Is pyrolysis better than incineration?

The decision on whether pyrolysis or incineration is better depends on various factors, including the energy efficiency, environmental impact, and whether they're sustainable. In this article, we delve into the differences between pyrolysis and incineration and how they perform in the above three aspects.

First, let's learn the difference between pyrolysis and incineration.

Pyrolysis VS Incineration

1. Different principles: Pyrolysis is a thermal decomposition process that decomposes long-chain molecules at high temperatures in an oxygen environment to produce light products. While incineration is a combustion process that burns waste into ash and gas in an aerobic environment.

2. Different application fields: Pyrolysis is mainly used in the petrochemical industry to get energy, while incineration is mainly used in the environmental protection industry and municipal waste treatment, and may get no energy. Normally, if you want to recycle tires, plastic or oil sludge to get energy, you can consider pyrolysis. If you just want to dispose of waste and have no need for energy, then incineration you can consider it.

In our daily life, most customers prefer pyrolysis to incineration. Pyrolysis can get energy and make a huge profit. Next, why do most people prefer pyrolysis? That is, why is pyrolysis better than incineration?

1. Energy Efficiency

In terms of energy efficiency, pyrolysis is better than incineration. While both processes generate energy, pyrolysis has the added advantage of producing valuable by-products such as fuel oil, carbon black and syngas.

1). The fuel oil can be an alternative fuel to petroleum, used as heating fuel in many industrial plants, such as steel plants, cement plants, power plants, etc. Or it can be converted into diesel through pyrolysis oil refining machine for use in diesel engines.

2). The carbon black through deep processing can be used as a raw material for rubber products, an alternative fuel for coal, a raw material for lithium batteries, a raw material for pigments, etc..

3). The syngas methane element and can be burned directly as fuel. For example, it can be used as a raw material for pyrolysis heating, reducing the cost of burning raw materials.

2. Environmental Impact

One of the significant advantages of pyrolysis over incineration is its minimal environmental impact. DOING pyrolysis plants are equipped with gas treatment systems, which can remove harmful gases such as hydrogen sulfide gas to ensure no pollution before emission. Moreover, the absence of oxygen in the pyrolysis process prevents the formation of harmful pollutants that are commonly associated with incineration.

3. Sustainable Development

Incineration, while effective in reducing waste volume, is often considered less desirable due to its potential negative impacts on the environment and public health. Pyrolysis offers a more sustainable and responsible approach by converting waste into useful products without compromising the ecosystem.

Through the above comparison, it is found that pyrolysis does perform better than incineration in many aspects.
