Method and apparatus for making asbestos-containing waste inert.

摘要

The following steps are provided: reducing the volume of the waste contained in metal drums or in flexible bags of polypropylene to a volume of about 1/4 of the initial volume, with previous homogenizing in case of flexible big bags, thus providing cakes of consistency and solidity comparable to those of the traditional building materials; arranging the cakes into containers of reinforced concrete and casting within the latter a filling and sealing mortar giving the end product characteristics of mechanical strength and inclusion of material such as to allow the end product to be disposed to dumping-places of the type 2A according to the rules in force. The apparatus comprises means for supplying the container of asbestos-containing waste to a crumbling assembly (in case of the big bags) where the homogenizing step and the addition of a bonding agent are carried out, means of controlling and proportioning the crumbled material, a compacting press which can also be supplied with the asbestos-containing waste in metal drums, and means for arranging the cakes from the press into containers of reinforced concrete and then for carrying out the sealing casting.
