Plant-based water-filtration system extracts arsenic from water

LONDON — The system, designed by Oxford University student Stephen Goodwin Honan, has been named the “idea that will change the world” at yesterday's Global Design Forum.


LONDON — A water-filtration system, designed by Oxford University student Stephen Goodwin Honan, uses plants to remove arsenic from water supplies, and yesterday it was voted the "Idea that will change the world" at the Global Design Forum in London, Dezeen Magazine reported.

The Sept. 17 story said Honan's Clean Water invention uses arsenic-absorbing plants to remove the arsenic, which is then trapped in a filter, posing no danger to the environment. The plants are a naturally occurring species, the story stated.

Honan stated in the story that his invention, priced at $10, is an environmentally-friendly, low-cost, easy-to-use filtration system "that rapidly accumulates arsenic from drinking water. The arsenic is able to then be recycled for productive purposes such as semi-conductors, solar panels, cellphones, computer electronics."

According to it website, The Global Design Forum is a platform for people looking to protect and help human society.

"We already have 500 people who've signed up for the next iteration of the pilot project," Honan stated in the story. "They actually approached us to do the next phase. We're then looking to partner with a semi-conductor company and hopefully we can close that gap and do the recycling in plants that are on the ground [in Bangladesh] and produce the first batch of 'responsible arsenic'."
