Sustainable development

Population and density
Membrane (bio)reactors
Sustainable Development
• 2 billion people living
on $2/day need basic
needs to be met
– Maslow’s hierarchy of
needs (air, water, food,
shelter)
• Technology ideas:
– Indoor cook stove, play
pump, climate change
resistant crops, ISSB
Biofuels
• Food plus energy from
crops = use more water
and generate more
polluted runoff
• Treatment of disperse,
nutrient rich, waste
streams  how to
recycle nutrients (esp
phosphorus)
http://www.ecofriend.org/images/ebio_4773.jpg
Obesity Epidemic
• 1 in 3 adults (and
children) are obese
• Costs $5,000/person/yr
• Attributed to poor diet
and lack of exercise
• May also be due to
‘obesogens’
http://www.getamericafit.org/images/american-obesity-trends.gif
Population and Density
• 50% of humanity lives
in cities (80% of USA)
• Opportunities to reduce
impacts through scale
• Danger of sprawl
creating worse impacts
– Urban planning lies
between architectural
engineering and civil
engineering
Membrane (bio)reactors
• Fabrication
(functionality)
• Applications (water,
water, everywhere…)
• Anti fouling

Director
Contingency operating bases produce all waste streams
common to any small municipality but with no pre-existing
infrastructure.
Environmental and Sustainability
Solid Waste
Per soldier waste generation:
in a 2003 study 15.8 #/day and in a 2006 study 18.2 #/day
This shows a 15% increase in all studied waste streams over a 3 year
period between studies.
In March of 2010 long term use of Open Air Burn Pits was halted by
the Under Secretary of Defense.
Unfortunately while the intent of this policy change is laudable, we
currently don’t have the means to provide Innovative Landfill designs,
Waste to Energy Systems, and Water reuse technologies to the
operational army.
More research and development needed to bring technologically
superior but operationally simple systems into the Army to solve these
issues.
Deployable Wastewater
Treatment systems
Soldiers produced about 2 pounds
per day of sewage sludge
Human waste must be treated to
avoid disease causing conditions in
the environment.
Systems must be deployable,
expandable and easy to
operate/maintain.
Our concerns:
1. We need a more responsive process to get
innovative technologies into the operational Army.
2. We need to integrate sustainable systems of systems
into the operational Army Culture.
3. We need to practice better waste management
techniques to reduce, reuse, and recycle wastes to
reduce the need for technical treatment options.

Sustainability and Change Resistance
Sustainability as a Sociotechnical
System Component
• What is Sustainability? No good definition
exists!
• Must consider the human elements as well as
the technical
• What quantitative and qualitative metrics are
most useful in determining sustainability?
• EMSE Faculty: Long, Grasman
Civil Infrastructure Systems
• Cradle to grave logistics
systems
• Capacity modeling
• Energy reduction
• Supply/demand as part of
the supply chain
• EMSE Faculty: Long, Grasman, Cudney, Corns,

Sustainability and the Smart Grid
•
The future smart grid will encompass all
of the following features:
– Flexibility – fulfilling customer’s needs
while responding to changes and
challenges ahead;
– Accessibility – granting connection
access to all network users,
particularly for renewable power
sources and high efficiency local
generation;
– Reliability – assuring and improving
security and quality of supply;
– Economy – providing the best value
through innovation, energy efficient
management, competition, and
regulation.

EMSE Faculty: Long, Corns, Grasman
Alternative Energy Sources
• Supply chain logistics
• Energy performance and
life cycle costing
• Market-based technology
innovation
• Lessons learned from nonrenewable consumption
patterns
• EMSE Faculty: Grasman, Corns, Long
Problem of Change Resistance
• Humans Fear Change
because of:
– Loss of control
– Loss of power
– Loss the familiar
• Many technology-focused
projects fail because
change environment is not
properly managed!

Commissioning
Commissioning is a systematic, forensic approach to quality assurance.
The building commissioning process provides documented confirmation
that building systems function according to criteria set forth in the project
documents to satisfy the owner’s operational needs.
Retro-commissioning
Existing Building Commissioning is a systematic process for investigating,
analyzing, and optimizing the performance of building systems through the
identification and implementation of low/no cost and capital intensive Facility
Improvement Measures and ensuring their continued performance over time.

Carbon Capture and Sequestration
• Reduce the buildup of
greenhouse gases in the
atmosphere
• Worldwide CO2 emissions
from human activity have
increased to annual

Synthetic Fuels
Would allow America to reduce
foreign oil imports by tapping its
own domestic energy resources to
produce fuel for transportation and
national defense
Synthetic fuels are produced from coal,
natural gas or biomass and provide a
clear, clean liquid for use primarily as
diesel or jet fuel
Plug-in Vehicles
Stochastic Resources and Loads
Transportation is almost completely powered
by oil - 60% of which comes from foreign
sources.
Adoption of plug-in hybrids will transfer the

Traditional soil remediation
Traditional groundwater remediation
Current Considerations
In situ vs. ex situ
Sustainable but cost-effective remedial alternatives
Soil Remediation
•Dig and haul is still widely used
•Fast, low tech
•Easy to demonstrate compliance (sampling)
•Immediate removal of source ►►may help groundwater
contamination
•Accepted by state and public
•The down side to dig and haul:
•Process can leave a big carbon footprint
•Generates waste, creates potential future cleanup
•Diesel powered equipment
•May disrupt site operations
•Not precise
Groundwater Remediation
•Pump and Treat:
•Fairly simple process
•Contaminant is being removed from environment
•Maintain hydraulic control
•Still readily accepted by regulators/public
•Downside:
•Costly O&M: utility costs plus labor
•Must deal with water management
•Reach a point where its no longer effective
•Long term process: volume you pump out compared to the amount of
contaminant removed may be small
•Rebound is an issue if system is off
Current Considerations
•Risk Based Corrective Action
•Huge change in how sites are cleaned up
•How clean is clean?
•Maximum extent practicable
•Future land use
•Institutional controls to prevent exposure
•Air Issues
•Vapor Intrusion into buildings = consequence of leaving
residual contamination behind
•Hot issue with regulators – significance may be overrated
•How do you evaluate and mitigate this hazard?
Current Considerations
•In situ vs. ex situ
•Ex situ
•In Situ
•Current technologies
•Biotreament, Chemical treatment
•Thermal
•Soil stabilization
•Downside
•Difficult to control outcome
•Limited by media type
•Difficult to evaluate success
•Can be expensive
•Regulators/public may not readily accept the method
•May require permitting
•May disrupt site operations
Current Considerations
Key to future remediation success =
Sustainable but cost effective methods
•Many are able to develop great ideas but must
be cost effective
•Move towards more “green” technologies
•Better use of resources
•Reuse/reduce/recycle
•Buy in from regulators and the public

Unconventional CO2 Sequestration
– Works for any emission of
carbon dioxide
– Simpler than end of pipe
capture of CO2
– May be most economic and
non-intrusive approach to CO2
sequestration
– Use unconventional
sequestration agents
• Manufacturing slag and residues
• Cement kiln dust
System for carbon capture from air.

Revolutionize Manufacturing
• Fully continuous and
automated operation
– Zero waste
• All co-products

Energy Savings:
- less time and less heating in EAF
- no tapping into colder ladle
- no transport
- no holding

steel temperature (ºF)
– Reduced water use
– Reduce air emissions
– Capture energy
Lean, Mean and Green Steel
(light-weight, high-strength and green steel development)
• Lower density steels
• Higher strength steels
• Recycled content
increasing
• Combination of lower
density & higher strength
= lighter weight parts with
improved performance
– Better gas mileage & safety
Renewable Carbon for Manufacturing
• Manufacturing uses coal/oil
– No good source of C in renewable sources
– What if we developed renewable coke?
Design Based Life Cycle Assessment
• Complex design
must include LCA
