Thank you everyone for all the responses, together-thinking. I like this approach

.
A kind of summary of my responses:
If I am not using the sahvings, it will be burnt. Which I know is much worse than using it in a way more efficient way. So I knod of trying to save the thing. I will surely try that soaking method. Sounds interesting. I will also check the ingredients of the glue used and share it with you.
Our land is in a valley almost at the bottom, and have some woods (no edibale things in it) above. The whol e hillside is on clay basis with pine trees on it, so the soil is not so good. The other idea is to scatter the sahvings up in the woods to get some material for soil to hold as much water as possible. This way it will help the system, but not directly effect our garden and fruit trees. I trust nature's healing abality to hande this much of 'toxic' material.
Thanks again and let's heal our soil.
