In Asia, a lot of toilets (and sewers) are not able to handle toilet paper. This is mostly because of the thin sewer-pipes. The people, however, found a solution for this shortcoming, a basket next to the toilet, where used toilet-paper and other waste is thrown in. Once a week it is thrown away in the normal trash-can.
WeiShi, to be installed when a toilet is placed or renovated, collects used toilet-paper and other waste in the restroom hygienically. It shreds the paper and waste and adds a liquid that neutralises all smells and bacteria growth. The pulp that remains can be thrown away hygienically and/or can be recycled as paperwaste.
