Reducing food waste is widely recognized as critical for improving resource efficiency and meeting the nutritional demand of a growing human population. Here we explore whether the sharing economy can provide meaningful assistance to reducing food waste in a relatively low-impact and environmentally-sound way. Analyzing 170,000 postings on a popular peer-to-peer food-sharing app, we find that over 19 months, 90t of food waste with an equivalent retail value of £0.7 million were collected by secondary consumers and diverted from disposal. An environmental analysis focused on Greater London reveals that these exchanges were responsible for avoiding emission of 87–156t of CO2eq. Our results indicate that most exchanges were among users associated with lower income yet higher levels of education. These findings, together with the high collection rates (60% on average) suggest that the sharing economy may offer powerful means for improving resource efficiency and reducing food waste.

The article documents the emergence of a food-waste-based commodity frontier in the United States that completes a process of food commodification from cradle to grave. Evidence is drawn from two contemporary trends: the introduction of a profit motive into surplus food rescue activities and the development of new municipal curbside composting programs. The language and theory of commodity frontiers are used to explore observed patterns and inform potential future evolution of each trend. The article contributes to the development of a theory of waste-based commodity frontiers in highly-formalized and well-capitalized contexts like the United States.

Africa is currently experiencing rapid population growth and accelerated urbanization. This demographic shift will require a large amount of new construction material resulting in substantial environmental impact. For many cities on the continent, data gaps make specific quantification and robust prediction of this impact highly difficult. This article presents a method to assess the stock dynamics and embodied emissions of a rapidly growing urban built environment using a bottom-up, typological approach. This approach allows for the identification of appropriate engineering solutions for decarbonization by localizing embodied greenhouse gas (GHG) emissions in the different constructive elements with a revisited Sankey diagram. Different alternatives regarding housing type and construction techniques are compared. The city of Johannesburg is used as a case study to illustrate the relation between building types, technologies, and embodied GHG of its residential building stock. This new visualization uncovers the most material- and GHG-intense dwelling types and building elements. The adapted Sankey represents the building stock and its drivers in a simple way, allowing clear understanding of the consequences of potential alternatives. The business-as-usual scenario indicates 100.5 megatons carbon dioxide equivalent (Mt CO2-eq) for new construction between 2011 and 2040. The results of the dynamic model over time show that only a combination of a densified building stock with multistory buildings and the use of alternative construction materials and techniques show real potential to decelerate GHG emissions (33.0 Mt CO2-eq until 2040) while aiming to provide adequate and sustainable housing for all.

The Casella-Hypertherm Recycling Partnership (CHRP) is a collaboration between a waste management company and a manufacturer that has created a unique recycling environment for companies in the Upper Valley region of Vermont and New Hampshire. This article presents the CHRP as a novel form of industrial symbiosis (IS) using the recently published theoretical framework of IS dynamics proposed by Boons et al. We present this partnership in the academic literature for the first time and also gauge the adequacy of the typology when faced with a new model of IS. We argue that the CHRP exhibits qualities of multiple dynamics, and may in fact be an example of a new dynamic which we call “active facilitation”. Finally, the article also contributes evidence to the Boons et al. generative research question about the relationship between initial conditions and specific dynamics by analyzing the context in which the CHRP emerged.

The process of urbanization is one that is inextricably linked with the consumption of material, energy, and water resources. Urban metabolism provides a framework for characterizing the magnitudes of these urban resource requirements by considering the extended analogy of the biological metabolic process. In this study we propose a System Dynamics approach for linking the stocks and flows of urban metabolism with the socioeconomic activities of cities. We also present initial results from its application to the island city-state of Singapore. In the long term, we intend this technique of dynamic urban metabolism to be both descriptive and predictive, the former to better understand different historical modes of urban resource consumption, and the latter to inform strategies for resource efficient urban development in an increasingly resource-scarce world.

In this study we connect life styles and spending patterns to environmental impacts and economic implications for people living in the United States. The results show that even the most modest life styles (Buddhist monk, homeless etc) have impacts much larger that the world average.
