>> A Thanksgiving by product that would normally end up down the drain or in a landfill is getting a second life.

Thanks to an annual event held by the University of Kentucky for more than a decade.

People have brought their used cooking oil to a collection site during the gobble grease toss.

The oil is then turned over to UK researchers who turn it into bio-fuel feel.

We spoke to one of the researchers about the process.

>> Boyle's have been converted into fuels for decades now.

Obviously the first cases is patrolling of oil.

We mainly work converting fats, oils and greases into sustainable renewable fuels.

And so we do this.

We catalyst, which are materials that accelerate chemical reactions.

We take these fats oils and greases or fall for short and we with the use of these got a list, convert them into renewable diesel or sustainable aviation fuel.

For over 10 years.

Now, we have been trying to improve an existing technology, 2 dedicated to specifically for the East peace talks.

We rather work with some will want something that is more away street.

So something that is going to be say disposed off landfill in a landfill.

These materials would generate methane, which is an even more powerful greenhouse gas than Co 2.

So we can diverted away from the landfill and produce a renewable fuel out.

If folks were 2 for these.

Used cooking oil down the drain.

It will hurt the plumbing at home and also at the city sewer system.

If you Google something like that, birds just like I spear, but with fats instead of ice, you will buying these monsters in the sewer system that can clog the entire sewer and cause the long haul problems that are expensive to fix and that's taxpayer dollars.

So the very best thing that they can do, it's something that this collection says that would completely avoid all of those problems for 15 years.

Now that we've been doing this, we probably can't.

Several 1000 gallons of this waste stream out of the sewer system and away from the left.

>> UK researchers estimate almost 500 gallons of used cooking oil has been collected in the last 15 years since the
