On land options include the dry stacking of tailings, using tailings as backfill in mines and building conventional tailings dams. Due to rainfall, the potential for dry stacking is difficult and costly, but by building a conventional tailing dam with very little hard-rock available to secure its walls, there is always a risk of collapse.

Indonesia has a chequered environmental track record in mining so EV companies could be cautious about directly investing given environmentally-conscious consumers, experts say.

"There are alternative options like dry-stack tailing, a method which absorbs all the water content in the tailing, then use the dry material for mine pit reclamation," he said. Dry-stacking reduces the environmental threat towards marine biodiversity and allows metal recovery and re-extraction, while DSTD excludes these possibilities.
