Scientists in Japan have come up with a new ‘biomass charcoal heater’ that uses the conventional coal heater but without the traditional coal. The new coal they developed contains a variety of waste material including trimmings from an oak tree, coffee waster, and soybean fiber. In relation to other biomass heaters in Turkey and the United States, this bio-heater is 60-80 percent more efficient. This heater could lead to increased efficient and cost savings in home heating.
