“…Modification by metal complexes (FeO 2 ) was found to significantly enhance SC and increase chemical contaminant adsorption rates in a batch experiment [ 82 ]. Similar results by modification with sulfur, chloride, and metal oxides (CuO-ZrO 2 ) are reported [ 83 ]. Because carbon materials including SC possess evenly distributed internal structures, these elements are uniformly dispersed in the matrix structure at the molecular level promoting effective activation.…”

Development of low-cost contaminant sorbents from industrial waste is now an essential aspect of the circular economy since their disposal continues to threaten ecological integrity. Semicoke (SC), a by-product generated in large quantities and described as solid waste from gasification of low-rank coal (LRC), is gaining popularity in line with its reuse capacity in the energy industry but is less explored as a contaminant adsorbent despite its physical and elemental carbon properties. This paper summarizes recent information on SC, sources and production, adsorption mechanism of polluting contaminants, and summarizes regeneration methods capable of yielding sustainability for the material reuse.

“…Moreover, Wang et al (2019b) stated that biochar-immobilized PAH-degrading bacterial strains and Cr(VI)-reducing bacterium was effective in simultaneous bioremediation pyrene and Cr(VI). Specific bacteria immobilized on biochar performed excellent functions of adsorption and biodegradation of organic compounds such as atrazine, nonylphenol and petroleum hydrocarbon, and the removal efficiencies had been apparently improved compared with biochar or bacteria alone (Lou et al 2019;Tao et al 2019;Zhang et al 2019a). Apart from heavy metals and organic compounds, the removal of nitrogen, phosphorus and bioavailable carbon as quantified by chemical oxygen demand (COD) by microorganisms immobilized on biochar also received great attention.…”

Biochar, derived from thermal pyrolysis of biomass, has been regarded as a low-cost, sustainable and beneficial material and widely applied in agriculture, environment and energy during the last two decades. To elucidate the research status timely and future trends in biochar field, CiteSpace is used to systematically analyze the related literature retrieved from the Web of Science core collection in 2019. Based on the keywords clustering analysis, it was found that "biochar production", "organic pollutants removal", "heavy metals immobilization", "bioremediation" were the main hotspots in research covering biochar. "Bioremediation" is an emerging topic and deserves extensive attention due to its highly effective and environmentally friendly treatment of pollutants. Improving the phytoremediation effect, immobilizing functional microorganisms on biochar, and using microorganisms as raw materials to produce biochar were the common methods of biochar-assisted bioremediation. While studies focused on "soil quality and plant growth" and "biochar and global climate change" decreased, investigations concentrated in the toxicity of biochar to soil biota and ruminants are sustainably growing. Research on direct and catalytic thermal pyrolysis of green waste (mainly microalgae) for biofuels (bio-oil, biodiesel, syngas, etc.) and biochar production is increasing. Converting municipal wastes (e.g., sewage sludge, fallen leaves) into biochar through pyrolysis was a suitable treatment for municipal waste and became a popular topic in recent time. Moreover, the biochar produced from these municipal wastes exhibited excellent performance in the removal of pollutants from wastewater and soil. This review may help to identify future directions in biochar research and applications.

“…For instance, it was reported that the addition of biochars could be used to reduce the bioavailability and mobility of atrazine through adsorption-desorption processes which are mainly depending on soil properties (Zhao et al 2013;Mandal et al 2017;Cusioli et al 2019;Ding et al 2019). Indeed, Tao et al (2019) highlighted the influence of soil physical and chemical characteristics, especially pH, CEC, and OM on the adsorption-desorption behavior of pesticides.…”

Biochar in temperate soils: opportunities and challenges

2022

View full text Add to dashboard Cite

Biochar, a carbon-rich material produced by the pyrolysis of organic residues, is frequently used as a soil amendment to enhance soil fertility and improve soil properties in tropical climates. However, in temperate agriculture, the impact of biochar on soil and plant productivity remains uncertain. The objective of this review is to give an overview of the challenges and opportunities of using biochar as an amendment in temperate soils. Among the various challenges, the type of feedstock and the conditions during pyrolysis produces biochars with different chemical and physical properties, resulting in contrasting effects on soils and crops. Furthermore, biochar aging, biochar application rates and its co-application with mineral fertilizer and/or organic amendments add further complexity to our understanding of the soil-amendment-plant continuum. Although its benefits on crop yield are not yet well demonstrated under field studies, other agronomic benefits of biochar in temperate agriculture have been documented. In this review, we proposed a broader view of biochar as a temperate soil amendment, moving beyond our current focus on crop productivity, and instead target its capacity to improve soil properties. We explored biochar’s benefits in remediating low productive agricultural lands, and its environmental benefits through long-term carbon sequestration and reduced nutrient leaching while curtailing our reliance on fertilizer input. We also discussed the persistence of beneficial impacts of biochar in temperate field conditions. We concluded biochar displays great prospective to improve soil health and its productivity, enhance plant stress resilience, mitigate greenhouse gas emissions and restore degraded soils in temperate agriculture.
