Anthracite - coal dust - is a binder that is becoming more popular in use. One of the advantages to briquetting is that it can use lower quality wood sources (i.e. not large pieces of expensive hardwood), meaning that more charcoal can be produced per unit of felled tree area. The core concept behind charcoal is the idea of carbonisation.
