At a method of in situ recovering and rendering harmful material detrimental to environment, for example asbestos and the like, the material is transported together with ambient air by means of vacuum from the place in situ to a space (3, 4), in which the material is separated from the air, which is led off upward, filtered and removed. The material is moved from the space (3, 4) and sprayed and/or injected, at (12), with a substance permanently binding the material, and the material, thus bound in the form of manageable units, is removed intermittently or continuously from the spaces. |
