The firelog made from spent coffee grounds.
It was invented in 1998 by Rod Sprules, when one evening at his home, he conducted an experiment where he used dried coffee grounds from his coffee maker filter, combined it with candle wax and then compressed it with a pen into an old cigar tube. It burned so well that he then made prototypes in a loaf pan and gave it to some friends to try…
Java-Logs have a faint sweet scent arising from the mixture of molasses and coffee. Most people don’t smell anything while others smell a faint sweet coffee aroma – no chemical scent.
I wish I thought of this.
