How can we improve the effectiveness of biotechnologies for treating
waste, sediments and polluted soils? One way forward is to overcome certain
limitations, particularly those relating to the biodegradability and
bioavailability of pollutants, by combining non-biological processes. By identifying the processes that limit the effectiveness of bioprocesses and
pinpointing the solutions that can overcome these limitations (process sheets
in the report), the authors draw up a table of the most illustrative
combinations of processes, such as:
- the use of mechanical processes for the preparation of organic waste (such as
"mechanical-biological" pre-treatment),
- the preparation of polluted soil prior to treatment in a biotertre,
- the use of wet oxidation as a pre-treatment for WWTP sludge.
