Energy content and chemical changes in energy crops under landfill leachate irrigation
Abstract
Willows and poplars have been used for recultivation of landfill sites under landfill leachate irrigation. Plants are used as a carbon neutral energy source, beside their contribution to treatment and minimization of the landfill leachate and stabilisation of the recultivation substrate. Irrigation of landfill leachate, which contains - among other compounds - high salt contents, leads to changes in the biomass production, the morphology and the C/N content in the plants. These results were found in a pot experiment, in which Salix viminalis, Salix caprea x cinerea, Salix purpurea and Populus nigra were screened. The observed changes raised the question of changes in the energy content and structure of the wood, which are investigated by simultaneous thermal analysis (STA) and bomb calorimeter experiments. Modelling of the results from the STA measurements and correlation with the bomb calorimeter analysis are aimed at. Finally the environmental stress "landfill gas" and its effect on the buring profile will be evaluated.
