| Keywords: Composting toilet tower concept.png en A schematic of the composting toilet tower concept conceived by KVDP toilets defecation/urination are placed on the first floor accessible via ladder stairs or manual lift; a manual lift would also facilitate delivery of the sawdust ; this floor is located on a certain altitide so as to facilitate the emptying of the tower which will need to be done in the period of fertilisation the exact time depends on the local climate and the crops grown As emptying is thus only done once a year the section of the tower holding the compost would need to be made large enough to be able to store the entire generated excrement+sawdust for the intented population eg some 8 people Emptying can be done into a variety of vehicles carts and even wheelbarrows This is made possible due to the clever opening based on the Clivus multrum system and the attached metal plate below which can be rotated Also the flow of compost can be regulated trough regulating the opening via the lids F 3 lids are to be foreseen 1 for each part of the opening see G The compost-scoop can be manually powered eg by allowing to push it using the feet of several operators leg-muscles are generally stronger than arm-muscles Note that as mentioned at the File Composting_toilet_with_UrineDiversion-Dehydration jpg atleast 2 urine collection bins need to be used and they should be made of glass or transparent plastic Again if needed a black board can be placed behind the bins Note that just as with regular composting toilets sawdust needs to be added in the appropriate C/N carbon-nitrogen ratio to the faeces to obtain compost introduced via the defecation hole own KVDP 2010-01-22 Composting toilets Urine diversion | ||||
