In the realm of global environmental challenges, the control of pollution emerges as a paramount task for nations striving to maintain environmental sustainability. Amidst various approaches, biochar, a processed carbon material, has garnered considerable attention for its active functional groups that contribute to the removal of environmental pollutants, mitigating potential hazards. This has led to a surge of interest in the development of highly productive biochar for applications in environmental engineering.

However, a notable gap exists in comprehensive literature exploring the science of biochar and its broad potential applications. Recognizing this void, a recent review aims to address the deficiency by delving into key aspects of biochar, including its fundamentals, engineering modifications, and promising environmental applications. With a primary focus on water treatment, the review underscores the significance of biochar in the environmental remediation process.

This overview serves as a valuable resource for researchers, policy-makers, and stakeholders, offering insights to plan and evaluate scientific endeavors. By emphasizing the importance of customized biochar production for future environmental applications, the review advocates for a holistic approach to combat pollution and foster sustainable environmental practices.
