Yesterday's Battery Case. Today's Pellet.
The case comes off the battery, gets washed of acid and lead, shredded and pelletized. Injection grade, black or natural, sold by the 20 MT lot.
From battery casing to injection-grade pellet.
Our recycled polypropylene is sourced exclusively from lead-acid battery casings processed at our facility. Each casing is separated during the battery breaking stage, then cleaned to remove residual acid and lead contamination, shredded to uniform particle size, and pelletized for consistent feed in injection molding equipment. Nothing is bought in, which is what keeps the loop closed.
Recovery quality
Cleaned before shredding
Each casing is separated during the battery breaking stage, then cleaned to remove residual acid and lead contamination.
Reported per lot
Residual lead is checked by OES. Lot-specific MFI and ash content are reported on each Certificate of Analysis.
Uniform pellet feed
Shredded to uniform particle size and pelletized for consistent feed in injection molding equipment.
Built for industrial injection molding.
Molders run it for pallets, crates, automotive trim and construction profiles. We ship it from the same campus that refines the lead.
Common uses include automotive parts, industrial containers, cable management components, construction materials, and general-purpose plastic goods. The material offers consistent melt flow properties and mechanical strength appropriate for non-critical structural applications.
Available in both black and natural color, the material can be compounded with additives or colorants to meet specific application requirements. MFI (Melt Flow Index) data is available upon request for your engineering team to evaluate suitability.
