Battery recycling

Last updated

Battery recycling is a recycling activity that aims to reduce the number of batteries being disposed as municipal solid waste. Batteries contain a number of heavy metals and toxic chemicals and disposing of them by the same process as regular household waste has raised concerns over soil contamination and water pollution. [1] While reducing the amount of pollutants being released through disposal through the uses of landfill and incineration, battery recycling can facilitate the release of harmful materials from batteries to both the environment and the workers recycling batteries.

Battery recycling by type

Most types of batteries can be recycled. However, some batteries are recycled more readily than others, such as lead–acid automotive batteries (nearly 90% are recycled) and button cells (because of the value and toxicity of their chemicals). [4] Rechargeable nickel–cadmium (NiCd), nickel–metal hydride battery (NiMH), lithium-ion (Li-ion) and nickel–zinc (NiZn), can also be recycled. Disposable alkaline batteries make up the vast majority of consumer battery use, but there is currently no cost-neutral recycling option. Consumer disposal guidelines vary by region. [5] An evaluation of consumer alkaline battery recycling in Europe showed environmental benefit but at significant expense over disposal. [6] Zinc–carbon and Zinc–air batteries are recycled in the same process. [6] : 20–24  E.U. consumers recycled almost half of portable batteries bought in 2017. [7]

Lead–acid batteries

Lead-acid batteries include but are not limited to: car batteries, golf cart batteries, UPS batteries, industrial fork-lift batteries, motorcycle batteries, and commercial batteries. These can be regular lead–acid, sealed lead–acid, gel type, or absorbent glass mat batteries. These are recycled by grinding them, neutralizing the acid, and separating the polymers from the lead. [8] The recovered materials are used in a variety of applications, including new batteries.

The lead in a lead–acid battery can be recycled. Elemental lead is toxic and should therefore be kept out of the waste stream.

The casing of a lead–acid battery is often made of either polypropylene or ABS, which can also be recycled, although there are significant limitations on recycling plastics. [9]

Many cities offer battery recycling services for lead–acid batteries. In some jurisdictions, including U.S. states and Canadian provinces, a refundable deposit is paid on batteries. This encourages recycling of old batteries instead of abandonment or disposal with household waste. Businesses that sell new car batteries may also collect used batteries (or be required to do so by law) for recycling. [10]

A 2019 study commissioned by battery-industry promotional group, the Battery Council, calculated battery lead recycling rates in the United States in the period 2014–2018, taking into account battery scrap lead import/export data from the Department of Commerce. The report says that, after accounting for net scrap battery lead exports from the United States, 99.0% of the remaining lead from lead-acid batteries in the United States is reclaimed. The Battery Council figures indicate that around 15.5 billion pounds of battery lead was consumed in the USA in that period, with a net amount of approximately 2 billion pounds battery scrap lead being exported. Of the 13.6 billion pounds remaining after exports, 13.5 billion pounds were recycled. [11]

The U.S. Environmental Protection Agency (EPA), has reported lesser and varying levels of lead-acid battery recycling in the United States in earlier years, under various administrations, Republican and Democrat. The EPA reported in 1987 that varying economics and regulatory requirements have contributed to rates of 97 percent in 1965, above 83 percent in 1980, 61 percent in 1983, and around 70 percent in 1985. [12]

According to a 1992 EPA Superfund report, lead batteries account for about 80% of the lead used in the United States, of which about 60% is reclaimed during times of low lead prices, but more in times of high lead prices; it reported that 50% of the nation's lead needs are filled from recycled lead. [2]

Silver-oxide batteries

Used most frequently in watches, toys, and some medical devices, silver-oxide batteries contain a small amount of mercury. Most jurisdictions regulate their handling and disposal to reduce the discharge of mercury into the environment. [13] Silver oxide batteries can be recycled to recover the mercury through the use of both Hydrometallurgical methods and pyrometallurgical methods. [14]

More recent silver oxide batteries no longer contain mercury and the process of recycling them does not give cause for concern for releasing mercury into the environment. [14]

Lithium-ion batteries

Lithium-ion batteries contain lithium and high-grade copper and aluminium. Depending on the active material, they may also contain cobalt and nickel. To prevent a future shortage of cobalt, nickel, and lithium and to enable a sustainable life cycle of these technologies, recycling processes for lithium batteries are needed. [15] These processes have to regain not only cobalt, nickel, copper, and aluminium from spent battery cells, but also a significant share of lithium. Other potentially valuable and recoverable materials are graphite and manganese. Recycling processes today recover approximately 25% to 96% of the materials of a lithium-ion battery cell. [16] [17] In order to achieve this goal, several steps are combined into complex process chains, while ensuring safety. [18] [19]

These steps are: [18]

One or more of these metal recovery processes are used to recover critical metals from battery waste. In hydrometallurgical methods, metals are first extracted in aqueous solution, typically using acids (such as sulfuric acid) and hydrogen peroxide as a reducing agent. This is followed by selective precipitation of the metals as salts. Hydrometallurgical processes have several advantages, such as low energy consumption, low cost and little hazardous gas emission. [7] However, the use of dangerous acids during extraction poses safety concerns. Additionally, the method requires extensive and complicated processing to selectively precipitate each metal salt. [21]

Pyrometallurgy involves the smelting of battery materials, followed by hydrometallurgical extraction to obtain metal salts from the slag. Pyrometallurgy has advantages such as flexibility in battery feedstock and simpler pretreatment methods. [5] However, extremely high temperatures are required for smelting, giving pyrometallurgy a relatively high carbon footprint. This method also requires extensive processing of the slag, and is unable to recover lithium from the slag. [21]

Direct recycling is an emerging battery recycling method that focuses on directly regenerating cathode materials without damaging the crystal structure. [22] This is distinct from existing hydro- and pyrometallurgical methods, which break down the cathode into precursors and require subsequent processing to regenerate cathode materials. [21] [23] Maintaining the cathode structure represents an important increase in efficiency, since it produces a higher-value product than other recycling methods. [23] In order to perform direct recycling, the cathode "black mass" (containing critical metals such as Li, Co, Mn, and Ni) must be separated from other battery components. Traditional separation methods, primarily battery shredding, are insufficient, as they introduce impurities into the cathode. [23] Alternative separation methods include the use of solvents to recover the black mass. Many of the organic solvents investigated for this process are toxic and pose hazards to both humans and the environment. [23] [24] Identifying safer solvents which can effectively separate the black mass is a topic of current research. [24] Once the cathode black mass is obtained, the material undergoes relithiation to reintroduce lithium which is "lost" during battery use and restore the cathode to its original capacity. This relithiation process can be carried out via several different methods, including solid state, electrochemical, or solution-based relithiation. [23] While direct recycling is not yet commercialized, research indicates that it can restore cathode materials to their original electrochemical capacity and performance. [24]

Specific dangers associated with lithium-ion battery recycling processes include electrical, chemical, and thermal dangers, and their potential interactions. [18] A complicating factor is the water sensitivity: lithium hexafluorophosphate, a possible electrolyte material, reacts with water to form hydrofluoric acid; cells are often immersed in a solvent to prevent this. Once removed, the jelly rolls are separated and the materials removed by ultrasonic agitation, leaving the electrodes ready for melting and recycling.

Pouch cells are easier to recycle to salvage copper despite significant safety issues.

Extraction of lithium from old batteries is five times more expensive than mined lithium. [25] However, lithium extraction from Li-ion batteries has been demonstrated in small setups by various entities [16] [26] [17] as well as in production scale by battery material recycling companies like Electra Battery Materials [27] and Redwood Materials, Inc. [28]

A critical part of recycling economics is the value of the recovered cobalt. Manufacturers working to remove cobalt from their products might produce the unintended consequence of reducing recycling. [29] A novel approach is to maintain the cathode's crystalline structure, eliminating the significant energy expense of recreating it. [29] Another approach is to use ultrasound for separating the individual cathode components. [30]

While cathode materials are the focus of most recycling efforts due to their high economic value, recycling additional battery components could improve the overall sustainability of lithium-ion batteries. Studies have found that components such as the battery casing, current collectors, electrolyte, and separators have potential to be recycled given further research into processing methods. [23] In addition, recycling anode materials (primarily graphite) could significantly increase the recovery of lithium from spent batteries, since much of the lithium "lost" during battery use ends up in the anode. [23]

Energy saving and effective recycling solutions for lithium-ion batteries can reduce the carbon footprint of the production of lithium-ion batteries significantly. [17] [31] As of 2022, several facilities are operating and under construction, [32] including Fredrikstad in Norway [33] and a black mass facility in Magdeburg, Germany in 2023. [34]

In early 2022, research published in Joule showed that recycling existing lithium-ion batteries by focusing on a method that refurbishes the cathode showed that this technique perform just as well as those with a cathode made from original materials. The study showed that the batteries using the recycled cathode charged faster and lasted longer than new batteries. [35]

By 2023, several companies had moved beyond research and had set up process lines to recycle commercial quantities of Li-ion batteries. In its Nevada pilot plant, the Redwood Materials process had recovered more than 95% of important metals (including lithium, cobalt, nickel and copper) from 230,000 kg (500,000 lb) of old NiMH and Li-Ion packs.

Battery recycling by location

Battery recycling is an international industry, with many nations exporting their used or spent lead-acid batteries to other nations for recycling. Consequently, it can be difficult to get accurate analyses of individual nations' exact rate of domestic recycling. [37] [38]

Further, in many countries, lead-acid battery recycling (chiefly from automobiles and motorcycles) is commonly done informally by individuals or informal enterprises, with little or no formal record-keeping, nor effective regulatory oversight. [37]

Spent lead–acid batteries are generally designated as "hazardous waste" and subject to relevant safety, storage, handling and transport regulations, though those vary from country to country. A multilateral international agreement, the Basel Convention, officially governs all transboundary movements of hazardous waste for recovery or disposal, among the 172 signatory countries. (The U.S. is not a party, but has alternate arrangements with the Organisation for Economic Co-operation and Development (OECD), and with Canada and with Mexico (where it ships many lead-acid batteries for recycling [37] ).

European Union

In 2006, the European Union passed the Battery Directive, one of the aims of which is a higher rate of battery recycling. The EU directive states that at least 25% of all the EU's used batteries must be collected by 2012, and rising to no less than 45% by 2016, of which at least 50% must be recycled. [39] In 2020, 47% of batteries in the EU were collected for recycling. [42]

Channel Islands

In early 2009, Guernsey took the initiative by setting up the Longue Hougue recycling facility, which, among other functions, offers a drop-off point for used batteries so they can be recycled off-island. The resulting publicity meant that a lot of people complied with the request to dispose of batteries responsibly.

United Kingdom

From April 2005 to March 2008, the UK non-governmental body WRAP conducted trials of collection methods for battery recycling around the UK. [43] The methods tested were: Kerbside, retail drop-off, community drop-off, postal, and hospital and fire station trials. The kerbside trials collected the most battery mass, and were the most well-received and understood by the public. The community drop-off containers that were spread around local community areas were also relatively successful in terms of mass of batteries collected. The lowest performing were the hospital and fire service trials (although these served their purpose very well for specialized battery types like hearing aid and smoke alarm batteries). Retail drop off trials were by volume the second most effective method but one of the least well received and used by the public. Both the kerbside and postal trials received the highest awareness and community support. [44]

Household batteries can be recycled in the UK at council recycling sites as well as at some shops and shopping centers, e.g. Currys, and The Link. [45]

A scheme started in 2008 by Sainsbury's allowed household batteries to be posted free of charge in envelopes available at their shops. This scheme was cancelled at the request of the Royal Mail because of hazardous industrial battery waste being sent as well as household batteries. [46]

From 1 February 2010, batteries can be recycled anywhere the "Be Positive" sign appears. Shops and online retailers that sell more than 32 kilograms of batteries a year must offer facilities to recycle batteries. This is equivalent to one pack of four AA batteries a day. Shops that sell this amount must by law provide recycling facilities as of 1 February 2010. [47]

In Great Britain an increasing number of shops (Argos, Homebase, B&Q, Tesco, and Sainsbury's) are providing battery return boxes and cylinders for their customers. [48] [49]

North America

The rechargeable battery industry has formed the Rechargeable Battery Recycling Corporation (RBRC), which operates a battery recycling program called Call2Recycle throughout the United States and Canada. [50] [51] RBRC provides businesses with prepaid shipping containers for rechargeable batteries of all types while consumers can drop off batteries at numerous participating collection centers. It claims that no component of any recycled battery eventually reaches a landfill. Other programs, such as the Big Green Box program, offer a recycling option for all chemistries, including primary batteries such as alkaline and primary lithium.

A study estimated battery recycling rates in Canada based on RBRC data. [52] In 2002, it wrote, the collection rate was 3.2%. This implies that 3.2% of rechargeable batteries were recycled, and the rest were thrown in the trash. By 2005, it concluded, the collection rate had risen to 5.6%.

In 2009, Kelleher Environmental updated the study. The update estimates the following. "Collection rate values for the 5 [and] 15-year hoarding assumptions respectively are: 8% to 9% for NiCd batteries; 7% to 8% for NiMH batteries; and 45% to 72% for lithium ion and lithium polymer batteries combined. Collection rates through the [RBRC] program for all end of life small sealed lead acid (SLA) consumer batteries were estimated at 10% for 5-year and 15-year hoarding assumptions. [...] It should also be stressed that these figures do not take collection of secondary consumer batteries through other sources into account, and actual collection rates are likely higher than these values." [53]

A November 2011 The New York Times article reported that batteries collected in the United States are increasingly being transported to Mexico for recycling as a result of a widening gap between the strictness of environmental and labor regulations between the two countries. [37] [54]

In 2015, Energizer announced availability of disposable AAA and AA alkaline batteries made with 3.8% to 4% (by weight) of recycled batteries, branded as EcoAdvanced. [55] [56]

Japan

Japan does not have a single national battery recycling law, so the advice given is to follow local and regional statutes and codes in disposing batteries. The Battery Association of Japan (BAJ) recommends that alkaline, zinc-carbon, and lithium primary batteries can be disposed of as normal household waste. [57] The BAJ's stance on button cell and secondary batteries is toward recycling and increasing national standardisation of procedures for dealing with these types of batteries. [58]

In April 2004, the Japan Portable Rechargeable Battery Recycling Center (JBRC) was created to handle and promote battery recycling throughout Japan. They provide battery recycling containers to shops and other collection points. [59]

India

India is one of the world's chief consumers of lead–acid batteries, according to the India Lead Zinc Development Association (ILZDA). [60] India, with its recent rapid rise in average wealth, has seen a marked increase in motor vehicles, and a corresponding increase in lead-acid battery recycling.

India lacks a formal planned recycling industry. The industry is not respected, and lacks designated zones for recycling. However, in a nation with a vast population of people still in poverty, most lead-acid battery recycling is by individuals and small informal enterprises, often taking no safety or environmental precautions. [60] [37] [61]

ILZDA has demanded multiple changes to India's industry and its regulation, including the registration of all battery dealers, and the collection of their returns, and recognition of the best-registered recyclers, while enforcing punishments for violators of government regulations. [60]

Two of India's largest lead companies—lead manufacturer/exporter Gravita India and lead battery manufacturer Amara Raja—partnered to annually recycle 8,000 tonnes of lead scrap from Amara Raja's facilities, and return it to them for re-use (Gravita said it can recycle and process up to 50,000 tonnes of lead and aluminium yearly). The companies said the joint program is to advance environment protection and sustainability. [62]

Health and Environmental Concerns

Despite the positive outlooks on battery recycling, negative effects also have been shown to impact developing nations that recycle batteries, especially those with lead and lithium.

Lead is a highly toxic substance, and processing it can result in pollution and contamination of people, resulting in long-term health problems and even disability. [63] [37] According to one ranking, lead-acid battery recycling is, by far, the most deadly industrial process, globally, in terms of disability-adjusted life years lost—costing between 2,000,000 and 4,800,000 estimated lost years of individual human life. [64]

Since 2015, developing nations like Vietnam have increased their battery processing capacity as global demand for batteries has grown. The process for recycling batteries often leads to toxic metals being introduced into the environment. In many of these nations, there are little protections available for workers working with the batteries. [3] In nations like Indonesia, it was reported that over a span of four years, battery recycler's blood lead levels almost doubled. [65] Lead exposure to workers can also be transmitted to family members away from work, ultimately leading to lead poisoning. [66]

More studies continue to be conducted to gather an understanding of environmental impacts. Studies show that most lithium-ion batteries contain Per- and polyfluoroalkyl substances (PFAS). PFAS accumulates in humans and wildlife, often leading to immune and thyroid disfunctions, liver diseases, and other issues relating to homeostasis inside of the body. [67] Lead contamination of neighborhoods has resulted from the process of recycling lead batteries. In 1992, the EPA reported 29 lead-recycling sites were on the EPA's Superfund clean-up list, 22 of them on their "National Priority List." [2]

A nickel–metal hydride battery is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium. NiMH batteries can have two to three times the capacity of NiCd batteries of the same size, with significantly higher energy density, although only about half that of lithium-ion batteries.

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991: over the following 30 years, their volumetric energy density increased threefold while their cost dropped tenfold.

<span class="mw-page-title-main">Rechargeable battery</span> Type of electrical battery

A rechargeable battery, storage battery, or secondary cell, is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead–acid, zinc–air, nickel–cadmium (NiCd), nickel–metal hydride (NiMH), lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), and lithium-ion polymer.

<span class="mw-page-title-main">Alkaline battery</span> Type of electrical cell

An alkaline battery is a type of primary battery where the electrolyte has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide.

A primary battery or primary cell is a battery that is designed to be used once and discarded, and it is not rechargeable unlike a secondary cell. In general, the electrochemical reaction occurring in the cell is not reversible, rendering the cell unrechargeable. As a primary cell is used, chemical reactions in the battery use up the chemicals that generate the power; when they are gone, the battery stops producing electricity. In contrast, in a secondary cell, the reaction can be reversed by running a current into the cell with a battery charger to recharge it, regenerating the chemical reactants. Primary cells are made in a range of standard sizes to power small household appliances such as flashlights and portable radios.

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants. Most industrial processes, such as petroleum refineries, chemical and petrochemical plants have their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of wastewaters into sewers or into rivers, lakes or oceans. This applies to industries that generate wastewater with high concentrations of organic matter, toxic pollutants or nutrients such as ammonia. Some industries install a pre-treatment system to remove some pollutants, and then discharge the partially treated wastewater to the municipal sewer system.

<span class="mw-page-title-main">Zinc–air battery</span> High-electrical energy density storage device

A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste and form zincate, releasing electrons to travel to the cathode. The zincate decays into zinc oxide and water returns to the electrolyte. The water and hydroxyl from the anode are recycled at the cathode, so the water is not consumed. The reactions produce a theoretical voltage of 1.65 Volts, but is reduced to 1.35–1.4 V in available cells.

Although most lithium metal batteries are non-rechargeable, rechargeable lithium metal batteries are also under development. Since 2007, Dangerous Goods Regulations differentiate between lithium metal batteries and lithium-ion batteries.

<span class="mw-page-title-main">Battery Directive</span>

The Directive 2006/66/EC of the European Parliament and of the Council of 6 September 2006 on batteries and accumulators and waste batteries and accumulators and repealing Directive 91/157/EEC, commonly known as the Battery Directive, regulates the manufacture and disposal of batteries in the European Union with the aim of "improving the environmental performance of batteries and accumulators".

Aluminium–air batteries produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes. This has restricted their use to mainly military applications. However, an electric vehicle with aluminium batteries has the potential for up to eight times the range of a lithium-ion battery with a significantly lower total weight.

<span class="mw-page-title-main">History of the battery</span>

Batteries provided the main source of electricity before the development of electric generators and electrical grids around the end of the 19th century.

<span class="mw-page-title-main">Electric battery</span> Power source with electrochemical cells

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons. When a battery is connected to an external electric load, those negatively charged electrons flow through the circuit and reach to the positive terminal, thus cause a redox reaction by attracting positively charged ions, cations. Thus converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell.

The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow.

<span class="mw-page-title-main">Waste in the United States</span>

As a nation, Americans generate more waste than any other nation in the world, officially with 4.4 pounds (2.0 kg) of municipal solid waste (MSW) per person per day, with another study estimating 7.1 pounds (3.2 kg) per capita per day. Fifty five percent of this waste is contributed as residential garbage, while the remaining forty five percent of waste in the U.S.'s 'waste stream' comes from manufacturing, retailing, and commercial trade in the U.S. economy. According to the American Society of Civil Engineers, Nevada produces the most waste at "[nearly] 8 pounds (3.6 kg) per person per day". Approximately 90% of all waste produced by Nevadans ends up in landfills. "Wasteful" states Michigan, New Mexico, Wisconsin and Oregon as well as Washington also dominated the list's 5-year period.

A zinc-ion battery or Zn-ion battery (abbreviated as ZIB) uses zinc ions (Zn2+) as the charge carriers. Specifically, ZIBs utilize Zn metal as the anode, Zn-intercalating materials as the cathode, and a Zn-containing electrolyte. Generally, the term zinc-ion battery is reserved for rechargeable (secondary) batteries, which are sometimes also referred to as rechargeable zinc metal batteries (RZMB). Thus, ZIBs are different than non-rechargeable (primary) batteries which use zinc, such as alkaline or zinc–carbon batteries.

<span class="mw-page-title-main">Environmental impacts of lithium-ion batteries</span>

Lithium batteries are batteries that use lithium as an anode. This type of battery is also referred to as a lithium-ion battery and is most commonly used for electric vehicles and electronics. The first type of lithium battery was created by the British chemist M. Stanley Whittingham in the early 1970s and used titanium and lithium as the electrodes. Applications for this battery were limited by the high prices of titanium and the unpleasant scent that the reaction produced. Today's lithium-ion battery, modeled after the Whittingham attempt by Akira Yoshino, was first developed in 1985.

Disposable electronic cigarettes, also known as disposable vapes, combine various materials like plastics, metals, and electronic components, which present numerous environmental concerns. These single-use devices, while convenient, add to the growing problem of electronic waste due to their complex composition and the difficulties inherent in recycling mixed materials, especially those with lithium batteries. Beyond the waste management issues, disposable vapes contribute to resource depletion, environmental pollution through the potential release of toxic substances, and a not insignificant carbon footprint.

Our alkaline batteries are composed primarily of common metals – steel, zinc, and manganese – and do not pose a health or environmental risk during normal use or disposal. We have voluntarily eliminated all of the added mercury from our alkaline batteries since the early 1990s .... Therefore, alkaline batteries can be safely disposed of with normal household waste, everywhere [in the U.S.] but California.
