The invention discloses a biodegradable tableware which contains the following components in weight percentage: 30-60% of starch, 2.5-7% of low-density polyethylene, 20-42% of polyethylene, 1-3% of polyethylene wax, 1-2% of glyceryl monostearate, 3-5% of ethylene-vinyl acetate copolymer, 1-3% of titanium white powder, 2-6% of light calcium carbonate, 1-3% of talc powder, 0.2-0.5% of Al-Ti composite coupler, 0.01-0.02% of modifier, 0.1-0.2% of anti-oxygen agent and 0.04-0.06 of antioxidant. The invention also discloses a method for processing the biodegradable tableware. The method comprises the steps of proportioning, mixing and melting at high speed, extruding and tabletting, molding under positive pressure, trimming and finishing, etc. The invention modifies the formulation and the corresponding production process, so that the biodegradable tableware is not fragile and has high mechanical strength. The biodegradable tableware has water-proof and oil-proof functions without needing inner coating, and can be degraded completely in a short degradation period.
