Biochar: Production, Characterization and Applications
Previous studies have proposed biochar as a natural adsorbent material with potential to be used in the remediation of polluted soils. Its application for adsorption of pollutants may reduce the bioavailability of harmful compounds in the soil media by limiting its chemical distribution and reducing the risk of uptake by organisms. Therefore, biochar has been suggested for the attenuation of heavy metals (HMs) in soil, minimizing the possibility of accumulation through the trophic chain (Figure ).

Biochar: Production, Characterization and Applications
The main objective of this work is to use pyrolysis for the production of biochar from the residues of well-established biochemical processes. The residues that were selected come from two major conversion processes: biogas digesters, and wastewater treatment facilities. These processes produce unconverted lignin-rich residues, made of biomass components that are refractory to biochemical conversion. Pyrolysis is an aggressive thermochemical conversion process that is ideally suited to such residues. The desired biochar characteristics were determined by the specific needs of each industrial partner. The desired traits for the biochar obtained from sewage sludge were the capture, and stabilization of heavy …

Biochar: Production, Characterization and Applications
The use of biochar, a secondary product of pyrolysis after syngas and bio-oil production for bioenergy, is promoted for agricultural purposes. Its potential for C sequestration and greenhouse gas emission reduction can help for mitigating climate change and potential adverse impacts to ecosystems. Additionally, it represents an alternative means for containing water and atmospheric pollution ascribed to large volumes of crop and animal wastes. As a soil amendment, biochar has received increased interest due to its role in enhancing nutrient- and water-use efficiencies.
