Recycling of Lead-Acid Batteries in Developing Countries
Lead-acid batteries ( also known as LABs) are a common item in our day-to-day lives. Once the lead of the battery is timed out, we’ve no option but to dispose of it because it has no use for us currently, but the copper plates in the battery remain reusable which can be used for recycling. There are some disagreements about the benefits of recycling batteries, say alkaline batteries, over simple disposal because the mercury in the battery no longer exists and the disposal material is abundant and non-toxic. But for automotive batteries the situation is different in terms of benefits. The recycling of this type of battery holds both profitable and environmental benefits.
The functional material from the used battery is removed and reclaimed which reduces the essentials for raw outfit which is originally imported from abroad. It creates a balance between payment and cost. In addition to this there can be considerable environmental impact during mining processes like emission from smelting of sulfide ore, copper, nickel, and cobalt and this can be eliminated if recycling can be introduced.
Dangers of Lead-Acid Batteries
LABs generally have a chord of both sulphuric acid and a large measure of lead which isn’t only acrid but also a good carrier for resolvable lead and lead grains. Lead is considerably poisonous metal which causes a wide range of adverse health effects especially on juvenilechildren.However, crab hearing, and can lead to different other associated problems, If one gets exposed overly to lead it can bring about damage to brain and kidney. On a normal car manufactured contain about 12 kg of lead, in which about 96% of lead is used in the foremost acid battery and remaining 4 is used in other exercises like wheel balance weight, defensive coating and variation mutes.
Both lead and cadmium are damaging for human health and climate. This poison seeps into the soil, groundwater and river water through landfill and also releases poisons into the air when they’re burnt in public waste incinerators. more cadmium can be freely absorbed by the plant root and get into the fruits, vegetables, and waters consumed by animals and human beings, they can fall prey to a host of ill things.
Studies have shown that nausea, extreme salivation, abdominal pain, liver and kidney damage, skin problem, headaches, asthma, anxiousness, low IQ in children, and sometimes cancer can result from exposure to such matter for a sufficient period of time.
Need for Effective Control Measures
In a battery recycling plant, effective control measures need to be applied, both to cover the health of workers and to avoid pollution of nature. Good factory design, with reduction of the eventuality for the outflow of defiling substances is of utmost significance and the newer smelting processes are naturally much cleaner than traditional blast furnaces.
Pollution abatement technologies, including the treatment of exhaust gases and liquid effluents, need to be installed. Those generally exposed to releases within the factories are the help. Control measures cognate as maintaining littlest ethos of air quality within the manufactory, medical surveillance of hirelings, use of defensive outfit, and provision of conditions of good hygiene in general, is necessary to avoid occupational lead exposure. Notwithstanding, legion government/non-governmental lines have been taken yet; rather this practice is a traditional trading system that prevails in the society.
Positive and Negative Impacts
In developing countries connate as Bangladesh, reclaiming or reusing of given lead-acid batteries has both positive and negative impact on context. Positive impact is that, if battery is reclaimed in proper and in a sustainable manner it saves context from poison material of battery, otherwise battery waste is blown off into the landfills. Negative impact is that if recycling isn’t done in sustainable manner emits gases produced from battery recycling has adverse impacts on environment and human being.
Direct recycling process should be banned as it has an adverse impact on nature. As it’s an illegal process, shopkeepers perform this process in a secret way. Government should impose the law and regulation strictly in this happening. This information can be used for advertising material featuring the environmental benefits of recycling or reusing encourages the purchasing of old lead acid batteries. It’ll accelerate the selling rate of old batteries.
priority of Attention
Necessary Track should be taken to increase awareness about environmental impacts of used lead acid batteries. Proper instruction should be delivered among the general mass. It’ll also increase reusing of old batteries. Battery regeneration is a unique process specially designed to revive the lost capacity of batteries and give importance to choosing a secondary battery. Battery Reuse Centre can be developed for effective recycling and reuse.
The Target to divert recyclable batteries, contributed by the public, which oft could have been predetermined for landfill and instead provides a significant required source of low- cost battery to those in need. The battery recycle service encourages volunteer involvement and trainee placements in all aspects of its operation. Awareness program ( placards, brochures, TV & radio commercials, road- shows, website, exhibitions, speeches), Buildings, information center, tax rebates for manufacturers should be taken to increase recycling or reusing of old battery
