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 Sulfur
New 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.
