I have recently got into the idea of making my own briquettes for the fire. aswell as the possobility of even selling them! I have heard that you can use coffee grounds, mollases and wax to make them. but i was wondering if you could mix the used grounds with sawdust, add some water and then press them? The recipe for briquettes made from wax, mollases and coffee grounds: http://www.ehow.com/how_5846974_start-fire-coffee-ground-briguettes.html Please help, Thanks!
