Electric vehicle sales are racing ahead, but is there a plan for the waste they create? | CBC News

There is a new enterprise happening in a big, nondescript warehouse in Kingston, Ont.: Lithium-ion battery recycling. And it could possibly be an essential element of Canada’s net-zero future.

The ability, owned by Canadian startup Li-Cycle, homes stacks of depleted lithium-ion batteries that not way back would have been destined for a landfill. The corporate is giving them new life — recycling the batteries that energy most electrical automobiles, telephones and laptops.

“It is type of like city mining,” stated Li-Cycle CEO Ajay Kochar. “Mainly, we will be sure that no matter we get out of the bottom and put into batteries, we get as a lot of it again.”

Auto analysis agency J.D. Energy estimates electrical car batteries have a lifespan of ten to twenty years — so electrical automobiles have now been round lengthy sufficient in Canada that some batteries will have to be changed close to the top of the last decade.

Discovering methods to recycle their expensive, poisonous batteries may tackle the environmental questions that come up from constructing electrical automobiles within the first place.

Retrieving ‘black mass’

Li-Cycle shreds the spent batteries and separates the supplies by a water-based method often known as hydrometallurgical processing.

It sifts out metals and plastics for recycling, leaving the primary byproduct — a dirt-like substance often known as black mass. Black mass is made up of lithium, cobalt and nickel; essential minerals which can be the constructing blocks of EV batteries.

Beginning in 2023, Li-Cycle will ship the black mass to a brand new facility it’s constructing in Rochester, N.Y., the place it will probably separate the black mass into beneficial battery-grade supplies for use to make new EV batteries. Li-Cycle says the plant would be the first supply of recycled battery-grade lithium carbonate manufacturing in North America.

Kochar stated his firm can get better 95 per cent of these essential minerals wanted to make new EV batteries, and the method can occur repeatedly.

“There is no restrict on the variety of occasions the identical lithium, nickel and cobalt might be recycled,” he stated.

The function essential minerals play

The function essential minerals play in making EV batteries has come underneath a microscope lately. They’re mined in only a few international locations and demand has soared amid a good provide, inflicting costs to spike.

Canada and the U.S. have every plowed forward with plans this yr to safe home provide chains of essential minerals to enhance the extraction in addition to recycling of fabric like lithium.

In early December, Ottawa unveiled a technique that may enable for sooner approvals on essential minerals tasks.

On the time, Pure Assets Minister Jonathan Wilkinson stated that with out essential minerals, “there is no such thing as a inexperienced vitality transition.”

In keeping with a 2020 report by the Worldwide Council on Clear Transportation, recycling outdated EV batteries may cut back the necessity for brand spanking new mining by 20 per cent by 2040.

“We do want the fabric within the first place, so that should occur as cleanly as doable,” stated Kochar. “However as soon as we’ve the [critical minerals], we’ve to maintain it in a round loop and never have to return and have extra impression by way of mining.”

Battery waste a worldwide problem

Li-Cycle is not the one battery recycler within the nation. Different Canadian gamers embody Lithion Recycling and Retriev Applied sciences, they usually’re all ramping up as Canada strikes to mandate EV gross sales.

The federal authorities is proposing rules that may require 20 per cent of all passenger automobiles bought within the nation to be electrical beginning in 2026, and transferring as much as 60 per cent of all gross sales by 2030.

Josipa Petrunic, president and CEO of the Canadian City Transit Analysis and Innovation Consortium, says waste from depleted lithium-ion batteries is an issue proper now, and already piling up globally. 

“The truth is that battery waste is just about my technology’s nuclear waste downside,” she stated. “So we will must determine it out, whether or not we prefer it or not.”

Incentives should hook up with recycling applications

Whereas Canada hasn’t pledged federal funding for recycling EV batteries, the U.S. is spending tons of of tens of millions of {dollars} on recycling tasks. The U.S. Senate additionally simply handed a invoice to extend EV battery recycling, which may quickly be signed into legislation.

Petrunic says Ottawa must enact insurance policies that join incentives for EV purchases and manufacturing to recycling.

“The federal government can compensate for recycling actually quick by tying all of that cash, billions of {dollars}, to recycling plans, in order that cities and customers cannot purchase vehicles or buses that do not have a recycling plan connected to them.”

Paul Rapoport was an early EV adopter, and purchased his Tesla Mannequin S in 2014 as a technique to cut back car emissions.

Again then, there was little details about EV battery recycling. He thinks recycling choices will drive extra customers to EVs as a result of they will really feel higher about the place the batteries will find yourself.

“It is crucial to know that these batteries will not be going to finish up in a landfill perpetually and ever.”
