The carbonized charcoal of ERDB is more efficient. A three-meal Filipino household needs only 1.69 kilos of ERDB charcoal compared to 3.5 kilos of ordinary charcoal.
Charcoal briquettes of the ERDB technology can be considered a renewable energy (RE) similar to biomass which mostly comes from waste materials. It should receive incentive from RE programs.
Charcoal briquettes are more cost efficient than unprocessed fuelwood.
Unlike fossil fuel (petroleum) energy sources that can be depleted, charcoal production can be replenished much as other RE (solar, wind, biomass).
An ERDB study indicated “charcoal briquettes from wood and non-wood biomass wastes such as leaves, twigs, branches and other cellolusic biomass can lessen wood and wood charcoal consumption of poultry farms, households and domestic business.”
In a project study involving use of 300 kilos per day of biomass waste, ERDB reported investment here results in a 100 percent internal rate of return, making it a very viable business.
“Positive externalities are the potential for carbon sequestration (1.53 million kilos in 10 years), landscape amenities it will provide, protection of biodiversity (flora and fauna), among others,” ERDB said.
The charcoal production from this project is 5.4 million cubic meters (cu.m.) per year fuelwood from the forest and woodlands or an equivalent charcoal of 1.35 million metric tons.
This project will spare 6,970 trees yearly.
