Lityum Geri Dönüşümü vs. Politika: Ölçeklenmeyi Engelleyen Nedir?

Lityum Kaynağı: Madencilik vs. Geri Dönüşüm (Hangisi Daha Hızlı Ölçeklenir?)

With the trend of electrification, lithium has quickly become an important global commodity, almost entirely driven by EV adoption.

Diğer pil kimyaları olan sodyum-iyon gibi seçenekler kitlesel üretim için değerlendiriliyor olsa da, lityum hâlâ pil kimyasallarının kralı konumunda; çünkü olağanüstü elektriksel özelliklere sahip.

Bu yüzden son birkaç yılda lityum talebi sürekli patladı ve 2020 ile 2025 arasında neredeyse dört katına çıktı.

Şu anda lityumun büyük bir kısmı, konsantre yataklardan, ya tuzlu su (brine) kaynaklarından ya da spodumen adı verilen mineral yataklarından üretiliyor.

Eski pillerin geri dönüştürülmesi muhtemel yeni bir lityum kaynağı olacak. Ancak bunun için uygun teknolojik altyapının geliştirilmesi, gerekli tesislerin inşa edilmesi ve sağlam bir yasal‑düzenleyici çerçeve oluşturulması gerekiyor.

How lithium recycling will impact lithium production in the future has recently been discussed in detail by researchers at the Australian Edith Cowan University and University of Western Australia, in a paper¹ published in the Journal of Environmental Management under the title “A comprehensive review on the recovery of lithium from lithium-ion batteries and spodumene”.

Brinlerden ve Spodumen’den Pil Kalitesinde Lityuma

In the immediate future, the largest increase in lithium production is expected to come from Australia and its rich resources of spodumene. In parallel, extraction from brines, mostly in Chile and Argentina, and partially in China, is also growing, but at a slower pace.

Piller yaşlandıkça, özellikle %70‑%80 şarj seviyesine düştüklerinde emekliye ayrılan EV pilleri, yer üstünde kolayca erişilebilen büyük bir lityum kaynağı haline geliyor.

2023 yılında küresel pil üretimi yaklaşık 2,5 TWh seviyesine ulaştı; 2023 eklenen kapasite, 2022’ye göre %25’in üzerinde artış gösterdi. Aynı dönemde lityum talebi ise yaklaşık %30 arttı.

In comparison, global recycling capacity surpassed 300 GWh per year in 2023, with over 80 % of this capacity located in China. In comparison, Europe and the United States each account for less than 2 % of global recycling capacity. So the current recycling capacity covers only 12% of the current battery production, which is also still more than doubling every 2-3 years.

EV Pil Atıkları: Ölçek, Riskler & Yangın Tehlikeleri

From 2021 to 2030, an estimated 12.85 million tons of EV lithium-ion batteries will retire globally, according to Greenpeace. For China, multiple industry forecasts point to ~3–3.5 million tons by 2030, underscoring the urgency of large-scale collection and recycling.

This could cause significant pollution and environmental risks, as lithium batteries contain a complex mix of chemicals, including heavy metals. So recycling is not only a question of reducing the impact of lithium production, but also avoiding other types of pollution as well.

Unrecycled batteries can also cause landfill fires, which, combined with landfills’ methane production, can have catastrophic consequences.

Surface and underground fires can cause the production of toxic gases like dioxins, furans, volatile organic compounds (VOCs), polychlorinated biphenyls, organochlorine pesticides (Nair et al., 2019/01), polycyclic aromatic hydrocarbons (PAHs), carbon monoxide, sulfur dioxide, and hydrogen sulphide (IEAa).

Pil Geri Dönüşümü: Hidromet vs. Piromet vs. Doğrudan Geri Kazanım

There are currently three main methods for recycling spent lithium batteries: pyrometallurgy, hydrometallurgy, and direct recovery.

Kaynak: ResearchGate

Overall, these methods are only a little less energy-intensive than the production of lithium from raw natural resources, but greatly reduce the rest of the environmental impact.

For example, recycling lithium batteries reduces CO2 emissions, greatly reduces SO2 (sulphur) emissions, and can reduce water consumption by more than half in the case of pyrometallurgical methods.

Kaynak: Journal Of Environmental Management

Both pyrometallurgy and hydrometallurgy use so-called “black mass”, or crushed battery containing a complex mix of metals and chemicals.

Of these methods, pyrometallurgy is the most polluting in terms of unwanted toxic gases. In contrast, hydrometallurgy is less toxic, but requires more water resources (but still a lot less than raw lithium ores).

Both types of recycling take several steps, each producing its own type of pollution that needs to be dealt with.

Lityum Geri Dönüşümünü Geri Tutan Düzenleyici Boşluklar

Currently, most batteries are not recycled, in part due to a lack of capacity, in part due to insufficient regulations.

A stricter framework mandating the collection and proper recycling of the existing batteries is required. This will not only boost the collection of potentially harmful waste but also provide the industry with a predictable volume of materials, helping size the recycling infrastructure correctly.

The scientists looked at the cost breakdown of recycling, and discovered that collection, transport, battery disassembly, and pretreatment (crushing or melting) represent a large portion of total costs.

Kaynak: Journal Of Environmental Management

As a result, an optimization of these processes through adequate policy, centralized waste collection, and optimization of recycling sites could greatly increase the profitability of lithium battery recycling. And while better technology can reduce cost for the other steps, these early costs are more of a policy issue.

Due to its lower energy consumption and pollution, hydrometallurgy should be encouraged by policymakers, and sites chosen should be ideally both energy and water-rich to not strain local resources.

The research also discovered that the type of battery recycled greatly affected the profitability of recycling.

“The revenue generated from recycling LCO (Lithium Cobalt Oxide) batteries was 7 times greater than that of LFP (Lithium Ferrum Phosphate) batteries and 10 times greater than that of LMO (Lithium Manganese Oxide) batteries.”

As LFP batteries are becoming more common, in a bid to reduce costs and dependency on cobalt supply from Congo, this should be factored into policies regarding battery recycling.

Sonuç: Politika Geri Dönüşüm Hızını Belirleyecek

Lithium recycling technology is now becoming more mature, with hydrometallurgy coming out as a clear winner against pyrometallurgy when taking into account air pollution (toxic gases) and energy consumption.

However, recyclers are facing a few issues that they are not going to be able to solve by themselves, and instead require a quick move by legislators.

The first step is to organize a much more efficient collection of used batteries, which might require a strong obligation of battery and EV manufacturers to keep track and prove the recovery of the products they previously sold to the public.

In that respect, the plans by the EU stipulating that by 2031 all batteries must contain 6% recycled lithium material and up to 12% by 2036 are probably not enough.

The second step will be to properly encourage the adoption of hydrometallurgy in recycling facilities and offer the proper incentives in terms of environmental controls.

Lastly, building recycling facilities is a very capital-intensive activity, and the public sector could provide grants, subsidies, and low-interest loans to speed up construction. As global recycling capacity is already lagging much behind current battery production volumes, which are also exploding, quick actions are required.

Western legislators in particular should pay attention to the fact that their countries are already severely lagging behind China in recycling, which could, in the long term, lock inside China a major new source of battery metals, as well as many new green energy jobs.

Illustrative of this trend, the battery giant CATL (Contemporary Amperex Technology Co., Limited – 3750.HK) is already envisioning that 50% of its new batteries will use no mined minerals within 20 years, and only because it expects demand to grow quicker than the supply of older batteries.

CATL is also building its own battery collection network, Brunp Recycling, with already 240+ collection depots, a 99.6% recovery rate of nickel, cobalt, and manganese, and 10,000+ employees.

Historically focused on lithium mining, Albemarle is also making inroads into recycling. Many of the steps used in recycling are identical or similar to the ones used in refining the raw ore, giving a valuable expertise to Albemarle.

“For us in the long term, (black mass) will probably be another resource.

Typically, the black mass that comes out of recycling is very similar to the concentrate produced at our conversion assets. So I think it’s an opportunity for us.”

Meredith Bandy – Vice president of investor relations and sustainability at Albemarle

Albemarle aims to build a lithium processing facility in the US Southeast later this decade to process and recycle lithium.

This will also be an important move for Albemarle to not be left out of a new source of lithium that could compete with its current production from brine and spodumene.

With strong liquidity and a debt held at a low fixed rate, Albemarle is also well positioned to endure the context of low lithium prices of the last few years, increasing its market share against smaller, less capitalized competitors.
