Pilot project of reducing the after-care period
for a municipal solid waste landfill – accelerated
degradation of the organic waste by extensive
interval aeration on BA IV, Landfill Dorfweiher
The district of Konstanz, in cooperation with ISWA,
carried out a research project to reduce the after-care
period of the Landfill Konstanz-Dorfweiher. In this project,
with the acronym “TANIA” (Totale Aerobisierung
zur Nachsorgeverkürzung durch extensive Intervallbelüftung
von Abfalldeponien), the commonly used methods
for landfill stabilization will be combined and fur-
In the framework of scientific monitoring in the pilot
project, further knowledge will be developed.
Measuring data will be collected in closely divided grid
and in a short period of time. For instance information
is available not only of aeration rates and pressures,
but also of gas-, leachate-, temperature- and
settling-developments. Moreover, of how effective the
biofilter for landfill gas treatment works and how much
leachate should be recycled, so that the biological process
could run optimally. This leads to a better understanding
of the procedure during the aerobic stabilization;
and makes it possible to describe the physical,
chemical and biological processes in the project. With
the available data and information, the objective of an
“environmental friendly landfill” can be better described.
Modelling of the target values to reduce the aftercare
period can be carried out as well.
The technical setup for the process, as well as measuring
and controlling technology will be constructed in a
way of modular design. After the stabilization period,
the technical setup is available for other procedures.
With the characteristics gathered in this research project,
the technology can be applied to other sites or
landfill sections.

Ministry of Environment Baden-Württemberg. Duration
of the whole project is 5 years, consists of a 3-yearaeration
phase and a 2-year-monitoring phase.

Development of a simple procedure to evaluate
the emission rates of greenhouse gases from
area sources
Objective of the pilot project is to stabilize the landfill
body in an aerobic way, so that the after-care period
can be finished in a foreseeable period of time. With
the help of the planed procedure, the conversion and
degradation of the organic constituents in the waste
body should be accelerated. Therefore settlement
could take place anticipated and harmful landfill gas
emissions could get enormously reduced. Besides, the
leachate quality could be greatly enhanced.
Objective of the project is to develop a practical software,
to estimate the emission rates of greenhouse
gases from diffusive area sources, by means of tuneable
diode laser absorption spectrometer (TDLAS).
A requirement for emission rates of small area sources
always exists, where, due to mandatory reporting
