Biochar application for nutrient recirculation
2019-01-09 21:40:24

 Recently, the use of biochar has been recognized as an environmental remediation due to its carbon sequestration effect, nutrient buffering capacity, and benefit of biomass recycles. Among many strengths, the interest in nutrient recovery capacity of biochar has increased. Since biochar can hold nutrient in several media including soil, groundwater, and wastewater, it can be used for removal of excessive nutrients in environmental media, which are severe concerns on eutrophication or drinking water quality. Given the nature of adsorption-desorption system, adsorbed nutrients then can be transferred to other media with insufficient amounts of nutrients. In this study, the potential and efficiency of nutrient recirculation by biochar made up of a variety of feedstocks.
