This 5-country project on “Mercury Waste Management” was implemented from 5 November 2008 until 30 June 2010. The project included four countries – Burkina Faso, Cambodia, Pakistan and Philippines - that were financed by the Government of Norway. The participation of Chile was made possible with funds from the Mercury Trust Fund. This project deals with the management of mercury and mercury-containing waste and will contribute to the UNEP priority area on harmful substances and hazardous waste under its Medium-Term Strategy with the ultimate goal of minimizing the impact of harmful substances and hazardous waste to the environment and human beings. The objectives of this project were to address mercury issues where mercury in any of its forms – metallic or ionic – enters the waste stream. All participating countries had developed initial mercury inventories, which were taken as a starting point. The inventories were further refined and the applicability of the Draft Basel Technical Guidelines on the Environmental Sound Management of Waste Consisting of Mercury, Containing or Contaminated with Mercury was tested.
