Workshop on Synergies in Mercury Waste Management

The Ministry of the Environment Japan (MoEJ), organised the Workshop on Synergies in Mercury Waste Management in collaboration with the Secretariat of the Minamata Convention on Mercury and the International Environmental Technology Centre of the United Nations Environment Programme (UNEP IETC) on 30th and 31st May 2019 in Osaka, Japan.

In the workshop, the participants discussed the needs on capacity building for the environmentally sound management of mercury wastes for developing countries and a cooperation with international organizations. Result of this workshop will be shared at the Conference of the Parties to the Minamata Convention at its third session (COP 3) in November 2019 in Switzerland.




Title: Workshop on Synergies in Mercury Waste Management

Date: 30-31 May 2019

Venue: Osaka, Japan

Organizers: MoEJ, the Secretariat of the Minamata Convention and UNEP IETC

Participants: Around 50 people, including governmental officials, experts, etc., from Asia and the Pacific, Africa, Europe and Latin America regions.


The workshop had various presentations and discussions on the 3 topics as follows:

1) Identification of the needs for capacity-building, technical assistance and technology transfer on mercury waste management

The workshop discussed the needs and methods on capacity-building, technical assistance and technology transfer. For example, it was identified the importance of sharing best practices to implement the Minamata Convention on Mercury. They also discussed the importance to support capacity-building on individual items, such as remediation of contaminated site and collection of waste.

2) Synergies between the Minamata Convention on Mercury and other multilateral environmental agreements in relation to mercury waste

The workshop discussed necessary contents to be included in a next edition of the Basel Convention Technical Guidelines on the Environmentally Sound Management of Mercury Waste that Japan was a lead country to develop.

One of the important points was to organise training courses to use the guidelines, taking into account current situations on waste management among countries.

They also discussed the issue on open burning of waste as one of emission sources causing air pollutions and considered the necessity to establish law and regulations to be enforced by national and local governments to stop open burning of waste.

Furthermore, the workshop discussed to encourage collaborations among stakeholders and to increase awareness-raising on mercury waste management by using relevant targets and goals of the Sustainable Development Goals 2030 (SDGs).

3) Linkage between article 11 (mercury waste) and other articles of the convention, including products, emission and releases

The workshop discussed the role of producers and the necessity of collaborations between governments and industries, taking into account of coming measure to control mercury-added products.

They also discussed reduction of emission and releases of mercury to the environment and identified one possibility to reduce mercury emission and releases by collecting mercury.

They further discussed the necessity of analytical methodology to identify contaminated sites and capacity-building for artisanal and small-scale gold mining and contaminated sites. In order to prevent further contaminated sites, they considered the important role at management sides, such as support from governments and industries to miners.
