Hazardous-material remediation
Removing KMF & old mineral wool in Berlin
Old glass or stone wool in your roof, façade or suspended ceiling? Man-made mineral fibres (KMF) installed before 2000 are classified as suspected carcinogens and must not simply be removed. We remove KMF in Berlin safely – with protective measures, low-dust packaging and proper disposal as hazardous waste.
How we remove KMF safely
Assessment
We check the material and installation year – old mineral wool (pre-2000) is classified as a suspected carcinogen.
Protective measures
Containment, protective clothing and extraction prevent fibres from being released.
Removal & extraction
Controlled removal of the insulation with industrial vacuums and low-dust packaging.
Disposal with proof
Proper disposal as hazardous waste including complete documentation.
When Old Mineral Wool Has to Be Removed
Man-made mineral fibres – glass and stone wool – are only a problem if they were installed before the year 2000. Older fibres are respirable and poorly soluble in the body; they are classified as suspected carcinogens and fall under TRGS 521. Removal costs €8 to €20 per square metre plus €100 to €200 per tonne in landfill fees.
| Feature | Old KMF (pre-2000) | New mineral wool |
|---|---|---|
| Carcinogenicity index | KI below 40 | KI of 40 or above |
| Bio-solubility | low | high |
| RAL quality mark | absent | present |
| Classification | suspected carcinogen, TRGS 521 | considered safe |
| Disposal | hazardous waste, €100 – 200/t | construction waste, €40 – 80/t |
On site, old mineral wool is usually yellowish to brown, dusts heavily when handled, is often installed without facing and carries no marking at all. New material shows the RAL quality mark. Where the installation year is unclear, a material sample decides.
Where It Is Found
Pitched roofs and top-floor ceilings are by far the most common location in houses, followed by pipe and boiler insulation in basements, suspended ceilings and drylining in commercial buildings, and façade insulation behind curtain walling – frequently in combination with asbestos panels.
The Process Under TRGS 521
Assessment and sampling, dust-tight containment (with negative pressure for larger volumes), controlled low-fibre removal with pre-wetting, extraction using class H industrial vacuums, dust-tight packaging in labelled big bags, fine cleaning of the area, and disposal with weighing slips and a disposal certificate.
Across Berlin and Brandenburg
We carry out KMF remediation throughout Berlin and the surrounding area. Where it forms part of a strip-out or a demolition, we coordinate both from one source – see hazardous-material remediation.
Common questions about KMF
What is KMF and why is it dangerous?
KMF stands for man-made mineral fibres – glass and stone wool. Old insulation installed before the year 2000 often contains respirable fibres classified as suspected carcinogens. These fibres are released during removal – which is why it belongs in expert hands.
May I remove old mineral wool myself?
For larger quantities or commercial settings this is not permitted. Old KMF must be removed with protective measures under the Hazardous Substances Ordinance and disposed of as hazardous waste. We handle this safely and with disposal documentation.
How do I recognise dangerous mineral wool?
Rule of thumb: insulation from before 2000 is critical, newer material (with the RAL quality mark) is considered safe. Old KMF is usually yellowish to brown, dusts heavily when handled and carries no marking. If in doubt, we assess the material on-site – free and non-binding.
What does KMF remediation cost in Berlin?
Removing old mineral wool costs €8 to €20 per square metre plus €100 to €200 per tonne in landfill fees. New mineral wool is much cheaper to dispose of at €40 to €80 per tonne, which is why establishing the material before costing pays off.
Where is KMF typically found in Berlin buildings?
Most often in pitched roofs and top-floor ceilings, also in pipe and boiler insulation in basements, in suspended ceilings and drylining in commercial buildings, and in façade insulation behind curtain walling, where it frequently occurs together with asbestos panels.
Can you remediate KMF and asbestos together?
Yes, and with Berlin building stock it is usually necessary. KMF falls under TRGS 521 and asbestos under TRGS 519. We cover both with our own qualified staff and coordinate the work so the area only has to be contained once.
