Odour Prevention and Control of Organic Sludge and Livestock Farming

An important aspect of the treatment of sludges and slurries is the emission of odour. International cooperation in odour control and odour measurement is onlypossible if the results are comparable. For this reason, Working Party I of the COST Project 681 established a sub-group to study the international developmentof odour measurement techniques. The inventory made by this sub-group resulted in a proposal for a workshop on olfactometric measurement in order (1) to exchangeexperiences with different olfactometers, and (2) to consider the possibilities of more harmonised measurement. As odour measurement is not a goal in itself but astep on the way to odour control, it was decided to combine this workshop with a workshop of the FAO Sub-network 2 devoted to reduction of odour in animal farming.
