Re. advertisemeent in the Evening Post. – 25/04/12
I was involved with the old Incinerator Plant until I retired in 1997.
I spent some time looking at alternative ash disposal options which I am sure that the current officers are familiar with. At that time bottom ash was not considered to be hazardous, the more serious peoblem was disposal of fly ash. We should, I believe, ensure that our current fly ash dispsoal methods do not result in future environmental problems.
There are several processes which enable the small quantities of dangerous contaminants to
be extracted from the fly ash and rendered inert, for example by mixing with waste glass and then treating by vitrification.
The problem, as always, is the cost, both capital and revenue.
I am surprised that metal, both ferrous and none ferrous are still being disposed of by land reclamation.
Technology has moved on in the last fourteen years and, as I have said, I am sure the officers currently dealing with the problem are familiar with current treatment methods, I hope however that these observations may be helpful .
