For common dry batteries, please put them directly in the official trash bin and do not collect them centrally (referring to qualified alkaline batteries, lithium batteries, nickel-hydrogen batteries);
Batteries with high levels of harmful substances include carbon-zinc batteries (cheap dry batteries before 2005), most button batteries, nickel-cadmium batteries (old-fashioned rechargeable batteries), etc.
If there is a waste battery recycling agency nearby, please give it to them (for example, some neighborhood committees, environmental protection associations of universities, etc.).
If there is no recycling agency nearby (for example, most cities and villages), and the number of batteries is large, you can contact the local environmental protection bureau or mail it to other cities. For example, the Second Cleaning Branch of Beijing Environmental Sanitation Engineering Group Co., Ltd. (including address and telephone number) will collect more than 30 kilograms of waste batteries free of charge.
If there is no recycling facility nearby, and the number of batteries is small, please seal them and keep them until the recycling facility is found.
In particular, if a large number of dry batteries have been collected, please classify them and deal with them separately according to the above recommendations. Neither should all types of used batteries be handed over to the environmental protection department ("in the absence of effective recycling technology and economy, the government does not encourage the centralized collection of waste disposable batteries that meet the national requirements for low or no mercury"), nor should any type of dry batteries be discarded blindly (some types of pollution are harmful to the environment and health) Kang.
