一、紐扣電池是什么垃圾分類

紐扣電池是屬于有害垃圾。有害垃圾指廢電池、廢燈管、廢藥品、廢油漆及其容器等對人體健康或者自然環境造成直接或者潛在危害的生活廢棄物。有害(hai)垃圾投放時，應注意輕放：

1、廢舊燈管等易(yi)破損的有害垃圾應連帶(dai)包裝或(huo)包裹后投(tou)放。

2、廢棄(qi)藥(yao)品應(ying)連帶包裝一并投放。

3、殺蟲劑等壓力(li)罐裝容(rong)器(qi)，應破孔后(hou)投放。

4、在公共場所產生有害垃圾且未發現對應收集容器時，應將有害垃圾攜帶至設置有害垃圾收集容器的地點妥善投放。有害垃圾收集容器(qi)的(de)標志(zhi)為(wei)紅色，其中(zhong)含汞廢棄物(wu)和廢藥品(pin)需要分開丟棄。

二、紐扣電池回收處理方法

外形上分(fen)，紐扣(kou)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)分(fen)為柱(zhu)狀(zhuang)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、方形電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)以(yi)及(ji)異形電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)等。從能否(fou)充電(dian)(dian)(dian)(dian)來(lai)分(fen)，可分(fen)可充電(dian)(dian)(dian)(dian)的(de)(de)和不(bu)充電(dian)(dian)(dian)(dian)的(de)(de)兩種(zhong)。其中(zhong)，充電(dian)(dian)(dian)(dian)的(de)(de)包括3.6V可充鋰離子扣(kou)式(shi)(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，3V可充鋰離子扣(kou)式(shi)(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(ML或VL系列)。不(bu)充電(dian)(dian)(dian)(dian)的(de)(de)包括3V鋰錳扣(kou)式(shi)(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(CR系列)及(ji)1.5V堿性鋅錳扣(kou)式(shi)(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(LR及(ji)SR系列)。按材料分(fen)，紐扣(kou)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)可分(fen)為氧化銀電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、堿性錳電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)等。

國家環境保護部門此前曾(ceng)明(ming)確(que)規(gui)定，廢(fei)(fei)鎳鎘電池(chi)(chi)、廢(fei)(fei)含汞(gong)電池(chi)(chi)和(he)廢(fei)(fei)鉛(qian)酸蓄電池(chi)(chi)屬(shu)于危險廢(fei)(fei)物(wu)，需(xu)分類(lei)回收。但廢(fei)(fei)棄的(de)普通鋅錳(meng)電池(chi)(chi)和(he)堿性鋅錳(meng)電池(chi)(chi)不(bu)屬(shu)于危險廢(fei)(fei)物(wu)，尤其是已基本達(da)到無汞(gong)化的(de)廢(fei)(fei)電池(chi)(chi)（主要指一次性干電池(chi)(chi)），不(bu)鼓勵集中收集。因為我國尚無專門設施(shi)集中處(chu)理這些電池(chi)(chi)，且處(chu)理技術(shu)不(bu)成熟。

市場上的非充電(dian)電(dian)池(chi)(chi)(chi)(chi)都符合無汞標準。所(suo)以(yi)大部分非充電(dian)電(dian)池(chi)(chi)(chi)(chi)可以(yi)隨(sui)(sui)生活垃圾直(zhi)接扔掉。但是可充電(dian)電(dian)池(chi)(chi)(chi)(chi)和紐(niu)扣(kou)電(dian)池(chi)(chi)(chi)(chi)是一(yi)定(ding)要(yao)放進廢舊電(dian)池(chi)(chi)(chi)(chi)回(hui)收箱(xiang)的。除了堿(jian)性錳電(dian)池(chi)(chi)(chi)(chi)外，像氧化銀電(dian)池(chi)(chi)(chi)(chi)、鋰(li)電(dian)池(chi)(chi)(chi)(chi)以(yi)及鋰(li)錳電(dian)池(chi)(chi)(chi)(chi)等(deng)類型的紐(niu)扣(kou)電(dian)池(chi)(chi)(chi)(chi)內部均存(cun)在有(you)害(hai)物質，會對(dui)環境造成污染，因此(ci)需(xu)要(yao)集中(zhong)回(hui)收處理(li)，不可隨(sui)(sui)意丟(diu)棄。
