Disposing of chemically protected waste wood implies the distinction between surface and pressure treatment. Considering that barked round-wood merely contains, after 7 months open storage, less than 30 g per ton of bark or 25 mg per ton of sapwood, depending on the type of insecticide, the bark or sapwood shavings may be incinerated normally, according to less severe legal prescriptions than for pressure treated wood. Past use poles, destroyed by fungi, will indeed have to be disposed of in specially equipped incineration plants, which respond to strict requirements regarding the waste air.
