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.
集成电池回收（BATINTREC）工艺是一种用于回收废旧电池和电子垃圾的创新技术，它将真空冶金再处理和铁氧体合成工艺结合在一起。真空冶金再处理可用于回收干电池中的汞（Hg）和镍镉电池中的镉（Cd）。铁氧体合成工艺通过在液相中合成铁氧体来回收其他重金属。在铁氧体合成工艺中还会产生氧化锰和炭黑的混合物。该工艺产生的废水可循环利用，从而显著减少其排放量。如果将粉碎的电池废料和粉末与FeSO4·7H2O的比例设定为1:6，废水的重金属含量可达到中国《污水综合排放标准》。该工艺不仅可以稳定重金属，还能从废物中回收有用资源。
