Al­ka­line bat­ter­ies pose prob­lem for en­vi­ron­ment

China Daily (Canada) - - NEWS CAPSULE -

Al­ka­line-based bat­ter­ies are a prob­lem in China be­cause the coun­try has yet to for­mu­late wide-rang­ing, en­vi­ron­men­tally safe meth­ods of dis­posal.

Since 2004, China has been the world’s largest pro­ducer of bat­ter­ies, and in 2014, the na­tion’s an­nual pro­duc­tion of al­ka­line bat­ter­ies reached 13.8 bil­lion, ac­cord­ing to sta­tis­tics from the China In­dus­trial As­so­ci­a­tion of Power Sources, an in­dus­try as­so­ci­a­tion.

Ac­cord­ing to some sci­en­tists, one AAA al­ka­line bat­tery has the ca­pac­ity to pol­lute 1 square me­ter of soil, while one but­ton cell (the flat bat­ter­ies used in many types of cam­eras) could pol­lute 600 tons of wa­ter, roughly equal to the amount each per­son con­sumes in a life­time.
