interests are in the areas of environmentally-conscious chemical
process design, life-cycle assessment, environmental transport
processes, and bioengineering.
Environmentally-Conscious
Design of Chemical Processes
Continued
economic growth and expansion of industrial activity will adversely
affect human health and environmental quality unless impacts are
reduced at the source of waste generation, that is within industrial
processes themselves. Environmentally-conscious design is the
integration of environmental concerns into the design and operation
of industrial processes, with the goal of minimizing the generation
(and also the hazardous characteristics) of the manufactured products
and of byproducts of industrial activity. With the support of
the National Science Foundation, the US Environmental Protection
Agency, and private industry, research is being conducted in the
following areas: i) methods of assessing environmental impacts
of industrial processes, ii) optimization of chemical process
flowsheets to minimize impacts and maximize profits, and iii)
the development of design guidance based on environmental assessments.

Life
Cycle Assessment/Sustainability
Life
Cycle Assessment (LCA) is a method that allows for a comprehensive
assessment of environmental impacts for a product or process. The
scope of the assessment is over the entire life cycle; starting
with extraction of raw materials from the environment, manufacturing,
transportation, use in society, recycle, reuse, and final treatment
or disposal in the environment. Mulitple indicators of environmental
impacts are used; for example air quality issues, water emissions,
solid waste, and resource consumption. The purpose of LCA
is to compare alternative products or processes that meet the same
function. An example might be alternative fuels to meet a
specific transportation requirement (conventional gasoline versus
ethanol). Studies conducted thus far include a comparison of regional
cellulosic feedstocks for ethanol production and alternative beneficial
uses for industrial hazardous wastes and household waste (alternatives
to landfill).

Environmental Transport Processes
Transport processes are important in many environmental
applications. An understanding of transport processes is critical
for predicting pollutant dispersion in the environment and in
the design of some in-situ waste treatment processes. Research
projects involve diffusion of volatile organic compounds in soils,
atmospheric dispersion, emission estimation from area sources
using inverse modeling, and microorganism transport in groundwater.
A large-scale aquifer simulator apparatus is available for
complex transport and remediation studies (Subsurface Remediation
Laboratory).

Bioengineering
A current project is investigating the use of in-vitro mammalian cell bioassays as indicators of exposure
and toxic effects of hazardous chemicals. The in-vitro methods
in our study utilize bioluminescense (catalyzed by the enzyme
luciferase) as a biomarker for cell health status (intracellular
ATP level). In the presence of increasing concentration
of a toxic chemical, ATP levels within the cell drop. An
improved luciferase that is not inhibited by the test chemical
is the objective of this work. In-vitro methods can reduce reliance
on animal studies for determining toxicological properties of
High Production Volume chemicals.

Chemical
Engineering Curriculum Development
Curriculum development projects have focussed
on environmental applications, especially Green Engineering and
Sustainability, and in biochemical engineering. Green Engineering
is the development and commercialization of industrial processes
that are economically feasible and reduce the risk to human health
and the environment. Recent efforts in Green Engineering involve
a textbook and national/regional workshops for educating engineering
faculty on these emerging design and computational tools.
