Samenvatting:
As a result of Waste-To-Energy conversion of Municipal Solid Waste Solid,in which high standards of emission control are reached, solid residues
remain that need to be dealt with in an environmentally acceptable manner.
Advanced air pollution control measures in incinerators shift constituents of
concern from air emissions to solid residues, which potentially may lead to
soil and water pollution. The evaluation of the environmental quality of such
residues is necessary before decisions can be taken on the utilization,
treatment or disposal of the residues. The quality of the residues from
Waste-To-Energy conversion is very diverse, as has been identified in the
International Ash Working Group's (IAWG) book 'Municipal Solid Waste
Incinerator Residues (MSWI)'. In addition, the ash management practices are
very different in different jurisdictions. As a result of recent developments
in waste management, consideration is given to recycling and reuse of
residues in construction. This necessitates a judgement on the short and long
term environmental acceptability of such utilization scenarios. In addition
to the environmental aspects, the new material will have to meet technical
specifications similar to those of natural materials traditionally used for
the same purpose. In Europe, utilization of MSWI bottom ash is either
practised (Netherlands, Denmark, Germany) or considered more and more as a
viable option (France, Belgium). In the Netherlands and in France national
legislation has been implemented to regulate utilization of MSWI bottom ash.
In the Netherlands, bottom ash is placed in a special category, because
bottom ash, as currently produced, does not always meet the regulatory
requirements. It is anticipated that improvement in ash quality will bring
the material within the regulatory specifications. Quality control programs
and certification of bottom ash are in progress to ensure production of a
marketable product. 24 refs.
