[0002] With the rapid advancement of global industrialization, the widespread use of plastics and other synthetic materials has greatly promoted the convenience of production and life, but it has also brought serious environmental problems. In particular, plastic waste, due to its non-degradable nature, has accumulated in nature for a long time, causing serious pollution to the soil, water sources and ecosystems. In addition, traditional plastic disposal methods, such as incineration and landfill, not only occupy a large amount of land resources, but may also release toxic gases, further exacerbating environmental pollution.

[0003] In recent years, with the enhancement of environmental awareness and the popularization of the concept of sustainable development, waste recycling has become one of the key ways to solve the above problems. The recycling of waste plastics, paper, cloth, sawdust and other materials can not only reduce the demand for new raw materials and reduce resource consumption, but also effectively reduce the environmental burden and achieve a win-win situation of economic and environmental benefits.

[0004] However, recycling waste is not an easy task. Different types of waste have significant differences in physical properties, chemical composition and degree of contamination, which brings great challenges to recycling. In particular, waste plastics, due to their wide variety and complex composition, often require tedious pretreatment and classification to meet the requirements of subsequent processing.

[0005] In response to the above problems, researchers in the industry continue to explore and innovate, aiming to develop an efficient and environmentally friendly method of waste recycling. Summary of the invention

[0008] a. Prepare the objects to be crushed;

[0009] b. The material to be crushed is conveyed to the crusher via a conveyor belt for crushing and iron removal. The material to be crushed is crushed to a size of 10cm*20cm using a double 90kw crusher. The material to be crushed is crushed to a size of 3cm*5cm using a double 45kw crusher for the second crushing.

[0010] c. The crushed materials after secondary crushing are conveyed to the granulator through a conveyor belt for granulation, and the granulated materials with particle sizes of 4mm, 6mm, 8mm, 10mm and 12mm are obtained, which are classified and placed for standby use;

[0011] d. The obtained pelletized material was fed into an internal mixer and kneaded for 5-8 minutes. When the temperature reached 150 degrees Celsius, a hot material was obtained.

[0012] e. The hot material is conveyed to the extrusion roller by a conveyor belt to obtain an extrudate, wherein the size of the extrudate is 0.5mm*3mm;

[0013] f. The extrudate is cooled to 30-50°C by water and then rolled up to obtain an intermediate coil;

[0014] g. The coils are subsequently processed to obtain finished products;

[0015] h. Place the processed finished products in a cool, dark and ventilated place, package them, and store them in the warehouse.

[0016] Furthermore, the materials to be crushed in step a include waste plastics, PE, OPP, PVC, woven bags, paper fibers, rags and wood chips.

[0017] Furthermore, the extrusion roller in step e comprises a smooth roller and an anilox roller, wherein the mesh diameter of the anilox roller is 1 mm.

[0018] Furthermore, in step f, the diameter of the coil is ≤70 cm.

[0019] Furthermore, the processing method of the coil in step g includes trimming and slicing and / or slitting. The trimming and slicing process obtains a plate with a size of 1m*2m, and the slitting process obtains a coil with a size of 1m*10m or 1m*15m.

[0020] Furthermore, the packaging method in step h includes packaging plates with a size of 1m*2m with a pallet, and packaging coils with a size of 1m*10m or 1m*15m with a shrink film.
