Special issue on biochar technologies, production, and environmental applications in Critical Reviews in Environmental Science & Technology during 2017-2021

The engineered biochar has been extensively developed for environmental applications in the last decade, owing to its carbon-neutral and long-term persistent characteristics. Here, we addressed the advancement in production of novel engineered biochar with practical environmental remediation, and pointed out key challenges and future perspectives, based on total 28 publications in Critical Review in Environmental Science and Technology during 2017-2021. Without concerted efforts on engineered biochar-based environmental application integrating systematic research and environmental impact assessment, we are unlikely to achieve the circular economy-guided sustainable development.

Automated summary

Engineered biochar has made significant progress in environmental applications over the past decade, but achieving sustainable development guided by a circular economy requires integrated systematic research and environmental impact assessment.
