How and where to dispose of batteries in a sustainable way?

where to dispose batteriesThe battery technology just like solar PV technology continues to advance and today there are various types of batteries being used to help power equipment or store energy for electricity. As the solar PV sector continues to grow whether with on-grid or off-grid solar applications; the battery technology will help to accelerate the increased adoption of solar PV in domestic, commercial and utility sectors and other renewable energy technologies that are intermittent in nature like the wind energy.
Similarly, with the rapid development of electric cars in various countries, it means that we will see the demand for battery technology continue to grow exponentially. Solar PV and electric vehicles(EV) will definitely demand increased usage of the battery technology among other sectors that require batteries such as agricultural, commercial or even the household sector where batteries are used for TV remotes, flashlights, children’s toys and small electronics like cellphones.

However, even with these technological developments; how and where to dispose of batteries after their useful life is completed is one aspect of sustainability that will need to be tackled from a system thinking perspective. At the development stage of these batteries, it calls for implementing sustainable design to make it easy to recycle most of the components of the battery technology in question. For instance, researchers at the IBM research unveiled recently a new battery technology that will eliminate the need for heavy metals in battery production hence improving sustainable design.

As such, before looking into proper ways of disposing batteries, it is good to know what batteries are, the different types of batteries, and what they are made up of, making them something that requires proper disposal. Well, batteries are a collection of one or a group of cells that undergo various chemical reactions to create a continuous flow of electrons in a circuit.

Battery cells are generally classified into three components that is the anode, also known as the negative electrode, cathode, also known as the positive electrode, and finally, the electrolytes. For sustainability, the battery chemical composition will matter as it will guide how a battery will be disposed of after its useful life. For instance, in the USA, when it comes to lead-acid batteries, 99% of these batteries are collected and recycled.

However, according to the World Economic Forum, recycling lithium-ion batteries is a bit challenging due to the diversity of cell types and the broad range of materials such as an alloy of cobalt, nickel, and copper that may require manual sorting and handling or even smelting (pyrometallurgy) to recover individual metals or battery raw materials such as cobalt carbonate.

Types of batteries

There are many types of batteries classified according to their chemical composition, formation factor, size, and the purpose they serve. They include:

  1. Primary batteries: These are a kind of batteries that cannot be recharged once fully used. These batteries are made up of electrochemical cells that their electrochemical reactions can also not be reversed. This kind of battery is usually used in devices that require no charging. Primary batteries are made up in a way that they provide high specific energy, and whenever used, the devices consume little power to ensure the battery has a long life span. The most common kind of primary batteries is alkaline batteries. They have higher specific energy levels, are environmentally friendly, and are cheaper to purchase.
  2. Secondary batteries are the direct opposite of primary batteries. Secondary batteries can be recharged, and their electrochemical cells and electrochemical reactions can be reversed when all the energy has been fully used up. The secondary batteries are commonly known as the rechargeable batteries. Secondary batteries can be classified into different groups depending on their chemistry or chemical composition.
    1. Lithium-ion: they are also known as Li-ion batteries. They are used in smart devices such as mobile phones and other battery home appliances. It has Lithium electrodes on it.
    2. Nickel Cadmium: Also known as Ni-Cd batteries. They are made up of nickel oxide hydroxide chemical and the metallic cadmium as the electrodes.
    3. Nickel-Metal hydride. This kind of batteries has the same chemical reaction to Ni-Cd batteries, which is nickel oxide hydroxide. Although, a negative electrode uses hydrogen-absorbing alloy, but not cadmium like the Ni-Cd batteries.solar battery
    4. Lead-acid batteries: Lead-acid batteries are cheaper efficient power batteries that are used in heavy-duty applications. They are usually used in instances where they are non-portable because of their weight. Lead-acid batteries are used in an application that includes vehicle batteries for ignition and lighting and also as solar-panel energy stores. Lead-acid batteries are made up of acid that is used to ensure proper current flow in the circuit. Lead-acid batteries are the oldest form of secondary batteries and are relatively cheap compared to the other secondary batteries.

Where to dispose of batteries

Batteries are disposed of depending on the type which determines their chemical composition.

a) Household batteries: Household batteries can be classified into two groups, either rechargeable or non-rechargeable batteries. Disposing of the household batteries is not as complicated as disposing of the vehicle and industrial batteries.

According to battery solutions, alkaline batteries (AAA, AA, C, D, 9V, etc.) can be recycled using a specialized “room temperature,” mechanical separation process to recycle alkaline batteries.

The alkaline battery components are separated into three end products, that is, a zinc and manganese concentrate, steel, and paper, plastic and brass fractions. All of these products are put back into the market place for reuse in new products to offset the cost of the recycling process.

However, when it comes to rechargeable batteries, for example, lithium batteries are recyclable. They can, therefore, be disposed of at the battery recycling centers, electronic retailers who recycle batteries, or a waste collection site for hazardous materials. Therefore, ensuring you dispose of batteries properly.

b) Industrial batteries.

Industrial batteries can also be referred to as forklift or traction batteries. Industrial batteries can normally be drained to about 20% of the maximum charging capacity before a recharge.

Industrial batteries are manufactured with lead plates making them not disposable in the trash. Lead is considered to be a hazardous waste that is highly toxic to the environment. So when it comes to the industrial batteries, an estimated 60 to 80 percent of the used battery is normally reclaimed. More than 95 percent of the industrial lead-acid batteries are recycled.

The outer plastic shell is recycled to make some new plastic items, whereas the metal plates undergo purification to manufacture new batteries. In most states, there is a law that accepts the return of the industrial batteries to the retailer for disposal purposes. In case one cannot trace the retailer, they can contact the government officials for the information on the directions to follow to ensure proper disposal of the industrial batteries, industrial batteries maybe containing sulphuric acid that is harmful.

Safety precaution is normally advised when transporting the batteries for disposal. One should also avoid exposing the batteries to open flames or incidental devices like the cigarette lighters just for precaution measures.

c) Vehicle batteries: Car batteries are made out of lead-acid which is hazardous. It is, therefore, essential to dispose of it carefully just to avoid harmful side effects that can be life-threatening to human beings. There are many ways to dispose of vehicle batteries.
where to dispose batteries

  • Returning the battery to a retailer. When purchasing the battery, there is normally a core charge fee certain retailers usually add in the receipts. This charge means that the battery is essential to the retailer. It can either be recycled or be rebuilt. Meaning that you can return the battery to the retailers, and they refund back your money with the same amount you paid as a core charge fee.
  • Taking the car battery to a recycling depot: You can check on the closest designated recycling depots near you on the internet and dispose of your car battery there for disposals.
  • Taking the car battery to an auto parts store: You can make your take battery to an auto parts store as you go buy another one.
  • Selling the car battery to scrap metal depot: One can decide to sell their batteries off to the scrap metal depot near them at a fee.
  • Taking the car batteries to battery recycling centers where they can recycle them and make something good out of them.

Each state has its own recycling program while resources such as Earth911 have a comprehensive online platform for helping online users decide on how to dispose of old batteries. Earth911 provides a recycling locator for all types of batteries where you just enter your zip code and it pulls the details for your specific battery and how or where to recycle them.

Call2Recycle is another online resource that offers a network of over 34,000 local recycling centers and drop-off locations for rechargeable batteries such as local municipalities and local retailers like Best Buy.

What is the cost of solar panels?

what is the cost of solar panelsThe solar photovoltaics (PV) technology continues to advance every year and its applications are increasing ranging from on-grid solar, off-grid solar, hybrid solar (PV), and portable solar solutions.

All these applications use solar PV technology as the primary component to generate solar electricity for homes or commercial places. As a result, the cost of solar panels is the main driver of the price of such systems despite whether they are on-grid, off-grid, hybrid, or even portable applications.

Since the year 2010, the price for solar panels has declined by over 70% and continues to decrease by at least 10% every year. Today(2020), the average price per watt for solar panels ranges from $2.57 to $3.35 according to EnergySage.

Comparing this price to the price of solar panels of about $76.67/watt in 1977, the cost of solar panels has declined by over 99% resulting to the use of solar panels to big equipment like 2000MW utility-scale solar PV power plants to even on very small gadgets like solar cell phone chargers.

The goal of research and development (R&D) is to reach higher efficiency and lowered solar panel costs. In addition to first-generation solar panels (wafer-based solar panels), R&D efforts have introduced second-generation solar panels which are the thin-film solar panels and third-generation solar panels that incorporate organic materials such as organometallic compounds and inorganic materials.
