John Ellersick, President

John Ellersick is an entrepreneur, Chemical Engineer, and organizational leader with over 25 years of experience developing technologies in the energy, renewables, water treatment and environmental sectors.

As Oasys Water’s Vice President of Projects, he has been responsible for the delivery of Forward Osmosis based projects which treat some of the world’s most abused industrial waters from sources such as power plant flue gas desulfurization, oil and gas production, industrial utilities blowdown and coal to chemicals waste sources. These projects are working towards achieving waste minimization, water recovery and reuse, and the adoption of true Zero Liquid Discharge (ZLD) at industrial facilities worldwide.

Prior to Oasys, John led major scale-up and commercialization programs in the renewables sector including bio-industrial chemicals (primarily succinic acid) with Myriant Corporation, cellulosic ethanol with Mascoma Corporation, and cellulose to fuels/chemicals (levulinic acid) with BioMetics and LeCalorie.

The professional building blocks for these development efforts came from John’s experience addressing many of our country’s most difficult environmental challenges working with AECOM (ENSR), and conducted energy technology design and development with Raytheon Engineers & Conductors (Badger).

John holds a Master’s Degree in Engineering Management from the Tufts Gordon Institute, and a Bachelor’s Degree in Chemical Engineering from Northeastern University.  John is a licensed MA professional engineer #41815, and a Project Management Professional (PMP) as certified by the Project Management Institute.
