Micro algal Carbon dioxide sequestration and biomass production in open raceway pond

Advantages / Salient Technical Features IPR Status / Details (India/Abroad)
• Eco-friendly, ambient temperature, low cost process. • Knowledge knowhow
Biological process for CO2 Sequestration. In outdoor
we were able to obtain algal biomass productivity of Application/Uses
about 15-17 g/m2/day at large scale raceway pond • Waste CO2 generating industries like Pow-
er plants, Steel industry, Cement plants,
Problem being addressed Bioethanol plants, Distillery, Boilers, etc.
• Cost effective eco-friendly technologies with some
profitability will enhance the efforts in mitigation Scale of Development
of CO2 emission through CCUS. Microalgal raceway • Pilot scale (Current TRL Level : 04)
pond cultivation enables capture and utilization of
CO2 to convert it into microalgae biomass rich in lipids Commercialization Status
(biofuel), fatty acids (PUFA/MUFA), carotenoids, • Not yet
antioxidants etc which may be extracted for bio-
refinery applications and value addition. Techno-economics
• NA
Environmental Considerations (if any)
• This is a process for dealing with CO2 emission Technology Package
in more natural way. CO2 is converted in natural • Process Demonstration
product like algal biomass which further has may
application including biofuel as renewable energy
source.
Major Raw Materials to be Utilized
• Waste CO2 gas, treated wastewater/ fresh water,
commercial fertilizers.
