摘要

The invention relates to an environmentally friendly oil binding agent based on comminuted plastic or inorganic material, which is obtained for use as an adsorption material from the comminuted plastic or inorganic material and at least one vegetable oil, vegetable oil constituent or vegetable oil derivative. The plastic can be polystyrene, preferably in fine chips, and the vegetable oil is selected from rapeseed oil, sunflower oil, soya oil, castor oil, olive oil, linseed oil, coconut oil, palm oil, a constituent or derivative of said oils and mixtures thereof. In addition, the oil binding agent can contain a filler, such as silica sand. The areas of application for the oil binding agent are manifold and relate to the binding of oil on water, the cleaning of water in harbour basins or similar, in containers filled with liquid, the cleaning of oil-contaminated birds, the binding of oil on street surfaces and sandy soil and the cleaning of oil containers. The invention also relates to a method for disposing of oils of petrochemical or vegetable origin.
