Sciences
Systems-based, multidisciplinary discourse that seeks to understand
emergent behaviour of complex integrated human/natural systems.

4. Principles

Natural Systems reuse materials and have a largely closed loop cycling of
nutrients.
Using similar principles, industrial systems can be improved to reduce their
impact on the natural environment.

8. Case Study
Seshasayee Paper and Boards Ltd (SPB), in Tamil Nadu.
SPB started a paper mill, which went into commercial
production in 1962.
In order to ensure regular supply of raw material, a
sugar mill was set up. The waste from the sugar mill
(called bagasse) was used as a raw material for paper-
making.
Another waste from the sugar mill, molasses, was used
in a distillery nearby for the production of ethyl alcohol.
In order to ensure regular supply of sugarcane for the
sugar mill, the company took interest in the cultivation
of sugarcane by organizing the farmers in the region.

11. Definition and Goals
"Compilation and evaluation of the inputs, outputs and the potential
environmental impacts of a product system throughout its life cycle“
ISO 14040
Effects on environment of A decision making aid tool for
products and processes implementing sustainable
including packaging development

13. CASE STUDY

14. Products:
Shrink to Fabric, Medium
Stone wash type of jeans
Purpose:
To develop strategies to address the greatest impacts of business on the
environment
To addresses both environmental sustainability as well as sustainability of
the business

15. Life Cycle Inventory : ISO 14041

16. Life Cycle Assessment ISO 14042

17. Life Cycle Assessment ISO 14042

18. Life Cycle Assessment Interpretation ISO 14043
As per the results, the maximum environmental impact of the product is
at the use stage i.e. at the hands of the consumer.
Corrective measures: reduce the temperature of water and frequency of
washes

19. Life Cycle Assessment ISO 14043

21. Role of Levi
Partnership Care Labels
Technology

22. Life Cycle Impact Assessment
Evaluation of the significance of potential environmental
impacts based on the LCI flow results
Stages :
Classification
Characterisation

23. Life Cycle Assessment Interpretation
Systematic technique to identify, quantify, check, and
evaluate information
Results from the inventory analysis and impact
assessment are summarized during the
interpretation phase
Outcome of the interpretation phase is a set of
conclusions and recommendations for the study

26. LCA Benefit to Industrial Ecology
Only tool that examines the environmental impacts of a product or
service throughout its life cycle
ISO standardized method
Comprehensive overview of a product or service
Guides Company’s Decision Making

27. Conclusion
Industrial Ecology is the study of how we humans can continue
rearranging Earth, but in such a way as to protect our own health, the
health of natural ecosystems, and the health of future generations
ofplants and animals and humans. It encompasses
manufacturing, agriculture, energy production, and transportation
