Sustainable Chemical Processes
Chemical processes have been a cornerstone of industrial revolution and societal progress. The development of sustainable chemical processes using green chemistry concepts can potentially minimize resource use and environmental impacts.
Biofuels and environmental engineering laboratories have been developed to support innovative sustainable chemical processes by using green solvents and restricting the use of highly toxic and corrosive chemicals. Our objectives are to develop new chemical and environmental processes and products using a system approach that results in zero waste, high energy efficiency, zero toxicity, and minimal impact over life cycle.
The current research focuses on
-
Application of sub- and supercritical water (hydrothermal) technology for the conversion of biomass/algae to advanced biofuels, biochar, hydrochar, and bioproducts.
-
Supercritical fluids (CO2 and water) based green and sustainable processes.
-
Environmental chemical engineering, environmental catalysis, wastewater, and nutrients management.
- Thermochemical conversion processes and high temperature/high pressure reactions.

Unconventional Energy Governance
Producing unconventional energies has a long history dating back to the 1940s but recent advances in hydraulic fracturing (fracking) and horizontal drilling have made these energies competitive in the global market.
Producing unconventional energies carries a variety of known and unknown environmental and societal risks; interdependency of energy markets, global economy, environmental policies, emerging technology/innovation management, societal concerns and most importantly unknown aspects of these types of new technologies have made decision making and policy design of unconventional energies a very complex area which requires research.

- Unconventional energy systems risk analysis to meet associated environmental, economic and sociopolitical challenges.
- Unconventional energy critical infrastructure management.
- Energy technology innovation management and underlying policy analysis through system of systems engineering approach.
- Decision support system design to enable decision making in both industry and government sector.

Nutrient Cycling in Bio-Energy Systems
Dr. Ben Stuart's current research project is assessing the potential of utilizing anaerobic digestion (AD) in the management of liquid and solid waste streams from houses and residential communities. Subsequent algal cultivation from the disinfected liquor from the AD process will provide opportunities for food/crop production, as well as serving as a feedstock for processing into other value-add products. The waste streams and cultivated biomass will also be processed into biofuels (e.g. biogas, bidiesel) that will significantly contribute to the energy requirements of the house/community, and co-products will be incorporated into recycle streams to improve overall process efficiencies and to meet additional resource demands (e.g. clean water, food production). Including water and waste management with the potential for food production and generation of biofuels will augment existing off-grid power technologies (e.g. solar PV, solar thermal, wind) that provide many homeowners with desired energy security, and will extend the sustainability and resource independence of residential communities. Results to date include food waste characterization (proximate and ultimate analysis), biochemical methane potentials, disinfection optimization of the AD liquor, algal strain selection, and optimization of algal growth as a function of the form of nitrogen delivered. These initial investigations have informed a materials and energy flows demand analysis assessing the potential for realistic implementation. Initial modeling of the AD processes has also identified critical control variables for optimized digester operations.
