    That's why a team led by Mejdi Jeguirim of France's Mulhouse Institute of Materials Science has taken a different approach. The scientists started by mixing the wastewater with cypress sawdust, which is another waste product that's common in the Mediterranean, where 97% of the world's olive oil is produced.
