What is the difference between pyrolysis and incineration for waste plastic treatment?

Pyrolysis and incineration are two ways of disposing waste plastics. The main difference lies in that the pyrolysis will not cause pollution to the environment and the recycling of resources can be realized. However, direct incineration of waste plastics will seriously pollute the environment and waste resources.

Direct incineration of waste plastics

Waste plastics are now treated by pyrolysis rather than incineration. Next, I will make a simple analysis of the difference between pyrolysis and incineration.

Pyrolysis is a reaction process of waste plastics under high temperature hypoxia or hypoxia conditions. Through pyrolysis, waste plastics will be converted into combustible gas mixture, pyrolysis oil, carbon black and so on.

Incineration is in the case of sufficient oxygen, so that waste plastic oxidation, heat generation, but also there will be a large number of dioxins, fly ash, nitrogen oxide emissions.

All these emissions will pollute the environment.Pyrolysis and incineration have the same effect on waste plastics, and the final treatment results can make the heat value of waste plastics disappear to zero, and the residue is basically completely inorganic.

Waste plastics are treated by pyrolysis

Through the in-depth study of pyrolysis and incineration of waste plastics, the plastic pyrolysis equipment produced by DOING company with pyrolysis technology has very good environmental protection, and simple operation, can batch processing of waste plastics, not only improve the efficiency of waste plastics processing, but also greatly save manpower and time.

Plastic pyrolysis equipment

Pyrolysis oil and carbon black can be obtained by treating waste plastics with plastic pyrolysis equipment. Both pyrolysis oil and carbon black can be used in industry, giving full play to their value again and realizing the recycling of resources. Direct incineration of waste plastics, however, produces heat that is difficult to collect and reuse, and most of it is wasted.

Given the difference between pyrolysis and incineration above, which one do you choose when dealing with waste plastics?
