Stop Filling the World with Trash: A Study of Circular Waste Management Strategies in NYC

This thesis seeks to understand the impacts and ramifications of solid waste generation and waste management strategies in New York City. It is concerned with the relationship between solid waste and the mass production and mass consumption patterns associated with the take-make-waste industrial economic model. Additionally, the investigation examines the circular economy as an alternative to take-make-waste. Special attention is given to the environmental and societal implications of continuing in the current linear industrial system and the urgency to move towards a circular economy. “Stop Filling the World with Trash: A Study of Circular Waste Management Strategies in NYC” addresses the following questions: what are the current municipal solid waste management strategies? Where does the solid waste go post-collection and how is it transported? What policies are being considered to address the negative externalities related to solid waste and Waste Management? What role can the circular economy play in minimizing the negative environmental and societal impacts of waste management? What are the implications of adopting a circular economy? Does moving to a circular economy require changes to the regulatory framework? The findings suggest that shifting to a circular or sustainable economic model is urgent. If we continue in the linear system of mass production and mass consumption, the negative effects to people and the environment may become irreversible. However, making this paradigm shift will entail a concerted effort among the public and private sectors, and civil society

Blood Banking in Living Droplets

Blood banking has a broad public health impact influencing millions of lives daily. It could potentially benefit from emerging biopreservation technologies. However, although vitrification has shown advantages over traditional cryopreservation techniques, it has not been incorporated into transfusion medicine mainly due to throughput challenges. Here, we present a scalable method that can vitrify red blood cells in microdroplets. This approach enables the vitrification of large volumes of blood in a short amount of time, and makes it a viable and scalable biotechnology tool for blood cryopreservation.National Institutes of Health (U.S.) (NIH R21 EB007707)Wallace H.

Living Bacterial Sacrificial Porogens to Engineer Decellularized Porous Scaffolds

Decellularization and cellularization of organs have emerged as disruptive methods in tissue engineering and regenerative medicine. Porous hydrogel scaffolds have widespread applications in tissue engineering, regenerative medicine and drug discovery as viable tissue mimics. However, the existing hydrogel fabrication techniques suffer from limited control over pore interconnectivity, density and size, which leads to inefficient nutrient and oxygen transport to cells embedded in the scaffolds. Here, we demonstrated an innovative approach to develop a new platform for tissue engineered constructs using live bacteria as sacrificial porogens. E.coli were patterned and cultured in an interconnected three-dimensional (3D) hydrogel network. The growing bacteria created interconnected micropores and microchannels. Then, the scafold was decellularized, and bacteria were eliminated from the scaffold through lysing and washing steps. This 3D porous network method combined with bioprinting has the potential to be broadly applicable and compatible with tissue specific applications allowing seeding of stem cells and other cell types
