Newport-Biodiesel-KF-Titrator-1200x627From supplying a fryolator to heating homes and sustaining transportation - cooking oil becomes fuel.

Newport Biodiesel, located in Newport, RI, produces 8 million gallons of biodiesel annually. The company takes and processes waste cooking oils from over 5,000 businesses from New Hampshire, Massachusetts, Rhode Island, and Connecticut. 

Biofuel That's Held To A High Standard


Various restaurants and facilities around the US produce billions of gallons of waste oil a year, and all of that used oil has to go somewhere. Instead of it heading to a waste facility, why not recycle it to benefit us? Cooking oil that would usually just be "trashed" can undergo a cleaning and refinement process to be used to heat buildings and fuel transportation.

Newport Biodiesel and its hardworking team process and produce biofuel in accordance with ASTM D6751. Used cooking oils are clarified by removing any solids and water, and then they are put through a chemical process that produces biodiesel and glycerin. 

Newport Biodiesel & Hanna Instruments


The partnership between Hanna Instruments and Newport Biodiesel began in 2017 when John Fitzgerald (Production Manager) discovered Hanna and the instrumentation that we offer. Needing a new coulometric Karl Fischer titrator, John did his research and chose Hanna's Coulometric Karl Fischer Titrator (HI904) to replace his aging unit. Newport Biodiesel used coulometric titration to monitor incoming waste oil moisture as well as the outgoing biodiesel moisture. Like with any fuel, you want to have as little moisture as possible in the finished product. Having a coulometric titrator onsite means the biodiesel-making process can be monitored practically in live time. Tweaks can be made before there is a big issue.

"If you're cost-conscious and want to avoid downtime, it's the equipment to have."

- John Fitzgerald, Production Manager
