Can construction waste be recycled by pyrolysis machine?

Construction waste refers to waste and debris generated during construction, demolition, decoration or maintenance, which typically consists of a mixture of materials, including concrete, bricks, wood, metals, waste plastics and rubbers. For the waste plastics and rubbers can be recycled with the pyrolysis machine, so in recent years, pyrolysis machines have become a popular choice for recycling construction waste.

Construction waste for pyrolysis machine

The following is a brief introduction about how to recycle construction waste with the pyrolysis machine(take DOING construction waste pyrolysis machine as an example):

1. Preprocess: For the complicated components of the construction waste, we need to sort the plastic and rubber products by machines and manual labor, such as various cable skins and plastic products in the construction waste, whose oil yields can reach about 60%; Then, we need to separate the metals, glass, sand and other materials by magnetic separation, because these raw materials not only cannot be pyrolyzed to produce oil, but their presence will also cause wear and tear on the pyrolysis machine, affecting the quality of pyrolysis oil and carbon black products.( Generally, the plastic and rubber need to be recycled with the pyrolysis machine separately.)

2. Heat and Pyrolysis: Feed the separated materials into the pyrolysis machine and heat the reactor to a certain temperature, then the raw material will be pyrolyzed into oil gas;

3. Cooling: After the oil gas comes out, it goes through the cooling system, then the oil gas will be cooled into liquid pyrolysis oil and stored in the oil tank;

4. Product Collection: Commonly, the final products are pyrolysis oil, carbon black and syn-gas, which all have various applications to generate huge profits;

Pyrolysis oil can be used as fuel energy in cement plant, steel plant, glass plant, heavy oil machinery, generator or be refined into diesel oil with the pyrolysis oil distillation plant; carbon black can be used as fillers, soil amendments or to make new rubber products; syn-gas can be used as fuel to power the plant or further processed;

Applications for obtained pyrolysis oil

Additionally, DOING pyrolysis machines also have great environmental benefits by recycling construction waste. During the whole process, there won't produce any pollution: for waste water, DOING pyrolysis machine adopts the circulating water to cool the oil gas, which has no waste water pollution; for exhaust gas, DOING equips the tail-gas cleaning system and desulfurization tower to make further purification for the exhaust gas, which can meet the emission standards in various regions, truly achieving double benefits of environmental protection and profits.
