2. What is Green engineering…??
It is Design, commercialization and use of process & products
that are feasible and economical.
While minimizing:
*risk to human health and environment.
*generation of pollution at source.
4. Principles of Green Engineering:
1. Engineer processes and products holistically, use systems
analysis, and integrate environmental impact assessment tools.
2. Conserve and improve natural ecosystems while protecting
human health and well-being
3. Use life-cycle thinking in all engineering activities
4. Ensure that all material and energy inputs and outputs are as
inherently safe and benign as possible
5. Minimize depletion of natural resources
6. Strive to prevent waste
7. Develop and apply engineering solutions, while being cognizant
of local geography, aspirations, and cultures
8. Create engineering solutions beyond current or dominant
technologies; improve, innovate and invent (technologies) to
achieve sustainability
9. Actively engage communities and stakeholders in development
of engineering solutions
5. Traditional process vs. greener process
Products
Raw Materials,
Energy Chemical Pollution
Process Control
Traditional Process Wastes
Higher income,
Higher operating
Products costs
Modified Pollution
Raw Materials, Chemical Control
Energy Process
Wastes
Recycle Lower PC costs
GREENER PROCESS
6. Present engineering problems
Wireless radiation Hazardous air pollution
Heat radiation from Industrial solid waste
electronic devices
7. how it can be achieved..??
Using eco-friendly
Green technology. Reduce-Recycle-Reuse
8. Green future…
By 2020,european countries hopes to
reduce
Green house gas emissions by 20%.while
increasing reliance on renewable energy
sources by 20%
Photovoltaic system
With zero carbon emissions, this
technology will
Uncertainly help in overall reduction of CO2
Emissions.
Enhance geothermal systems
9. This solar array of panels trap an
unimaginably
source from several magnitudes and
converted
into electricity.
Orbiting solar arrays
Coal burning plants, utilizing this
technology
To separate carbon-dioxide during
electricity
Generation and buried in deep
underground
Without polluting atmosphere.
Carbon-capture storager
12. conclusion
In today’s environment, it’s matter of how long we live. because
our earth in
a critical position due to man made disasters. so, “GREEN
ENGINEERING”
should come into act to prevent & overcome environmental
problems.
*to overcome environmental pollution, the product should be
“REDUCE-REUSE-RECYCLE”.
