Non-Sterile Fermentation Of Food Waste Using Thermophilic And Alkaliphilic Bacillus Licheniformis Ynp5-Tsu For 2,3-Butanediol Production, Joshua A. O'Hair, Qing Jin, Dajun Yu, Jian Wu, Hengjian Wang, Suping Zhou, Haibo Huang

Agricultural and Environmental Sciences Faculty Research

Conversion of food waste into 2,3-butanediol (2,3-BDO) via microbial fermentation provides a promising way to reduce waste disposal to landfills and produce sustainable chemicals. However, sterilization of food waste, an energy- and capital-costly process, is generally required before fermentation to avoid any contamination, which reduces the energy net output and economic feasibility of food waste fermentation. In this study, we investigated the non-sterile fermentation of food waste to produce 2,3-BDO using a newly isolated thermophilic and alkaliphilic B. licheniformis YNP5-TSU. Three unitary food waste samples (i.e., pepper, pineapple, cabbage wastes) and one miscellaneous food waste mixture were respectively inoculated with …


Maleic Anhydride Compatibilized Peach Waste As Filler In Polypropylene And High Density Polyethylene Biocomposites, Caralyn Wong, Stephanie Jung, Joongmin Shin, Ajay Kathuria Aug 2020

Maleic Anhydride Compatibilized Peach Waste As Filler In Polypropylene And High Density Polyethylene Biocomposites, Caralyn Wong, Stephanie Jung, Joongmin Shin, Ajay Kathuria

Master's Theses

It is estimated that roughly 103, 515 tons of peach waste is produced annually in the US. The majority of the waste is disposed of in landfills, which contributes to climate change as they release 93 million metric tons of CO2 equivalent. Peach waste principally consists of remaining stone and seed after flesh removal. The agro-waste includes both cellulose and lignin, which can be utilized as a filler in plastic packaging to reduce carbon footprints and material cost. The objectives of this research are (1) to develop peach flour (PF)-filled biocomposites with a polyolefin matrix using maleic anhydride-g-high density …


Does Circularizing Source-Separated Food Waste Present A Risk To Our Food?, Astha Thakali May 2020

Does Circularizing Source-Separated Food Waste Present A Risk To Our Food?, Astha Thakali

Electronic Theses and Dissertations

About a third of the food produced annually is wasted. Food waste recycling can be a way to close the loop and attain a more sustainable food system, however, the system must be carefully monitored and managed to avoid the introduction and build-up of contaminants. To study the potential presence of contaminants in food waste, source-separated food waste was collected and screened for five classes of contaminants (physical contaminants, heavy metals, halogenated organic contaminants, pathogens, and antibiotic resistance genes) from two separate regulatory environments (voluntary vs mandated food separation). The regulatory environment did not affect the level of contamination, except …

Bridging The Food Gap: Founding And Sustaining A Food Recovery Network Chapter At Wku, Elaine Losekamp Jan 2020

Bridging The Food Gap: Founding And Sustaining A Food Recovery Network Chapter At Wku, Elaine Losekamp

Mahurin Honors College Capstone Experience/Thesis Projects

Food waste is a pervasive global issue with many environmental and social repercussions. While about one-third of all food produced for human consumption goes to waste, many people in the United States and the world are affected by food insecurity. Food recovery, the process of rescuing edible food that would otherwise go to waste and delivering to hungry people, is an effective solution for both food waste and food insecurity. The author of this capstone created a food recovery program at Western Kentucky University (WKU) in January 2019 and has grown the program’s scope and impact since that time. This …
