Special Issue on Biochar Technologies, Production, and Environmental Applications in Critical Reviews in Environmental Science and Technology during 2017–2021
As an environmentally friendly and carbon-neutral material, biochar is one of the most promising candidates for effective mitigation of soil remediation and water/air purification. Researchers emphasized the importance and necessity to standardize biochar characterization and recommended the initiation of a global forum for biochar characterization. Among soil applications using biochar-based materials (i.e., heavy metal immobilization, greenhouse gas emissions, and plant productivity), systematic research is necessary to fully improve soil conditions suitable for water and air purification. In addition, because biochar is listed in the NETs, a biochar-based carbon-neutral technology roadmap is urgently needed, which helps to achieve carbon neutrality by 2050. With concerted efforts on the production and application of biochar and biochar-based novel materials, we are likely to achieve the circular economy and some sustainability goals set by United Nations. This special issue aims to summarize the papers published in Critical Reviews in Environmental Science & Technology (CREST) during the past five years (2017 to 2021).
