As winter approaches and the temperature inches closer to zero and below, there's nothing quite like curling up by a fire. When purchasing a log for the fire, you'll be surprised to find that soy plays an integral part in the log's usage. FarmedFuels developed a fire log called SwitchFire, made up of 50% soy. The soy wax causes the log to burn cleaner which reduces levels of residue, and makes the log burn slower. The slow burn helps keep the house warmer for longer periods of time.
