The invention provides an effective method for plastic degradation, including the following specific steps: S1. Screening and cleaning collected plastic raw materials, and conducting mechanical crushing to reduce their volume; S2. Soaking the pretreated raw materials in a soaking solution for 24‑72 hours at a constant soaking temperature of 37‑60℃; S3. Cleaning the soaked raw materials and adding them into a fermentation tank for fermentation and degradation; S4. Collecting the degraded mixed liquid for secondary extraction and recycling. The invention enables plastics to be easily recycled and reused repeatedly. After recycling and treatment, waste plastics can be remade into finished products or processed into gasoline and diesel, effectively solving environmental and social problems caused by plastic pollution.
