Bamboo : sustainable construction material Bamboo - fast growing woody grass 2’ per day India - 14 commercially useful species Second largest producer in world 75% Indian sub-continent – a natural habitat for

bamboo Grows from sea level to over 3500 metres

height 4 species - commercially used in Maharashtra Harvested in 3 to 5 years; yield of 6-8 tons

/year/acre No replantation required; self-renews with root

system Rural employment – numerous possibilities Important agent for climate change mitigation Tubular section – low weight; fibres bundled

together Periodic nodes – strengthening rings Good alternative to steel (steel has greater

embodied energy v/s bamboo) Light weight, flexible – good for prefab

construction

Waste from bamboo

Nothing is wasted Every part of bamboo is used

for different purposes; as a result, there is practically NO WASTE created.

Also, bamboo waste – when created, is BIODEGRADABLE

Waste shavings, pieces are used as fodder, converting it to MILK!
