程度副詞

this oil helped make a delicious meal possible.

但現在，它只是一坨噁心的糊糊

和其他隨機的東西集結在一塊兒

Many places have laws for proper disposal of grease,

很多地方設有妥善處置油脂的法規

不僅僅只是 把它仍到其他安全的地方

我們其實可以把它變成有用的東西

with a bunch of disgusting, used cooking oil,

可以變成什麼 人們想要的東西的話

They power farming and construction equipment,

trucks, buses, ships, trains, backup generators,

卡車、 公車、 船舶、 火車、 備用發電機

Most of the fuel that feeds these engines

And this type of fuel is what we call biodiesel.

這種類型的燃料 就是我們所說的生物柴油

Biodiesel is a biodegradable energy source,

that can usually be burned in regular diesel engines.

通常可以在常規的 柴油引擎中燃燒

所以人們試圖 推動這種能源的使用

instead of food, comes with its own problems.

卻作為燃料之用，已造成許多問題

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

但幸運的是，我們在這裡 已經有一些油和油脂了

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.

並用篩子過濾掉 任何小的食物顆粒

just make sure it's really oil and not brine.

So, what happens now that your oil is safely contained?

現在你的油已經安放在容器裡了 那麼，接下來該怎麼辦？

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,

所有這些油脂最終會來到加工廠

where it can be converted to useable biodiesel.

在那裡，它可以轉換為可用的生物柴油

Well, all these oils and fats you donated

嗯，你捐出的所有這些油和油脂

which produces long-chain esters and glycerol.

這裡有一些常規柴油燃料的分子

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

If you squint, their structures look pretty similar

如果你定睛一看，它們的結構看起來

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

和那些普通柴油的長鏈烴類很相似

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

現在，你可能想知道，是否所有這一切

After all, how much energy can it possibly generate?

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

好吧，如果把所有在紐約 一天當中所扔掉的油脂

it would be enough to power several hundred flights

And let's not forget that using waste oil
