<p>The present invention relates to a method for rendering used fluorescent tubes and other mercury-containing crushable waste products harmless, wherein the waste is treated in a closed container while reducing the amount of mercury therein by ventilating the container and passing the ventilation gas flow through a filter which is capable of effectively capturing mercury. According to the invention, the waste products are heated to a temperature at which the mercury enclosed in the waste products is effectively vapourized, whereafter the waste products are fragmented or crushed in the closed container so as to release the mercury vapour and allow said vapour to spread in the container, whereafter the container is ventilated and the mercury vapour captured by said filter.</p> |
