Foreword
This document (CEN/TR 13768:2004) has been prepared by Technical Committee CEN /TC 308, "Characterization
of sludges", the secretariat of which is held by AFNOR.
This document supersedes CR 13768:2001.
Significant technical differences between this edition and CR 13768:2001 is taking account of the new Directive
2000/76/EC (incineration of waste).
The status of this document as CEN Technical Report has been chosen because the most of its content is not
completely in line with practice and regulation in each member state. This document gives recommendations for a
good practice concerning the combined incineration of sludges and household wastes but existing national
regulations remain in force.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Report: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
Introduction
All of the recommendations of this document constitute a framework within which the combined incineration
process can be proposed in addition to and/or as a substitution for field spreading, waste site disposal (landfilling),
specific incineration (see TR 13767), or any other process.
Combined incineration should abide by the European Directive 2000/76/EC (Incineration of waste) and should
comply with the relevant regulations and recommendations in force within each member state to reduce as far as
possible negative effects on the environment such as pollution of the air, ground, surface and underground water,
and on human and animal health. This concern therefore relates to: the pre-treatment of the sludge in plants, the
transfer of the material to the treatment centre, the actual destruction process, the treatment of gaseous discharge
into the atmosphere, the future of the different by-products stemming from combustion and the treatment of the
liquid effluents possibly resulting from the process.
Anyway, priority should be given to reduction of pollutants at the origin and or to recovery of valuable substances
(phosphorus, potassium…) in sludge and derived products if technically and economically feasible.
As part of a process and company quality approach, the relevant issues are therefore :
exploiting the operating data and the statutory inspections carried out ;
rendering the process reliable, optimising and of perpetuating it, as well as guaranteeing a permanent
development ;
maintaining a climate of confidence between the authorities, the sludge producers, the transporters, the
incineration plant and waste disposal site operators and to allow the services to be provided on a contractual
basis.
When necessary, a distinction can be made between existing facilities and new incineration plants.

regard to their discharge into the atmosphere

waste disposal site for the deposit of the waste onto or into land

[see EN 13965-2]
4 Requirements
4.1 General
As a general rule, the criteria, which lead the decision-makers to choose combined incineration, are similar to those
which lead them to construct or to extend incineration plants for household waste only.
The local recommendations take into account :
impossibility to introduce or pursue any other process or to have at one's disposal an alternative to existing
solutions, throughout whole or part of the year, in particular in the case of technical shutdown and particularly if
the incineration plant only has one treatment unit ;
geographical context, the client population and therefore the potential input material (waste + sludge) as well
as the expected developments ;
proximity of the sewage treatment plant/incineration plant and the local road network ;
extent to which the incineration plants are used (dimensioning of furnaces, charge levels, filling) ;
va
