The 2021 report of the UN Environment Program shows that between 1950 and 2017, the world produced a total of about 9.2 billion tons of plastic, and about 7 billion tons became plastic waste. The plastic recycling rate is less than 10%, and more than 70% of plastics are directly discarded in the soil, air, and ocean, causing serious “white pollution”.
Therefore, how to reduce plastic pollution and realize the recycling of waste plastics is a common issue facing the world.
PART 1 Classification and Main Sources of Plastic Recycling
Different types of recycled plastics have different recycling sources due to their different application fields.
At present, waste PET, waste PE, and waste PP are the main components of waste plastic recycling in China, accounting for 70% in 2021.
PART 2 Distribution of Plastic Recycling Types
The main types of recycled plastics include PET, PE, PP, PVC, ABS, etc. Among them, the first three types of waste plastics are the main types of recycling.
Among the waste PET recycling volumes, waste PET bottles have the largest volume, about 4 million tons. Accounting for 21%, and other waste PETS account for 1.5 million tons, accounting for 8%.
PART 3 Main Technologies for Plastic Recycling: Plastic Granulator
After centralized recycling of plastics, the first step is fine shredding, which is the key to the success or failure of subsequent resource processing processes.
After being sorted and crushed, waste plastics can be made into plastics again, used to produce fuel for factories, and used to generate electricity for power plants. Crushing waste plastics is a key step in managing various waste plastics. It helps to reduce the space required to store large pieces of waste plastics and reduces transportation costs. Smaller plastic particles are conducive to further waste plastic management.
The plastic granulator developed is widely used in the shredding process of plastic recycling processes.
Aplicación: Various types of plastics, such as electronic waste plastics, domestic waste plastics, industrial waste plastics, automobile waste plastics, etc.
Outlet size: ≤30mm\ ≤50mm\ ≤70mm\ ≤100mm
Capacity: 2-20 tons per hour
According to different material processing and different industry needs, there are corresponding parameter configurations for torque, speed, action program, and knife configuration to ensure. The final discharge meets the subsequent resource processing process requirements of various industries.
