The new edited volume Thinking with Soils – edited by Juan Francisco Salazar, Céline Granjou, Matthew Kearnes, Anna Krzywoszynska, and Manuel Tironi – is now available. You can download a pre-print version of my chapter here, which examines the use of biosolids (i.e. treated sanitation waste) as part of a broader trend to “close the loop” in contemporary agricultural management. The chapter is part of a larger ethnographic research project in which I’m bringing together insights from wastewater treatment experts, soil scientists, and farmers to understand both the productive possibilities and potential pitfalls of using treated sanitation waste on agricultural landscapes in the US (and beyond).
Our zine “Infrastructural Digest” is now completed(!) and 250 copies have just been printed for the opening of the Privy2 demonstration garden. The zine features original artwork and essays by OSU students and faculty that reflect on the history of sanitation and its relationship to agriculture. You can download a copy here.
Our latest article is out, which examines the history and cross-cultural management of human waste (or “night soil”) as an agricultural resource. The paper grew out of a collaborative class project that I proposed to Master’s degree students enrolled in my Environmental Anthropology course in the spring of 2017. Together, we delved into the archaeology and history of night soil use and management, as well as some recent ethnographic research on the subject. This paper synthesizes that work and puts it in conversation with contemporary theorizing of the “metabolic rift” — or the notion that the rise of industrial capitalism led to a fundamental rupture in human relations to the earth’s ecological systems. The article, titled “Night Soil: Origins, Discontinuities, and Opportunities for Bridging the Metabolic Rift,” can be found in the latest issue of the open access journal Ethnobiology Letters.

This summer I’ve been working with students and colleagues in the Knowlton School of Architecture at Ohio State to install a demonstration garden, titled “Privy2: Biosolids and You.” The project is designed to draw attention to the processes by which waste products are transformed into both agricultural and architectural resources. The garden is fertilized with Com-Til — a Class A biosolids product made by the City of Columbus — and planted with corn. The site will also feature an architectural pavilion constructed primarily of material derived from recycled plastics. You can follow our progress and learn more from the project website. You can also read this recent article that provides an overview of the project.
For the past several years, the graduate students of the Ohio State Department of Anthropology have produced A Story of Us, a podcast that is sponsored by the American Anthropological Association. Last semester, Emma Lagan interviewed me about my work as a cultural anthropologist and the episode is now available online. We talked about the early experiences that led me to anthropology and my research in Amazonia as well as my current work that examines how the city of Columbus converts human “waste” into an agricultural resource, known as biosolids. If you have a chance, take a listen. You can also explore earlier seasons from A Story of Us that draw on diverse perspectives and subfields in anthropology to see what they can teach such themes as childhood, migration, and mortality.
If you want to learn about all the fascinating things central Ohio does with its so-called “human waste,” come to this public talk I’ll be giving at Whetstone Library in Columbus on October 27th at 1pm. I’ll discuss how the city is transforming waste into an agricultural resource used to sustain poplar farms on abandoned strip mines, fertilize commodity crops, and produce garden compost, among other things. To conclude, I’ll discuss some of the ongoing obstacles and concerns about expansion of its use in the region. See you there!
In the latest of issue of Edible Columbus, you can find an interview with me discussing the importance of microbial life for soil health, the benefits of night soil for agricultural production, and the need for building local models that can help us to contend with global climate change. Thanks again to Colleen Leonardi for the invitation. You can read it here.
I just published a short blog post for Ohio State’s Initiative for Food and Agricultural Transformation (InFACT), which discusses my new research on the use of biosolids (i.e. treated sanitation sludge) in Midwestern agricultural landscapes.
