The invention provides a degradation method for polyethylene plastics, comprising the following specific steps: S1. Screening collected plastic raw materials, cleaning them thoroughly, and mechanically crushing them to reduce volume; S2. Soaking the pretreated raw materials in a soaking solution for 24–72 hours at a soaking temperature of 37–60°C; S3. Cleaning the soaked raw materials and putting them into a fermentation tank for fermentation degradation; S4. Collecting the degraded mixed liquid for secondary extraction and recycling. The invention enables convenient and repeated recycling of plastics. After treatment, waste plastics can be remade into products or processed into gasoline and diesel, effectively solving environmental and social problems caused by plastic pollution.
