Refuse Derived Fuel

Basics

• Often abbreviated as RDF
• Fuel derived from combustible refuse
• The "Last Resort" (ie only non-recyclable material, also typically stuff that can't be Composted or Anerobically Digested )
• Also of use in Landfill Mining operations
• Used heavily in europe as they don't use landfills anymore (check if they still use them for hazardous waste, or if even that is not done (ie replaced by disposal by methods such as Pyrolysis , RTO 's , or Landfarming
• Harder to predict composition than biomass, and thus often will require Gas Scrubbing and other pollution prevention methods (granted biomass shouldhave these too, but it is even more NECCISSARY with RDF)
• From wikipedia:
  • RDF can be also further specified into e.g. tyre derived fuels (TDF) from used tyres, or solid recovered fuels (SRF)
  • (commentary/sidenote) For all intensive purposes, the distinction isn't TOO important
• Most likely not Carbon Neutral (without CSS at least), but it should still be a "net good action" for the enviroment due to landfills (or littering...)'s effect on water quality, and the local ecosystems
  • Especially if the pollutants are removed and treated properly

• Paper on The Bottom Ash / Slag (Given the gasification based slag is in "amorphous glassy phases" it should be able to be be Melt Spun into Mineral Wool / Basalt Fiber ? )
• A Company Making a Biorefinery that can Co-Fire with RDF
• "Performance analysis of RDF gasification in a two stage fluidized bed–plasma process" There is some Europe Commercial / Near Term Commercial Company using this, i think "Plasmarok" or something similar is their term for the slag in regards to reuse as aggregate etc
