Title: Process and plant for treatment of household waste by physico-chemical and thermic means
Inventor: SAVORET JEAN-LOUIS
IPC: B09B3/00
Filed: 1993-02-05
Abstract: According to the invention, household waste dumped in bulk in a discard hopper (1) is subjected to plastic bag stripping (3) and then to removal of metal scrap (4). The waste is then subjected to two successive grinding processes (5, 6) and inserted into a mixer (7) simultaneously with the addition of mineral reagents (ACM) of the CaCO3 and CaO type; after impregnation, the powdered waste is again ground and then reblended (15) with a second addition of mineral reagents (ACM). The waste is then subjected to stabilization by heat treatment in a heated dual-envelope enclosure (17) provided with a series of heating, baking, vapour removal, cooling zones. The sand-type products are either recovered or densified (25) into balls. The final products (sand, balls) are inert, stable and are not harmful for the environnement. The process does away with dumping of waste, enhaces recyclable final products and protects the environnement.
