Investigation of residual waste for AVA Abfallverwertung Augsburg
The municipal company AVA Abfallverwertung Augsburg engaged bifa Umweltinstitut to perform a residual waste analysis, in order to determine the main parameters of the delivered residual waste.
The calorific value, the water content and the chlorine content of the waste in particular, are significant for the life of the incineration plant. Equally, the contaminant load of the material flows also plays an important role in the process. As literature values only were available to date for the characterisation of the residual waste quantity delivered, bifa was engaged to examine the delivered residual waste streams. To this end, in 2019, 2019 examined a total of 18 chemical and 3 physical parameters of the delivered residual waste. The sampling took place during a period of high precipitation in winter as well as during a low-precipitation summer campaign. In each investigation period, 13 areas were sampled at vehicle level, corresponding to 425 Mg residual waste. The districts from which the waste comes were selected and analysed in a differentiated way, according to their settlement structure.
The sample preparation took place in a multi-stage process through to double and triple determination of the selected parameters in the laboratory. Some values were found to deviate substantially from the previously assumed literature values.
