Description
This paper recounts a project journey that was taken to explore how replacing plastics with less harmful materials can drive positive environmental impact. The project examined the scope and impacts of plastic pollution attributable to healthcare delivery and the adverse impacts it has on population health. Identifying potential options to replace plastics was accomplished by obtaining access to one of the world’s leading materials databases. This access enabled identification of several alternative materials with documented uses as plastic replacements. Evidence of successes that have been achieved in replacing plastics with less harmful materials was gathered by conducting interviews with international materials experts and senior executives from several different industries. These examples are combined with the research findings on alternative materials to construct a case that taking action can yield financial benefits while doing less harm to people and the planet. The completed project presents a framework that can be followed in future efforts to replace plastics. While the scope of the project focused on the plastic pollution problem from a healthcare perspective, the framework that was created is portable and can be adapted for use in any organization or industry seeking to replace plastics and drive change to create a healthier future.

Description
Of the many challenges cities face, congestion and air quality are two interrelated issues that despite technological improvements in vehicle emissions standards and engine efficiency, continue to worsen. Of the strategies attempting to reduce automobile dependency, a popular approach adopted by cities is the concept of transit-oriented development (TOD). The strategy aims to better integrate land use and transportation planning, and is often characterized by a mix of land uses, high density, and proximity to quality public transit. While practitioners and academics argue the economic and environmental benefits of TOD, there are several examples along the Valley Metro light rail corridor where the strategy appears to be failing to attract people, businesses, and ultimately transit riders. The purpose of this study is to explore how urban infrastructure characteristics, specifically transportation connectivity, urban design, and land use interact to support light rail ridership. The study utilizes a rendition of sustainability’s triple-bottom-line framework, wherein economic, environmental, and social elements are represented as criteria in the transportation, land use, and urban design analysis of six Valley Metro light rail stations. Each element has supporting criteria that are ranked relative to the other stations under analysis, culminating in overall TOD scores for each station. The number of TOD projects and ridership trends are also compared, and in combination with the evaluation of urban infrastructure elements, the results suggest the importance of transportation connectivity, pedestrian-scale infrastructure, a sense of place, and employment centers for TOD stations to yield high ridership. Findings are analyzed through a sustainability lens resulting in the proposal of strategic solutions for improving TOD planning methods.
