Management of air pollution control residues - Focus on cement-based stabilisation/solidification

A joint CIRIA/ProCeSS/CIWEM project workshop

24 November 2008, London

This event has been postponed - details of the new date will be advertised in due course

Background

Air Pollution Control (APC) residues arise in cleaning of gaseous emissions from a variety of industrial processes. While many APC residues can be recycled or re-used, others contain mixed metal contamination, or have other characteristics of environmental concern and require treatment before land disposal.

In this context, stabilisation/solidification with cement-based binders (S/S) is often considered. Some industry practitioners are still sceptical about S/S, particularly about the long-term performance of treated materials, and how S/S of wastes such as Municipal Solid Waste Incineration (MSWI), APC residues and Electric Arc Furnace (EAF) dust compares with other management options.

The aim of this workshop is to help delegates resolve some of the above problems. This event will also present delegates with information that has been gathered from the TSB funded ProCeSS project which aims to develop ‘process envelopes’ (or ‘operating windows’) for generic S/S of a range of commonly found UK residual waste, including:

MSWI APC residues
EAF dust
Metal treatment sludges
Contaminated soils.

This event will examine options for managing MSWI APC residues and EAF dust and introduce the ProCeSS Screening Protocol for S/S. It will also provide a forum for discussion of related issues amongst practitioners, regulators and local authorities.

A second workshop will be held in 2009, to discuss these issues for the other ProCeSS waste types (metal treatment sludges and contaminated soils).

Programme

10.30	Registration, tea and coffee
11.00	Introduction to Stabilisation/Solidification (S/S) and ProCeSS Julia Stegemann, University College London Julia will introduce the basic concepts of hazardous waste treatment by S/S and the ProCeSS project.
11.20	Introduction to Municipal Solid Waste Incinerator (MSWI) Air Pollution Control (APC) residue management options Chris Cheeseman, Imperial College London Chris will talk about how MSWI APC residues can be managed, highlighting the effectiveness and cost of the different options.
11.45	Defra-funded Characterisation of Cement-Stabilised MSWI APC residues Kathy Lewin, WRc Kathy will present findings of Defra-funded characterisation of cement-stabilised APC residues, including performance against the waste acceptance criteria for hazardous monolithic wastes (monWAC).
12.10	Introduction to ProCeSS screening and extended testing protocols Dr Julia Stegemann, University College London Julia will explain the approach taken in the ProCeSS project to test the performance of wastes treated by S/S and develop performance envelopes.
12.30	Lunch
13.30	S/S of MSWI APC residues Chris Cheeseman, Imperial College London Chris will present the results of the Imperial College experimental programme to develop a process envelope for S/S of MSWI APC residues.
13.50	Plasma treatment of APC residues David Deegan, Tetronics David will talk about the advantages and disadvantages of treatment of APC residues using plasma vitrification at temperatues above 1400oC.
14.15	Introduction to Electric Arc Furnace (EAF) dust management Kevin Linsley, Corus This presentation will discuss how EAF dust is generated and summarise the effectiveness and cost of the different management options.
14.35	S/S of EAF dust Marta Pellizon Birelli, University of Surrey Marta will present the results of the Surrey University experimental programme to develop a process envelope for S/S of EAF dust.
15.00	Panel discussion
15.30	Close
