Scientists at IIT Guwahati have found a new way to clean dirty industrial water using waste from fruits like pineapple crowns and mosambi (sweet lime) fibers. This low-cost and eco-friendly method removes 99% of toxic pollutants from wastewater.
How It Works
The researchers used a process called pyrolysis, which breaks down organic waste to create biochar, a carbon-rich material. Two types of biochar were tested:
-
ACBC (Ananas Comosus Biochar) from pineapple crowns – removed 99% of pollutants.
-
MFBC (Citrus Limetta Biochar) from mosambi fibers – removed 97% of pollutants.
This method works quickly, in just five minutes, and the biochar can be reused several times without losing its effectiveness.
Why It’s Important
Traditional water treatment methods are expensive and complex. This new solution is cheap, effective, and sustainable, making it easier for industries to clean their wastewater.
Future Plans
The scientists are now testing this method for clean drinking water in rural areas and environmental clean-up projects. They are also working on large-scale production and commercial use.
Dr. Gopal Das, who led the research, said, "This work shows how waste materials can be turned into valuable resources to fight pollution."
With its low cost, high efficiency, and environmental benefits, this method could replace expensive water treatment processes in the future.
