RDF(Refuse Derived Fuel) is a fuel that is normally produced from waste with high calorific value. It is used as fractions of high heating value for substitute scarce and expensive fossil fuels and becoming more popular. The original waste comes from households, bulky waste, industry and commerce and is processed for energy extraction.It is meant for co-incineration plants and replaces standard fuels (e.g. coal) in production plants for cement, power plants or other co-incineration plants.

In order to produce refuse derived fuels with defined qualities and guaranteed specifications, multi-level processing is required that mainly includes the following stages:

  1. Primary shredding
  2. Separation of ferrous metal and non-ferrous metal
  3. Separation of extraneous material (by e.g. air-steam or ballistic separators)
  4. Secondary shredding
  5. Pelleting(briquetting)

Processing of RDF usually takes place in the following RDF value categories:

  • low calorific RDF
  • average calorific RDF
  • high calorific RDF
