Bioengineering and Environmental Engineering Possibilities for emission prevention and reduction

The animal production stresses the environment with odor, ammonia, particulate matter, germs and aerosols. Therefore the demand of emission reduction is incontestable, although the available data needs further recondition. Nevertheless approving authorities preferentially focus on exhaust air treatment in poultry production. Time course measurements in stables hardly reveal causally determined correlations in view of emission behavior. At least the dimensions of influences can be assessed with the software "DEMAP". This is not possible with a bare estimation of emission factors on basis of the VDI 3894. With modern analytical methods agriculture is called in this regard to develop target functions for emission reduction and the use of filter techniques, also in terms of an improvement of animal welfare.
