The mission of the Program for Assistive Technologies for Underprivileged (PATU) is to allow students to practice engineering skills while they develop strong communication and teamwork skills, gain global perspective, and learn social responsibility through projects for persons with disabilities that otherwise could not afford assistance.

Great end to a busy week

Day 4--we visited a final company, GERDAU, that recycles steel. They either use a drawing process to create wire and nails, or rolling processes to make structural components. It was cool to see a company dedicated to recycling materials and also conserving water-90-95% of the water they use in their processes is collected, cleaned and reused (with the majority of the loss being from steam/evaporation).

We then concluded the day with a Brazilian BBQ. Several different types of meats were cooked on the grill and passed around for all to enjoy, and we brought Pringles and Pop Tarts to share. There was swimming, soccer, volleyball, basketball, and music. It was a great time!

Today's reflection: Did you notice Gerdau uses a lot of water in their process? They have a water reclamation system where they clean it and reuse it, with only a 5-10% loss. Water is one of the most valuable resources here in Brazil, and clean water even more. What are you doing to respect or support that? How does this compare to the US? What could be done to improve the water system here?
