“…Additionally, it has been applied to soil characterization to assess proportions of labile and recalcitrant organic matter (Plante et al, 2009) and to study the evolution of organic matter in amended soils (Barriga et al, 2010;Gascó et al, 2012). Thermal analysis has the advantage of providing information about the chemical characteristics of soil organic matter without any extraction step as all samples were analyzed.…”

Factors driving the carbon mineralization priming effect in a sandy loam soil amended with different types of biochar

Abstract. The effect of biochar on the soil carbon mineralization priming effect depends on the characteristics of the raw materials, production method and pyrolysis conditions. The goal of the present study is to evaluate the impact of three different types of biochar on physicochemical properties and CO 2 emissions of a sandy loam soil. For this purpose, soil was amended with three different biochars (BI, BII and BIII) at a rate of 8 wt % and soil CO 2 emissions were measured for 45 days. BI is produced from a mixed wood sieving from wood chip production, BII from a mixture of paper sludge and wheat husks and BIII from sewage sludge. Cumulative CO 2 emissions of biochars, soil and amended soil were well fit to a simple first-order kinetic model with correlation coefficients (r 2 ) greater than 0.97. Results show a negative priming effect in the soil after addition of BI and a positive priming effect in the case of soil amended with BII and BIII. These results can be related to different biochar properties such as carbon content, carbon aromaticity, volatile matter, fixed carbon, easily oxidized organic carbon or metal and phenolic substance content in addition to surface biochar properties. Three biochars increased the values of soil field capacity and wilting point, while effects over pH and cation exchange capacity were not observed.

“…The paper industry is of great environmental importance due to the quantity of paper sludge generated, and its disposal. Although a small part of How to cite this paper: Wajima, T. (2017) Preparation of HCl Gas Sorbent from Pa-paper sludge is used as a soil improver and fertilizer in agriculture [4] [5] [6] [7] [8], most of paper sludge is usually disposed of in open dumps or in landfills after incineration. Recently, reduction of available landfill space increasing costs of land disposal of waste in industrial countries necessitates other means for the disposal of waste paper sludge.…”

Preparation of HCl Gas Sorbent from Paper Sludge

Paper sludge (PS) is generated as an industrial waste during the manufacture of recycled paper products, and amounts discharged globally are increasing annually. On the other hands, hydrogen chloride (HCl) is an acidic pollutant that is present in the flue gases of most municipal and hazardous waste incinerators. In this study, the removal of hydrogen chloride gas using the product from paper sludge at high temperatures (700˚C) using a fixed-bed flowtype reactor was investigated. PS can be granulated with distilled water using granulators, and the particle shapes can be kept after calcination and alkali reaction. Calcined PS and the product after alkali reaction of calcined PS have amorphous phases and katoite (Ca 3 Al 2 (SiO 4 )(OH) 8 ) phase, respectively, and both of these indicate HCl removal ability at high temperature (700˚C). The product from calcined PS via alkali reaction has higher HCl fixation ability (78 mg/g) than calcined PS. Removal experiments for HCl gas showed that the removal process followed pseudo-second-order kinetics rather than pseudofirst-order kinetics. These results suggested that the product particles with HCl gas removal ability at high temperature can be prepared from PS using calcination and alkali reaction.

“…[17][18][19][20] In recent years, paper sludge has been suggested to be a potential soil remediation for metal-contaminated soils. [21][22][23] Paper sludge, a municipal solid waste produced by the paper industry during papermaking and wastewater treatment, contains abundant organic matters (i.e. cellulose fibers) and inorganic matters (i.e.…”

Chemical Speciation & Bioavailability

Heavy metal contamination of soil poses risks and hazards to environment and human being. Many amendments were used to remediate the contaminated soil. In this report, paper sludge was used to reduce the bioavailability of Pb in soil, and the remediation mechanism was studied by investigating the redistribution of Pb speciation after paper sludge addition. In pot experiments, significantly increased weights of shoots (from 1.6 to 3.3 mg per plant) and roots (from 0.7 to 0.8 mg per plant), as well as significantly decreased Pb content in shoots (from 153.8 to 24.4 mg kg ) of rape were observed after paper sludge was added. The addition of paper sludge resulted in redistribution of Pb from the liable fractions (carbonate-bound Pb from 58.3 to 3.7%) to the Fe-Mn oxide-bound fraction (from 29.2 to 74.9%). Paper sludge addition increased the content of organic matters and pH of soil, and induced Pb redistribution, which ultimately inhibited Pb uptake and improved plant growth.
