Reactivity of MBT-Waste - A new approach to identify failures of biological tests

The 'Austrian Landfill Ordinance� (BGBl. II Nr. 39/2008) (BMLFUW, 2008) provides requirements for the disposal of wastes. Limit values regarding reactivity such as respiration activity and gas generation sum (by incubation test) or gas evolution (by fermentation test) have to be met before landfilling. On the one hand this approach serves as security and on the other hand these tests are very time consuming (4 and 21 days resp.). Thus, it was aimed for, to develop new analytical tools for the determination of reactivity parameters. Fourier Transform Infrared (FT-IR) spectroscopy was used as a non-destructive method to predict reactivity parameters and to identify errors resulting from inhibiting effects on biological tests.

Keywords:
Mechanically-biologically pretreated waste (MBT), respiration activity, gas generation sum, Fourier Transform Infrared Spectroscopy, multivariate data analysis, Partial Least Square Regression (PLS-R)
