What are we doing<br />
What are we doing different
An Integrated Approach to Innovation- Social,<br />
Financial and Environmental<br />
16% of India GDP is from Agriculture<br />
10 million farmers (50 million people)<br />
connected to sugarcane farming
Godavari Biorefineries Context<br />
2011-12, we processed 2.1 million tons of cane<br />
15,000 farmers - an average of 140 tons<br />
cane/farmer (33% of our farmers supplied less<br />
than 50 tons)<br />
Average landholding 3.5 acres (40 tons/acre)<br />
Cane price = $50/ton: So about Revenue<br />
about $7000 per ‘average’ farmer
Single crop vs Intercropping:<br />

Soya Quintals 8 $ 75 $ 600 $ 20<br />
Turmeric Quintals 15 $ 160 $ 2400 $ 80<br />
Total for 1<br />

Total for 3.5<br />

Single crop 1 acre 40 $ 50 $ 2000<br />
3.5 acres $ 7000<br />
Dramatic Changes in revenue, with better effect on soil quality !!

Earlier, when we started, sugar yield per ton was 93 kg, now it is 115 kg. Before the WTO outlawed<br />
subsidized EU sugar exports, sugar prices were $0.2/kg, leading to a revenue from 1 ton cane of about<br />
$20, compared to $66 above

Godavari Strategy<br />
Add Value<br />
Diversify across markets<br />
Diversify across renewable feedstock (Beet, Cane, Sorghum,<br />
Glycerine)<br />
Diversify manufacturing locations<br />
Invest in startups<br />
Innovate in feedstocks, processes, and relationships<br />
Work with farmers<br />
Work with and for the community
