What are the common patterns of growing bamboo:
- • Unlike most species of trees, a bamboo forest can reach full maturity in a single growing season of 3-4 months.
- • A bamboo culm can be ready to re-harvest in a mere 3-5 years; an equivalent stand of paper pulp trees take 50-100 years.
- • Bamboo can also be harvested without killing the plant’s core that produces the collectible stalks, meaning that soil erosion is reduced throughout the harvesting process.
- • These rhizomatic cores are part of the reason why bamboo can grow so quickly. Because the individual stalks don’t need to grow leaves to produce energy for themselves, the stalks can grow upwards at a truly rapid rate, fed by the energy of the central core.
- • The fast growth and storage of carbon in the roots secures a high CO2 sequestration which is known to be 3-4 higher than for example of pine trees.
It’s quite possible to harvest from the same culm of bamboo sustainably, without disturbing the local soil ecosystem or continuing to clear cut wild forest to provide more agricultural land. The bamboo will grow on degraded land as well, with special for irrigation.
This way the bamboo grown is a perfect sustainable feedstock for renewable energy purposes. Besides the positive environmental impact, the technical characteristics of bamboo are equal to wood from trees, meaning a high NCV, low ash, low moisture and in line with the requirement for elements like Chlorine.
