recycling fly ash in the Netherlands

["Susan K. Snow" <sksnow@1stnet.com>]

Some people were interested in the forwarded 'Recycling' fly ash e-mail 
which I received and shared.  Let me share this again without an 
attachment to open.

Ing. Ferdinand Engelbeen replied on your message from 10/02/96:

In The Netherlands one third of the E-filter ash of incinerators is mixed 
with asphalt. The total dioxin I-TEQ mixed this way with asphalt is 
around 300 g/year.

The total dioxin emission of one mixing installation was measured. When 
these emission figures are used to calculate the total emission of all 
asphalt mixing installations in The Netherlands, the total emission can 
be estimated to be 0.3 g I-TEQ/year.

The amount of fly ash released by wear out of the asphalt by traffic is 
calculated/estimated to be 0.6 g I-TEQ/year. This is widespread over all 
roads where this asphalt mix is used. That seems not to be an 
environmental or health problem.
