What are the challenges of recycling plastic waste?

Plastic waste is a common waste in daily life. Data show that the recycling rate of plastic waste is less than 10% globally, while landfill and incineration account for more than 70%, which poses a challenge to the ecological environment. Surveys show that plastic waste pyrolysis projects urgently need to solve a series of practical problems.

Plastic waste pyrolysis technology

For plastic waste pyrolysis projects, the biggest technical difficulties are that the actual amount of plastic feed is lower than the capacity claimed by the pyrolysis plant suppliers, and the problem of paraffin during the pyrolysis process leading to the blockage of the oil and gas outlet and condensate pipe. However, for these two very difficult problems that are common in the market at present, DOING, as one of the top suppliers of pyrolysis plant, has successfully solved them.

1. Actual capacity lower than the claimed capacity

Conventional raw materials for pyrolysis plants are tires, plastics, sludge, rubber and so on. Unlike tires, plastic is more fluffy and loose, so if the conventional feeding method is used, it will not be able to reach the full load of feed.

Plastic waste pyrolysis machine process

For this situation, the pyrolysis reactor provided by DOING adopts the design of two ends with oval head, and the reactor size of 15 tons of processing capacity is 2800*8800mm. According to the calculation of volume and density, it is no problem to reach full load. In addition, DOING can provide hydraulic feeders and screw feeders to speed up the feeding efficiency, which can be selected according to different plastics and different states of customers.

2. Problems with wax during pyrolysis

Because there are many types of plastics, in the pyrolysis process, there will inevitably be paraffin problems, especially PE plastics. For the problem of plastic paraffin, DOING provides two solutions, one is the use of catalysts, the other is the use of special structures at the air outlet. According to the feedback of domestic and foreign customers, these two solutions can solve the problem of paraffin wax. Customers can choose according to actual needs.
