Israel’s Innovative Soil Cleaning Process

An Israeli research team from the Hebrew University of Jerusalem has developed a new process for cleaning contaminated soil.
Using cement mixers as giant green laundry machines, their cleaning formula whisks dangerous materials away from the soil, leaving desirable minerals intact.

“What this process enables is to extract both organic dirts, like oil, pesticides and so on, and heavy metals, in one step. Within few minutes we extract everything.”

Lab technicians demonstrate the novel cleaning process. They pour contaminated soil into a mixer that contains hot water. Then they add their new cleaning agent that binds to heavy metals and extracts them. While the liquid inside the mixer cools down, it starts to separate into two different phases. After pouring the liquid into a filter, the darker, more dangerous materials are extracted, leaving clean soil in the filter.
Doctor Ludmer says the process is economically efficient and unique compared to current methods of cleaning soil.
[Dr. Zvi Ludmer, Developer]:
“We are dealing with very contaminated soils which contain both organic impurities or contaminants, and heavy metals. Now, since this is a process that we do in one step and no one else does it the way that we do it, it is very economic.”

This formula would greatly benefit properties close to industrial parks as soil contamination can cause groundwater pollution and be a health hazard.
