Optimizing Anaerobic Digestion Of Food Waste And Industrial Sludge For Biogas Production, Emma R. Murray
Optimizing Anaerobic Digestion Of Food Waste And Industrial Sludge For Biogas Production, Emma R. Murray
Honors College Theses
Food waste is a major contributor to municipal solid waste, and its disposal at landfills has significant environmental and economic impacts. Opportunities need to be identified for the sustainable management of food waste at large scales. Pulp and paper mills throughout the country commonly use anaerobic digestion to treat their waste sludge; however, this sludge can consist of over 50% lignin, which is slowly or negligibly digested. This research aims to explore the sustainability of co-digestion of food waste and paper mill sludge. Lab-scale studies were used to assess the feasibility of anaerobic digestion by measuring treatment efficiencies and biogas …

The objectives for this research project are to explore options for innovative and sustainable materials in lightweight concrete. Various materials including granite powder, hydrated lime, latex, and recycled glass beads will be used in the concrete testing for this project. The question the team wants to answer is how these additives affect the concrete’s mechanical properties. Weekly mix designs will be performed, and control cylinders will be compared to experimental cylinders. Compression and tensile testing will also be performed to further aid the research. The motivation for performing this research is to aid mix development for the University of Akron …
