Waste To Phosphorus: A Transdisciplinary Solution To P Recovery From Wastewater Based On The Triz Approach, Anna Jama-Rodzeńska, Andrzej Białowiec, Jacek A. Koziel, Józef Sowiński 2021 Wroclaw University of Environmental and Life Sciences

Waste To Phosphorus: A Transdisciplinary Solution To P Recovery From Wastewater Based On The Triz Approach, Anna Jama-Rodzeńska, Andrzej Białowiec, Jacek A. Koziel, Józef Sowiński

Agricultural and Biosystems Engineering Publications

Phosphorus (P) is a limited yet essential resource. P cannot be replaced, but it can be recovered from waste. We proposed the TRIZ approach (Teoria reszenija izobretatielskich zadacz - Rus., Theory of Inventive Problem Solving - Eng.) to identify a feasible solution. We aimed at minimizing the environmental impact and, by eliminating contradictions, proposed viable technical solutions. P recovery can be more sustainable based on circular economy and 4Rs (reduction, recovery, reuse, and recycling). The TRIZ approach identified sewage sludge (SS) as waste with a large potential for P recovery (up to 90%). Successful selection and application of SS management and P ...

Long-Term Changes In Soil Surface Properties As Affected By Management Practices In A Wheat-Soybean, Double-Crop System, Machaela Morrison 2021 University of Arkansas, Fayetteville

Long-Term Changes In Soil Surface Properties As Affected By Management Practices In A Wheat-Soybean, Double-Crop System, Machaela Morrison

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Long-term agricultural sustainability and productivity are controlled by the integrative effects of different management practices on the soil. Many Arkansas producers use the double-crop system to grow soybeans [Glycine max (L.) Merr] and wheat (Triticum aestivum L.). Studying combinations of different, non-traditional, alternative agricultural techniques may help producers better understand the long-term implications of various management practice options on sustainability and productivity. The objective of this study was to evaluate the effects of agricultural management practices, including residue level, tillage, irrigation, and burning, and soil depth on the change in various soil properties from 2010 to 2020 in a long-term ...


Comparative Analysis Of Azo Dye Restriction In The International Textile Industry, Kayla DeMark 2021 University of Arkansas, Fayetteville

Comparative Analysis Of Azo Dye Restriction In The International Textile Industry, Kayla Demark

Apparel Merchandising and Product Development Undergraduate Honors Theses

Azo dyes are the most used type of dye in the textile industry. Some of these dyes have the potential to be extremely toxic to both human health and the environment. While regulations of these dyes vary across the world, it is suggested that not enough is being done to protect consumers and the environment from potentially harmful azo dyes (Rawat et al., 2016). It is the responsibility of apparel companies to ensure that their products that contain azo dyes are safe for consumers.

The purpose of this study was to understand how azo dyes and their by-products are restricted ...


A Comparison Of The Environmental Effects Of Renewable And Non-Renewable Energies, Jordan Moore 2021 University of Arkansas, Fayetteville

A Comparison Of The Environmental Effects Of Renewable And Non-Renewable Energies, Jordan Moore

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

This study presents current energy data from the United States and data from literature reviews to create life cycle assessments (LCA) for comparing the environmental impacts of wind and coal-fired energy generation and use. The environmental impacts were evaluated using emissions data, principally carbon dioxide emissions and carbon dioxide equivalents from methane. Other environmental impacts such as avian mortality and land use were compared as well. The LCA includes four phases: raw materials, transportation, use/retail, and waste. Overall, wind energy has a smaller environmental impact than coal-fired energy for the raw materials, transportation, use/retail, and waste phases. Wind ...


Economic Feasibility Of Mixed Plastic Waste Pyrolysis Using Twin Reactor System In Northwest Arkansas, Carol Rogers, Patricia Means, Renato Gonzalez, Kaida Sheets, Hayden Townsend 2021 University of Arkansas, Fayetteville

Economic Feasibility Of Mixed Plastic Waste Pyrolysis Using Twin Reactor System In Northwest Arkansas, Carol Rogers, Patricia Means, Renato Gonzalez, Kaida Sheets, Hayden Townsend

Chemical Engineering Undergraduate Honors Theses

Plastic waste generation is increasing at an unsustainable rate while recycling solutions remain stagnant. As a chemical means of recycling, mixed plastic waste pyrolysis can generate synthetic oil appropriate for use as fuel in power generation from plastic waste that otherwise accumulates in landfills. With the scaling of a commercial plastic pyrolysis process in Northwest Arkansas (NWA) modeled after an operational sawdust pyrolysis unit in Huntsville, Arkansas, economic analysis resulted in 26.3% internal rate of return. Therefore, construction of a commercial mixed plastic-to-fuel pyrolysis plant is economically justified and should be pursued. To effectively implement the proposed design, NWA ...


Estimating Irrigation In Rice Fields With A Water Balance Approach, Kristen Trinh 2021 University of Arkansas, Fayetteville

Estimating Irrigation In Rice Fields With A Water Balance Approach, Kristen Trinh

Biological and Agricultural Engineering Undergraduate Honors Theses

Global food production must increase to meet the demand associated with increased population growth, so irrigation water use will continue to rise. Therefore, it is important to monitor water usage particularly when an irrigation flowmeter is unavailable. A field water balance was created for a selection of rice fields in East-central Arkansas under observation in 2018 and 2019. From those, irrigation inputs are deduced from the water balance alone. First, each field had sensors that collected water table level (WTL) data. Next, other water inputs and outputs such as precipitation and evapotranspiration (ET) were collected from two modeled sources. The ...


Low Impact Development: Low-Maintenance Design To Encourage Residential Adoption Of Sustainable Systems, Haley Ellis 2021 University of Arkansas, Fayetteville

Low Impact Development: Low-Maintenance Design To Encourage Residential Adoption Of Sustainable Systems, Haley Ellis

Biological and Agricultural Engineering Undergraduate Honors Theses

Residential adoption of low-impact development (LID) technology can positively impact downstream watershed hydrology by reducing total volumetric discharge from the residential site. This reduction can provide economic, environmental, and social benefits for the residents as well as the community at large. Additionally, homeowners are often affected by stormwater related issues, like flooding or washout, that could be easily mitigated with a sustainably engineered LID structure or network. Engineering for sustainability often includes the blending of several objectives to provide greater overall benefit. This thesis compares the outflow characteristics of three low-maintenance residential LID design scenarios differing in rain garden soil ...


The Bridge To Closing The Green Gap, Samantha Rife 2021 University of Arkansas, Fayetteville

The Bridge To Closing The Green Gap, Samantha Rife

Marketing Undergraduate Honors Theses

In today’s society, we have seen the theme of green consciousness and sustainability become more prevalent as the years pass by. Even as this concept seems to increase in consumer engagement there is not a proportional increase in consumer behavior. This is what is referred to as the gap between green consciousness and green consumerism. Many believe the root of this issue can be solved by increasing regulations. However, I believe this gap can be narrowed by using brands to shift consumers behaviors through their message. The main question that I want to focus in on is, “Can a ...

Improving Logistics Efficiency Through Collaborative Truck Routing, Patrick Dougherty

Industrial Engineering Undergraduate Honors Theses

The logistics industry is among the world’s largest and most essential. Specifically, trucking is a massive component of the modern logistics system. In 2012, truck transportation carried 68% of all freight tonnage in the U.S. However, trucking currently faces significant problems with efficiency and sustainability. Of all miles driven by trucks yearly in the U.S., 25% are driven with empty loads and 36% are driven with underutilized loads. In addition to this economic inefficiency, the industry faces social and environmental challenges. Driver turnover rates are near 100%, and trucking accounts for a significant level of greenhouse gas ...


Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank 2021 University of Southern Maine

Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank

Thinking Matters Symposium

In the United States, the legal framework for product date labeling is minimal and varies across states. Manufacturers have the discretion to use any date label that they deem appropriate, and this lack of uniformity leaves room for misinterpretation by both retailers and consumers. Previous studies have examined consumer misinterpretation of date labels and how this lack of knowledge correlates to food waste behaviors. This study was aimed at understanding how consumers apply their knowledge about date labels to make decisions about purchasing and discarding food. The research was conducted via an intercept survey outside of a grocery store to ...

041— Fiber Decomposition And Pretreatment Analysis Of Cannabis Sativa L.: Hemp, Dina Bu, Jessica Roggie, Sarah Schmidlin, Barnabas Gikonyo

GREAT Day

Hemp is a subspecies of Cannabis sativa L. along with marijuana, yet the two differ in chemical constituent levels of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). Hemp contains 0.3% THC, compared to marijuana 17.1%, allowing it to be a safe and compelling biomass for investigation. The refined products of hemp are vast due to its fast-growing properties; therefore various commercial industries have included refined hemp in biofuels, biodegradable plastics, textiles, dietary supplements, paper, clothing, and much more. Construction and manufacturing applications have also been seen to include hemp to strengthen their composite products. The high-yielding, sustainable, and environmentally friendly ...

Biochar-Swine Manure Impact On Soil Nutrients And Carbon Under Controlled Leaching Experiment Using A Midwestern Mollisols, Chumki Banik, Jacek A. Koziel, Mriganka De, Darcy Bonds, Baitong Chen, Asheesh K. Singh, Mark A. Licht

Agricultural and Biosystems Engineering Publications

Biochar application to the soil can improve soil quality and nutrient leaching loss from swine manure adapted soils. Our working hypothesis was that the biochar-incubated with manure could be a better soil amendment than conventional manure application. The manure-biochar application to the soil would decrease nutrient leaching from manure and increase plant-available nutrients. The study objectives were to 1) assess the physicochemical properties of the manure-biochar mixture after lab incubation and 2) evaluate the impact of biochar-treated swine manure on soil total C, N, and other major and minor nutrients in comparison to conventional manure application to soil. Three biochars ...

Fair Trade: The Successes And Failures As Seen Through The Sustainable Development Goals, P. Alison Macbeth 2021 Rhode Island College

Fair Trade: The Successes And Failures As Seen Through The Sustainable Development Goals, P. Alison Macbeth

Honors Projects Overview

In this paper I seek to understand fair trade as a social movement and the relationship of fair trade to the 17 Sustainable Development Goals created by the United Nations. I look at the history of the fair trade movement in the context of alternative trade organizations and the sustainability movement during the precipitous rise and stature of nongovernmental organizations (NGOs) in the 1990s. I analyze the growth and scalability of fair trade in the U.S. since 2015 through three of the 17 Sustainable Development Goals: SDG 1: Ending Poverty; SDG 5: Gender Equality; and SDG 12: Responsible Consumption ...


Assessing The Impacts To Society Associated With The Use Of Alternative Ammunition For Hunting On National Wildlife Refuges, Christopher Cahill 2021 University of Massachusetts Amherst

Assessing The Impacts To Society Associated With The Use Of Alternative Ammunition For Hunting On National Wildlife Refuges, Christopher Cahill

Masters Theses

Attempts to eliminate lead ammunition use for hunting through regulatory approaches can be controversial and contentious, despite extensive scientific evidence of the detrimental effect of lead on wildlife species. In the United States, voluntary approaches to non-lead use that have used outreach and education in place of regulatory approaches have achieved sustained behavioral change in hunter ammunition choice. However, voluntary approaches to alternative ammunition use can be confronted with both practical and social barriers. In collaboration with U.S. Fish and Wildlife Service and U.S. Geological Survey Cooperative Research Units Program, this study assessed the practical and social barriers ...
