The aim of the invention is to provide a method by means of which mineral oil contaminations can be removed in an environmentally sound and cost effective manner. Said method should above all cause no additional ecological damage and should be easy to apply. Another aim of the invention is to provide a use for hemp. The first aim is achieved by sprinkling dried hemp onto the surfaces that are contaminated with mineral oil and by severing the hemp and the oil together. The second aim is achieved by using dried hemp as an adsorption agent for mineral oil or mineral oil products.
L'invention concerne un procédé dont le premier objectif est d'éliminer, d'une manière non polluante et peu coûteuse, la contamination par les huiles minérales. Le procédé ne doit pas entraîner des nuisances supplémentaires et être facile à mettre en oeuvre. Le second objectif est de constituer un moyen d'utiliser le chanvre. Le premier objectif est satisfait par le fait que l'on saupoudre de chanvre sec les surfaces contaminées par une huile minérale et que l'on enlève ensuite l'huile avec le chanvre. Le second objectif est satisfait par l'utilisation de chanvre sec comme moyen d'adsorption de l'huile minérale ou des produits à base d'huile minérale.
