Asbestos analysis of roofing felt / roofing felt waste

Disposal and treatment companies point out that roofing felt waste containing tar, which is disposed of in the course of a refurbishment, can be contaminated with carcinogenic fibres such as asbestos and AMF.

The SBB (Sonderabfallgesellschaft Brandenburg Berlin mbH), for example, requires proof of fibre freedom using the BIA method for each batch of roofing felt waste going to landfill.
