The Environment Bureau in Hong Kong is running a competition asking people to submit ideas on what to do with the growing number of deteriorated electric vehicle batteries on the island . Local green groups have been critical , arguing that so far there is no official consensus regarding what should be done with these batteries . Retired electric vehicle batteries still have up to 80 % of their electricity storage capacity in place so the government is hoping to identify the best applications for them beyond vehicle retirement , particularly as EVs in Hong Kong have grown in number by around 60 % since 2010 , reaching 5,800 units this July . One option being pursued is to require car manufacturers to implement battery recycling , disposal and recycling plans .
