Batteries may contain hazardous metals and chemicals such as for example nickel cadmium, alkaline, mercury, nickel metal hydride and cause acid, which can contaminate the environment if not disposed properly. For example, when batteries containing cadmium is used in landfills, they will sooner or later melt and release the toxic material that will seep into water supplies, posing significant health risks for the people. This is the reason recycling batteries has become therefore important as it helps in avoiding pollution, and also saves resources. 

The Recycling Process: 

To begin with, the batteries to be recycled are grouped according to chemistries such as for instance nickel-cadmium, nickel-metal-hydride, lithium, alkaline an such like. The combustible material, such as for example insulation and plastics, is then removed with a gas fired thermal oxidizer, that will be the first faltering step in the process. Most recycling plants have scrubbers where in fact the fumes from the thermal oxidizer are neutralized to eliminate pollutants, providing clear, naked cells which contain platinum content. 

When they have been hacked into small pieces, the material in the batteries are then heated to liquefy. Black slag left by burned out non-metallic substances are scraped off with a slag arm, and different materials that settle according to weight are skimmed off. Some plants pour the liquid metals straight into (65 pounds) or 'hogs' (2,000 pounds) without breaking up on site, which are then sent to metal recovery plants to produce nickel, chromium and iron re-melt alloy for the production of other metal products. 

State and Federal Laws in the United States: 

The Mercury-Containing and Rechargeable Battery Management Act was passed in 1996 by the U.S. Congress which involves managed batteries such as Ni-CD batteries and sealed lead-acid batteries to: 

1. be easily removable from consumer products to produce it better to recover them for recycling 

2. include in the name the battery chemistry, the "three pursuing arrows" image, and an expression that instructs users to effectively sell or dispose the battery 

3. Give national uniformity in transport, storage, and selection 

4. phase out the usage of certain mercury-containing batteries 

The Rechargeable Battery Recycling Corporation (RBRC ): 

(www.rbrc.org) 

America Rechargeable Battery Recycling Corporation (RBRC) was put up in 1994 as a, public service company to greatly help and increase the recycling of lightweight rechargeable batteries such as for example Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH), Lithium Ion (Li-ion), and Small Sealed Lead. Rechargeable power users are also educated by it in regards to the benefits and supply of rechargeable battery recycling. Nevertheless, RBRC only recycles batteries that has RBRC Battery Recycling Seal. Companies, marketers and lovers or rechargeable batteries or products and services that utilize them may contact RBRC at licensee@rbrc.com for better answers. Other Contact Info:

Current Developments: 

The mercury decrease in batteries, which had already started in 1984, remains continued today. For example, batteries such as those containing alkaline have experienced about a 97 percent mercury decline, and newer types may contain about one-tenth the amount of mercury previously contained in the typical alkaline battery, or may be zero-added mercury. Several mercury-free, heavy-duty, carbon-zinc batteries are now available as alternatives. Technology such as for example silver-oxide and zinc-air button batteries include less mercury so that they are beginning to change mercuric-oxide batteries. Nickel-cadmium batteries could be reprocessed to retrieve the nickel, and nickel-hydride process and cadmium free nickel will also be being explored. Currently, many nickel-cadmium batteries are permanently sealed in devices but changes are being made in regulations that may result in a recycling of nickel-cadmium batteries and more convenient retrieval.
