This study presents several results related to the odorous impact derived from organic waste treatment and management plants carried out by the research group. Different raw materials were selected to evaluate the odorous impact and its relationship with their physico-chemical characterization or operational variables. Statistical evaluation through Principal Component Analysis (PCA) groups the odor by its origin or raw material.
In addition, the analysis allows relating the odor with the operational variables, being the odor emission rate (OER, ouE/s) and dynamic respirometric index (DRI, mg O2/gVS·h) the most influential variables in sample variance. NIR technology has demonstrated to be a useful tool to differentiate the chemical composition of the substrates.

The Digital Olfaction Society (DOS) is regularly holding events more or less every two years. The 
The last 19th and 20th of June, the Working Group 41 dealing with Instrumental Odour Monitoring met in Delft, the Netherlands for a couple of days of intensive discussions. One of the Task Groups (TG) dealing with the minimum requirements for instrumental odour monitoring, presented some interesting points discussed in a previous meeting in Düsseldorf, Germany.
