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。有害垃圾投放時，應注意(yi)輕放：

1、廢(fei)舊燈(deng)管等易破損的有害垃(la)圾應(ying)連帶包(bao)裝或(huo)包(bao)裹后投放。

2、廢棄藥品應連帶包裝一(yi)并投(tou)放。

3、殺蟲劑等壓力(li)罐裝容(rong)器(qi)，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。有害垃圾收集容器的(de)標(biao)志為紅色，其中含汞廢(fei)棄(qi)物和(he)廢(fei)藥品需要(yao)分開(kai)丟棄(qi)。

二、紐扣電池回收處理方法

外形上分，紐(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)池(chi)分為柱狀(zhuang)電(dian)(dian)(dian)(dian)池(chi)、方形電(dian)(dian)(dian)(dian)池(chi)以及(ji)(ji)異形電(dian)(dian)(dian)(dian)池(chi)等。從能(neng)否充電(dian)(dian)(dian)(dian)來分，可(ke)分可(ke)充電(dian)(dian)(dian)(dian)的和不(bu)充電(dian)(dian)(dian)(dian)的兩種(zhong)。其中，充電(dian)(dian)(dian)(dian)的包括(kuo)3.6V可(ke)充鋰離子(zi)扣(kou)(kou)式電(dian)(dian)(dian)(dian)池(chi)，3V可(ke)充鋰離子(zi)扣(kou)(kou)式電(dian)(dian)(dian)(dian)池(chi)(ML或VL系列(lie)(lie))。不(bu)充電(dian)(dian)(dian)(dian)的包括(kuo)3V鋰錳(meng)扣(kou)(kou)式電(dian)(dian)(dian)(dian)池(chi)(CR系列(lie)(lie))及(ji)(ji)1.5V堿性(xing)鋅錳(meng)扣(kou)(kou)式電(dian)(dian)(dian)(dian)池(chi)(LR及(ji)(ji)SR系列(lie)(lie))。按材料分，紐(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)池(chi)可(ke)分為氧化銀電(dian)(dian)(dian)(dian)池(chi)、鋰電(dian)(dian)(dian)(dian)池(chi)、堿性(xing)錳(meng)電(dian)(dian)(dian)(dian)池(chi)等。

國(guo)家環境保(bao)護部門此前曾明確規定，廢(fei)(fei)(fei)鎳鎘電池(chi)、廢(fei)(fei)(fei)含汞電池(chi)和(he)廢(fei)(fei)(fei)鉛(qian)酸蓄(xu)電池(chi)屬于危險(xian)廢(fei)(fei)(fei)物(wu)，需分(fen)類回收。但廢(fei)(fei)(fei)棄的普通鋅錳電池(chi)和(he)堿性鋅錳電池(chi)不(bu)屬于危險(xian)廢(fei)(fei)(fei)物(wu)，尤(you)其是已基本達到無(wu)(wu)汞化的廢(fei)(fei)(fei)電池(chi)（主要指一次性干(gan)電池(chi)），不(bu)鼓勵集(ji)(ji)中(zhong)(zhong)收集(ji)(ji)。因為我國(guo)尚無(wu)(wu)專(zhuan)門設施集(ji)(ji)中(zhong)(zhong)處理這(zhe)些(xie)電池(chi)，且處理技(ji)術不(bu)成熟。

市場上的(de)非充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)都符(fu)合無汞(gong)標準(zhun)。所以(yi)大部分非充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)可(ke)以(yi)隨(sui)生活(huo)垃圾直接扔掉。但是(shi)可(ke)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)和(he)紐(niu)(niu)扣電(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)一定要放(fang)進廢舊電(dian)(dian)(dian)池(chi)(chi)(chi)回收箱的(de)。除了堿性錳電(dian)(dian)(dian)池(chi)(chi)(chi)外，像(xiang)氧化銀(yin)電(dian)(dian)(dian)池(chi)(chi)(chi)、鋰電(dian)(dian)(dian)池(chi)(chi)(chi)以(yi)及鋰錳電(dian)(dian)(dian)池(chi)(chi)(chi)等類型的(de)紐(niu)(niu)扣電(dian)(dian)(dian)池(chi)(chi)(chi)內部均存在有害(hai)物質(zhi)，會對環境造成污(wu)染(ran)，因此需要集中回收處(chu)理，不可(ke)隨(sui)意(yi)丟棄。
