ASGM Projects: Indonesia

Phase 2 - 2015

As a follow-up to the successful work in Phase 1 (see below), UNEP is working with Yayasan Tambuhak Sinta to build capacity for mercury-free ASGM methods and raise awareness on the risks of mercury use at the national, regional, and local level.

The project is developing a mercury-free ASGM demonstration plant and training center in East Java, as well as convening workshops for national and regional government officials to advance national action planning.

The project is funded by the Government of Norway.

Phase 1 - 2012-2013

The project, led by Blacksmith Institute and Yayasan Tambuhak Sinta in collaboration with UNEP and funded by the US Environmental Protection Agency, gathered data on mercury releases from the ASGM sector and brought together representatives from local and national Government, local mining offices, research institutes and mining NGOs to develop a national strategic plan for the sector considering broader sustainable development objectives.


  • Ten sluices, ninety retorts and fifty water-box condensers were distributed to miners who had been trained in their use.
  • In parallel with this technical training, a number of events were held to raise the awareness of miners and processors, health professionals, schoolteachers and NGO leaders of the dangers of mercury use.
  • Information materials were developed with local community leaders so that appropriate messages about mercury can be delivered to those at greatest risk of exposure.


  • As a result of the project mercury releases to the environment were reduced by an estimated 3,000 kg in a single year by training small-scale gold miners in Indonesia to use improved processing techniques.
  • The work to develop the National Strategic Plan to reduce mercury use from ASGM was initiated. The plan was finalized in 2014.
