Field Trip

This is Alex. On Friday we had our field trip to the Brazos River Authority which is where they make the biosolid fertilizer. It was a very interesting tour and we learned a lot of things about biosolids that we would never have found out before. For example, 100% of Belton's waste goes to the factory, and 66% of Temple's waste goes there. All that stuff smelled absolutely toxic. We also learned exactly how the biosolids are processed. It is a long and complicated process and I am quite glad that my mother was paying such strict attention.

They have to take the water and filter out all the large bits of junk.

Then, they completely remove all the water to turn it into sludge cakes (which smell worse than they did before). After that's done, they put it through another machine to make sure it's composed of exactly the right minerals and microscopic organisms, and then they pile it up so big that it combusts itself like a compost heap.

Believe me, it's more complicated than that, but we're going to go over it in more detail on Sunday. We are also, hopefully, going to get some more work done on the arrows and floodgate mission. I think we need to use the ultrasonic sensor to see when we're the right distance from the far wall before stopping and turning. If we can get the distance down straight, I'm pretty sure it'll make it a lot more consistent. So, that'll be one of our main objectives. That's all for now. bye.
