Turning RDF/SRF to Power Safely
Conventional RDF/SRF production technology is used to recover the drier higher calorific fraction of municipal solid waste (MSW). This is then pelletised to form a consistent pyrolyser feedstock which is then metered into the M3RP pyrolysis retort (sealed chamber) through airlocks.
Inside the retort the materail is indirectly heated to 600°C in the absence of oxygen, by a low NOx burner running off previously produced pyro-gas. The heating in the absence of oxygen causes the materials within the RDF/SRF to break down into their constituents, for example plastics de-polymerise into oil and gas.
The RDF/SRF denatures into syn-gas and pyro-char. The syn-gas is then condensed and some of it turns to syn-oil

The syn-gas and syn-oil can then be sent through dual-fuel generators to produce electricity, some of which can be used to run the plant and the majority exported to the national grid.
The pyro-char is conveyed through airlocks out of the base of the retort, to a carbon handling system. In the case of RDF/SRF Flock waste, the pyro-char is of sufficient quality to be sold commercially for many uses including industrial filter material or carbon black for inclusion in tyres and other products.
