What’s the best materials for making charcoal briquettes

Good raw materials are the basis for the production of high-quality charcoal. In theory, many biomass can be used to produce charcoal, such as sawdust, bamboo powder, rice husk, bagasse, and so on. But it needs to be clear that under the same conditions, the quality of the carbon produced by different materials is different. So what is the best raw material for making charcoal? Studies have shown that ash content directly affects the combustion performance of biomass charcoal. The lower the ash content, the better the combustibility of charcoal. The data tested by agricultural experts show that: coconut shell ash content is 0.61%, sawdust ash content is 0.9%, cotton stalk ash content is 5.1%, rice husk ash [...]
