4. Explanation
Sustainable product design is the philosophy of designing physical objects,
to comply with the principles of economic, social, and ecological
sustainability.
Economic sustainability
is not just about achieving
economic growth year on
year. It’s about
understanding that economic
growth is only sustainable if it
simultaneously improves our
quality of life and the
environment
Social sustainability
encompasses human rights,
labor rights, and corporate
governance
Ecological Sustainability
Capacity of ecosystems to maintain
their essential functions and
processes, and retain their
biodiversity in full measure over the
long-term

5. Sustainable design
 Sustainable design is a kind of design
meant to yield products that are made
only of renewable resources.
Furthermore, products made though
sustainable design are intended not to
seriously impact the environment either
when they are being created or when
they are being used. These products are
also often designed to allow the users to
feel more connected or to relate more
closely to the natural environment.

6. Sustainable design
 Sustainable design is also called
"environmental design" and
"environmentally-conscious design." It is
also sometimes called "environmentally
sustainable design" or "ESD." No matter
what it is called, this kind of a design is
just as much a philosophy as it is a
practice. It is based on economic,
ecological, and social principles
regarding the importance of
sustainability.

7. How to make sustainable
design?
1. Ma k e i t l e s s c o m p l e x
◦ Simple, elegant designs can reduce material,
weight, and manufacturing processes. Simple
designs usually also mean less material
variety and can help make a product more
recyclable.
2. M a k e i t m o r e u s e f u l
◦ there is a big difference between usefulness
and complexity.Only make the product more
desirable and interesting, it will also help
reduce the number of products headed for
landfills. Multiuse products can reduce
consumption and increase convenience.

8. 3. r e d u c e m a t e r i a l v a r i e t y
◦ Designing as many aspects of the product as
you can from the same material makes
recycling the product at its end of life easier,
more efficient, and more profitable.
4. A v o i d t o x i c o r h a r m f u l m a t e r i a
l s a n d c h e m i c a l s
◦ Materials like PVC, neoprene or polystyrene,
and toxic chemicals and additives like bisphenol
A and formaldehyde should be avoided when
possible. Many of these materials have suitable
non-toxic counterparts, like copolyesters or
bioplastics, and additives can be eliminated by
choosing materials wisely.
5. r e d u c e s i z e a n d w e i g h t .
◦ Lightweight products can reduce carbon
emissions and cost Weight can often be saved
by focusing on choosing lightweight materials,
simplifying designs, and eliminating
unnecessary fasteners and components.

9. 6. D e s i g n f o r u p g r a d e a b i l i t y .
◦ In the electronics industry, the technology
in a product can become obsolete long
before the design.
◦ Designing products that can be upgraded
to keep up with rapidly changing technical
performance can save materials and
money.
7. C r e a t e d u r a b l e a n d h i g h q u a l i t
y d e s i g n s .
◦ People want high quality products that will
look and function beautifully long after the
competing product has died, and they’re
willing to pay a little more for that type of
design.
◦ Designed properly, products can exceed
the “throw away” culture that dominates
electronics today.

10. 8. D e s i g n f o r l i f e a f t e r d e a t
h
◦ Most products don’t last forever. Products
designed to have secondary usages after
their primary function has lapsed can add
value to the product, and may fill a need
that would be filled by another purchased
product instead.

11. PRINCIPLES OF SUSTAINABLE PRODUCT
DESIGN
 Efficient use of raw materials (e.g. lightweight construction with
regenerative materials and reduction of waste)
 Resource efficient design (e.g. by optimization of energy and
water consumption or using less virgin materials)
 Durable design (e.g. stable construction and high longevity)
 High disposability (e.g. use of easily degradable materials)
 Efficient logistics (e.g. minimized packing and efficient transports)
 Service substitution (e.g. car-sharing and similar per capital
resource consumption reduction strategies achieved through
redesigning ownership structures)
 Proper training and education for the workers (e.g. at the
production site)
 Observing and complying with human rights issues (e.g.
discrimination based on gender or race at production sites)
 Worker‘s health and safety (e.g. proper gear and equipment in
toxic environments)
 Consumer health & safety (e.g. informing the consumer via

12. Categorization of Sustainable
Products
1. Biological Products
2. Technical Products

13. 1) Biological Products
 A biological product is one which is
made of biological nutrients like
organic material such as wood and
can easily be consumed by the
microorganisms in the soil or by other
animals. So that it continues in the
cycle of nature.

14. 2) Technical Products
 A technical product is one that is made with
technological nutrients like industrial
materials such as metals or plastics and
designed to go back into the technical cycle,
or the cycle of industry. It can continually
enrich the industry by being consumed as
industrial “food.”
 During recycling, if the metals would be
smelted only with like metals then they will
retain their high quality; likewise for plastics
and thus continue to circulate in the cycle of
industry as technical nutrients.

15. Current Trend of Product
Design
 Unfortunately, most of our today’s products
are a hybrid of biological and technological
nutrients, and they end up as waste for the
reason that they are not properly designed to
continue for high quality or we can say “up-
cycle” reuse after their useful lives.
 With the right design, all of the products and
materials manufactured by industry will safely
feed these two metabolisms, providing
nourishment for something new.

16. Examples of sustainable design

18. SOLAR
ENERGY

19. Solar energy
 Solar energy is an alternative energy source
that involves harnessing the radiant light
energy emitted by the sun and converting it
into electrical current. Since the middle of the
20th century, the ability to harness and utilize
solar energy has greatly increased, making it
possible for homes and businesses to make
use of the renewal energy source rather than
rely on more conventional means of
generating power. Research into the
applications of solar energy continue, along
with the development of more cost-effective
ways to capture and store the energy for
future use

20. Some facts!
 About 30% of total energy received by the earth is
reflected back towards the space Remaining
energy is absorbed by the clouds oceans and land
masses
 The amount of solar energy reaching the surface of
the planet is so vast that in one year it is about
twice as much as will ever be obtained from all of
the Earth's non renewable resources of coal oil
natural gas and mined uranium combined
 Solar energy is the primary energy source among
all of the renewable source like wave energy hydro
electricity

21. Explanation
 The Earth receives
174 petawatts (PW) of
incoming solar radiation
(insolation) at the upper
atmosphere.[1] Approximately
30% is reflected back to space
while the rest is absorbed by
clouds, oceans and land
masses. The spectrum of
solar light at the Earth's
surface is mostly spread
across the visible and near-
infrared ranges with a small
part in the near-ultraviolet.

22. Applications
 Solar energy refers primarily to the use of solar
radiation for practical ends. However, all
renewable energies, other than geothermal and
tidal, derive their energy from the sun.
 Solar technologies are broadly characterized as
either passive or active depending on the way
they capture, convert and distribute sunlight.
 Active solar techniques use photovoltaic
panels, pumps, and fans to convert sunlight into
useful outputs.
 Passive solar techniques include selecting
materials with favorable thermal properties,
designing spaces that naturally circulate air, and
referencing the position of a building to the Sun

23. Solar water heater
 Solar water heater uses solar
collector panel to transfer the
heat energy of sun light to the
water
 The unit uses convection
movement of hot water upward to
move the water from collector to
tank .Neither pumps nor
electricity are used to enforce
circulation
 Material uses into the fabrication
of tank is insulator for heat so
heat of the hot water can not
transfer to the surrounding
environment and hence water
can be keep hot

24. solar cells
 Principle: Some materials release
electrons when hit with rays of light
which produces an electrical current
 This effect was discovered by
Alexander Edmond Becquerel The
first solar cell was constructed by
Charles Fritts in the 1880.

25. What is a Solar cell?
 A structure that converts solar energy
directly to DC electric energy.
 It is like a battery because it supplies DC
power.

26. Uses of solar cells
 Solar cells are very
useful in powering
space vehicles such as
satellites and telescopes
(e.g. Hubble). They
provide a very
economical and reliable
way of powering objects
which would otherwise
need expensive and
cumbersome fuel
sources.

27. Uses of solar cells
 Solar powered cars
are cars which are
powered by an
array of
photovoltaic cells.
The electricity
created by the solar
cells either directly
powers the vehicle
through a motor, or
goes into a storage
battery.

28. Solar panels
 A solar panel
(photovoltaic module or
photovoltaic panel) is a
packaged interconnected
assembly of solar cells,
also known as
photovoltaic cells. The
solar panel is used as a
component in a larger
photovoltaic system to
offer electricity for
commercial and
residential applications.

29. Solar panels
 Because a single solar panel can only
produce a limited amount of power,
many installations contain several
panels. This is known as a
photovoltaic array. A photovoltaic
installation typically includes an array
of solar panels, an inverter, batteries
and interconnection wiring.

30. Advantages of solar panels
 Many of us worry about our fuel bills and the
environmental impact of our fuel
consumption, while a free and clean source
of energy is shining down on us all day. In
one minute, the sun gives the earth enough
energy to meet the earth's power needs for a
year. If you install a solar panel in your
house, you are tapping into this massive
source of free energy, and slashing your fuel
bills. There are also great environmental
benefits to solar energy, as it produces no
pollution.

31. Advantages of solar energy
 Solar Energy Is Abundant
 Solar energy is everywhere, it’s abundant and we’ll
practically never run out. Even in mid winter we are
blessed with a moderate amount of natural daylight
provided courtesy of the sun. Okay, it might not be
sunny everyday but we are still experiencing radiation
from the sun and it is this which can be gleaned for our
own renewable energy purposes. Thus the need for
finding a long lasting energy resource is over!
 Solar Energy Is Free
 Solar energy is completely free. Sure, there is an initial
capital cost but once you have made the investment the
energy harvested from the sun costs you nothing. No
one will be sending you a bill for sunshine. Thus no
worries of spending enormous amounts of your salary
in satisfying your energy requirements.

32. Advantages of solar energy
 Solar Energy Is Cost Effective
 While solar photovoltaic are still relatively expensive,, the technology
is growing rapidly as is production – and as a result the costs
involved are coming down and is now cost effective. Solar hot water
panels have been greatly improved in recent years and, with lower
cost, payback times for domestic systems can no be as short as five
years. As coal, gas and oil prices continue to rise solar energy will
become a viable alternative. It’s secure. We live in uncertain times
and we are increasingly relying on our fossil fuel supplies coming
from areas abroad over which we have little or no control.
 Solar Energy Is Clean
 Finally solar energy is clean. It is a clean alternative to fossil fuels
and nuclear power and it will never run out. It’s silent. Solar power
can be captured anywhere without creating noise pollution that might
otherwise up set neighbours and wildlife. It works wherever the sun
shines. It doesn’t matter how remote, solar can generate energy
where no other form of power can be obtained. Thus, no danger of
damaging our already damaged environment further and you can be
part of the Green initiative, lower your carbon footprint, and save our
planet from harmful greenhouse gases.

33. Final Thought
 Sun provides power only during the day is
countered by the fact that 70% of energy
demand is during daytime hours. At
night, traditional methods can be used to
generate the electricity.
 Goal is to decrease our dependence on
fossil fuels.
 Currently, 75% of our electrical power is
generated by coal-burning and nuclear
power plants.
 Mitigates the effects of acid rain, carbon
dioxide, and other impacts of burning coal
and counters risks associated with
nuclear energy.
 pollution free, indefinitely sustainable.
