Cherrie Ruan, class of ’27, is an undergraduate Civil Engineering major at Lehigh University; her metal forming processes of interest include forging and surface finishing. [1] What excites you about this project? I am excited about this project because of its intersection with infrastructure and public policy. As an aspiring civil engineer, I […]

This week we focused on preparing our salts list and setting up our experiment. I researched different salt prices for our salt lists and looked more into the chemistry of the salts. We also attended a meeting with applied separations on Thursday, where our experiment was discussed. Additionally, I made a slide presentation for

This week was spent getting a poster ready for the summer expo on August 3rd and preparing for the experiment of the project for the summer. I was in contact with both the Physics and Chemistry departments to secure equipment, space and guidance for the experiment and to confirm the materials used in the

Continuing building on our experiment, this week I worked on writing some pre-experiment reports. I followed a lab report template from a previous class I did work for, in order to organize the information for the experiment easier. Some pre-experiment writing I worked on include the purpose/goal of the experiment, as well as the

This week, quite a few short term goals were completed by the group. We were able to visit the facility of Clean Earth, a universal E-Waste recycling company located in Allentown. The visit provided us with helpful information in the organization of their process and value of separation of parts. One of the main

This week we had a meeting with Clean Earth where we learned more about E-waste recycling and their processes. I gained a better understanding from a business perspective and kept new considerations in mind when it comes to safety and cost/revenue. Overall this visit was successful and very engaging as we saw all the

On Monday we had a meeting with Professor Animesh Kundu, where we talked about ball milling. This meeting was very insightful and I was made aware of issues that can come with ball milling PCBs which I had not thought about before. This week I researched more about ball milling and look into the

This week, my old high school generously donated ten chromebooks for our group to use in our experiment, securing the material needed for our future research. Due to their dangerous nature, the group removed each battery pack and put them in a secure location so as to avoid any unwanted situations. As we will

This week I looked into methods that occur in the disassembly process. I studied subcritical water debromination, and debromination efficiency on PCBs with various additives to a ball mill. On the side, I did some research on the ball mill itself and the balls that you use for the machine. PCBs contain BFRs

Last week’s research into using subcritical water in the debromination process in separating the metals of printed circuit boards from the plastics. While this did mean that the same process that uses supercritical water could be done with less energy to maintain the pressure needed for a supercritical state, massive amounts of energy would
