The First House Powered by Coffee

Since 2006, Dunkin’ Donuts has used the tagline “Amer­i­ca Runs on Dunkin’,” pre­sum­ably allud­ing to the cof­fee and donuts that get mil­lions of Amer­i­cans through each morn­ing. But maybe, all along, they’ve had some­thing more in mind. Above, Dunkin’ presents a tiny home pow­ered by bio­fu­el made from spent cof­fee grounds, a process mas­ter­mind­ed by a com­pa­ny called Blue Mar­ble Bio­ma­te­ri­als. Work­ing with lux­u­ry tiny home­builder New Fron­tier Tiny Homes, they’ve cre­at­ed a process–notes a Dunkin’ press release–that works some­thing like this:

  • Step 1: Extract excess oils in the spent cof­fee grounds. There can be nat­ur­al oils left in spent cof­fee grounds, all depend­ing on the cof­fee bean type and orig­i­nal pro­cess­ing meth­ods.
  • Step 2: Mix and react. These oils are then mixed with an alco­hol to under­go a chem­i­cal reac­tion known as trans­es­ter­i­fi­ca­tion. This pro­duces biodiesel and glyc­erin as a byprod­uct.
  • Step 3: Refine. The biodiesel is washed and refined to cre­ate the final prod­uct.

When all is said and done, 170 pounds of used cof­fee grounds trans­lates into one gal­lon of fuel. From 65,000 pounds of cof­fee grounds, you got enough juice to pow­er a 275 square foot home, at least for a while.

Take a 360 degree inter­ac­tive tour of the tiny home here.

    Cool, but I hope it nev­er takes-off. His­to­ry has shown when food becomes a source of fuel, it expo­nen­tial­ly dri­ves the costs of those sta­ples up; and the effect hurts the poor who use that same prod­uct at the end-of-the-day…leave our cup of morn­ing-joe alone, it’s thank­ful­ly cheap for now!

    Fake news. My house­hold has been pow­ered by cof­fee for decades.
