Biochar Production and Uses

Author: Mike Shiralian

Publisher: Journal of Ecology and Environmental Sciences

The Biochar wonders have been known for over the las decade for its many applications in climate change, food security, renewable energy and waste management.
Biochar is carbon rich charcoal produced through thermal pyrolysis (300-700 c) of biomass (organic matters) under little or zero oxygen conditions. The process is similar to backing rather than burning or incinerating, that’s why it also produces mixture of organic gaseous (syngas) and liquid fraction called “wood vinegar” as by-products. The main solid product Biochar has tremendous porous and surface structure which provides great habitant for microorganisms, increases bioavailability, and great reservoir for water nutrients and pollutants which are expected to take hundreds of years to biodegrade. Plantation over Biochar as soil amendment not only increases the rate and size of growth, it also provides an effective carbon sink for sequestering atmospheric carbon dioxide through the leaves, and bio-accumulates the heavy metals from soil (Phytoremediation) via the routes. The syngas is used as energy and the wood vinegar as value added by-products.
