A group of seventh-grade students from a school in central Israel has made a unique breakthrough in water-filtering technology by using tire crumbs, ground pieces of rubber made from scrap car and truck tires.

The Harel School students

The 13-year-old students from the Harel School in Lod have registered their patent in the U.S., and now Mekorot, Israel’s national water company, is interested in their innovative technique as a water-filtering solution for developing countries.

“Tire crumbs are surprisingly effective in their role as a filter,” one of the students said. “Tires are a readily available item, and are usually thrown away and pollute the environment.”

“The students did an amazing job and one can see the start-up mindset in them,” Harel School teacher and high-tech executive Eyal Lipchitz said.

Mekorot Vice President of Quality and Information Systems Yaffa Farber said the company was “happy to work with the students and give them professional assistance and guidance; we will examine their discovery in depth.”
