The lead paste in spent lead-acid batteries holds precious regenerated lead resources, yet it was once a thorny problem in recycling and disposal. Today, innovative technologies are paving a green path for this "waste" to be reborn.
Clean Technologies Unlock Resource Potential
Gone are the days of high-pollution traditional methods for lead paste regeneration. Modern processes prioritize high efficiency and environmental friendliness. From hydrothermal reduction technology that uses glucose to efficiently convert lead compounds, to the low-carbon route of ammonium sulfate-ammonia suspension electrolysis, and the clean refining of methanesulfonic acid systems, every step embodies technological ingenuity. These processes skip the energy-intensive high-temperature smelting stage. By precisely controlling reaction conditions, the lead recovery rate easily exceeds 98%, and the purity of regenerated lead reaches over 99%.
Circular Value and Ecological Benefits Go Hand in Hand
Supported by advanced technologies, the entire lead paste regeneration process achieves low emissions and low energy consumption. At the end of the reaction, not only high-purity metallic lead can be recovered, but also reusable by-products such as sulfuric acid can be obtained, truly turning waste into treasure. For every 1kg of spent lead paste recycled, hundreds of kilograms of carbon dioxide emissions can be reduced. This not only eases the pressure of lead resource shortage, but also safeguards the ecological environment.
