Paper Recycling Fiber Recapture, Erin Riley

Honors Theses

The goal of the Yoda Chemical Company Paper Recycling Fiber Recapture project and subsequent report was to identify and recommend plant optimization opportunities associated with the potential recovery of five waste streams. Additionally, an analysis of the upgrade’s design was completed in order to determine the economic viability of fiber recapture. Beginning the analysis, the five waste streams were identified and analyzed. The waste streams include the top liner, back liner, and filler liner primary cleaner rejects on the K1 machine, the common rejects from under the K3 paper machine, and the tertiary cleaner rejects from stock preparation.

Two different …

Product Realization Capstone: Element Proof Safety Steps For Willie Price Lab School, Catherine Thomas, Allan Heuerman, Jared Mumme

Honors Theses

The purpose of this document is to describe the process we took to complete our capstone which paired the Center for Manufacturing Excellence with the Willie Price Lab School. The goal of the capstone was to remake step stools for the students of Willie Price, as the last stools failed to withstand weather damage. However, with the COVID-19 pandemic, plans were hindered, shifting the goal from actually producing the steps to creating instructions so that a younger Center for Manufacturing class could complete the production at a later date. Standardized Work Instructions, a detailed production plan, and engineering drawings were …

The Problem-Solving Workshop: Adapting Process Improvement Methodologies For K-12 Educators, Madison Chan

Honors Theses

Lean and Six Sigma have been lauded in the manufacturing sector for their ability to streamline processes, reduce waste, minimize variation and defects, and improve the bottom line. Although these methodologies have begun to spread to other industries, their impact has been relegated to certain areas and has largely missed others. One area that bears strong consideration is education. Education is heavily process-based and notoriously tight on resources. It is hypothesized that if educators were taught the basics of these strategies and were able to implement them in the classroom setting, the effectiveness of both teaching strategies and classroom operations …

Controller And Headset Stand: Designing And Manufacturing, Tyler Butler, Chad Gutierrez

Honors Theses

This report shows how our Senior Center for Manufacturing Excellence team took our product, a controller and headset stand, from an idea into a mass producible product. We first identified the problem of headphones and controller storage and sought to solve it through our product design. Market research was performed to ensure that this would be a successful product in today’s marketplace. The trials of prototypes demonstrated what features could and could not be implemented into the design of the product. The group then designed a manufacturing plan for the product and found the projected market for the product. This …

Understanding Individual Color Perceptions Within Print And Digital Media, Morgan Haskins

Honors Theses

Color is a subjective attribute that is seen differently by each individual and this research is intended to build upon the subjective nature of color perceptions. This research aims to determine the effect of subjectivity on print and digital design and of extended gamut printing and effective color management on color perception. The significance of understanding color perception is directly applicable to consumer perception of designs using color. If designers want their brand to be immediately recognized and be positively accepted, they must be able to accurately reproduce their brand colors with little to no color difference and be able …

Development Of A Flexible Printed Paper-Based Battery, Justone Crosby

Honors Theses

Market demand for flexible electronics continues to grow, which, in turn, increases the demand for flexible energy storage devices. There are several types of energy storage devices available, including the alkaline (Zn-MnO₂) battery, which is the subject of this project. This project's objective was to develop a flexible, printed paper-based battery, which may be a sustainable solution to the increasing market demand. This device is low-cost and can be manufactured commercially using a scalable process.

The proposed device is an alkaline flexible cell, whose components can be printed onto paper. This alkaline system includes a zinc-based negative electrode …

Comparison Of Pretreatment Methods For Cellulosic Ethanol, Michael Eaton

Honors Theses

Bioethanol provides a great alternative to regular ethanol sources because it uses secondary substrates that are byproducts of other industries, rather than substrates that compete with food products. The technology is available for industrial bioethanol production, but the production costs just aren’t competitive enough with traditional ethanol production. The goal of this project was not to prepare a proposal for a bio-ethanol plant with all of the associated costs and financial calculations, but rather to provide a direct comparison of two pretreatment methods to highlight which factors could make one method less costly than the other. Pretreatment is a critical …
