Abstract:
Environmental pollution control in the growing world is a challenging task for all the
countries in order to keep the environmental sustainability. Biochar, a processed carbon material,
draws a significant attention in the field of environmental remediation, as of its active functional
groups that help remove environmental pollutants to a level insignificant to cause hazardous
effects. As such, there is an increasing interest developed to promote highly productive biochar for
exploring environmental engineering aspects. There is limited comprehensive literature available
for understanding biochar science and its potential applications under an umbrella. This review
was set to fill this knowledge gap by discussing key points related to biochar, its novel engineering
aspects and potential environmental applications. Therefore, this overview tends to summarize and
discuss biochar, its fundamentals, engineering aspects commonly used modifications and the
potential applications of biochar in water treatment with an intention of addressing the importance
of biochar for environmental remediation process. This overview will be useful for researchers,
policy-makers and stakeholders to plan and review relevant scientific works in order to produce
customized biochar for future environmental applications.
