Nutrients and Heavy Metals in Biochar Produced by Sewage Sludge Pyrolysis: Its Application in Soil Amendment
The production of sewage sludge has been sharply increasing by municipal sludge treatment plants in China. Sewage sludge is a difficult waste to manage not only due to the high quantities produced but also due to its high concentration of heavy metals and pathogens. The pyrolytic conversion of sewage sludge to biochar and then applied to the land is a sustainable management potion. Therefore, t...
متن کاملProduction and characterization of Biochar from Various Biomass materials By slow Pyrolysis
Biochar is the carbonaceous solid product of biomass pyrolysis which can be used as chemical feedstock for various purposes such as energy production, and adsorption of pollutants. In particular, application of biochar to the soil is gaining greater interests, which can reduce fertilizer consumption, increase crop yields, and sequestrate carbon. This study compares the characteristics of biocha...
متن کاملChloropicrin Emission Reduction by Soil Amendment with Biochar
Biochar has sorption capacity, and can be used to enhance the sequestration of volatile organic contaminants such as pesticides in soil. Chloropicrin (CP) is an important soil fumigant for the production of many fruit and vegetable crops, but its emissions must be minimized to reduce exposure risks and air pollution. The objective of this study was to determine the capacity of biochar to adsorb...
متن کاملEffects of biochar amendment on soil aggregates and hydraulic properties
The aim of this study was to investigate the effects of biochar amendment on soil aggregate formation and stability, and soil hydraulic properties. Biochar produced from dairy manure was added to two different soils (a silty clay and a sandy loam soil) at a ratio of 2% (w/w in dry weight basis). Incubation experiments were conducted within a 90-d period with the soils (the controls) and the soi...
متن کاملEstimating Profitability of Two Biochar Production Scenarios: Slow Pyrolysis vs. Fast Pyrolysis
We estimate the profitability of producing biochar from crop residue (corn stover) for two scenarios. The first employs slow pyrolysis to generate biochar and pyrolysis gas and has the advantage of high yields of char (as much as 40 wt-%) but the disadvantage of producing a relatively low-value energy product (pyrolysis gas of modest heating value). The second scenario employs fast pyrolysis to...
