Dr. Stephanie Lansing



Environmental Science & Technology 1429 Animal Science/Agricultural Engineering Building College Park, Maryland 20742

Dr. Stephanie Lansing leads the Bioenergy and Bioprocessing Lab at the nexus of renewable energy, water quality, waste treatment, and human health, and is committed to understanding the ecological, engineering, and social systems that influence these intertwined areas. Dr.Lansing  serves as a Vice Chair of the Maryland Food System Resiliency Council. Her research focuses on strengthening the biocircular economy, anaerobic digestion, bioplastic formation from waste, and nutrient management. She has 20 years of experience in renewable energy research, extension education, and conducting sustainability life cycle assessments of waste to energy systems. Her work in bioenergy spans from large to small-scale anaerobic digestion in the US, Africa, and Latin America.

Research Areas

Food Waste

Dr. Lansing is leading two new grants totaling >$6 million from the U.S. Department of Energy (DOE) to develop sustainable products, such as biofuels and bioplastics from food waste. These grants are aimed at understanding the waste sources we have, particularly the quantities of food waste, and determining what opportunities exist for us to create renewable resources and energy from that waste. One grant is focused on the production of bioplastics from food waste, while the other is focused on characterizing the municipal solid waste stream to create biofuels that can replace liquid fuels like aviation fuel.

Anaerobic Digestion

Anaerobic digestion is a technology that transforms waste into renewable energy while reducing greenhouse gas emissions. During anaerobic digestion, biogas is produced from a natural consortium of microbes that break down biodegradable material inside a sealed, oxygen-free reactor. Anaerobic digesters can use a wide range of waste, such as food scraps, manure, crop waste, or sewage sludge. 

Topics include:

  • Bioenergy and waste treatment to reduce odors, greenhouse gas emissions, and create beneficial fertilizers
  • Waste to Energy Research: Anaerobic digestion, microbial fuel cells, gasification, and solid-oxide fuel cells
  • Small-scale digesters for the US and developing countries
  • High temperature and high pressure anaerobic digestion
  • Effects of nanoparticles on anaerobic digestion and post-digestion utilization
  • Life cycle assessments (LCA) and greenhouse gas accounting of waste to energy and waste diversion

NourishNet - Food Recovery Toolbox

Logo for the NourishNet Project

In the US, 34 million people are food insecure. Yet a third of the food produced in the US is wasted. Our integrated team, NourishNet, funded by that National Science Foundation, offers a cutting-edge toolbox that enhances food security and reduces food waste by putting healthy food in the hands of the food insecure. Our tools include the complete integration of a real-time software app, named FoodLoops, to optimize surplus food distribution with an electronic sensor, named Quantum Nose, to detect early-stage food spoilage. The FoodLoops platform incorporates consumer education, connects small farmers within the food ecosystem, and provides greenhouse gas emission data to allow for data-driven decision-making on food system resiliency. The collaborative NourishNet team includes University of Maryland researchers and entrepreneurs, Prince George’s County Food Equity Council, ChowMatch, LindaBen Foundation, SCS Engineers, and Well Said Media.

Our tools will strengthen food system resiliency by promoting equitable donations and redistribution of nutritious surplus food. Our real-time data collection and modeling will empower government agencies and institutions to strategically invest in waste prevention, food diversion, anaerobic digestion, composting, and climate-smart infrastructure for local food markets. The nationwide deployment of FoodLoops and Quantum Nose will increase equity, connect key food system stakeholders, empower underserved populations, create new educational resources, and allow for real-time forecasting and data-driven decision-making.

Food Energy Water Nexus

Food, water, and energy systems are intimately connected. Water and nutrients are needed to grow crops and feed animals. Agricultural runoff can degrade water quality and increase eutrophication, while energy is integral to both agricultural production and water treatment. The connection between these systems is known as the Food-Energy-Water (FEW) Nexus.

Topics include:

  • Recovering nutrients from waste using post-nutrient extraction after anaerobic digestion
  • Nutrient recovery from Chesapeake Bay using algal turf scrubber (ATS) with anaerobic digestion of algae feedstocks to drive a fuel cell at the Port of Baltimore
  • Food waste, dairy and poultry manure digestion in Maryland, as well as sanitary waste digestion in Haiti

Antimicrobial Resistance

Antimicrobial resistance is of increasing concern, with antibiotics use in agriculture and public health settings leading to an increase in bacterial resistance in the environment.

Topics Include:

  • Antimicrobial resistance, persistence and treatment in dairy and beef manure waste management processing and the wastewater industry

Graduate Students

Danielle Delp

Algal Digestion and Watershed Management 




Danielle is a doctoral student researching anaerobic digestion of algae in the department of environmental science and technology department. Her interests lie in the application of algal biotechnology for use in bioremediation and bioenergy production. She currently works with algal turf scrubber systems to grow algae on water drawn from tributaries of the Chesapeake Bay to produce a feedstock for methane production via anaerobic digestion. This combined technology presents a potential method for carbon-neutral bioenergy production while providing continuous remediation to impacted waterways.

Carlton Poindexter

Antimicrobial Resistance and Manure Treatment




Carlton Poindexter is an NSF-NRT doctoral student in the department of environmental science and technology at the University of Maryland . His research is focused on environmental antimicrobial resistance and the effectiveness of anaerobic digestion and other waste/ wastewater treatment technology. This research seeks to determine ecological mechanisms involved in the occurrence and transmission of antibiotic resistant genes and antibiotic resistant bacteria.

Usoshi Chatterjee

Waste Conversion and Systems Engineering 




Usoshi is a doctoral student in the department of Environmental Science and Technology at University of Maryland. She has a Master's and BS from Ohio State University in Food and Biological Engineering and is interested in learning various ways to incorporate sustainable systems. Her doctoral research focuses on conversion of waste into soil amendments for plants and potential use of carbon sequestration and pollution abatement, as well as analyzing the life cycle of a system. This proposed research is to develop innovative bioenergy/processing technologies to increase agricultural productivity.
