My investigation project.

From September to October, I 've been researching and writing the project attached below for a special subject called 'Investigation'. It is in Spanish, but I encourage you to translate and read it because it's really interesting and I have worked hard to get the final project you have here:

Anyway, I'll sum up my project to catch your attention: The urea that is extracted from the urine of astronauts in interspace travels is not recycled in any way in the ships. That's why, thinking about a hypothetical human civilization on another planet, the urea could be used in order to originate nitrates that plants would use to accelerate their growth, among other improvements that these compounds provide. Thus, through the advice of two experts in the field of chemistry, three possible reactions have been established for this purpose: a hydrolysis of the urea to generate ammonia that is oxidized to obtain the desired nitrates; the same reaction, but using an enzyme, the urease, which speeds up the first stage of the process; and an acid-base reaction. However, these last two have been discarded since they are unviable in terms of the resources available in a space shift.
