The Swine Research Farm Sterksel (Wageningen UR) in the Netherlands recently started to test the first prototype of a swine toilet.
The idea behind the concept is that pigs can defecate on a relatively small surface. This way the manure can be directly transported away from the pig house, in turn leading to a lower ammonia emission.
The prototype was officially launched by Esther de Lange, Dutch Member of the European Parliament.
