Recycling batteries is an ecologically friendly alternative to simply throwing them in the garbage only to have them end up in landfills.
Batteries contain a number of heavy metals and toxic chemicals, and disposing of them using conventional methods raises proven environmental concerns. Recycling batteries is an ecologically friendly alternative to simply throwing them in the garbage only to have them end up in landfills. Our battery recycling program offers the convenience of disposing of your spent batteries along with peace of mind knowing that you're positively contributing to environmental and public health. No matter your type of batteries, we ensure that their contents do not end up in your municipalities' soil or ground water. The types of batteries that the environmental services professionals at Aevitas recycle are:
Alkaline batteries are shredded and neutralized using sulfuric acid generated from acidic batteries. The neutralized waste product is drained and dried, then mixed with carbon based steel turnings and sent to a steel furnace to be incinerated. The zinc portion of the battery is set aside and sent for zinc recovery. This process for recycling alkaline batteries ensures that the carbon and other components of the battery can be reused in steel production.
Lead acid batteries
Lead acid batteries are crushed then enters what is known in the recycling industry as a sink float separation system. This separates the batteries' lead from its plastic casing which is recovered, washed and extruded into pellets that are used in the manufacturing of new battery casings. The batteries lead is put through a smelting process to produce ingots that are used to produce new lead battery plates. This entire process is a viable and ecologically sound method of lead battery recycling.
Lithium batteries are cooled to -325 F in order to deactivate the lithium within them, then the batteries are shredded and neutralized. Their lithium salt is reclaimed and sent for refining into lithium metal, used primarily for the production of new lithium batteries.
Mercury batteries are heated to 700 F in a mercury retort oven which causes their mercury to fume off as a vapour, which is then recovered and condensed. The mercury is then triple distilled to produce pure elemental mercury.
Nickel and cadmium batteries
Nickel and cadmium are recovered separately using a pyrometallurgical process. Cadmium is recovered as sticks and balls for reuse primarily in the manufacturing of new Ni-Cad batteries. Nickel is recovered in the form of ingots suitable for reuse in the stainless steel industry.
Silver oxide batteries
Although not very common (a ratio of 1 lb of silver oxide batteries to 400,000 lbs of hazardous waste), silver oxide batteries are sent for precious metal recovery where the silver is reclaimed and reused.
