English Abstract The workshop was focussed on the application and
limitation of landfarming and improvement of the technology. At the moment
the application and development of landfarming and other biological methods
are hampered by residual concentrations exceeding the standards set by the
government. Some conclusions: - The procedure of landfarming could be
separated into two parts: intensive landfarming and extensive landfarming.
- It is still possible to optimize intensive landfarming (practised at the
moment) by means of models. - Extensive landfarming could be an alternative
to decrease the residual concentration left after applying intensive
landfarming. This is a new concept in the cleaning of contaminated soil and
should be investigated. - Models and tests should be developed to predict
the residual concentration left after intensive landfarming and the
ecotoxicological risks of the cleaned soil.
