4. The current world view
- relative importance?
Economy laws are
‘inevitable’ - market
laws
Environment
Environment is used to fulfill
(‘technology
the demands of the Economy
can fix it’) laws. (Resources, waste and
pollution absorption)
Economy
(‘inevitable laws’)
Society adapts to the
inevitable economy laws:
As much money as sooner as
Society possible.

SO: why do so many regard Economic laws as ‘inevitable’ (globalisation, etc); but
Environmental laws, and limits, as manipulable?

7. Serving Needs, or Quality of Life, or
Wants?
• “Traditional cultures, having more limited means
to satisfy human needs, tend to meet as many
needs as possible with as few resources as
possible.
• In contrast, industrial capitalism emphasises the
creation of specialised products that fight for
market niches to fill ‘needs’ that, as often as not,
cannot be satisfied by material goods.
(Natural Capitalism, Ch. 14)

8. Example: which of these is more worth
an engineer’s energy & interest?
Hasbro's Tooth Tunes toothbrushes have an MP3 player
built in. They use bone-conduction to rattle the sound through
your teeth for 3 minutes, making sure you brush for the
American Dental Association's recommended time.

9. Example: which of these is more worth
an engineer’s energy & interest?
Design of Temporary Shelters for Refugees
Thousands of refugee deaths from
hypothermia could be prevented every
year if a new hi-tech UK-designed tent
lining performs well in tests in
Afghanistan. A team from the University
of Cambridge has developed linings for
existing refugee tents that will pay for
themselves in saved heating costs in one
winter.
They are made of a sandwich of
materials: polyester wadding like you'd
find in a puffa jacket and a cheap
breathable waterproof membrane.

12. What defines a socially
sustainable product?
• Is being manufactured sustainably enough,
whatever the product’s social impact?
• Or, should engineers push for socially
sustainable features in the products: for
instance….affordability and accessibility for
the ‘excluded’ - the poorest 10%?
• Or, should we put our energy and interest into
products and projects which serve ‘needs’
rather than artificially created ‘wants’?

14. Enterprise core
Course SUSTAINABLE DEVELOPMENT
NTUU “KPI”, 12-23 February 2007
15. Enterprise relation to Society
The company is part of a supply chain, with suppliers and customers and a market, our
share of which we hope to increase. Products flow through that supply chain in one
direction; money flows in the other direction.

17. 1. Zero Waste
Against ideal operational
standards—zero waste—
they identified $70 million
in waste, based on 1994
operations—10 percent of
sales!
Course SUSTAINABLE DEVELOPMENT
NTUU “KPI”, 12-23 February 2007
18. 1. Zero Waste
Total manufacturing waste sent
to landfills has decreased by
63% since 1996.
The cumulative avoided costs
from waste elimination activities
since 1995 have totaled over
$299 million.
Course SUSTAINABLE DEVELOPMENT
NTUU “KPI”, 12-23 February 2007
19. 2. Benign Emissions
Interface identified and inventoried 247
air emissions stacks and 19 waste
water effluent pipes at their
manufacturing locations.
Course SUSTAINABLE DEVELOPMENT
NTUU “KPI”, 12-23 February 2007
20. 2. Benign Emissions
Reduced the number of stacks on its
facilities by 35 percent and the number
of effluent pipes by 53 percent.

21. 3. Renewable Energies
The third front, Renewable Energy,
means eventually harnessing solar
energy
Harnessing renewable energy will
attack numerous unwanted
linkages, both to the lithosphere
and to the biosphere, and will allow
closed loop recycling
Course SUSTAINABLE DEVELOPMENT
NTUU “KPI”, 12-23 February 2007
22. 3. Renewable Energies
An emphasis on initiatives that
improve efficiency and conserve
energy has reduced the total energy
used at carpet manufacturing facilities
(per unit of product). It is down 41%
since 1996.
use of
renewable
energy
increased
from 11%
to 13% in
2005.

NTUU “KPI”, 12-23 February 2007
23. 4. Closing cycles
Two cycles are introduced:
a natural, organic cycle,
emphasizing natural raw
materials and compostable
products (quot;dust to dustquot;)
a technical cycle, giving man-
made materials and precious
organic molecules life after life,
through closed loop recycling.
Course SUSTAINABLE DEVELOPMENT
NTUU “KPI”, 12-23 February 2007
24. 4. Closing cycles
The ReEntry program diverted 85
million pounds of material from
landfill between 1995 and 2005.
In 2005, 18 million pounds was
diverted from landfill and used in
recycling (71%), energy capture
and conversion (28%), and
repurposed (1%).
The percentage of recycled or
biobased content in products
worldwide has increased from
0.5% in 1996 to 15.9% in 2005.

NTUU “KPI”, 12-23 February 2007
25. 4. Closing cycles
Water intake per square meter
of carpet is down 81% in
modular carpet facilities and
down 52% in broadloom facilities
from 1996 due to conservation
efforts and process changes

26. 5. Efficient resources/goods transport
We can:
• videoconference to avoid the
unnecessary trip for a meeting.
• drive the most efficient
automobiles available.
• site our factories near the markets
they serve
• plan logistics for maximum
efficiency
Course SUSTAINABLE DEVELOPMENT
NTUU “KPI”, 12-23 February 2007
27. 6. Sensitivity Hookup
• service to the community through
involvement and investment in the
community (especially in
education),
• closer relations among ourselves
(inside the circle) to get all of us in
alignment, and with suppliers and
customers.

29. 7. Redesign of commerce
Redesigning commerce probably
hinges, more than anything else, on
the acceptance of entirely new notions
of economics, especially prices that
reflect full costs.
It means shifting emphasis from
simply selling products to
providing services
Relationships based on delivering, via
leasing agreements, the services our
products provide, in lieu of the
products themselves
Course SUSTAINABLE DEVELOPMENT
NTUU “KPI”, 12-23 February 2007
30. 7. Redesign of commerce
Other examples:
Photocopies: Xerox: Sells copy services instead of copy
machines.
Elevator: Schindler, Sells vertical transport maintenance free
instead of elevators
We can go farther:
In ICT: You can buy hours of word editor instead of hardware
and software.
In civil engineering: you can provide the service: connection
between two places instead of roads. The enterprise is
responsible for maintenance, in case of interruption enterprise
is fined.

31. • service oriented
• resource-efficient
• wasting nothing
• solar driven
• cyclical (no longer take-make-
waste linear)
• strongly connected to
stakeholders: communities
(building social equity),
customers, and suppliers—
and to one another.
• Our communities are stronger
and better educated
