About the Speaker
• Mr. Ashish V. Nawade- CEO• MBA- London Business School• 24 Years of international EPC experience in UAE, Japan, UK, Italy • Large project management, design and commissioning of 720,000 BOPD
oil processing, 600 MMSCFD gas processing, LNG plant, Sulfur Recovery Units and petrochemical projects.
• Worked on ADNOC, PDO, Shell, BP, BG, QP, Total, Chiyoda• Returned to India to work in Renewable Energy sector.
BioRenewablesEPC TURNKEY PROJECTS:
• BIOGAS TO POWER: Biogas genset based projects for conversion of waste to bio-power
• BIOGAS TO BIOCNG: Projects for conversion of waste to CNG grade fuel
Highlights of BioRenewable Projects
Feedstock• Agricultural Waste• Animal Waste• Industrial Waste (distillery/palm oil/starch/sugar/paper/food processing)• Sewage Treatment Plants (STP)• Municipal Solid Waste (MSW)
Beneficiaries• Farmers• Gas Producers• Gas Distribution Companies• Industries Producing Organic Effluents• Nations
Biogas to Power• Clean electricity from waste• More profitable option than firing biogas in boilers• 33 large-scale projects successfully commissioned by IETL across 16
different industries
Biogas to Power- Typical Plant Scheme
• Biogas Generation from organic solids/effluents.• Biogas Cleaning System for H2S removal (BIOSKRUBBERTM)• Biogas Fired Engine i.e. Biogas Genset.• Steam Generator running on Engine Exhaust.• Plate Heat Exchanger connected to Engine Jacket to recover jacket water heat.

• 140 MLD capacity STP at Rithala, New Delhi being constructed by M/S. Degremont India Ltd.; an Indian business unit of a French major in the STP space
• First biogas genset-based power generation plant in the Sewage Treatment sector in India
• STP Completely self sufficient in terms of electrical power requirements
• Operating successfully on BioskrubberTM since 2002. Operations and Maintenance Contract being carried out by us for the entire period since the commissioning
Biogas to BioCNG
• Highest return for every m3 of biogas
• Replacement of fossil fuel e.g diesel/petrol/CNG/LPG
• Pioneering projects - Inspiration for others
• Environmentally cleanest fuel- better than natural gas
• Renewable source of energy.

Biogas to BioCNG- Case Study
IETL has designed, constructed and commissioned the first large scale Biogas to BioCNG upgradation project for Spectrum Renewable Energy at Warana in India on pressmud and distillery biogas.
• IETL has provided the entire Biogas Upgradation Plant consisting of H2S cleaning and CO2 removal system
• Upgraded Biogas i.e. BioCNG contains more than 95% Methane, H2S less than 5 ppm and moisture at -40o C DP
• This BioCNG will be used as vehicular fuel/LPG replacement• The project status: Successfully commissioned

SulfabactTM- Biological SulfurNew formulation by IETL for development of activated biological sulfur as vital “S” nutrient additive under the brand name SulfaBactTM (Pat pending)
• Advantages of SulfaBactTM:• Timely availability of needed sulfur nutrient to plants • Activity of soil microorganisms enhanced on soil application due to optimum pH• No leaching out by rains, flooding as in sulfate fertilizers• Sulfur dispersion in soil very high and conversion very efficient due to colloidal
size of sulfur• Appropriate environment for microbes – slow release• All other pH dependant nutrients of soil slowly unlocked and made available to
plants.
