this oil helped make a delicious meal possible.

Many places have laws for proper disposal of grease,

with a bunch of disgusting, used cooking oil,

They power farming and construction equipment,

trucks, buses, ships, trains, backup generators,

Most of the fuel that feeds these engines

And this type of fuel is what we call biodiesel.

Biodiesel is a biodegradable energy source,

that can usually be burned in regular diesel engines.

instead of food, comes with its own problems.

But fortunately, we already have some oils and fats right here.

Preparing your used cooking grease for recycling

First, let it cool down to room temperature.

You can use any old bottles you have lying around,

and a sieve to filter out any small food particles.

Well, many cities have recycling services

that will pick up large amounts of grease

from restaurants and other establishments.

where individuals can drop off their containers, as well.

All of this grease will end up at a processing plant,

where it can be converted to useable biodiesel.

Well, all these oils and fats you donated

which produces long-chain esters and glycerol.

so it's removed at the end of the process.

If you squint, their structures look pretty similar

to those of the long-chain hydrocarbons in regular diesel.

And diesel engines, with a few small modifications,

and burn these esters like regular diesel fuel.

Now, you might be wondering whether all this hassle

After all, how much energy can it possibly generate?

Well, if all the grease that New Yorkers throw away in one day

it would be enough to power several hundred flights

And let's not forget that using waste oil
