Waste-Derived Fuel Briquette Machines

Global waste generation is climbing fast. Landfills are overflowing, and incineration alone creates its own environmental headaches. The smarter path? Turn the combustible fraction of waste into a solid fuel.

That’s where waste‑derived fuel (RDF/SRF) briquetting comes in. The process starts with sorting, shredding, and separating materials like municipal solid waste (MSW), industrial sludge, textile scraps, and plastics. Then a high‑pressure briquetting machine compacts those fractions into dense, uniform briquettes. The result: a solid fuel with a calorific value of 3,000–6,000 kcal/kg—comparable to coal, but made from waste.

RDF briquetting machine can briquette industrial waste (leftovers from clothing factories, unloading machines from shoe factories, dust bags from factory buildings, waste plastics from paper mills, domestic waste, etc.). The pressed products are mainly used to supply power plants for burning. The pressed products not only perfectly solve the storage and transportation problems of these wastes, but also can be comprehensively reused.

Municipal solid waste (MSW)briquetting machine is a kind of equipment specially used to press municipal solid waste into briquettes. The pressed products are mainly used to supply power plants for combustion. The pressed products not only perfectly solve the storage and transportation problems of these wastes, but also can be reused comprehensively. These briquettes can be used as a fuel source or other purposes, helping to reduce the amount of waste and promote recycling.

An industrial sludge briquetting machine is a machine that forms industrial waste sludge into briquettes. Sludge briquetting machines are used to compress or briquette waste materials, including sludge, into a solid, compact and more useful form. These briquettes can be used as fuel for boilers, stoves and other applications that require fuel. The machine compresses the sludge under high pressure and temperature, causing it to bind together.

First, the waste material is crushed to a length of 30–60 mm, with a moisture content of 15%–25%. The crushed material is then fed into the briquetting machine by a feeding conveyor, which evenly distributes it into the working area between the press rollers and the flat die. As the main shaft rotates, it drives the press rollers, forcing the material to be extruded through the flat die to form briquettes, which finally fall from the discharge port.

The briquetting machine can compress various types of industrial waste — such as offcuts from garment factories, trimming waste from shoe factories, dust collector bags from workshops, waste plastics from paper mills, and household garbage — into dense briquettes. These briquettes are primarily used as fuel for power plants. By compacting the waste, the machine not only solves the problems of storage and transportation but also enables comprehensive recycling, turning waste into valuable resources.
