Role of Biochar from Gasification Technology in Carbon Sequestration

GHG

Biochar helps reducing concentration of GHG required to slow down global warming & climate change
Highly stable against microbial decomposition and hence reduces GHG emissions

Soil Enhancement

For greenhouse mitigation, application of biochar into the soil is gaining popularity due to several advantages.
Increase in crop yield, nutrient and water use efficiency and several environmental benefits.

Fixed Carbon + Yield

Biochar generated from Gasifiers contains around 75 to 85% of fixed carbon that can be returned to the soil
The yield could vary from 6% to 25% of feed by weight, depending on the type of biomass and design of Gasifier

Biochar charcoal

Tar powder

Farm

Biochar is a highly stable form of carbon derived from pyrolysis & gasification of biomass

Helps reducing the concentration of GHG

Biochar into the soil provides benefits like increase in crop yield, nutrient and water use efficiency and several environmental benefits

Biochar generated from Gasifiers contains around 75 to 85% of fixed carbon that can be returned to the soil. The yield could vary from 6% to 25% of feed by weight, depending on the type of biomass and design of Gasifier

Charcoal can be used for cooking in rural areas or for any thermal heat applications.
