Attachable Dry Toilet - Prototype 3 (Banheiro Seco Acoplável - Protótipo 3)

History: This prototype was developed by me in the context of a social business project, named S+ (Sustainable Sanitation), incubated at the Yunus Social Business Brasil (1st cycle). Also participated in the project Thais Cosa, Cecília Rodrigues, and Ilana Goldsmid.
Warning: You are required to have knowledge on composting techniques before trying to build/use this toilet.
Features: UDDT (Urine-Diverting Dry Toilet); this project uses Separett® Rescue (but actually it could use any similar piece from another third party); reuses space of existing regular toilet; urine is not collected; external hand urinol for men (optional);
Pros: reuses space of existing toilet, no need for extra space; no need to collect urine; easier to maintain and operate; saves water (no flush needed).
Cons: urine is not collected (although the tube can always be redirected to an external container anyway)
Note 1: It is not necessary to remove the original toilet cover, the structure has been resized to avoid that (see last picture).
Note 2: the "external hand urinol" is actually a simple 500ml plastic container which can be used to collect urine, which afterwards is thrown in the UDDT, followed by some water to clean it up.
Note 3: It is optional to cover the bucket with a biodegradable plastic bag.
Note 4: The piece of rubber balloon is used only to help keeping the pieces tightly connected.
Note 5: Instead of using recycled plastic (6mm thick), the structure can be made of plywood (1cm thick) .

There has been an adjustment in the length of the structure to avoid the removal of the existing toilet cover.
