Polypropylene Recovery from Lead Acid Battery Scrap: an Innovative Approach by GME Recycling

Polypropylene, a commonly used plastic in battery casings, has historically posed a significant challenge in the recycling process due to its complex composition. Recent advancements have revolutionized polypropylene recovery from discarded lead-acid batteries. GME has developed an innovative recycling plant that not only shreds, washes, and decontaminates polypropylene, achieving an impressive purity level of <200 ppm of lead, but also employs advanced sorting and separation techniques, such as wavelength-viewer based for color detection, to efficiently isolate and extract polypropylene components. The output from the plant is available in two forms: PP Chips (approximately 10mm in size) and PP Granules (approximately 1mm in size). This innovative approach diverts significant amounts of plastic waste from landfills, enabling the reuse of polypropylene in various industries, thus reducing the demand for virgin plastics and conserving valuable resources. This paper presents a detailed study of the polypropylene recovery process and highlights GME's contributions to a sustainable and circular economy.
