Description:
Several stabilization technologies exist: chemical transformation into a more stable, less mobile chemical compound; micro-encapsulation, the embedding of particles in an impermeable matrix such as cement; and macro-encapsulation, the covering of waste material with an impermeable material, for example polyethylene. The fact that stabilized mercury is non-toxic significantly helps the search for suitable storage sites. Unlike liquid mercury, the stabilized form is suitable for storage in landfills and underground. Mercury storage and disposal is a growing problem. The global trend towards phasing out products which contain mercury and processes which use it will soon generate an excess of mercury if supplies remain at their current level. Environmentally sound management of mercury waste will be a critical issue for most countries. There are some good examples. But in the Latin American and Caribbean region, mercury supply may exceed demand by 2013. In 2012, UNEP helped Argentin ...
