RDF Plant –
Non-combustible materials such as glass and metals are removed during the post-treatment processing cycle with an air knife separation technique. The residual materials can be sold in their processed form (depending on the process treatment) or compressed into pellets, bricks, or logs and used for other purposes either stand-alone or in a recursive recycling process. RDF is extracted from municipal solid waste using a mix of mechanical and /or biological treatment methods.
The production of Refuse Derived Fuel (RDF) may invoice the following steps:
- Bag splitting/Shredding
- Size screening
- Magnetic separation
- Coarse shredding
- Refining separation
The mix of materials should be cut to particles not bigger than 25 mm / 1 inch. The moisture content of the mix should not be bigger than 15% because if so the materials will not burn well in the furnace. The particles will last between 17 to 18 seconds in the furnace, usually at 1,200 0C / 2,192 0F.
