Refuse-Derived Fuel (RDF)
Refuse-Derived Fuels, or RDF, are solid, liquid or gaseous fuels generated from the recovery of hazardous, non-hazardous or inert waste. RDFs are a way of obtaining energy in a way that reduces Urban Solid Waste giving it a new life. It is one of the sources most used by most countries in recent years.
Its valorisation process is as follows:
- First, they shred the MSW to reduce its size.
- Secondly, the waste passes through a magnetic separator that separates the rejected metals from the waste that is accepted.
- Thirdly, the well separated waste is screened to homogenize the size and facilitate its later combustion.
- Finally, the material resulting from the screening is granulated to make it finally fit the desired size.
RDFs are an energy source comparable to coal or gas obtained through energy recovery.
