The slag heap of Hénâ – Asbestos processing

As with the disposal of the ash, the disposal of potentially contaminated soil is proceeding apace. No less than 30,000 tonnes have been removed from this part of the slag heap alone.

The site is divided into several zones


A, C and C' = treated areas
B = analysis and sorting area
D= sorted and healthy soi




Campaigns to measure the air concentration of asbestos fibres on and around the Hénâ slag heap are regularly carried out by the independent company SGS. The conditions imposed by the permit are 10 times more restrictive than those required by Belgian legislation. All measurements carried out to date show that the results comply with the imposed criteria.
