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 .

For example, recycling one ton of plastic in a closed-loop system saves about 7.4 cubic yards of landfill space. Since the grocery industry demonstrated [ when? ] that consumers use at least 690,000 tons of plastic in a year, universal implementation of ideal closed-loop recycling systems could save at least 5.1 million cubic yards of landfill ...
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Geographic distribution of critical minerals for Li-ion batteries. The electric vehicle battery accounts for 30–40% of the value of the vehicle. [1] Around one-third of the battery's weight is the housing and cooling system. The cathode makes up another 20% and the anode another 10%. [2] Three types of batteries dominate the electric vehicle ...
The large variation in size and type of batteries makes their recycling extremely difficult: [7] they must first be sorted into similar kinds and each kind requires an individual recycling process. Additionally, older batteries contain mercury and cadmium, harmful materials that must be handled with care. Because of their potential ...
Process flow chart. The terms mechanical biological treatment or mechanical biological pre-treatment relate to a group of solid waste treatment systems.These systems enable the recovery of materials contained within the mixed waste and facilitate the stabilisation of the biodegradable component of the material.
The recycling process, on the other hand, as suggested by Ciez and Whitacre emits a significant amount of GHG. As shown in the battery recycling emission plot a and c, the emission of the recycling process varies with the different recycling processes, different chemistry and different form factor.
The EPA has guidelines regarding recycling lithium batteries in the U.S. There are different processes for single-use or rechargeable batteries, so it is advised that batteries of all sizes are brought to special recycling centers. This will allow a safer process of breaking down the individual metals that can be reclaimed for further use. [23]
