Abstract
The present paper gives a contribution to the understanding of the effects of
variations in maintenance scheduling on the environmental impact of municipal
solid waste incinerators. The proposed approach allows a vision of their impact
beyond the conventional balances. The characteristics of a selected case study
were put forward and discussed. A plant proposed for a region in the North East
of Italy was chosen for the scheduling effects analysis because of the long period
of non-operation of each waste treatment line: 3 months per year as requested
from the local environmental protection agency. The following effects were
discussed on a yearly basis: maintenance stop fractionation, maintenance stop
lasting, maintenance stop seasonal scheduling; the last aspect was discussed also
at device level. The extreme scenario of seasonal stop gave the opportunity of
assessing the highest reduction of yearly average impact from the stack, varying
the season of maintenance: a reduction up to 23% could be obtained for the
pollutants concentration contribution at ground level in the area of highest
impact, comparing the worst case with the best case by a diffusive model. In the
case of more common periods of stops for maintenance the reduction would be
lower. The role of district heating must be taken into account too.
Keywords: environmental impact, incineration, maintenance, municipal solid
waste, operation, scheduling.
