Emission reduction measures for bioaerosols from composting - Results fromresearch and execution

Similar to odour problems, bioaerosol emissions in the surroundings of wast e treatment plants are often a cause for complaints by the neighbours conce rned. In the past, some of these complaints have led to legal disputes that resulted in cost-intensive plant modernisation and optimisation. Therefore , emission reduction measures have to be taken into consideration already i n the planning stages or must be realised within the frame of plant licensi ng and control. Achievements of various bioaerosol reduction measures are e xemplified. So far, the findings are not satisfactory for a comprehensive a ssessment of process technology as lacking uniform frame conditions for mea suring and differently applied sampling and analytical methods lead to an i nsufficient comparability of research results. The acquirement and document ation of further basic data as well as their professional discussion are co nsidered compulsory for an appropriate assessment.
