Brooklyn high school becomes first in NYC to heat entirely with vegetable oil biofuel. Here's how it works.

"We can implement that in other buildings in the city [where] it makes sense, in your local hospital, your libraries, even your apartment complexes,"

"If we implement that across all of those buildings, we could really save a lot of carbon emissions."

"And that oil is repurposed into our boilers with a catalyst and a couple of additives. And we actually make it into diesel fuel,"

"If you ever leave here around 3 p.m., you'll see that it's one of the most congested neighborhoods in the city. There's a lot of legacy fuel being utilized to power cars, trucks all around this neighborhood,"

Edward R. Murrow High School in Brooklyn now heats its entire campus with vegetable oil biofuel rather than traditional fossil fuels. Four boilers in the school's basement power roughly 4,000 students and run on repurposed cooking oil processed with a catalyst and additives into diesel. The installation represents the first full-campus renewable heating conversion at a New York City school and has passed its first cold-weather test with no noticeable loss of indoor heat. The system offers potential scaling to hospitals, libraries, and apartment complexes and could reduce local carbon emissions in a congested, polluted neighborhood.
