Waste to Energy

Magaldi is specialized in dry bottom ash handling systems for waste incinerators with no contamination of the environment. This innovative process allows to eliminate the usage of water for quenching the bottom ash and it is relevant for the quality of the metals in the bottom ash.
Therefore, the dry bottom ash discharge system reduces the overall amount of the bottom ash by weight. In addition, it increases the yields of the downstream metals recovery system, minimizing metals land filling and providing high-quality raw materials.
Since the incineration process cleans and separates metals from organic components, a dry extraction approach is the key factor to allow a more effective metal separation from inert matter. In fact, avoiding the reaction of bottom ash with water provides the key to recovering metals in their highest quality, as well as to very fine particle size.
