Indonesian authorities are considering two companies’ requests to dispose mining waste into the ocean, a senior government official said on Sunday, at a time of heightened sensitivity about the environmental impact of mining. The requests come as mining waste management is increasingly scrutinized after a nickel plant in neighboring Papua New Guinea spilled red mud into the sea last year due to an operational failure.
Indonesia was a major nickel ore exporter until last year, before the government stopped exports in January to support the development of domestic smelters. The government is keen to produce stainless steel and battery-grade chemicals from nickel laterite, and eventually manufacture batteries and electric vehicles. Environmentalists, however, are concerned such developments will damage the local ecosystem.
Harita Group is building a high-pressure acid leaching plant on Obi Island to extract battery-grade chemicals from nickel ore, and China’s Tsingshan Group, GEM Co Ltd and partners are doing likewise in Morowali on Sulawesi Island. Reuters could not reach Tsingshan or GEM for comment on Sunday. Calls to Harita went unanswered. Burhanuddin said provincial governors have issued permits, dependent on the national government approving the governors’ requests to revise their spatial planning jurisdictions to include deep-sea pipes for mining waste, or tailings.
