Current Waste Treatment TechnologiesDisadvantages

- High in CAPEX- High in OPEX- No or Low Return on Investment- Not attractive for private participation- Suitable for developed countries

Need for Waste Valorization Technologies- That generate value from waste and create jobs- That attract private enterprises

The Next Opportunity: MLW and MSW

Known Attemptswith partial successes

80% water goes untreated with great cost to nation

Municipal Sewage Treatment Plant- High on OPEX Rs. 15 lakh/day for 100 MLD; 40KW/MLD- High on CAPEX Rs. 100 crore for 100 MLD STP- Generates sludge for disposal Not clean technology

Novel Concepts of MLW to grow MicroAlgae

Sewage water + Sunlight + CO2 Algal biomass + Clean Water & Air(MLW)

Bio-CNG

Traditional Sewage treatment for Clean water from MLW

100 MLD Sewage Rs. 15 lakh/day O&M cost+ Rs. 100 crore plant cost

Consumes Energy 40KW/MLD

MLWMicroalgae Bio-CNG and Clean Water and Clean Air

100 MLD sewage 40 ton dry algae 10 ton Bio-CNG Rs. 5 lakh/day @ Rs. 50/kg CNG (methane) Plant cost ~ Rs. 200 crore

Generated energy equivalent 20 KW/MLD
