Experience with an industrial scale-up for the biological purification of CCA-treated wood waste
1997 - IRG/WP 97-50095
The biological purification of CCA-treated wood waste was tested in co-operation of the BFH and the Italian impregnation plant SoFoMe. Chipped poles were infested with the chromium and arsenic tolerant brown-rot fungus Antrodia vaillantii which can transform in the laboratory ca. 90% of the chromium and arsenic into watersoluble salts. These can be leached to 100-200 ppm residual metal content. Th...

Biological detoxification processes - A check list for assessments
1998 - IRG/WP 98-50120
The number of scientific publications on the biological purification of preservative treated wood implies that the biological treatment of wood wastes becomes more and more important. But an information about a successful industrial application is almost missing in all cases. Therefore the applicability of the proposed purification processes is often uncertain. The feasability of such a biological...
