Now press the pulp, dry it for two to three days and what you have is your briquette, all ready to burn in a range of stoves ranging from mud stove with one burner to rocket stove and room chimneys. It is energy efficient, cost-effective, manages waste and moreover an inexpensive alternate source of energy that can fuel simple households to business houses.
