The invention discloses a method for processing waste plastics into plastic particles, comprising the following steps: Step 1: Put the recycled waste plastics into an acid pool, soak for 1 day, and then take them out; Step 2: Rinse the waste plastics treated in Step 1 with clean water and dry them in the sun; Step 3: Crush the waste plastics treated in Step 2, feed them into a twin-screw extruder, and perform granulation to complete the processing of plastic particles. In the invention, the waste plastics are first put into an acid pool for acid pickling to remove impurities and metal particles on the waste plastics, improve the cleanliness of the produced plastic particles, and expand the application scope of the plastic particles. The invention can effectively recycle waste plastics and enhance waste utilization.
