Biochar From Fruit Waste Removes Toxic Wastewater Pollutants
Biochar made from fruit waste like pineapple crowns and sweet lime fibers takes center stage in the newly developed method designed to eliminate toxic pollutants in industrial wastewater.
Using the pyrolysis process, researchers at the Indian Institute of Technology Guwahati (IIT Guwahati) discovered the potential of the carbon-rich material to effectively absorb nitroaromatic compounds, which are harmful to human health and ecosystems. In addition to these compounds, biochar can remove hazardous chemicals in wastewater, such as dyes, pesticides, cosmetics, and pharmaceuticals.
According to IIT Guwahati, the research team created two kinds of biochar: ACBC (ananas Comosus Biochar) and MFBC (Citrus Limetta Biochar). Then, they assessed both biochars' capability to remove a common nitroaromatic pollutant found in industrial wastewater called 4-nitrophenol.
On top of this, they also discovered that the biochar can be reused in multiple types, making it a sustainable, low-cost way to clean wastewater:
"Both ACBC and MFBC retained their high performance over multiple cycles, meaning they can be reused several times without losing effectiveness. This feature makes the approach not only sustainable but also economically viable for industries looking for long-term wastewater treatment solutions."
The team sees their method will perform well in real-world applications. As a filtration system, the biochar can be integrated into water purification setups for rural communities. It can also help restore waters and soils affected by industrial discharge, proving to be a viable and vital addition to current environmental solutions.
The institute emphasized:
"With its combination of low-cost production, high efficiency, and sustainability, this approach offers a promising alternative to conventional wastewater treatment technologies."
Before starting full-scale commercial production, the biochar method will undergo several stages of lab-scale testing, field trials, and market validation.
