    France Valgo has successfully tested a new method for tannery sludge removal.

    The test was in front of a tower in southwest France.

    Tannery

    The old site.

    Valgo is located in Paris, specializing in soil treatment, especially in cleaning up industrial waste pollution so that it can be reused in particular.

    The company said the key to the success of the new method is to use a plant called geranium (or geranium, geraniums).

    They explained that the use of

    Botany

    Remove soil or waste water.

    Toxic Substances

    It's not a fresh idea. It started decades ago. This process is called plant extraction (phytoextraction).

    Laurent Thannberger, the scientific director of Valgo, told French media that the process of absorbing metal elements through plants was slow.

    In addition, the method of using plant extracts to treat industrial waste has not been launched in large scale in the industry.

    The company also said that before using geranium, they first dissolve metals with solvents, which would make plants better absorb metal elements.

    The solvents they use are easy to obtain, and are widely used in medical and chemical fields.

    The experiment in Tann tannery successfully extracted many metal elements from soil, such as chromium (chrome), copper (copper), lead (lead) and zinc (zinc).

    Mr. Thannberger said his company is now conducting a new experiment to see how different combinations of plants and solvents can produce different types of soil.
