They brought with them the technology for melting and smithing iron. Arab-Swahili slave traders and their captives on the Ruvuma River From the late first millennium AD, vast Indian Ocean trade networks extended as far south into Mozambique as evidenced by the ancient port town of Chibuene.

Vesterberg, Jessica, Wood pellet as an alternative cooking fuel in Mozambique : emission performance of a wood gasification stove. First cycle, G2E. Uppsala: SLU, Dept. Combustion of solid biomass is a significant source of particulate and carbon monoxide CO emissions.

Not only has the increasing demand of charcoal and firewood lead to an escalation of deforestation, but also the emissions from the combustion of the fuels are highly correlated to harmful health effects. Mozambique has vast natural recourses, especially forestland. The established wood processing industry in the country produces large amounts of by-products that could be compressed to the dense and high calorific fuel, wood pellets.

This study compares the particulate and carbon monoxide emissions generated from wood pellets, birch firewood and torrefied bamboo pellets, when combusted in wood gasification stoves WGS. Furthermore interviews were conducted with households and wood industry companies to investigate the possibility of introducing wood pellets in combination with WGS. The preferred fuel among the households was the torrefied bamboo pellet because of its smooth burning characteristic.

Wood pellets had high flames, easily burning food. The laboratory tests showed that wood pellets had the lowest emissions of both CO and particulate matter PM. The stove was adjusted in order to lower the CO and PM emissions, but the results from laboratory tests did not show any substantial differences. However, considering user friendliness, rotating three of nine bottom tiles in order to decrease the primary airflow in combination with expanding the upper tiles from 4.
