Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Well, the easiest thing would be
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,to pour it down the drain;

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Many places have laws for proper disposal of grease,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,but we can go one step further.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Instead of just throwing it away safely,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,we can turn it into something useful.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And if you're wondering
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,what anyone could possibly want

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,which comes from long-dead dinosaurs
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and other ancient fossils.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,But diesel fuel can also be derived from

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,like plants and animals.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And this type of fuel is what we call biodiesel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Biodiesel is a biodegradable energy source,

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,that can usually be burned in regular diesel engines.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,You guessed it,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it's the 'bio' version of diesel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,It's cleaner than normal diesel,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so there has been a push to generate it
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,from crops like soybeans.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Now, growing crops for fuel
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,instead of food, comes with its own problems.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,But fortunately, we already have some oils and fats right here.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Preparing your used cooking grease for recycling
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is easy.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,First, let it cool down to room temperature.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Then, transfer it to a clean container.

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,like milk jugs,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,as long as they're completely empty
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,, rinsed, and dried.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Use a funnel to avoid spills
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and a civ to to filter out any small food particles.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,You can even add bacon grease,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and other animal fats,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,or the excess oil from canned food,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,like tuna or sardines,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,just make sure it's really oil and not brine.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, what happens now that your oil is safely contained?
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Many cities have recycling services,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,that will pick up large amounts of grease
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,from restaurants and other establishments.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,But there are locations

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,All of this grease will end up at a processing plant,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,where it can be converted to useable biodiesel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,How does this conversion work?
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,All these oils and fats you donated
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,are made up of triglycerides,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,a glycerol molecule connected to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,three fatty acid chains.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,To convert fats to fuel,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,they react with an alcohol,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,usually methanol or ethanol.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,, which produces long-chain esters and glycerol.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,To compare, here are some molecules
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,of regular diesel fuel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Now, here are some molecules we created
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,by breaking apart the triglycerides.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Glycerol is the odd man out,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so it's removed at the end of the process.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,But look at these esters!
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,If you squint, these structures look pretty similar
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,to those of the long-chain hydrocarbons of regular diesel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And diesel engines, with a few small modifications,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,can also be made to squint
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and burn these esters like regular diesel fuel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Et voila! Biodiesel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Now, you might be wondering
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,if all this hassle over recycled and used cooking oil
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is even worth it.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,After all, how much energy could it possibly generate?
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Well, if all the grease that New Yorkers throw away in one day,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,were converted to jet fuel,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it would be enough to power several hundred flights

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,And let's not forget that using waste oil
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,instead of burning more fossil fuels
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,will limit our negative effects on the environment.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Recycling used cooking grease
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,turns goop into good
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,By contributing a little bit,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,individuals and businesses can help create
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,an alternative, stable source of diesel oil,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,while protecting the environment
