Technology vs

environmental impact

kProvides benefit for better quality of human life

� Gives environmental impact



evidence

y Easter island

y stack in China (80% of worlds stack)y Born babies suffering from bad disease, mental

retardation (caused by polluted environment,mercury, etc.)

y Global warming and climate change



What causes the problems

I = P * A * T

I Environmental Impact

P Population

A A ffluence (Consumption of serviceand product per capita)

T Technology (environmental burdenper product or service unit)

The Ehrlich-Holdren Equation by Paul Ehrlich and John Holdren (1970s)



The Future?

Global development

y North 2% growthy South 6.7% growth

y Asia = 60% of world·spopulation

y 22% of region·s popabsolute poverty



Engineers are core players

y but can engineers (on their own) do the

job?

y Social and technological issues are increasinglyinterconnected

y Strategic thinking in technology

y Stakeholders involvement



What is new?

y We face the limit of our planet: there is

no place to go if we mess it upy We need leap of technology, not just

optimization

y We live more and more in participatory

society, and so we need stakeholdersinvolvement



Environmental efficiency?y Environmental impact

/(passenger*km)



Control dilemma

y A new technology can be adjusted in itsearly stages

y But we hardly know its effect

y Only later we see the effect

y At that time, adjustments are almostimpossible

Negative effect is known innovationof technology



Rebound effect

Technology cheap energy more consumption per capita ??



What can technology contribute to

solve environmental problems?

y 3-D technology:

y

Dumping (waste in pits, etc)y Displacement (moving pollution by sewerage)

y Dilution (fluid waste)

yEnd of pipe tech (incineration, pyrolysis,

fermentation, chemical treatment)y Sustainable technology, sustainable resource

management, circular economy



Sustainable technologies

yare those technologies that fulfil the

needs of mankind without the use of

non-renewable resources, and without

creating large scale, and/or irreversible

damage

ydoing more with less



Sustainable development

y is a pattern of resource use that aims to meet humanneeds while preserving the environment so that theseneeds can be met not only in the present, but also for

generations to come. The term was used by theBrundtland Commission which coined what hasbecome the most often-quoted definition of sustainable development as development that "meets

the needs of the present without compromising theability of future generations to meet their own needs."
