About the book
Biochar is a carbon-rich material produced when biomass, e.g., wood, manure or leaves is burned at a relatively low temperature < 700 ºC in a zero or low oxygen condition. Biochar has received great interest during the last few years, due to its beneficial role to mitigate CO2 emission and to improve soil quality. In addition, biochar has proven to be a suitable tool for remediating Potentially Toxic Metals (PTMs) contaminated soils and water. However, some studies showed that biochar may alter the availability of some heavy metals, i.e., As, Cu and Cr in contaminated soils. Therefore, intensive studies are needed to investigate the effect of biochar on the availability of heavy metals in single and multi-contaminated soils. This study will focus on the historical view of biochar production and applications. Its beneficial role for soil fertility improvement. In addition the use of biochar for decontaminating water and soils from organic and inorganic contaminants. The major effects of biochar for heavy metals bioavilability will be a matter of concern. In addition, we will highlight the feasibility of using biochar in combination with phytoremediation and soil washing technologies; consequently, more remediation efficiency can be targeted. These are all important topics that we will seek to cover in the book.
