Residue-free and sustainable removal of contaminants

Remediation of contaminated wooden structures

Research News /

In Germany, there are around three million buildings that are contaminated with the toxic wood preservatives lindane and pentachlorophenol (PCP). Previous measures for minimizing contamination include insulating contaminated areas or disposing of treated wooden building materials as hazardous waste. However, these measures are neither sustainable nor cost-efficient. In the CycloPlasma project, researchers at the Fraunhofer Institute for Building Physics IBP are developing a new type of process to remove these decades-old contaminants — in the air as well as in contaminated wooden structures — in a way that is residue-free, sustainable and does not pose a health risk. For this purpose, the scientists have combined an innovative adsorber material with plasma technology.
