title: Usual variables and odour concentration to evaluate composting process and odour impact.
abstract: Organic waste management by means of composting produces unpleasant odours. The odour emissions of composting piles composed of the organic fraction of municipal solid waste and sewage sludge were monitored and controlled by means of dynamic olfactometry. This technique is used to determine the odour concentration expressed in European odour units per cubic metres (ou(E)/m3). To validate the technique, we analysed both respirometric variables and traditional variables such as total organic carbon and pH during composting. Finally, a dispersion model was used to evaluate the impact of the odour emissions of the wastes on neighbouring areas, not finding any differences in the cases evaluated.
