Bio-Char Used for Carbon Sequestration and to Balance the CO2 Concentration in Atmosphere: A Review

Abstract

Abstract: The Carbon concentration in earth is closed system, therefore, the contain of carbon in each elements are different. The concentration of CO2 in atmosphere is lower compared with N2 and O2 gas but CO2 concentration is great effect to the atmosphere temperature, it may cause the global warming and climate change.  The CO2 concentration in atmosphere should be maintained to slower increase in order to reduce the effect of CO2 in atmosphere.  Balancing of carbon positive and negative is concerned to maintain the CO2 concentration in atmosphere. Bio-chars are materials carbon that can be used as soil amendment to increase crop production. Recently, the carbon positive more than the carbon negative, resulted the CO2 concentration in atmosphere was increased gradually. Biochar has been possibility to produce in a large quantity to utilize of waste biomass.  We needs a large quantity of biochar to be   produced and mixed with soil and store in the ground as carbon sequestration, those biochar increase the soil fertility. Scenarios stabilization wedge represents an activity that starts at zero reduction of emissions in 2005 and increase linearly until it accounts for 1 GtC/ year or 1 wedges reduced carbon emissions in the year 2055.
