KEY PROJECTS/ EXTERNAL REPRESENTATION

Conceptualized, developed, and designed (process design) the first-of-its-kind (patent-applied) algae-based wastewater treatment solution to mitigate all aqueous effluent streams at the site. Saved millions of pounds in CAPEX-OPEX and carbon emissions for the manufacturing site.

Conceptualized & designed (2012-13), commissioned (2016), demonstrated (2017), and operated (2017-Aug’2018) the world’s first integrated, end-to-end, large demonstration plant for biocrude production using marine microalgae produced from CO2.

Successfully secured funding as a co-Principal Investigator from RIL in the United States Department of Energy (US DOE) sponsored PACE (Producing Algae for Chemicals & Energy) project in 2015.

Participated as a co-Principal Investigator from RIL in the US DOE-sponsored NAABB (National Alliance for Algae Biofuels & Bio-products) from 2011-2014.

In 2009, PRAJ contributed heavily towards the preparations of the Indian Prime Minister’s Convoy to Copenhagen Summit. Was a vital member of the team that conducted, compiled & presented life cycle analysis studies on a few renewable energy options, to the PM’s Convoy.

In 2005, conceptualized, networked, compiled, and successfully bid for a proposal for a Joint Indo-US Centre of Excellence for Bioremediation at Agharkar Research Institute (ARI). This project was funded by the Indo-US Science & Technology Forum (IUSSTF).
