Conclusions: benefits of SRF in the European context
1) SRF (Solid Recovered Fuel) : definition
The Landfill Directive requires diversion of
biodegradable waste from landfill. Some
member States have already implemented a
“ban” for combustible waste or “organic
waste” in landfill.
Other recovery options for mixed
combustible waste are limited. Direct
incineration plants are well suited for large
cities but their permitting procedure is
difficult and time consuming.
SRF
SRF is a solid fuel prepared from non-hazardous waste, meeting the classification and
specification requirements of CEN-TS15359.
The SRF is processed, homogenised and up-graded to a quality that can be traded amongst
producers and users.
SRF is a tradable and storable fuel that, depending on quality, can be used with a high
electricity efficiency.
The use of SRF saves other resources, it contributes to the EU strategy “Security of Energy
Supply” and helps achieve the Kyoto targets in terms of avoided CO2 emissions.
1) SRF: drivers*
INDUSTRY ISSUES
DRIVERS
SOLUTION PROVIDED BY SRF
Diversion biomass
MSW, with its biomass content, is
not disposed in landfill, but
recovered as energy
Renewable Energy
Sources (RES) Directive
Biomass content
Energy production through SRF
co-firing contributes to reach the
Directive targets
Best Available Practice
Energy/climate change
(Emission Trading
Directive)
1 ton of SRF (through its
production from MSW and its cofiring ) reduces emissions of CO2
by not less than 1 ton CO2 **
Oil/gas/coal, CO2
SRF has the lowest production
cost amongst RES and
lowers electricity production costs

** Average value of CO2 saving, to be validated case by case by applying the specific methodology set by CEN. In Italy
tests on significative samples, certified by external body (Stazione Sperimentale Combustibili) , showed a reduction of
1,75 tonCO2 for 1 ton of SRF.
2) SRF: composition and uses
Derived from
 dry fraction from Municipal
Solid Waste (MSW)
 chlorine-free plastic waste
and rubber
In order to deliver
Solid Recovered Fuel
(SRF)
 dry fraction from Industrial
waste
 high and constant quality
(High Quality SRF)
 calorific value close to coal levels
(more than 5.000 kcal/kg,
i.e. 22.000 kjoule/kg)
SRF potential uses
DIRECT USE
 COAL
 PETCOKE
 LIGNITE
Using in conjunction with coal and
petcoke in:
 Coalfired power plants (10%)
 Cement kilns (over 40%)
 CHP ind. Boilers (12%)
Uses of
SRF
 COAL
VIA GASIFICATION
 GAS
 ORIMULSION
Using in conjunction as syn-gas
in power plants (10%)
3) REQUIREMENTS OF INDUSTRIAL USERS OF SRF:
Need for standardization of SRF
At present recovered fuels are still considered wastes, under the
European laws and in the majority of European countries.
In order to simplify trade, standardized SRF should be at least qualified
for the notification’s procedure of the Basel ”green list”. Although the
costs for re-permitting under the Waste Incineration Directive (WID)
are moderate, combustion plants do not want to be labelled as “waste
incinerators”.
The present proposal for the revision of the Waste Framework Directive
(WFD) and a proposal for a European Biomass Action Plan (BAP)
include elements by which “the use of waste as a fuel may be made
easier”.
European standards for the clustering of SRF may be used to tackle this
important issue.
3) REQUIREMENTS OF INDUSTRIAL USERS OF SRF:
Future work of CEN/TC 343
The technical specifications (TSs) proposed by CEN/TC 343 were
approved by unanimous vote and were published in 2006.
TSs validation is under way in the EU funded project QUOVADIS. A
third dissemination workshop was organized in June 2006. First results
will be available by end 2006.
Once validated, TSs will be subject to public enquiry which will put
TC343 in the position to upgrade and finalize the European Norm (EN).
The upgrading will take 1 to 3 years, depending on the outcome of the
public enquiry (and the status of the Waste Framework Directive-WFD
and Biomass Action Plan-BAP).
4) EUROPEAN OVERVIEW: SRF market potential
By assuming a 10% substitution rate in power plants, SRF market
potential (*) in EU15 amounts to 57 mio t/y, with:
avoided CO2 up 100 mio t/y
a saving of fossil fuels
around 30 Mtep/y
a turnover of around 14 billion € per year.
* The potential market value has been calculated considering:
- a gate fee equal to 100 €/ton MSW, that is roughly equivalent to a gate fee of 200 €/ton SRF
- a SRF price equal to 20 €/ton SRF for cement kilns and CHP, and 60 €/ton SRF for power plants

4) EUROPEAN OVERVIEW: SRF current production*
Data on current production and use show that SRF has been, so far, not extensively
exploited as an option for MSW management. In particular, SRF use has so far been
quite limited in power plants given the lack of market power of Low Quality SRF.

5) EUROPEAN OVERVIEW: ITALY
HQ-SRF under the Italian Legislation
 SRF for standard use in dedicated plant is classified as special waste
 The HQ-SRF, utilized in co-firing in power plants and cement kilns, is classified
as fuel
 In proportion to its fraction of biomass, SRF is also a renewable energy source
(RES)
 SRF and HQ-SRF benefit of the Italian incentives schemes designed for electricity
produced from RES

- A proposed European Norm for the standardization of SRF is expected to be edited soon by CEN (Comité Européen de Normalisation) for a validation program.
- The proposal - that will be published as Technical Specification (TS) is the result of the activity of a specific technical committee (CEN-TC343) appointed by the
European Commission for the purpose.
- During the validation time (three years) and until the final approval of the European Norm (EN) each member state can apply its national standard
d) ITALY: SRF Market potential
Nothwithstanding limited coal usage in Italy, the potential of the HQ-SRF’s utilisation in
existing plants (cement kilns and power plants) could allow to recover up to 10 milion tons of
MSW (50% of MSW currently disposed of in landfill).

The co-firing of HQ-SRF could also allow:
 avoidance of the emission of about 9,2 Million Tons of CO2 per year (about 10% of the
“Kyoto Protocol” targets)
 production of electricity from Renewable Energy Sources for about 5 TWh/year (23% of
the gap remaining to reach the objective under Directive 2001/77/CE)
d) ITALY: some experiences
• Cement kiln, Buzzi-Unicem (Cuneo)
- 2 Mt/a clinker
- 40 kt/a* SRF substitution rate 20%
20 kt/a of HQ-SRF, with the full recovery of MSW locally produced
20 kt/a of SRF from commercial/industrial waste
• Hard coal, Enel Fusina (Venezia), group 3 = 320 Mwe,
- 35 kt/a** of SRF, with a partial recovery of MSW locally produced
•With a potential quantity of other 70 kt/a, subject to autorizhation
•** Group 4 is available for an equivalent amount, subject to autorizhation

6) THE FUTURE SRF UNDER A
EUROPEAN PERSPECTIVE
The Thematic Strategy aims, inter alia, at:
 promoting recovery of waste
 increasing the resource efficiency
 reducing the negative environmental impact of use of natural resources
 developing common reference standard for recycling and recovery
moving towards a recycling and recovery society (i.e. moving up the
hierarchy, away from landfill and more and more to recycling and recovery
 introducing a life-cycle thinking into waste policy
6) THE FUTURE SRF UNDER A
EUROPEAN PERSPECTIVE
SRF

is the result of a recovery process

complies with standards (national and European, when available) and aims
at reducing the environmental impacts both of waste cycle and industrial
plants that use it

is a product usable, with economic value, only and exclusively if compliant
with standards and used in certain industrial plants

is produced and used in compliance with applicable legislation (e.g.
WID/IPPC)

substitutes natural resources (fossil fuels)

LCA is positive
SRF complies with Thematic Strategy
7) CONCLUSIONS:
In the European arena, the use of SRF allows benefits like:
 Achieving goals of the Thematic Strategy
 Saving of natural resources / substitution of fossil fuel
 Compliance with ECJ rulings
 Achieving targets of the Kyoto Protocol (avoiding CO2 emissions) and of
European Renewable Energies’ legislation (due to biogenic content of SRF)
 Achieving recycling and reduction targets for biodegradable materials
going to landfill
Since mid 2006 Tecnhical Specifications (TSs) are available to describe SRF
under a technical profile.
It is high time for a European common policy in order to provide
each Member State with a common “level playing field”.
