may include a biodegradable plastic polymer having a biodegradability of from about 80 percent (%) to about 95% when measured according to a biodegradability test in accordance with an ASTM D6400-19 standard and a bio-derived fiber. A polymeric matrix of the biodegradable plastic polymer may have a tensile strength of from about 30 MPa to about 45 MPa and an elastic modulus of from about 2600 MPa to about 3600 MPa. The bio-derived fiber may have a tensile strength greater than the tensile strength of the polymeric matrix of the biodegradable plastic polymer and an elastic modulus greater than the elastic modulus of the polymeric matrix.
