What is SFR and what is it used for?

¿Qué es el CDR y para qué se utiliza?

Before delving into the usefulness of SRF (Solid Recovered Fuel) let us explain what it is:

These are solid, liquid or gaseous fuels that are produced from a range of hazardous, non-hazardous or inert wastes, and are usually destined for energy recovery in incineration or co-incineration plants.

More and more waste is generated, and most of the time, it ends up in landfill, so an improvement in waste management is necessary.

In order to reduce the amount of waste going to landfill, the concept we mentioned at the beginning was introduced: SRF (Solid Recovered Fuel). This type of sustainable energy allows the calorific potential of waste that cannot be recycled or reused to be harnessed as an alternative energy source.

At Trans Sabater we are dedicated, among other things, to the production of SRF through sustainable management of the waste we collect and receive at our management plant, and depending on its origin (although SRF is normally produced from solid urban waste) we distinguish between different production methods:

  • Pre-shredding:waste transported in containers or tippers arrives at the plant and is shredded to homogenise the waste.
  • Separation of metals: once the waste has been shredded, the metals must be separated using magnetic magnet separators.
  • Secondary shredding: the aim is to obtain a residue of between 20 and 30 mm, and for this purpose mills with blades are used.
  • Pressing: the waste is pressed to facilitate its transport.

In Spain, one of the industries that is making most use of this type of sustainable, efficient and renewable energy is the cement industry, but it is only a matter of time before more and more industries incorporate it into their production systems.
