Shape Memory Polymers (SMPs) are smart polyurethane thermoplastics that can recover their original shape after undergoing deformation. This shape recovery can be actuated by raising the SMP above its glass transition temperature, Tg. This report outlines a process for repeatedly recycling SMPs using 3D printing. Cubes are printed, broken down into pellets mechanically, and re-extruded into filament. This simulates a recycling iteration that the material would undergo in industry. The samples are recycled 0, 1, 3, and 5 times, then printed into rectangular and dog-bone shapes. These shapes are used to perform dynamic mechanical analysis (DMA) and 3-point bending for shape recovery testing. Samples will also be used for scanning electron microscopy (SEM) to characterize their microstructure.

This proposal lays out the business case for Isagenix International to adopt circular packaging that is compatible with the circular economy. I first give a brief background on plastic packaging and the environmental risks that go along with it. After explaining how a linear economy is unsustainable, I introduce the concept of a circular economy. I then explain the competitive advantages that Isagenix can gain over its competitors from pursuing circular or sustainable packaging, and provide a benchmarking analysis of other companies’ sustainable packaging goals. After establishing the reasons that Isagenix should pursue this initiative, I go into an explanation of how Isagenix should design packaging for circularity and educate consumers on how to recycle their packaging products. Lastly, I propose my three recommendations for action that Isagenix should start with to begin transitioning all of their packaging to be circular.

Tossing Out the Waste: An Exploration of Sustainable Solutions for an Arizona Restaurant

Description

The goal of this project is to gain and use knowledge of sustainability topics as a value-adding function for a business in the Tempe, AZ area and to develop the skills to approach and consult with business owners and staff

The goal of this project is to gain and use knowledge of sustainability topics as a value-adding function for a business in the Tempe, AZ area and to develop the skills to approach and consult with business owners and staff about sustainable business options. Sustainability searches for a balance between society, economy and the environment where all three can thrive; therefore, the ideal project partner was a business that values the wellbeing of mankind, is locally owned and operated and promotes environmental stewardship. The Original Chop Shop Co in Tempe Arizona was appropriately selected. Throughout the duration of our partnership, I observed their daily routine, interviewed employees and managers and used the collected information to identify three areas of focus that have the largest potential to reduce The Original Chop Shop Company's impact on the environment. Information on the areas of recycling, composting, and food sourcing was researched and synthesized to make suggestions for ecofriendly changes to business practices. The scope of the project includes small changes in daily practices such as implementing a recycling and composting program and employee training sessions and minor investments such as purchasing a micro washer and silverware in order to eliminate nonrenewable plastic utensils. The scope does not include major renovations or investments in technology. The suggestions offered position The Original Chop Shop to conduct business in a way that does not compromise the health of the environment, society, or economy.

Waste management within the office represents a major sustainability problem for many corporations. Salt River Project (SRP) faces unique challenges at Coronado Generating Station (CGS) and the employee recreation facility Project Employee Recreation Facility (PERA). Addressing major waste streams at CGS involved shifting perspectives, adapting current infrastructure, and incorporating recycling into employee resources. Composting represented an easy to communicate and effective solution to minimizing waste at the newly remodeled PERA club, where the emphasis of the site is employee training, events, and catering. Employee engagement at both sites was based on the evidence based 6-step approach to implementing sustainable practices, including sparking initial engagement, forming working sustainability teams (Green Teams) and communicating effectively (Russo & Hoffman, 2008). These efforts helped bring sustainable initiatives and efforts to sites that are otherwise overlooked by SRP sustainability and employee engagement efforts. Further, these two sites modeled how sustainable change can be made in existing facilities as well as how sustainability can help model new facility infrastructure and marketing. The project was evaluated based on the Corporate Sustainability Management System framework in order to identify strengths, weaknesses, and areas for improvement.

This project explored the potential effectiveness of sustainable initiative programs in a typical office setting. The project area was focused on the Arizona offices of Expeditors International, a global, Fortune 500, third-party logistics company. The goal of the project was to set up recycling and composting services as well as create a culture of sustainability through educational materials distributed through various means to the employees. Throughout the project, it was discovered that there can be many barriers to effective implementation of sustainable initiatives, such as resistance to change. However, this project also highlighted that with a reasonable amount of effort and a strong logic behind the why, it it possible to shift the behaviors of normal office employees. This project also showed that using small improvements and occasional reminders of the value of being sustainable, behavior can be altered for the better. Despite the obstacles and challenges that are present in every office setting, this project has provided evidence that similar initiatives are very possible and can have a large impact for any company and for the planet.

Contento Recycling: The Evolution of Sustainability

Description

While the term sustainability is commonly used in 2019, in 1950, it was sparsely uttered. To understand how Contento Recycling LLC became Central New York’s leader in sustainable development, you must go back to Gerald Contento Sr, and the year 1950. This was the year my grandfather started our family’s vehicle dismantling and scrap metal recycling business. Over the course of the next 70 years, Contento’s and now, Contento Recycling, has evolved into a leader in recycling and environmental work in Central New York. To see how I created a sustainable business enterprise, you must analyze my family’s past. My family’s history provides a roadmap to a more sustainable future.
When I established Contento Recycling LLC in 2017, it was poised to be Central New York’s first ever construction and demolition debris recycling business. I was tasked with the challenge that many sustainability professionals are tasked with and that was to show the community why they should stop taking their construction debris to the landfill, and instead bring it to my recycling center for processing, recycling, and landfill diversion. Over the last several years I applied for state grant funding, spread awareness about my new business, designed and constructed a material recovery facility, outfitted equipment, and trained staff. I now have a facility that accepts about 40 tons of mixed C&D debris per day, and diverts about 20% of that from the landfill.
On a more personal level, I learned a tremendous amount about dealing with change management. I’ve learned a lot about business development, and some keys to success when building a business. I’ve figured out how to help my employees and customers grow. I’ve learned to be more patient and flexible with my business endeavors. I have a much clearer vision of what I want for my business and for myself. I have developed a rousing optimism on the impact that my business, and myself can have on the sustainable development of Central New York. I will be a leader in environmental stewardship and partner with other people and organizations who want to work towards a more sustainable future.

Currently, recycling is a major issue found throughout the world; however, one of the main issues, small format recycling, is still yet to be solved. The main objective of this paper is to discuss the issues surrounding recycling in general and more specifically small format recycling in order to develop a solution that can solve the problem. Working with InnovationSpace and people in industry, interviews were conducted in order to determine the best course of action to address the need of the sponsor, The Sustainability Consortium. After extensive research and interviews, it was determined that implementing a new MRF attachment to circulate small format back to the main residual stream would be the best course of action. This attachment would be modular for a MRF and could be implemented in order to gather more material while also producing higher quality recycled goods. This has major implications for the recycling industry and could help in making recycling profitable once again.

Circulearning: Ethical Circular Economy Education

Description

Though about 75 percent of American waste is recyclable, only 30 percent of it is actually recycled and less than ten percent of plastics disposed of in the United States in 2015 were recycled. A statistic like this demonstrates the immense need to increase recycling rates in order to move towards cultivating a circular economy and benefiting the environment. With Arizona State University’s (ASU) extensive population of on-campus students and faculty, our team was determined to create a solution that would increase recycling rates. After conducting initial market research, our team incentives or education. We conducted market research through student surveys to determine the level of knowledge of our target audience and barriers to entry for local recycling and composting resources. Further, we gained insight into the medium of recycling and sustainability programs they would be interested in participating in. Overall, the results of our surveys demonstrated that a majority of students were interested in participating in these programs, if they were not already involved, and most students on-campus already had access to these resources. Despite having access to these sustainable practices, we identified a knowledge gap between students and their information on how to properly execute sustainable practices such as composting and recycling. In order to address this audience, our team created Circulearning, an educational program that aims to bridge the gap of knowledge and address immediate concerns regarding circular economy topics. By engaging audiences through our quick, accessible educational modules and teaching them about circular practices, we aim to inspire everyone to implement these practices into their own lives. Though our team began the initiative with a focus on implementing these practices solely to ASU campus, we decided to expand our target audience to implement educational programs at all levels after discovering the interest and need for this resource in our community. Our team is extremely excited that our Circulearning educational modules have been shared with a broad audience including students at Mesa Skyline High School, ASU students, and additional connections outside of ASU. With Circulearning, we will educate and inspire people of all ages to live more sustainably and better the environment in which we live.

Silver Recovery from Silver Fluoride Solution for Solar Module Recycling

Description

As Energy needs grow and photovoltaics expand to meet humanity’s demand for electricity, waste modules will start building up. Tao et. al. propose a recycling process to recover all precious solar cell materials, a process estimated to generate a potential

As Energy needs grow and photovoltaics expand to meet humanity’s demand for electricity, waste modules will start building up. Tao et. al. propose a recycling process to recover all precious solar cell materials, a process estimated to generate a potential $15 billion in revenue by 2050. A key part of this process is metal recovery, and specifically, silver recovery. Silver recovery via electrowinning was studied using a hydrofluoric acid leachate/electrolyte. Bulk electrolysis trials were performed at varied voltages using a silver working electrode, silver pseudo-reference electrode and a graphite counter-electrode. The highest mass recovery achieved was 98.8% which occurred at 0.65 volts. Product purity was below 90% for all trials and coulombic efficiency never reached above 20%. The average energy consumption per gram of reduced silver was 2.16kWh/kg. Bulk electrolysis indicates that parasitic reactions are drawing power from the potentiostat and limiting the mass recovery of the system. In order to develop this process to the practical use stage, parasitic reactions must be eliminated, and product purity and power efficiency must improve. The system should be run in a vacuum environment and the reduction peaks in the cell should be characterized using cyclic voltammetry.
