LCA benefit for
Systems-based, multidisciplinary discourse that seeks to understand
emergent behaviour of complex integrated human/natural systems.
Natural Systems reuse materials and have a largely closed loop cycling of
Using similar principles, industrial systems can be improved to reduce their
impact on the natural environment.

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-
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.
The company strike long-term agreements with the
farmers to buy back their produce and, in turn, took the
responsibility of supplying them with water.
Much of the water supplied for cultivation was the
treated wastewater from the paper manufacturing
The company also used bagasse pith (a waste after the
paper making) and other burnable agricultural wastes
in the region, as an energy source in their captive

Guides Company’s Decision Making
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
