Shaping Resource Flows

Rethinking Our Resource Management

Resources and their flows are vital for sustaining the well-being and prosperity of society. These resources are finite, and their distribution across the planet and its communities is uneven.

The imbalance in resource flows is widely believed to be a root contributor to global warming. Fortunately, the global and regional systems that civil and environmental engineers envision, design and build are ideally positioned to alter the flow of resources to create more sustainable habitats. We are reimagining how to manage resources, implement new scientific approaches, design innovations, develop business models and create more equitable access to resources in ways that disrupt the modus operandi. In this way, the efforts of civil and environmental engineers will create efficient resource utilization and sustainable resource management.

We are rapidly moving from a single-use mindset to a circular mindset around use and management of resources. Materials previously classified as waste, such as municipal and industrial waste, can be safely repurposed for use by other sectors of the economy or other communities.

New approaches to capturing and managing all sources of fresh water, such as urban stormwater, can combat water scarcity and provide greater water security. Rich nutrients can be extracted from urine and used to produce fertilizers for food production. Carbon dioxide emitted by industrial processes, including in the creation of infrastructure materials, can be collected and sequestered in built infrastructure.

Novel approaches to managing resource flows require new ways of thinking and interacting with stakeholders and society, who are the ultimate managers, consumers and also producers of resources. We are using the principles of co-design and community engagement to share knowledge in ways that result in user engagement and conservation-minded behavior.

What does it mean to shape resource flows?

Associate Professor Krista Wigginton discusses how civil and environmental engineers can shape resource flows to create a more sustainable future.

  • 200 billion

    In 2015, 200 billion gallons of stormwater went down the drain in California, enough to supply 1.4 million households for a year.

  • $300 billion

    In the next 10 years, U.S. local governments will spend over $300 billion to replace 1.6 million miles of aging water infrastructure.

  • 16 kilos

    On average, everyone uses 16 kilos of resources extracted from earth every day—metal, fossil energy and minerals. If you live in the western world, this number is much higher—up to 57 kilos of newly-mined minerals per day.

Our Approach

Our strategic directions have a broad impact on the way we operate, influencing our approach to research, education and outreach. Explore some examples of how we are implementing the concept of Shaping Resource Flows across our department.

Research

  1. A person stands in front of a bathroom stall, gesturing towards an infographic on the door.

    Peecycling

    Like many other human wastes, source-separated urine is rich in valuable resources, namely nitrogen and phosphorus. Our researchers are developing new technologies to collect urine and convert it into fertilizer. We also seek to understand and address the infrastructure and societal barriers to capturing nutrients from urine.

  2. Ocean waves crash and spray against wavebreakers.

    Making Waves

    Ocean wave energy constitutes a tremendous, untapped resource for utility-scale power in the United States. However, the development of devices to harness this resource is an enormous challenge. Not only must such devices be able to survive the harsh conditions encountered during storms and hurricanes, but they must also be equipped with sophisticated control systems that maximize the amount of energy they harvest from random waves. At the University of Michigan, researchers are collaborating with a number of commercial wave energy device developers to better understand control system design for these devices and to maximize energy output.

  3. A person in a lab coat and safety gear stands in front of a large rack of testing equipment.

    Resource Cycles

    The way we harvest and leverage resources is constrained by how we initiate the infrastructure design process; it is influenced by “the way things have always been done.” We are re-envisioning the value of wastewater, stormwater, solid waste and even waves as resources by exploring disruptive and transformative approaches to achieve efficiencies in resource harvesting. Here, a University of Michigan researcher works with a system that achieves resource recovery through energy offsets, enabled by sensor-mediated control.

  4. A piece of concrete is placed into a dark tube by a person wearing protective gloves.

    Lock It Down

    University of Michigan researchers are finding ways to sequester carbon in manmade materials, such as engineered cementitious composites or “bendable concrete” as shown here. The resulting product not only locks away carbon that would otherwise enter the atmosphere, but also has mechanical properties that may be superior to traditional concrete.

Education

Undergraduate and Graduate Courses

Courses such as “Advanced Fiber Reinforced Concrete for Sustainable Infrastructure,” “Subsurface Energy Systems” and “Materials Selection for Sustainable Design” introduce students to a cyclical view of resources for more sustainable engineering.

Outreach

Engineered Cementitious Composites

The Center for Low Carbon Built Environment (CLCBE) seeks to cut the built environment’s carbon footprint by 50% by 2030. With partnerships across the value chain of building and infrastructure, the center is creating a new circular economy around climate change adaptation and mitigation.

Outreach to the U-M President’s Commission on Carbon Neutrality

Our outreach efforts include working with the President’s office to assist U-M in reaching its goal of achieving carbon neutrality through carbon sequestration, reduced emissions, energy sourcing, policy change and technology development.
