With regard to your queryhousehold batteries can be dispose as other household waste.
Our concerns with the disposal of household batteries are mainly in the mercury content of batteries. Since 1992 Singapore has banned the sale of mercury oxide batteries zinc carbon batteries containing more than 0.001% by weight of mercury per battery and alkaline batteries containing more than 0.025% by weight of mercury per battery.
We do not have separate collection and disposal for batteries except for batteries used by vehicles and industries.The vehicle and industry batteries contain lead and are therefore harmful. Lead acid batteries are collected separately by licensed toxic waste collectors and recycled at overseas facilities. For consumer batterieswe can avoid the collection and disposal problems as we have already controlled the types of consumer batteries allowed to be sold. Hence consumer batteries are disposed of together with other wastes at the incineration plants.
You may wish to note that recycling bins available at the Nokia Care Centres are meant for old or used mobile phonesand mobile phone accessories and batteries. They don't collect household batteries.
