PREFACE
1. Status of this document
Unless otherwise stated, references to the Directive in this document refer to Directive
2010/75/EU of the European Parliament and the Council on industrial emissions (integrated
pollution prevention and control) (Recast).
The original best available techniques (BAT) reference document (BREF) on Waste Treatment
was adopted by the European Commission in 2006. This document is the result of a review of
that BREF. The review commenced in June 2013.
This BAT reference document for Waste Treatment forms part of a series presenting the results
of an exchange of information between EU Member States, the industries concerned, non-
governmental organisations promoting environmental protection and the Commission, to draw
up, review, and where necessary, update BAT reference documents as required by Article 13(1)
of the Directive. This document is published by the European Commission pursuant to Article 13(6) of the Directive.
As set out in Article 13(5) of the Directive, the Commission Implementing Decision (EU)
2018/1147 on the BAT conclusions contained in Chapter 6 was adopted on 10.8.2018 and
published on 17.8.20181.
2. Participants in the information exchange
As required in Article 13(3) of the Directive, the Commission has established a forum to
promote the exchange of information, which is composed of representatives from Member
States, the industries concerned and non-governmental organisations promoting environmental
protection (Commission Decision of 16 May 2011 establishing a forum for the exchange of
information pursuant to Article 13 of the Directive 2010/75/EU on industrial emissions (2011/C
146/03), OJ C 146, 17.05.2011, p. 3).
Forum members have nominated technical experts constituting the technical working group
(TWG) that was the main source of information for drafting this document. The work of the
TWG was led by the European IPPC Bureau (of the Commission's Joint Research Centre).
3. Structure and contents of this document
General information
Chapter 1 provides general information on the waste treatment sector.
For the sake of clarity, the waste treatment sector has been divided into four chapters, each split
into several sections as shown below.

4. Information sources and the derivation of BAT
This document is based on information collected from a number of sources, in particular
through the TWG that was established specifically for the exchange of information under
Article 13 of the Directive. The information has been collated and assessed by the European
IPPC Bureau (of the Commission's Joint Research Centre) who led the work on determining
BAT, guided by the principles of technical expertise, transparency and neutrality. The work of
the TWG and all other contributors is gratefully acknowledged.
The BAT conclusions have been established through an iterative process involving the
following steps:
identification of the key environmental issues for the Waste Treatment sector;
examination of the techniques most relevant to address these key issues;
identification of the best environmental performance levels, on the basis of the available
data in the European Union and worldwide;
examination of the conditions under which these environmental performance levels were
achieved, such as costs, cross-media effects, and the main driving forces involved in the
implementation of the techniques;
selection of the best available techniques (BAT), their associated emission levels (and
other environmental performance levels) and the associated monitoring for this sector
according to Article 3(10) of, and Annex III to, the Directive.

Preface
Waste Treatment v
Expert judgement by the European IPPC Bureau and the TWG has played a key role in each of
these steps and the way in which the information is presented here.
Where available, economic data have been given together with the descriptions of the
techniques presented in the sections mentioned above. These data give a rough indication of the
magnitude of the costs and benefits. However, the actual costs and benefits of applying a
technique may depend strongly on the specific situation of the plant concerned, which cannot be
evaluated fully in this document. In the absence of data concerning costs, conclusions on the
economic viability of techniques are drawn from observations on existing plants.
5. Review of BAT reference documents (BREFs)
BAT is a dynamic concept and so the review of BREFs is a continuing process. For example,
new measures and techniques may emerge, science and technologies are continuously
developing and new or emerging processes are being successfully introduced into the industries.
In order to reflect such changes and their consequences for BAT, this document will be
periodically reviewed and, if necessary, updated accordingly.
