Pyrolysis equipment is one of the better ways to treat municipal solid waste. Municipal solid waste pyrolysis is carried out in an oxygen-deficient environment, making the waste have resource and energy recovery value. Solid waste pyrolysis equipment not only reduces environmental pollution, but also maximizes resource utilization.
Municipal Solid Waste Pyrolysis Project
Municipal solid waste can be disposed of in a variety of ways, such as landfill, composting, recycling, incineration, pyrolysis and gasification. Studies have shown that energy recovery from municipal solid waste is economically feasible and sustainable. Various forms of energy can be recovered, such as heat, electricity or fuel.
Pyrolysis technology for municipal solid waste is considered an alternative to traditional incineration and landfilling, and it has the potential to recover resources and reduce environmental pollution.
As a professional pyrolysis plant manufacturer, Mingjie Group offers pyrolysis solutions for different types of solid waste. Please tell us the project you want to handle, and we will recommend you the suitable pyrolysis equipment.
Principles of Municipal Solid Waste Pyrolysis
Pyrolysis of municipal solid waste is the process of decomposing organic matter into small molecular compounds by heating (300°C-800°C) in an oxygen-free or oxygen-limited environment. Organic components in municipal solid waste (such as plastics, paper, and food residues) undergo chemical bond breakage during pyrolysis.
Main products of MSW pyrolysis
- Pyrolysis oil (Fuel Oil): A liquid product similar to crude oil that can be used as fuel or further refined.
- Pyrolysis char (Carbon Black): A solid residue, mainly carbon, which can be used as a soil conditioner, adsorbent, or fuel.
- Pyrolysis gas (Syngas): Combustible gases such as hydrogen (H₂), carbon monoxide (CO), and methane (CH₄), which can be used for power generation or as a chemical raw material.

How Does MSW Pyrolysis Plants Work?
- Municipal solid waste pretreatment: MSW is sorted, crushed and dried. During this process, inorganic matter (such as metals, glass) and moisture are removed to improve the efficiency of pyrolysis.
- Pyrolysis reactor: The pretreated waste is sent to the MSW pyrolysis reactor and heated under oxygen-free or oxygen-limited conditions.
- Product separation and collection: The MSW pyrolysis gas is separated into pyrolysis oil through a condensation system, and the remaining gas can be used for energy recovery after purification. Pyrolysis char is discharged from the bottom of the reactor and collected after cooling.
- Gas purification and emission control: A small amount of harmful gases (such as HCl, SO₂) may be produced during the pyrolysis process. These gases need to be treated by a purification system to ensure that the emissions meet environmental standards.
