  • Title: The BATINTREC process for reclaiming used batteries.
    Author: Xia YQ, Li GJ.
    Journal: Waste Manag; 2004; 24(4):359-63. PubMed ID: 15081063.
    Abstract:
    The Integrated Battery Recycling (BATINTREC) process is an innovative technology for the recycling of used batteries and electronic waste, which combines vacuum metallurgical reprocessing and a ferrite synthesis process. Vacuum metallurgical reprocessing can be used to reclaim the mercury (Hg) in the dry batteries and the cadmium (Cd) in the Ni-Cd batteries. The ferrite synthesis process reclaims the other heavy metals by synthesizing ferrite in a liquid phase. Mixtures of manganese oxide and carbon black are also produced in the ferrite synthesis process. The effluent from the process is recycled, thus significantly minimizing its discharge. The heavy metal contents of the effluent could meet the Integrated Wastewater Discharge Standard of China if the ratio of the crushed battery scrap and powder to FeSO4.7H2O is set at 1:6. This process could not only stabilize the heavy metals, but also recover useful resource from the waste.
