I have been compiling information on odour emission rates for some years. These have been complied from publicly available reports on the internet, planning portals or in published reports. If you wish any data to be removed, please contact me through this website. As far as I am aware, this is the only publicly available odour emission datbase in the UK.
There is a new feature that allows the user to select the median and a user selected percentile odour emission rate values for waste water treatment processes. This is a very useful facility for sensitivity studies to test confidence in the outcome of your assessment. See my file notebelow with more information on this facility.
The database is updated regularly and is available here, note I am gradually editing the spreadsheet to have consistent formatting of units.
I always welcome new data to include in this database.
