Biocarbon for Sustainable Water purification

Abstract

Global environmental challenges including environmental pollution, water scarcity, climate change, are nightmares to the human society. Research and development in the field of water research paved the way to utilize sustainable materials for water purification and the currently available innovative technologies are capable to purify the water as per the World Health Organization standard. But the main drawback of these technologies is the huge cost associated with it. In this context, biocarbon is a sustainable material, which exhibits peculiar properties such as environmentally friendly, low cost, naturally abundant, easy to process, etc. to name a few. As per the goals set by the United Nations, the Sustainable Development Goal 6 deals with Clean Water and Sanitation. A suitable solution for global freshwater requirement by purifying the contaminated water resources using biocarbon is in high demand. A review report in the field of biocarbon based water purification is lacking in the literature. This motivates us to write this review on biocarbon based water purification. We discuss the synthesis, properties, and water remediation measures of eco-friendly biocarbon and other biocarbon-based materials. This review opens up a new paradigm shift in the water purification technologies which are sustainable, eco-friendly and cost-effective when compared to that of the available technologies.
