Estate Crops News – Kenaf is a natural fiber crop that have a lot of diversified products with high economic value and environmental functions. Kenaf contribution to the environment is also known through a high ability to absorb carbon dioxide. Carbon dioxide (CO2) gas is the main anthropogenic contributor to the greenhouse effect.
Carbon sequestration by plants became one of the most important steps to greenhouse gases mitigation. The high absorption of carbon dioxide by kenaf affected by the high photosynthetic rate, although kenaf belongs to the group of C3 plants. Kenaf photosynthetic rate supported by high RuBP carboxilase activity, high stomatal conductance, and high plant biomass production. Kenaf photosynthetic rate reaches 3-8 times higher than trees and other C3 plants. Based on biomass produced, kenaf ready for harvest on 4-5 months plant age saved 2,9-12,1 tonnes C/ha or absorb 21-89 tonnes CO2/ha/year depending on the agronomic management and environmental conditions. Nowadays, land area of kenaf in Indonesia is approximately 3000 ha, therefore the absorption of CO2 reaches about 63-267 million tonnes/year. As well as carbon sink in long time, some kenaf diversified products such as car interior and automobile components, sound absorber, and pulp and paper also contribute to reducing CO2 emissions through savings of energy and decreasing deforestation rate and other harmful gas emissions. Development of kenaf plantation is expected to help the Indonesian government in an effort to reducing greenhouse gas emissions as well as providing the raw materials of natural fiber for environmentally friendly industrial raw materials.
