Do you add any other ingredients to your briquettes apart from coconut shell charcoal?

We only use coconut shell charcoal and approximately 4% of a natural, eco-friendly binder such as tapioca starch to make our briquettes. Nothing else! No nitrates, no borax, no lime, no sawdust or even wood charcoal. Thus our briquettes do not give off any foul odors or smoke during lighting or burning making them a healthier choice compared to traditional quick light charcoals.
