Green Initiatives – Sludge and Septage Management
byDr.S.S.Sivakumar & Jennifer Pandiyan
WASTE AS A RESOURCE
Resource use output + waste
Reuse of waste more output + lesser waste
Lesser waste zero waste
POTENTIAL OF SLUDGEClass I metropolitan cities (35) alone
• 40000 m3 per day of sludge are produced.
• 146 lac tones of biosolids fertilizer per annum which compares very favorably India’s total chemical fertilizer output per annum.
• Apart from its environmental benefits, if it can be sold just Rs2/kg the revenue would be Rs2920 crores/annum.
Initiative of our organisation
• Currently we are selling biosolids(US-EPA norms) to the farmers in Tamilnadu at Rs2/ to Rs5/ per kg.
• In addition, we are selling organic (FCO norms) soilless potting mix and growth nutrients for plants to urban customers as part of sustainable waste management process.
• Given full participation of all stake holders concerned, we should be able to sell 6 lac tones per year.

OUR PRODUCTS
POTENTIAL OF WASTE WATER Class I metropolitan cities (35) alone
20000 mld of treated water is available
2000 medium-large size irrigation tanks can be filled up each day with 11 months of irrigation
2.64million acres of land can be irrigated at 7000 ltrs/acre every day
Initiative of our organisation
• We started a comprehensive water management program among farmers in Chengelpet using only treated waste water for cultivation.
• In the pilot we’ve started with 2 types of crops.
• Treated water will be transported by trucks and stored in the farm.
SEPTAGE MANAGEMENT
• Outside of class I cities, most of class II and peri-urban areas are terrains of septage.
• In 2009, there were 100 million septic tanks all over the country at an average of 3000 ltrs septic tank.
• This translates itelf into 3 lac million ltrs of septage vastly higher than what class I cities produced.
SEPTAGE MANAGEMENT contd…
• There is no national plan for the use of this asset.
• We are preparing a plan for pilot 1 mld Common Septage Treatment Facility(CSTF), to be submitted to the government.
• Economically the earnings from CSTF will pay for its cost both CAPEX and OPEX.
• The organizational model will be that of Social Business, involving all the stakeholders.
