Recycling issue
Seeing all of the environmental impacts brought by batteries, one of the natural solution that we usually think about is to recycle the used battery.
Even with rechargeable batteries, they still lose their capacity after their lifecycle, that is why for us to minimize the manufacture and producing of the raw materials that are needed for a battery, we can recycle the used battery and use all the materials in there.
Nevertheless, the benefit of recycling is negligible when compared with the environmental burden that is caused during the process of recycling material and all the energy used during the process.
The recycling process includes collecting used batteries, processing it, and all of these processes will still result in emission that will damage our environment.
