2 Overview of presentation
ERFO Definition of SRF Examples of production and use Environmental/ energy topics Conclusions

3 European Recovered Fuel Organisation A non profit association Purpose
ERFO European Recovered Fuel Organisation A non profit association Purpose Represent European companies which produce fuels prepared from non-hazardous waste Promote the use of such recovered fuels within the frame of sustainable development Help establish high quality standards for such fuels at European level

4 ERFO’s Focus on standards
Recovered fuels must gain public acceptance, trust and confidence Public trust is only possible if the conditions for preparation, transport and use of recovered fuels are stringent, transparent and easily controllable Standardisation is a must Solid Recovered Fuels (SRF)

5 ERFO’S INVOLVEMENT SRF standardisation work within CEN / TC 343 e.g. report on classification of SRF Participation in R&D programs Pre-normative research on sampling, sample preparation and determination of biomass content QUOVADIS : validation of Technical Specifications, Quality Management system and perspectives in new EU countries Participation in debates, works and lobbying activities related to SRFs Main contribution to the SRF chapter of the Bref Waste Treatment

SRF must be distinguished from other waste derived fuels; declaration of conformity should be a minimum requirement SRF should be qualified as as specific (non hazardous) entry on the European Waste Catalog as as specific entry on the green list of waste SRF name / qualification should be protected

7 Definition of SRF Solid fuel prepared from non-hazardous waste, meeting the classification and specification requirements of prCEN15359 Prepared means processed, homogenised and up-graded to a quality that can be traded amongst producers and users

8 Examples of production plants
Paper/plastic fraction: Essent Milieu, VAGRON Groningen Solid recovered fuel (SRF): Veolia, Haraldrud Oslo Remondis, VZEK Erftstadt


10 Production location VAGRON (Groningen)
Screening drums separate the waste. Air classifiers separate a paper/ plastic fraction.

Dans ce cas le déchet subit une préparation plus rudimentaire (broyage grossier). Il faut aussi mentionner la production de RDF à Dade County (Miami, USA) par Montenay Power Corp., filiale d’Onyx North America Final SRF (fluff) 50mm Over band magnet Optional 1st SRF (fluff) 50mm Final SRF (baled) Fine shredder Baler

16 Quality control Currently: ISO 9001:2000
Based on operator experience for pre-sorting of unsuitable material. On-site laboratory with adapted sampling and sample reduction procedure (pre-normative research project - TAUW/NOVEM/ERFO download ). Additional chemical and physical properties analysis carried out externally. Under progress : Implementation of a QMS based on future CEN standards (QUOVADIS project).

BImSchV (WID) landfilling characteristics of combustion residues RWE Power setzt heute sechs deutschen Kohlekraftwerken an den Standorten Westfalen, Werne, Ibbenbüren, Frimmersdorf, Weisweiler, Wachberg und Berrenrath Ersatzbrennstoffe in der Form von Klärschlamm, Papierschlamm sowie andere Ersatzbrennstoffe bestehend aus Tiermehl, Altholz und sogenanntem SBS (Sekundärbrennstoff = heizwertreiche und schadstoffarme aus Siedlungsabfällen in zertifizierten Aufbereitungsanlagen gewonnene Brennstoffe) ein. Entsprechend der vorliegenden Verträge mit RWE Umwelt und anderen Entsorgungsunternehmen oder Lieferanten sowie der Verfügbarkeit dieser Stoffe am Markt konnten wir die zur Verfügung stehende Kapazität bisher zu rund 65 % - d.h. mit rund 1,2 Mio. jato - auslasten. Die umweltfreundliche Mitverbrennung von Schlämmen und anderen Ersatzbrennstoffen reduziert die benötigte Menge an Regelbrennstoffen zur Stromerzeugung und entlastet gleichzeitig die Deponien. Damit leistet RWE einen wichtigen Beitrag zur ökologisch verträglichen und energetisch sinnvollen Verwertung dieser Reststoffe.
