6. SHS as a reliable and effective method for forming protective coatings of dangerous solid wastes SHS can be carried out at room temperature - it does not need a furnace. As a result.
SHS may be utilised for the creation, in-situ, of hard, protective coatings of dangerous, large volume, solid wastes, such as mining dumps.
The waste materials can be covered with a thin layer of an SHS mixture, which partially melts and solidifies following SHS initiation. The hard, protective coating safely restricts air-born or water-born pollution.
Especially dangerous and toxic (e.g. radioactive) solid wastes may also be consolidated and neutralised by SHS, prior to burial or encapsulation.
SHS is cheap, easily adaptable and can be used in the field without special equipment or specialised training. Ideal for isolated or difficult to reach areas.
12. Conclusion SHS may be utilised for the creation, in-situ, of hard, protective coatings of dangerous, large volume, solid wastes
SHS may be utilised for cutting large-scale metallic structures, such as boats, buildings etc.
Especially dangerous and toxic (e.g. radioactive) solid wastes may be consolidated and neutralised by SHS, prior to burial or encapsulation
SHS catalysts are very active and cheap for environmental uses
Easy recycling of many solid wastes to product
SHS-is low energy consumption technology of ceramic materials production
