Bamboo charcoal begins as one of the fastest-growing plants on Earth and ends as a carbon skeleton whose internal surface can rival a tennis court per handful. Moso bamboo (Phyllostachys edulis) can extend close to a metre per day during peak shoot growth and reaches harvestable maturity in roughly four to five years. Feed that culm into a kiln, starve it of oxygen, and the chemistry of pyrolysis takes over: - 200 to 300°C: hemicellulose decomposes, releasing water and acetic acid - 300 to 400°C: cellulose breaks down, driving off volatiles and tars - 400 to 600°C: lignin degrades and aromatic carbon rings begin to condense - Above 700°C: hydrogen and oxygen are largely expelled, leaving a carbon content typically above 85 percent What makes bamboo distinctive is the template it leaves behind. Its vascular bundles, parenchyma cells, and pits survive carbonisation as an aligned, hierarchical pore network. Macropores act as transport highways, mesopores as distribution channels, and m...
