Soy- Based Flexographic Ink For Linerboard Printing, Rahul Ramchandra Pingale Dec 2018

Soy- Based Flexographic Ink For Linerboard Printing, Rahul Ramchandra Pingale

Master's Theses

Many printing inks use volatile solvents in the formulation, which are hazardous to the environment from emission of VOC’s and at the same time, synthetic resins in these inks are not biodegradable. These problems with the fluctuating and rising price of petroleum are main reasons to look for new resources for making more environmentally friendly printing inks. The majority of the commercially available water based inks are formulated based on using acrylic resins, synthetic colorants, solvents/water and additives, which are the common main components for formulating printing inks. In this research, soy proteins were tested for their suitability ...


Screen Printed Moisture Sensor On Barrier Coated Sbs Board: The Characterizations Of The Hemicellulose-Based Biofilms And Their Applications For Smart Packaging, Ruoxi Ma Aug 2018

Screen Printed Moisture Sensor On Barrier Coated Sbs Board: The Characterizations Of The Hemicellulose-Based Biofilms And Their Applications For Smart Packaging, Ruoxi Ma

Dissertations

Fiber-based packaging materials have many advantages over their petroleum-based plastic competitors, such as sustainability, recyclability and stiffness/weight ratio. However, the poor barrier properties and sensitivity towards moisture are the main challenges for their extended use. Therefore, there has been a need to provide a biodegradable and biocompatible biopolymer packaging material with improved barrier properties for food and pharmaceutical packaging. Also, the moisture loss/gain problem causes a lot of waste every year. Therefore, there is a need of better tracking and sensing methods attached to the package in order to control the moisture level along the supply chain. To ...


Pyrolysis Of Plastic Waste From Medical Services Facilities Into Potential Fuel And/Or Fuel Additives, Bright Kweku Ansah Baiden Aug 2018

Pyrolysis Of Plastic Waste From Medical Services Facilities Into Potential Fuel And/Or Fuel Additives, Bright Kweku Ansah Baiden

Master's Theses

Limited space and high costs for landfilling as well as increasing regulations in plastic waste disposal, has led to high operating costs for organizations involved in managing plastic waste from medical facilities which led to the need to investigate an alternative option such as pyrolysis. The overall goal of this study was to evaluate pyrolysis as a means to repurpose plastic waste obtained from medical service facilities into fuel and fuel additive compounds, with two objectives involving, (1) to examine the effect of heat input (as voltage) and reaction/residence time; and (2) to evaluate the effect of the plastic ...


Optimizing Frosted Mini-Wheats' Finished Food Cooling Process, Jessica Graves Apr 2018

Optimizing Frosted Mini-Wheats' Finished Food Cooling Process, Jessica Graves

Honors Theses

Analyzing energy intensive processes in industry is crucial for improving sustainability, lowering costs, and increasing profit margins on products. Material and energy balances were performed to identify process losses in the cooling of Frosted Mini-Wheats. Existing cooling technology was compared to alternate technology available on the market, and a cost analysis was performed to compare all options explored. Recommendations were made to the system to potentially reduce the line's energy usage and downtime, with the objective of creating a more sustainable and efficient process.


Distillation Optimization In The Pharmaceutical Industry, Daniel Vanzweden Apr 2018

Distillation Optimization In The Pharmaceutical Industry, Daniel Vanzweden

Honors Theses

Distillations are commonly used throughout industry to perform separations by phase change, producing a liquid phase and vapor distillate. However, the process of distilling can be slow and energy intensive, providing a limitation in the production process. Possible improvements to current distillation systems were considered on the basis of thermal efficiency, material throughput (cycle time), and material tolerance. Consideration was given to ensure maintenance is straightforward and relatively quick, as fouling, contamination and tank utilization were concerns. Economic viability of the improvements was completed to determine the project benefit. The optimized design offers increased efficiency for production lines.


Natural Polymer Barrier Coatings For Oil And Grease Resistance, Andrew Kathan Apr 2018

Natural Polymer Barrier Coatings For Oil And Grease Resistance, Andrew Kathan

Honors Theses

Many barrier coating formulations currently used for oil and grease resistance development in the paper industry have issues with sustainability, biodegradation, or have health concerns associated with them. This thesis tests two starches as barrier coatings to develop oil and grease resistance for food grade packaging sheets. Starch is compatible with almost all papermaking chemicals, is biodegradable, and is easily treated in wastewater systems making it a great candidate to create a more sustainable barrier coating. Cooked hydrophobic starch esters have a unique shear-thinning rheology that allow for high solid starch coatings to be applied with a reduced risk of ...

Optimization Of Toaster Pastry Icing Preparation And Application, Rebecca Martus Apr 2018

Optimization Of Toaster Pastry Icing Preparation And Application, Rebecca Martus

Honors Theses

The Kellogg Company is interested in optimizing the way the icing for a baked good is prepared and applied during production. The current method has not been significantly changed since the item was first introduced over 50 years ago. A new process was developed to make a more efficient preparation and application of the icing operation. New equipment was identified based on established methods in the food industry. The new equipment and process was verified after the mass and energy balances were calculated. A capital and operating cost analysis was performed to determine if the introduction of the new process ...
