Recycling industry frequently causes pollution to the environment. It is either the same or more than any other industrial activities. Lead acid batteries recycling is a typical industry causing environmental pollution in developing countries.
Recycling of Lead Acid Battery is one of the most hazardous jobs. Since it became difficult to process lead in the plant due to public opposition, some informal operators used drums in stead of smelting furnace to heat batteries by propane to melt electrolyte lead to recover lead without any pollution control. They conducted such operations underground, in a most clandestine manner. Secondary lead refining process is a batch process based on traditional pyro- metallurgical methods. Batch refining is carried out in hemispherical vessel usually stirred to mix the reactants. The metal is held molten while reaction products float out and recovered from the surface. These systems typically have no pollution control system. However, lead of purity of 99.99percent is recovered in these units.
Some of the pollution related issues include air and water pollution and solid waste management. During the processing of spent lead-acid battery in backyard units, operations like breaking, crushing, screening, dry mixing etc. generate airborne lead dust which directly or indirectly enter into the human system and the surroundings of the working area. Effluent discharge occurs during battery treatment. Since lead is a very toxic material, disposal of the solid wastes from secondary lead production in the secured landfill is essential and mandatory.
Recycling is considered to be good for the environment. But some material recycling processes cause environmental pollution, if proper pollution control measures are not applied. Relocation of the factory without any pollution control does not provide solution to the problem. If recycling plant is willing to invest in pollution control, information of pollution control technologies should be provided. If possible, financial support such as low interest loan can promote such investment.
