Aerobic in situ stabilization of landfills: long-term experience and new developments

The in situ stabilization of old deposits aims for a lasting and controlled reduction of pollutant emissions from the deposited waste in order to diminish expenditure and the duration of landfill aftercare measures. At three landfills in Germany the stabilization operation over a period of 4 - 6 years was completed successfully.

The results shows that leachate contamination is permanently reduced, biological carbon conversion of more than 90% was induced, as biodegradation processes were significantly accelerated and main settlements took place within a short period of time. Based on this positive experience the next large landfills in Germany will be stabilized to reduce the expenditure for closure and aftercare. Moreover aerobic in situ stabilization might be integrated in the new German landfill ordinance.
