How to produce RDF(refused derived fuel) from plastic scrap?

To produce RDF(refused derived fuel) from plastic scrap, we need one machine: waste plastic recycling pyrolysis machine, which can recycle plastic scrap to RDF and other useful final products in an environmentally friendly method.

Here this passage will have a brief introduction about the work process to produce RDF from plastic scrap with the waste plastic recycling pyrolysis machine:

1. Pre-processing: Collect and sort plastic scrap according to the type (e.g., PS, ABS, Aluminum plastic, HDPE, PP, etc.) to ensure homogeneous feedstock for optimal pyrolysis efficiency. Remove contaminants such as metals, glass, and other non-plastic materials, as they can interfere with the pyrolysis process or damage the waste plastic recycling pyrolysis machine.

2. Feeding the Pyrolysis Reactor: Transfer the prepared plastic scrap into the pyrolysis reactor, here to enhance the feeding efficiency, we can equip the waste plastic recycling pyrolysis machine with the auto-feeder.

3. Heating and Pyrolysis: Heat the reactor to the desired temperature, typically ranging from 350°C to 700°C, depending on the type of plastic and the desired end product. Under these conditions, the plastic undergoes thermal decomposition, breaking down into smaller molecules without oxygen present.

4. Cooling and products collecting: After the plastic scrap was pyrolyzed into smaller oil gas molecules, the oil gas will pass through the cooling system to cool down into liquid RDF. And in addition to the RDF, we can also get other useful products, such as carbon black and combustible gas;

5. Retention Time and Temperature Control: Maintain the appropriate retention time (typically several hours) and temperature profile within the reactor to optimize the yield and quality of the RDF. Adjust these parameters based on the specific plastic types and the desired RDF characteristics.

The obtained RDF from plastic scrap with the waste plastic recycling pyrolysis machine can be collected, cooled, and filtered to remove impurities. Depending on its composition and intended use, it may require further refining or blending with other fuels. RDF can be used as a substitute for fossil fuels in industrial boilers, power generation, heavy oil industries(like steel factories, glass factories, brick factories, etc.) or as a feedstock for chemical production.
