Composting_toilet_tower 3D-Modell

3D model of the composting toilet tower. The composting toilet tower functions as a temporary storage building for feces, and allows it to allready start the transformation to compost (the substance falling on the sloped surface being feces, sawdust and plant leaves (the latter are used as "toilet paper"). The urine is discarded seperatly and can also be used on the agricultural fields, at another time (and diluted with water). The sloped surface allows easy removal of the feces into a waiting vehicle (ie dump truck, horse-drawn cart, ...) After transfer of the compost into the vehicle, it can be emptied on agricultural fields. This way, the nutrients in the human waste are effectively recycled, and the waste disposal system is low in cost, easy, and ecologic. A rotatable plate (yellow in model) allows to direct the compost into the vehicle better. A electric scoop (also yellow in model) automatically scoops the comlpost off the sloped surface. This is necessairy because, although the surface is sloped, it isn't sloped enough for the feces to automatically slide out of the building, and will generally "stick" to the sloped surface a bit. A simple elevator is included aswell, not to allow people to enter the building (these go up via the left ladder and out via the right ladder) but to move the plant leaves and sawdust up.
