In the new Medical Research and Education building, a laboratory animal facility will be built for biomedical research by several UGent researchers. In order to guarantee animal welfare and the quality of the research to the highest extent, thoroughly cleaned housing is indispensable: good hygiene leads to fewer infections and therefore to increased welfare and more reliable results. A bedding disposal system includes a dumping station with a laminar flow hood, a storage container and a vacuum system as depicted in figure 1. At this dumping station our maintenance staff can dispose dirty bedding safe and swiftly on a conveyor belt which leads the dirty material to a shredder. Using a vacuum system, dirty bedding is transported from this shredder to an outdoor closed container through a stainless steel piping framework. A second vacuum pump ensures that dust and air contaminated with allergens are trapped in a series of filters.
