Can waste plastic be used as fuel?

Waste plastic cannot be directly used as fuel, but it can be converted into fuel oil through the way of pyrolysis. Pyrolysis plant can convert waste plastic into fuel oil and carbon black, both of which are high quality fuel. While, the burning of waste plastic will lead to loss of valuable energy and the dumping of waste plastic is known to cause land pollution. Therefore, when it comes to plastic waste management, pyrolysis is a better alternative than incineration or dumping.

Pyrolysis vs burning vs dumping

As we all know, plastic is made from macro-molecular polymers and it is the derivatives of petroleum. Doing waste plastic pyrolysis plant is specially designed to process plastics into Heavy Fuel Oil in the absence of oxygen. In plastics pyrolysis, the macro-molecular structures of polymers are broken down into smaller molecules. Thus, producing the final product of the pyrolysis process, plastic pyrolysis oil and carbon black.

Doing waste plastic pyrolysis plant

Plastic pyrolysis oil is widely used as industrial heating fuel for cement factory, steel factory, boiler factory and brick factory, etc., due to its high heating value over 10000kcal/liter. The second by-product carbon black is a kind of solid fuel, which can be processed into briquettes and used as heating energy. Wherefore, we can see that pyrolysis of waste plastic not only has good social benefits, but also can obtain huge profits.

However, plastic has many different types and it is more complicated than tyre and rubber. Are all kinds of plastics suitable to produce fuel oil? Obviously the answer is No. For example, PET plastic like drinking water bottles can not be used as the raw material of pyroysis, because the pyrolysis of PET plastic will not produce polymer that is similar to composition of oil but main alcohols. Neither can PVC plastic, because it will release acid chlorine and cause corrosion of pyrolysis reactor.

In the end, if you are interested in the waste plastic pyrolysis plant project to get pyrolysis oil, please mention the types of plastic you want to process in your enquiry, so that we can give you professional suggestions.
