Diesel oil is a light petroleum product and a complex hydrocarbon mixture. When used as fuel, it is mainly applied in diesel engines of vehicles and ships, and is an important energy resource. Plastic, as one of the most common living materials, is widely used in daily life and industrial production. At the same time, however, the problem of “white pollution” caused by plastics wastes also has been bothering us. China produces more than 60 million tons of plastics wastes every year., while globally, this figure exceeds 300 million tons, making plastics waste the type of solid waste with the highest output in the world, however only less than 30% of it is recycled.

If the plastics waste products can be converted into diesel fuel, an important energy source, that definitely would be uplifting.

This is not nonsense. The pyrolysis technology and solutions provided by Niutech Environment Technology Corporation are realizing this great transformation, “converting waste into treasure”.

“Chemical recycling” of plastics waste

First of all, we need to understand a concept-“chemical recycling”. Chemical recycling of plastics wastes is also called “advanced recycling”. Chemical recycling refers to a plastic recycling method that uses chemical means to turn plastics wastes into useful components and can be roughly divided into two forms: pyrolysis and depolymerization into monomers.

The process of producing diesel oil by pyrolysis of plastics wastes falls into the category of chemical recycling of plastics wastes.

Because plastics waste products are difficult to degrade naturally, when adopting physical recycling method, it is only focused on those plastics waste with high value.; meanwhile, chemical recycling can not only deal with plastics wastes of single component, but also can process plastics waste with complex components and therefore difficult to separate that cannot be treated by traditional physical recycling, or plastics waste that bear low performance and value after physical recycling.

Therefore, the chemical recycling of plastics wastes is an advanced technology path to solve the pollution problem of plastics wastes and realize the recycling of it.

Niutech Environment Technology Corporation: producing diesel oil by pyrolysis of plastics waste

Generally, pyrolysis technologies are adopted in the production of diesel oil using plastics waste as raw material, that is, according to the thermal instability of plastics and other organic matters, under the oxygen-free or oxygen-poor environment and certain temperature, through the co-effects of condensation and decomposition, macromolecular organic matters are transformed into gaseous, liquid and solid components with relatively small molecular weight, among which the liquid product is “pyrolysis oil”, which can be made into diesel oil after further processing.

The industrial continuous plastics waste pyrolysis production line independently researched and developed by Niutech, is capable of thoroughly decomposing PP, PE, PS and other single or mixed plastics to produce fuel oil, solid fuel and non-condensable combustible gas. On the premise of safety, environmental protection, continuous and stable operation, the plastics wastes can be recycled, bio-safely disposed and reduced.

This set of pyrolysis technology and equipment can achieve a pyrolysis rate of more than 99%, and realize resource recovery and recycling to the greatest extent.

With low cost, high degree of recycling and good environmental benefits, pyrolysis technology has become the mainstream non-hazardous and bio-safety treatment and resource utilization technology of organic wastes at home and abroad.

Niutech’s pyrolysis technology for the treatment of plastics waste and application cases

Niutech’s pyrolysis solutions for the treatment of plastics waste have been successfully applied to many projects at home and abroad, among which the plastics waste disposal project in Denmark has been invested and recognized by BASF, the global chemical giant.

Producing diesel oil from plastics wastes by pyrolysis and turning waste into energy products can not only solve the white pollution problem that bothers us, but also realize the resource utilization of waste pollutants, create well-performing economic benefits, and continuously make rational and lasting use of plastics waste as resources, which is a great benefit for mankind and the whole world, and is a plastics waste treatment technology and solution worthy of wide popularization.
