Refuse Derived Fuel

A type of Waste Derived Fuel, Refuse Derived Fuel or RDF has been prepared by a treatment process to produce a broad specification fuel, which is still considered to be a waste, that can be used by an EfW plant supplied under a Fuel Supply Agreement. The specification will depend upon the plant to be used, but typically at the most basic level will have had metals and inert materials removed, removal of some recyclables and limited shredding/bag splitting. More refined RDF will have had drying, shredding to a uniform size and Moisture Content reduction. At the very high end of production the RDF will move towards being a Solid Recovered Fuel (SRF).

Context

A type of Waste Derived Fuel, Refuse Derived Fuel or RDF has been prepared by a treatment process to produce a broad specification fuel, which is still considered to be a waste, that can be used by an EfW plant supplied under a Fuel Supply Agreement. The specification will depend upon the plant to be used, but typically at the most basic level will have had metals and inert materials removed, removal of some recyclables and limited shredding/bag splitting. More refined RDF will have had drying, shredding to a uniform size and Moisture Content reduction. At the very high end of production the RDF will move towards being a Solid Recovered Fuel (SRF).

Composition of Refuse Derived Fuel

We have pulled together a number of specification (spec) sheets to produce give an overall feel for the spec of Refuse Derived Fuel and Solid Recovered Fuel, as shown in the table below. In reality the spec is usually very tightly controlled by the receiving plant.

Measure	Units	Residual Waste	RDF	SRF
Net Calorific Value	MJ/kg (as received)	9 - 15	10 - 15	>18.5
Moisture	wt% (dry basis)	10 - 40	<20	<15
Biomass Content	wt% (dry basis)	>45	>65	>65

Background to Export of Refuse Derived Fuel

The movement of RDF from the UK, primarily in the EU, commenced in c.2010 and progressively grew up until around 2016 driven by supply-demand and landfill tax in the UK and the economics and spare capacity of EfW plants in the EU. From around 2017 tonnages for export started to drop, with more pronounced drops from 2018 as the supply-demand patterns changed in the UK, some EU countries started to implement taxation on EfW and the cost and complexities of transportation following Brexit increased. The two charts below show the overall patterns of export:

CIWM Presidential Report (2018) Showing Grow in RDF and SRF Export	Analysis by Monksleigh of RDF and SRF Exports from England from EA Data

Moving Refuse Derived Fuel and Solid Recovered Fuel from the UK abroad requires compliance with the Transfrontier Shipment Regulations (TFS) and in simple terms requires an application for movement to be made to the relevant authorities that requires a number of key measures to be satisfied before this can occur.

Annual Export from England

The data shown is for export from England and for Waste Code 19 12 10 - combustible waste (refuse derived fuel) as this is the primary code that covers both RDF and SRF tonnage.

It is important to note that some RDF / SRF is exported under the Waste Code 19 12 12 - other wastes (including mixtures of materials) from mechanical treatment of wastes other than those mentioned in 19 12 11, this code is a catch all, and covers any waste from Mechanical treatment not covered by it's own 19 12 waste code and as such has not been included in the numbers below.

Month on Month Export

The graph shows the monthly shipments of RDF along with a trend line showing the trajectory of export.
