Team Vision for Problem Definition Phase

Our team goal was to more clearly define what is needed for this project by conducting customer interviews. We planned to meet with customers from 4 Walls Rochester and the Enlace Project to set customer requirements. We also planned on setting engineering requirements, and research many aspects of the project during this phase.

Our team met with some of our customers from 4 Walls Rochester, but not with Enlace Project due to schedule conflict. We gathered information on the project and set customer requirements. We also engineering requirements, and split research between the group and discussed as a group.

Project Summary

Currently in El Sauce, Nicaragua there is a large amount of plastic bottle waste that has lead to the a need for a manufacturing process to recycle the plastic bottles into usable products for the local citizens. The full project summary can be found here.
