- Charcoal is produced by heating wood in the absence of oxygen, off-gassing water and volatile compounds, leaving behind flammable carbon residue.
- Greenhill Forge demonstrates a self-sustaining charcoal production system using a metal retort and waste heat for hot water generation.
- Charcoal can be used for cooking, heating, and electricity generation, forming part of a carbon-neutral off-grid system.
- Wood gasifiers, like downdraft gasifiers, efficiently convert wood into syngas, with designs improving fuel economy and reducing emissions.
- Bamboo is a faster-growing renewable resource compared to wood, with bamboo fuel pellets offering competitive combustion properties.
- Bamboo ash contains higher silica content than wood ash, posing health risks, but bamboo pellets are still a viable fuel alternative.
- Wood and bamboo have different energy contents, with bamboo sometimes outperforming pine in calorific value for pellet production.
