Scrapping the waste export levy could threaten Australia’s emerging lithium battery recycling industry

As electrical automobile (EV) demand accelerates, so does the necessity for lithium batteries. However these batteries comprise worthwhile important minerals, in addition to poisonous supplies, in order that they shouldn’t be handled as widespread waste.

Not like China and a few European international locations, Australia lacks a devoted lithium battery recycling facility. Just 10% of Australia’s lithium battery waste was “recycled” in 2021. This implies the batteries have been collected and shredded regionally earlier than being despatched abroad for recycling.

Delivery giant volumes of spent batteries abroad is advanced and dangerous. Lithium batteries have been recognized to begin fires. A cargo ship laden with lithium batteries caught fire off the coast of Alaska in December 2023. The fireplace burned for days.

Equally, a fireplace broke out on a cargo ship carrying luxury vehicles (including EVs) close to Portugal’s Azores Islands in February 2022. The danger of fireside is even higher for spent EV batteries as a result of they’re extra prone to be broken or unsafe.

Efforts to recycle batteries onshore have now been jeopardized by the choice—introduced final week forward of this week’s federal funds—to scrap plans for a waste export levy. The proposed A$4 per ton levy on waste exports would have come into impact on July 1.

Scrapping the levy will pave the best way for much more waste to be exported reasonably than recycled right here. We consider there ought to be exceptions for spent lithium batteries—for a number of causes. These embrace security considerations round delivery and the lack of important minerals.

By recycling onshore, we are able to retain these assets, construct new industries and develop a round economic system. We must also put together for the likelihood that different international locations will at some stage refuse to just accept our waste. Then we shall be pressured to stockpile these batteries, at nice danger.

Spent EV batteries are accumulating quickly

EV gross sales are rising exponentially. Globally, one in five new vehicles are electrical. More than half of all vehicles bought by 2040 will possible be EVs.

Beneath every smooth exterior is a hefty lithium battery with a mean lifespan of simply 5 to eight years.

In keeping with the Worldwide Vitality Company, EVs generated about 500,000 tons of battery waste in 2019 alone. This waste is forecast to succeed in 8 million tons by 2040.

A 2016 report for the federal authorities forecasts not less than 20% annual growth in Australian lithium battery waste to 136,000 tons a year by 2036.

CSIRO explored the potential for lithium battery recycling and reuse in 2021. However little has occurred since.

In the meantime, the mountain of waste continues to develop. It’s estimated 360,000 tons of EV batteries shall be spent by 2040 and 1.6 million tons by 2050.

Battery recycling is a should, not a alternative

Disposal of lithium batteries may cause fires and explosions in waste administration amenities and landfills. If a battery is punctured, or short-circuits, the residual electrical energy can spark fires or explode. The batteries may also leak metals equivalent to cobalt, nickel or manganese, threatening ecosystems and human health.

The battery fluid is dangerous to people as it’s linked to numerous well being results together with heart attacks, asthma, cancer, eye damage, reproductive toxicity, skin sensitisation, damage to bones and kidneys and different signs.

Lithium battery wastes are overground mines

Slightly than being seen as a legal responsibility, the rising pile of spent lithium batteries may symbolize an financial alternative for Australia. The battery pack in a BMW i3 electrical automobile, for instance, accommodates 6kg of lithium, 35kg of graphite, 2kg of cobalt, 12kg of nickel and 12kg of manganese. These worthwhile assets shall be wasted if the batteries are exported or despatched to landfill.

If the uncooked supplies have been as a substitute recovered and processed onshore, this might translate right into a burgeoning business price A$3.1 billionutilizing Australia’s present experience in mining and useful resource restoration.

It is time to get severe about battery recycling

The federal authorities missed a chance to incorporate infrastructure for battery recycling in its A$250 million Recycling Modernisation Fund. These funds have been restricted to waste glass, plastic, tires, paper and cardboard.

This delays the institution of onshore capability for battery recycling and makes us reliant on exporting waste batteries abroad.

To spice up recycling, we should develop clear rules and tips aligned with international requirements, together with stringent restrictions on landfill.

As well as, incentives equivalent to tax credit and rebates for battery recycling packages will encourage funding on this space and drive progress. Such measures in Europe make the legislated goal for lithium restoration from waste batteries (63% by 2027) doable, chopping reliance on imports of uncooked supplies.

We urgently have to develop a complete waste administration technique devoted to the accountable assortment and recycling of waste batteries. Such a method is essential to safeguard each the surroundings and communities from the potential hazards related to improper disposal, selling useful resource conservation and making a round economic system for these important power storage gadgets.
