Accounting For The Environmental Impacts Associated With Residual Products In A Comparative Life Cycle Assessment Of Systems With Multiple Products, Yasuhiro Fukushima, Satoshi Ohara

Journal of Environmental Science and Sustainable Development

In many production systems, multiple products are interactively produced. Therefore, an innovative technology that leads to changes in parts of such systems may influence both the unit environmental impacts associated with the products, and the productivity of multiple products. To compare alternative technologies on a common basis, we often account for the avoided or supplemented emissions associated with the residual (i.e. surplus and supplemented) products produced from within the considered system boundary. In this study, using an example of an innovative technology envisioned for use in sugar mills, we first demonstrate how comparisons can be made when the systems vary …

The Impact Of The Implementation Of Temporary Import Procedure On Electronic Products: Input--Output Analysis, Dedi Abdul Hadi, Toru Matsumoto

Journal of Environmental Science and Sustainable Development

Currently, imported electronic products enter the Indonesian market using general import procedures, where the importer has to pay the import duty and taxes in full rate. In the absence of proper recycling systems, the electronic products that have reached their end of life and those are no longer used, end up in the landfills. Some researchers found hazardous materials inside the electronic products that could contaminate water, soil and air. Therefore, another strategy is needed to avoid negative effects on the environment. The Temporary import policy is one of the import procedures under Customs administration control, which states that goods …

Employee Perceptions Of Organizational Corporate Responsibility And Their Effect On Employee Organizational Commitment, Lisa R. Davis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The debate over whether organizations play a part in society beyond economic profit has been a major focus of research in corporate social responsibility (CSR). These debates have been mainly looked at from the macro (societal) or the meso (institutional) level. Very little research has been done on the role of the firm and looking at CSR from the micro (individual) level. Questions regarding the role of work for employees, securing economic benefits or making a difference in the world, would vary greatly depending on the individual and the importance they place on these areas in their own lives. Scholars …

As The Clothing Industry Is A Major Polluter, Sustainable Fashion Is Rising, Gabe Herman

Capstones

That the fashion industry is one of the biggest polluters in the world is one of the industry’s best-kept secrets — it uses a quarter of the chemicals produced globally, and its share of the world’s CO2 emissions is expected to rise from 2 percent to 26 percent in the next 30 years. Developing nations — where many factories are located — are most affected. Every year in Bangladesh, for example, tanneries dump enough toxic waste into rivers to fill three Olympic-sized swimming pools. Advocates and some in the fashion world are working to not only get the word out, …

Disrupting Desalination: Novel Energy Efficient Technologies For Hypersaline Brines, Ngai Yin Yip

Sustainability Seminar Series

Management and treatment of hypersaline brines, e.g., produced water from oil and gas extraction, zero liquid discharge effluent, and flue gas desulfurization wastewater, are of growing environmental importance. Prevailing practice of distilling brines is highly energy-intensive and costly because the evaporation of water is enthalpically unfavorable. Here, we present two novel technologies for hypersaline desalination: cascading osmotically mediated reverse osmosis (COMRO) and temperature swing solvent extraction (TSSE). The first technology, COMRO, utilizes the novel design of bilateral countercurrent reverse osmosis stages to lessening the osmotic pressure difference across the membrane, thereby simultaneously depressing the hydraulic pressure needed and reducing energy …

Treatment Of Plastic Wastes Using Plasma Gasification Technology, Zachary A. Homolka

Department of Environmental Studies: Undergraduate Student Theses

Plasma gasification (PG) complements traditional recycling when applied to contaminated or

mixed plastics. Without PG these plastics cost recyclers more to process than they are worth on the market, and sometimes they are landfilled or incinerated instead of being recycled. Plasma gasification can take plastic not suitable for traditional recycling and break it down into high-quality syngas for use in electricity generation, chemical manufacturing, or hydrogen production. The technology can be implemented without changing the behavior of consumers, which is a major advantage over attempting to decrease contamination or reduce use of low-value plastic. Due to high capital requirements and …

Factors Perceived By Multifamily Property Owners And Managers As Beneficial In Improving Energy Efficiency, Alex David Arneson

Department of Environmental Studies: Undergraduate Student Theses

Maintaining the existence of affordable housing stock is an important goal for most cities and

communities, as well as at the state and national level. Compared to single-family housing, the multifamily housing sector poses a unique set of challenges and barriers related to investments in energy efficiency. With more than 50 million Americans, many of whom are low income, living in multifamily housing, this sector presents vast opportunities to reduce energy consumption. Reducing our carbon footprint has become an important issue in today’s society. More than ever, there is increased demand to incorporate ‘green’ sustainable design elements and technologies into …

Transition Pathways To Sustainable Agricultural Water Management: A Review Of Integrated Modeling Approaches, Erin M.K. Haacker, Vaishali Sharda, Amanda M. Cano, R. Aaron Hrozencik, Agustin Nunez, Zachary Zambreski, Soheil Nozari, Garvey Engulu B, Smith, Lacey Moore, Sumit Sharma, Prasanna Gowda, Chittaranjan Ray, Meagan Schipanski, Reagan Waskom

Nebraska Water Center: Faculty Publications

Agricultural water management (AWM) is an interdisciplinary concern, cutting across traditional domains such as agronomy, climatology, geology, economics, and sociology. Each of these disciplines has developed numerous process-based and empirical models for AWM. However, models that simulate all major hydrologic, water quality, and crop growth processes in agricultural systems are still lacking. As computers become more powerful, more researchers are choosing to integrate existing models to account for these major processes rather than building new cross-disciplinary models. Model integration carries the hope that, as in a real system, the sum of the model will be greater than the parts. However, …

Keynote: Motivating Private Climate Governance: The Role Of The Efficiency Gap, Michael P. Vandenbergh

Arkansas Law Review

The topic of this symposium, “Environmental Sustainability and Private Governance,” is important and timely. In response to the shrinking federal role in environmental protection, many policy advocates have focused on the role of states and cities, but this symposium focuses on another important source of sustainability initiatives: the private sector, including corporations, households, civic and cultural organizations, religious organizations, private hospitals, colleges and universities, and other organizations. States, cities, and other subnational government responses are increasingly important, but the limited geographic reach of subnational governments constrains their ability to address many environmental problems. For instance, although twenty states have set …

Incentives For Coastal Persistence, Porter Hoagland

Sustainability Seminar Series

Inundation, erosion, and property damages and losses are being observed at increasing rates in coastal areas. It is now well-recognized that rising sea levels, increases in storm intensities, and inadequate structural protections are contributing to the significant physical destruction of and economic losses to coastal properties. Scientists, coastal zone managers, and the general public have begun to call for implementing policies of resilience and adaptation to these losses, including retreating from the coast, yet humans continue to live—and even increase their presence—along the nation’s shorelines. What causes such persistence? It has become commonplace to identify lower-than-actuarially-fair premiums for participation in …

Novel Materials Can Radically Improve Whole-System Environmental Impacts Of Additive Manufacturing, Jeremy Faludi, Cory M. Van Sice, Yuan Shi, Justin Bower, Owen M.K Brooks

Dartmouth Scholarship

Additive manufacturing often has higher environmental impacts per part than traditional manufacturing at scale, but new materials can enable more sustainable 3D printing. This study developed and tested novel materials for paste extrusion printing, and tested materials invented by others. Testing compared their whole-system environmental impacts to standard ABS extrusion, measured by life cycle assessment (LCA); testing also assessed material strength, printability, and cost. Materials were chosen for low print energy (chemical bonding, not melting), low toxicity, and circular life cycle (biodegradable, ideally sourced from waste biomaterial). Printing energy was reduced 75% (from 160 to 40 Wh/part), and embodied impacts …

From The Household To Watershed: A Cross-Scale Analysis Of Residential Intention To Adopt Green Stormwater Infrastructure, Sarah Coleman, Stephanie Hurley, Donna Rizzo, Christopher Koliba, Asim Zia

College of Engineering and Mathematical Sciences Faculty Publications

Improved stormwater management for the protection of water resources requires bottom-up stewardship from landowners, including adoption of Green Stormwater Infrastructure (GSI). We use a statewide survey of Vermont paired with a cross-scale and spatial analysis to evaluate the influence of interacting spatial, social, and physical factors on residential intention to adopt GSI across a complex social-ecological landscape. Specifically, we focus on how three GSI practices, (“rain garden (bio retention),” “infiltration trenches,” and “actively divert roof runoff to a rain barrel/lawn/garden instead of the street/sewer”) vary with barriers to adoption, and household attributes across stormwater contexts from the household to watershed …

Similarity Of Introduced Plant Species To Native Ones Facilitates Naturalization, But Differences Enhance Invasion Success, Jan Divíšek, Milan Chytrý, Brian Beckage, Nicholas J. Gotelli, Zdeňka Lososová, Petr Pyšek, David M. Richardson, Jane Molofsky

College of Arts and Sciences Faculty Publications

The search for traits associated with plant invasiveness has yielded contradictory results, in part because most previous studies have failed to recognize that different traits are important at different stages along the introduction–naturalization–invasion continuum. Here we show that across six different habitat types in temperate Central Europe, naturalized non-invasive species are functionally similar to native species occurring in the same habitat type, but invasive species are different as they occupy the edge of the plant functional trait space represented in each habitat. This pattern was driven mainly by the greater average height of invasive species. These results suggest that the …
