In 2012, the International Maritime Organization (IMO), adopted resolution MEPC 219(63). This establishes the hazard classification criteria for solid substances, transported as bulk cargo, to be considered as “harmful to the marine environment” (HME) for the purposes of restricting the disposal of solid bulk cargo residues under the amended Annex V of the MARPOL Convention.
Copper concentrates are solid mining products transported in bulk. The need for classifications of these materials, for the human health and environmental hazard categories set out in the HME criteria, was assessed following the UN-GHS 4th revision and the ICMM guidance (2013)1 on HME assessment of ores and concentrates.
The results are summarised in this report.
