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。有害垃圾投(tou)放時，應注(zhu)意輕放：

1、廢舊燈管等易(yi)破損的有害垃圾應(ying)連帶包裝或(huo)包裹后投放。

2、廢棄藥品應連帶包(bao)裝一并投放。

3、殺(sha)蟲劑等壓力罐裝容器，應破(po)孔后投放。

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(hai)垃圾收集容器的標志為(wei)紅色，其中含汞(gong)廢(fei)棄物(wu)和(he)廢(fei)藥品(pin)需要分開丟棄。

二、紐扣電池回收處理方法

外形(xing)上分(fen)，紐(niu)扣(kou)(kou)電(dian)(dian)池(chi)分(fen)為柱狀(zhuang)電(dian)(dian)池(chi)、方形(xing)電(dian)(dian)池(chi)以(yi)及異形(xing)電(dian)(dian)池(chi)等。從能否充(chong)(chong)電(dian)(dian)來分(fen)，可分(fen)可充(chong)(chong)電(dian)(dian)的(de)和不充(chong)(chong)電(dian)(dian)的(de)兩種。其中，充(chong)(chong)電(dian)(dian)的(de)包括3.6V可充(chong)(chong)鋰離(li)子扣(kou)(kou)式(shi)電(dian)(dian)池(chi)，3V可充(chong)(chong)鋰離(li)子扣(kou)(kou)式(shi)電(dian)(dian)池(chi)(ML或VL系列)。不充(chong)(chong)電(dian)(dian)的(de)包括3V鋰錳扣(kou)(kou)式(shi)電(dian)(dian)池(chi)(CR系列)及1.5V堿性鋅錳扣(kou)(kou)式(shi)電(dian)(dian)池(chi)(LR及SR系列)。按材料分(fen)，紐(niu)扣(kou)(kou)電(dian)(dian)池(chi)可分(fen)為氧化銀(yin)電(dian)(dian)池(chi)、鋰電(dian)(dian)池(chi)、堿性錳電(dian)(dian)池(chi)等。

國家環(huan)境保護部門此前曾(ceng)明確規定，廢(fei)(fei)鎳鎘電(dian)池(chi)、廢(fei)(fei)含汞(gong)電(dian)池(chi)和(he)廢(fei)(fei)鉛(qian)酸蓄電(dian)池(chi)屬于危險(xian)廢(fei)(fei)物，需分類回收。但廢(fei)(fei)棄的(de)普通鋅錳電(dian)池(chi)和(he)堿性(xing)鋅錳電(dian)池(chi)不屬于危險(xian)廢(fei)(fei)物，尤(you)其(qi)是已(yi)基(ji)本達到無(wu)汞(gong)化的(de)廢(fei)(fei)電(dian)池(chi)（主要(yao)指一次性(xing)干電(dian)池(chi)），不鼓(gu)勵集(ji)(ji)中(zhong)收集(ji)(ji)。因為我國尚無(wu)專(zhuan)門設(she)施集(ji)(ji)中(zhong)處理這些電(dian)池(chi)，且(qie)處理技(ji)術不成熟(shu)。

市場上的非(fei)充電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)(chi)都符(fu)合無汞標準。所以(yi)大部分非(fei)充電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)(chi)可以(yi)隨生(sheng)活垃圾(ji)直接扔掉。但是(shi)可充電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)(chi)和紐扣電(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)一定(ding)要放(fang)進廢舊電(dian)(dian)池(chi)(chi)(chi)(chi)回收箱的。除了(le)堿性錳電(dian)(dian)池(chi)(chi)(chi)(chi)外(wai)，像(xiang)氧化銀電(dian)(dian)池(chi)(chi)(chi)(chi)、鋰(li)電(dian)(dian)池(chi)(chi)(chi)(chi)以(yi)及鋰(li)錳電(dian)(dian)池(chi)(chi)(chi)(chi)等類(lei)型的紐扣電(dian)(dian)池(chi)(chi)(chi)(chi)內部均存在有害物質(zhi)，會對環(huan)境造成污染，因(yin)此需要集中(zhong)回收處理，不可隨意丟棄。
