•The term “Industrial Ecology” was
first introduced by Harry Zvi Evan
at a seminar of the Economic
Commission of Europe in 1973.
Where did the idea “Industrial Ecology”,
• "why would not our industrial system behave
like an ecosystem, where the wastes of a
species may be resource to another species?
• Why would not the outputs of an industry be
the inputs of another, thus reducing use of
raw materials, pollution, and saving on waste
Approach to managing human activity on a
sustainable basis by.
• essential integration of human systems
into natural systems.
• Minimizing energy and materials usage.
• Minimizing the ecological impact of human
activity to levels natural systems can
Some of the systemic problems
•Dealing with regulated waste is a direct
cost to the business.
• Un-regulated waste is an indirect cost to
your employees, your customers, and you.
• At best, waste is an inefficiency, a
• On a planet, resources are finite if not
replenished via cycles.
•Does not externalize costs to society, your
employees, you or your family
• Increased efficiency
•Increases innovation in yours and other’s
• May give rise to new product lines or services
• Reduces costs
• Increases revenues
Industrial Ecology in Practice
Input - Output analysis at the systems level
By-product exchange and energy cascading
Physical connections between production units
– close proximity of industry on one site
Systems approach outside an Industrial estate
No management and formal research involved
•Is when you put things like
glass,plastic,paper/cardboard into different
coloured bins to be turned into something new
example. Cardboard can be turned into a new
•Recycling saves land, reduces the amount of
solid waste, energy consumption and pollution.
•Recycling does have environmental
•It uses energy and generates pollution.
•Ex. the de-inking process in paper
recycling requires energy, and produces a
toxic sludge that contains heavy metals.
•Conserves our natural resources
•Has a positive effect on the economy by
generating jobs and revenues.
•For example, the Sunday edition of the
New York Times consumes 62,000 trees.
•Currently, only about 20% of all paper in
North America is recycled
•Each family living in the UK uses 500
glass bottles and jars on average every
• Glass is 100% recyclable and can be used
again and again
• The largest glass furnace produces over
1million glass bottles and jars every day
• Glass that is thrown away ends up in
landfills and will never decompose (it will
never rot away )
Paper and Cardboard
•Recycled paper produces 73% less air
pollution than other materials
• 12.5 million tonnes of paper and
cardboard are used annually in the UK
• the average person in the UK goes
through 38kg of newspapers every year
• It takes 24 trees to make 1 ton of
•2,75,000 tonnes of plastic is used each year
in the UK that’s about 15 million bottles a
• Most families throw away 40kg of plastic
a year which could be recycled
• plastic that ends up in landfills can take
up to 500 years to decompose (rot)
•The use of plastic in western Europe is
going up by 4% every year
Many people underestimate Recycling
•Tons of everyday items can be recycled,
things like plastic, glass, aluminium and
paper/cardboard are all things that we just
throw away instead of recycling them.
• Many people underestimate the benefits of
recycling and how it would be better for the
• So before you throw away your rubbish
that can be recycled just think
polluting a river
man in the boat is
looking for items
to salvage or sell
