Waste Coffee Grounds Offer New Source of Biodiesel

Julie188 writes "Researchers in Nevada are reporting that waste coffee grounds can provide a cheap, abundant, and environmentally friendly source of biodiesel fuel for powering cars and trucks. Their study has been published online in the Journal of Agricultural and Food Chemistry. Growers produce more than 16 billion pounds of coffee around the world each year. Scientists estimate that spent coffee grounds can potentially add 340 million gallons of biodiesel to the world's fuel supply."

won't somebody think of the mornings?

and as the price of bio-diesel goes up, so does the cost of our coffee. Eventually, none of us will be able to wake up at all.

Caffeinated Diesel?

[Ssherby]

I want my coffee to be unleaded, and my bio-diesel to be caffeinated.

I don't even want to think about how much a gallon of Starbucks biodiesel would cost.

Save the world, become a geek!

[the_xaqster]

Yay! /. will supply 80% of the worlds Biodiesel!

Re:shipping cost

[stranger_to_himself]

..It's sort of like future gas stations will make their own biodiesel or at least get it from a supplier within 25 miles in like 80% of populated US cities or something close to that...

And in the unpopulated cities they have to rely on imports because the undead don't drink coffee.

Big Deal?

[JRSiebz]

I've been putting coffee grounds in my Mr. Fusion for years.

[Accursed]

Given the taste of their coffee, it would likely come pre-burnt anyway.

You tell me, is $60.00 bigger than $4.00? It's been a while since I took arithmetic but I seem to remember that this is so

Confirmation on that, chief. $60 is more than $4.

And it all seemed to work just fine, until the Juan Valdez oil spill...

[sleeponthemic]

But I thought less was more?

It was, but it grew and now it is more or less more than less.

Most of the world uses the 24 hour clock. 2010 is just before quarter past 8pm.

HTH HAND.

Bullshit!

Dude, he's a "former logistics and process consultant". He's way ahead of you.

They can't sell them fast enough because everyone is out of a job 8*)

OPEC member here I come

[olddotter]

My coffee habit should get me on a list of major Bio-diesel feed stock suppliers. :-)

And I would have gotten away with it too, if it wasn't for those meddling kids.

Sounds like grounds for excitement!

[Slicebo]

:)

Instant?

[WED Fan]

What would certainly get more expensive is instant coffee, because that doesn't produce waste coffee grounds.

Instant bio-diesel? 2 scoops of powder, add water. Cream? Sugar?

So, if you don't want the exhaust to smell like your breakroom after the dipshit from IT grabbed the pot off the hotplate while it was still dripping, do we want to add Irish Creme to the mix?

Will they someday insist that we switch to decaf biodiesel to protect the environment? Do I have to stop telling the Barista to make mine leaded?

Since my cardiologist told me to cut down on caffeine, do I have to avoid traffic jams?

Is Ford going to come out with a special "Juan Valdez" edition Explorer?
