L3 Life Cycle Management 1
Life cycle thinking
20% of the world population are consuming
over 80% of the earth’s natural resources
Upstream and downstream
Extraction > Production > Distribution >
Consumption > Disposal
-life cycle thinking(LCT) – essential to
sustainable development
-going beyond the manufacturing/use
stages so as to include the environmental,
social, and economic impacts over its entire
life cycle
-main goals of LCT – to reduce a product’s
resource use and environmental impacts –
as well as improve socio economic
performance throughout the life cycle
-LCT means we know our choices
influence what happens at each stage
-LCT identifies both opportunities and risk
of a product/technology & helps to avoid
short term decisions
Eg- over fishing, polluting air with mercury
-LCT helps improve entire systems – not
only single parts of systems Eg switching to
coal power generation from nuclear power
-LCT helps avoid shifting problem
-LCT generates value and benefits for
business
Life Cycle Management (LCM)
-is a dynamic process, which collects,
structures and disseminate product related
to information from various programs,
concepts and tools with an aim to minimise
the environmental and social-economic
burdens associated throughout its entire life
cycle inorder to improve life cycle thinking
Product or service life cycle stages
1.Sourcing
2.Manufacture
3.Distribution
4.Use
5.Recovery
6.Transport
Combination of differelt life cycle
stages/phases of a product or service are
referred as
1. Cradle to grave -full life cycle from
raw material extraction to end life
disposal satge
Eg
clay>brick>house>use>demolition
>landfill
2. Cradle to gate – partial life cycle
from raw material extracton to the
factory gate (before it is transported
to consumer or for further
assembly)
Bauxite ore > alumina > aluminium
ingot
3. Cradle to cradle -full life cycle from
raw material extraction to use and
recycling and re-use at the end of
life stage (substantially recycled)
Clay > brick > house > use >
demolition > recycle & re-use
4. Gate to gate – partial life cycle ( i.e
only one value addition in the entire
life) eg assembly of car, powder
coating of auto part

Document Summary
20% of the world population are consuming over 80% of the earth"s natural resources. Life cycle thinking(lct) essential to sustainable development. Going beyond the manufacturing/use stages so as to include the environmental, social, and economic impacts over its entire life cycle. Main goals of lct to reduce a product"s resource use and environmental impacts as well as improve socio economic performance throughout the life cycle. Lct means we know our choices influence what happens at each stage. Lct identifies both opportunities and risk of a product/technology & helps to avoid short term decisions. Lct helps improve entire systems not only single parts of systems eg switching to coal power generation from nuclear power. Combination of differelt cycle stages/phases of a product or service are referred as life: cradle to grave -full life cycle from raw material extraction to end life disposal satge.
