Charcoal is widely used as a biofuel for cooking and industrial purposes, but its ignition requires safe materials known as Charcoal-Ignition-Aiders (CIA), which can emit harmful gases.
A study found that using paper as a CIA resulted in the lowest carbon monoxide emissions, though all CIA options resulted in volatile organic compounds exceeding safety standards.
The research highlighted significant differences in charcoal usage based on socio-demographic factors, recommending a combination of wood from specific trees and paper for safer and more efficient combustion.
