PCDD/Fs site remediation 1

[Jsafin]

We are currently remediating an old saw mill site that has high levels of PCDD/Fs contamination caused by the use of PCP fungicide use. Currently we are just landfilling the soil, but I am interrested in finding out about possible alternative remediation techniques that can be used to remediate soil that have been contimated in this way. Kinda feels like we are just shifting the problem from one place to another in the long run. And I have checked on the other forums/threads without success...

I'm no expert, but I have heard of onsite incineration being used in site soil remediation.

Usually before a site undergoes remediation, a cleanup plan is proposed and reviewed.

As part of the cleanup plan, alternatives are developed and evaluated. As CVG said, incineration of the soil is one alternative.

One would think that you should have access to a cleanup plan that discusses these alternatives remediation methods.

Having said that, landfilling is typically much less expensive than incineration of soil.

I'm in Finland and as such we are using recommendation by the city's environmental agency and as you have said land filling is also the least expensive option over here at this stage.

My question is based on a personal curiousity as to the availibity of new techniques that we are not aware of as yet. I'm a fairly young engineer that has always been taught to question the way things are done and if there are better options, while the older guys here seem to feel that the way we do it has always been fine before and fulfills customer requirements, so no need to change. Our CEO has challenged me to find better, more cost effective options and this seems to be a good place to find people who know what they are talking about.
Forgive the buttering up with compliments...

It is good to question the way things are done. This attitude can be especially useful in the environmental remediation field where all kinds on inane cleanup techniques are proposed. It is unreasonable to expect 100% environmental remediation results when oil companies can only extract less than 70% of oil in the ground.

Can this be encapsulated? Use as aggregate in concrete?
