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 container; external urinol (optional);

Pros: reuses space of existing toilet, no need for extra space; collects urine for treatment ou use as biofertilizer; provides urinol for men; saves water (no flush needed).

Cons: urine storage for many days can cause extremely bad smell; not very simple to remove the urine container (this would require a door in the structure);

Note 1: you can use either the biodegradable bag or a bucket (10L). The recommendation is to use a bucket, because it is easier to remove/replace. In that case the structure needs to be a bit higher (about 5cm higher if you use a 10L bucket).

Note 2: to make it easier to remove the urine container it is recommended to include, in one of the sides or in the front, a small door.

Note 3: The piece of rubber balloon in the tip of the hose helps to prevent urine smell from coming back up through the hose.

Note 4: Instead of using recycled plastic (6mm thick), the structure can be made of plywood (1cm thick) .

Step 1: Side Structure

Step 2: Urine Container and Urinol

Step 3: Cover

Step 4: UDDT Seat and Biodegradable Bag

Separett® Rescue has been used, but it could be a different one with a similar purpose.

Step 5: Feet Platform

<p>Very interesting idea! </p>
