Center for Earth Systems Engineering and Management
A collection of scholarly work published by and supporting the Center for Earth Systems Engineering and Management (CESEM) at Arizona State University.
CESEM focuses on "earth systems engineering and management," providing a basis for understanding, designing, and managing the complex integrated built/human/natural systems that increasingly characterize our planet.
Works in this collection are particularly important in linking engineering, technology, and sustainability, and are increasingly intertwined with the work of ASU's Global Institute of Sustainability (GIOS).

This study analyzes the feasibility of using algae cultivated from wastewater effluent to produce a biodiesel feedstock. The goal was to determine if the energy produced was greater than the operational energy consumed without consideration to constructing the system as well as the emissions and economic value associated with the process. Four scenarios were created; 1) high-lipid, dry extraction, 2) high-lipid, wet extraction, 3) low-lipid, dry extraction and, 4) low-lipid, wet extraction. In all cases the system required more energy than it produced. In high lipid scenarios the energy produced is close to the energy consumed and with minor improvements …
