I just read an interesting article where spent coffee grounds are transformed into pellets, both heating (Java Flame) and grilling (JavaBrrewBQ).

 The company, SRG(Sustainable Resources Group) claims a 35% higher BTU output; 11,170 VS 8,100 with 80% less ash.

 Cost wise, a 20 pound bag of the cooking pellets sells for $20.00

 This is new to me. How about you?

 * This didn't work for me. I found their site searching Google. It's interesting!

Never heard of it or the company.

 Perhaps Lew Knows them as they are located in PA ?

I remember my dad saying they would roll cigarettes with used coffee grounds when he was a kid.  I bet that was really bitter but they would certainly burn as pellets.  Not sue of the smoke profile for food though.

Never heard of them but they are an hour from me and right down the street from a record store that I have been planning to visit for the last few years.

Interesting. Not a fan of the flavor of coffee so I wonder what if anything they would flavor the meat when smoking. But for my heating I wouldn't care. I paid 305 a ton for wood pellets delivered this year, the most I have ever paid by far. Can't imagine these would be comparable in cost for heating, but maybe in a few years if the process get out more and more companies get involved.

 Hard to imagine a Pennsylvania company doing coffee grounds in to pellets, I have lived in PA all my 57 years and didn't think coffee was one of the things grown here.

Not sure I would use them.  Imo I wanted a coffee flavor I would prefer to use a coffee rub. 

I guess I would want to know how they bind?  If they are like wood and a natural binder is created when they are extruded under pressure.  Or is something add to bind it.

Tried them.  Smelled like burnt coffee to some burnt popcorn to others.  A few liked them, most did not.  Flavor and aroma are the top qualifiers in my book.

  Thanks Ruff.  That was interesting.  The concept of coffee pellets is a new one; at least to me.

Since I don't like coffee, they won't be found in my pellet supply.
