摘要

In the Netherlands manure treatment is applied because of high off-farm disposal costs. Gaseous emissions (ammonia, odor, and greenhouse gases (methane, nitrous oxide)) from six different systems for pig slurry treatment were measured. Emissions appeared to be are mainly determined by treatment technique and not by treatment capacity of the system. Biological N-removal systems are responsible for a large increase of greenhouse gas emissions. In comparison with a regular farm without manure treatment greenhouse gas emissions are three- to ninefold. Only after process optimization use of such systems can be justified.
