Quantifying the Impact of Circular Economy Applied to the Built Environment: A Study of Construction and Demolition Waste to Identify Leverage Points

The built environment is responsible for a significant portion of global waste generation.

Construction and demolition (C&D) waste requires significant landfill areas and costs

The built environment is responsible for a significant portion of global waste generation.

Construction and demolition (C&D) waste requires significant landfill areas and costs

billions of dollars. New business models that reduce this waste may prove to be financially

beneficial and generally more sustainable. One such model is referred to as the “Circular

Economy” (CE), which promotes the efficient use of materials to minimize waste

generation and raw material consumption. CE is achieved by maximizing the life of

materials and components and by reclaiming the typically wasted value at the end of their

life. This thesis identifies the potential opportunities for using CE in the built environment.

It first calculates the magnitude of C&D waste and its main streams, highlights the top

C&D materials based on weight and value using data from various regions, identifies the

top C&D materials’ current recycling and reuse rates, and finally estimates a potential

financial benefit of $3.7 billion from redirecting C&D waste using the CE concept in the

United States.

The circular economy is viewed as a solution to many of the environmental and social ills that the linear economy has exacerbated. Whether it is through refill solutions or redesigning a cardboard shipping container, fast-moving consumer goods (FMCG) brands are rethinking the way their products are delivered to consumers through business model innovations that promote circularity. The consumer plays the important, often overlooked, role of enabler within circular business models. This study aims to increase broader understanding of what motivates circular consumption of fast-moving consumer goods while analyzing the relationship between motivators and the behaviors required to participate. Semi-structured interviews provide insights from consumers who are currently purchasing household cleansers from brands that operate with a circular business model. Results from this study highlight a group of consumers that are distinguished by their common desire to reduce their personal consumption of plastics. There is clear indication that these consumers are in fact seeking out ways to consume more sustainably. A significant subset of this group expresses concern regarding ingredients used in the products. Health concerns for themselves, their family, or a pet are driving a desire to understand product ingredients. There is evidence to indicate that the concern for personal consumption of plastics is being driven by information distributed via social media and supported by targeted advertisements for brands that address this concern.
