Problem Statement
My group is working on the Disaster Toilet. In this project cycle, we will be completing the Conceive and Design phases from the CDIO phase.

Project Plan
Our group's plan for the next four weeks is to come up with the basic components that we want our toilet to be made from, as well as how to deal with waste in the most efficient and effective way possible. We will also need to design a method for storing information such as methane gas, liquid content etc from our toilet.

Week1 Narrative
-We found the basic materials for our toilet: Wood, Cardboard, Plastic

-We drew our designs in our Engineering Notebooks and compared them

-We researched what materials were more efficient and cost effective

-We devised a game-plan on how to proceed with the Disaster Toilet

Week2 Narrative
-We researched mechanics involved on assembling plastic components

-We researched possible means for dealing with waste/odor

-The next steps needed are to come up with practical ways to deal with the waste, possibly including the use of bacteria or a storage tank of some sort

Week3 Narrative
-I have learned that there is an anaerobic bacteria called Anammox. It is used today in water purification for breaking down ammonia.

Definition: Annamox bacteria, also known as brocadia anammoxidans, can survive without using oxygen, which is incredibly helpful for us designing our relief toilet. This bacteria feeds off of waste (ammonia mainly) and is abundant in yeast and the open oceanic waters. The byproduct of it is a chemical called hydrozine, the main component of rocket fuel. Although this sounds exciting, it is such a small amount that it is nearly insignificant.

Week4 Narrative
-My personal tasking involved designing a method of separating the feces from the urine on the toilet.

-Initially, I thought that people could just use the toilet to poop in to, and pee in the woods or in nature elsewhere (not that big of a deal in a disaster scenario).

-Then, I realized that the front of the toilet could be lifted higher than the back with some holes, naturally separating the two. The urine could flow into the ground or into a separate container entirely, being disposed of at a later point. This proved to be more effective and practical for the amount of people who would need to use the relief toilet.
