Zinc is one of the most versatile and widely used non-ferrous metals, known for its corrosion resistance, malleability, and recyclability. As an essential industrial metal, zinc plays a critical role in galvanizing steel, die-casting, alloy manufacturing, and chemical production. At Sakthi Metals Waste Trading LLC, we specialize in sourcing, processing, and trading high-quality zinc scrap from around the world, serving industries that demand both performance and sustainability.
With an unwavering commitment to quality, reliability, and environmental responsibility, Sakthi Metals has become a trusted name in the global zinc recycling market, bridging suppliers and consumers through efficient trade networks and ethical sourcing practices.
Zinc (chemical symbol Zn) is a bluish-white, lustrous metal with a melting point of 419.5°C and density of 7.13 g/cm³. It is widely used in alloys such as brass and zamak, as well as for galvanizing steel to prevent rusting.
Zinc is 100% recyclable without any degradation in quality. Recycling zinc requires significantly less energy—around 60–75% less—than primary production from ores like sphalerite (ZnS), making it a key contributor to a low-carbon circular economy.
Zinc scrap typically originates from die-cast components, galvanizing residues, roofing sheets, and industrial machinery, all of which can be recovered, processed, and reused efficiently.
Sakthi Metals Waste Trading LLC trades and supplies a broad range of zinc scrap categories in compliance with ISRI (Institute of Scrap Recycling Industries) specifications. Our most commonly traded grades include:
New Zinc Die-Cast Scrap (ISRI Code: SAVES)
Clean, uncoated die-cast zinc pieces, free from impurities and iron attachments, often sourced from manufacturing offcuts.
Old Zinc Die-Cast Scrap (ISRI Code: SCOOT / SCORE)
Used zinc die-cast items such as automotive parts, hardware, and machinery components that can be re-melted and purified.
Zinc Dross (ISRI Code: BOTTOM / TOP DROSS)
A by-product from the hot-dip galvanizing process containing a mixture of zinc and iron. It is reprocessed to recover high-purity zinc.
Zinc Ash (ISRI Code: ZINC ASH / SKIMMINGS)
Residual zinc-rich dust and oxide collected from galvanizing and melting processes, suitable for zinc oxide production.
Zinc Ingots and Remelted Zinc
Recycled zinc that has been refined and cast into ingots, used by foundries and die-casting industries.
Mixed Zinc Scrap
A blend of various zinc materials from industrial waste, sorted and processed according to purity and composition.
At Sakthi Metals, zinc scrap recycling is carried out with precision, technology, and environmental consciousness. Our processes follow globally recognized standards to ensure maximum recovery and minimum environmental impact.
The key stages of zinc recycling include:
Collection and Sorting:
Zinc scrap is collected from manufacturers, construction sites, galvanizing plants, and industrial units. It is meticulously sorted based on purity, type, and physical form.
Pre-Treatment:
Contaminants such as paint, oil, and steel attachments are removed using mechanical and chemical cleaning methods to ensure clean feedstock for melting.
Melting and Refining:
The cleaned scrap is melted at controlled temperatures. Impurities and dross are skimmed off, producing refined zinc that meets industrial standards.
Alloying and Casting:
The molten zinc can be alloyed with other metals (e.g., copper, aluminium, magnesium) to form die-casting alloys or cast into ingots for resale.
Quality Control:
Every batch of recycled zinc undergoes spectrochemical analysis and purity testing, ensuring compliance with international quality benchmarks.
By focusing on efficient recovery and minimal waste, Sakthi Metals helps industries reduce their dependence on virgin zinc ore, lowering both cost and carbon footprint.
Recycled zinc is in high demand due to its versatility and performance in various industrial sectors. Major applications include:
Galvanizing Industry: Protects steel and iron from corrosion by coating with zinc.
Die-Casting Industry: Produces automotive parts, electrical components, and consumer goods.
Alloy Manufacturing: Used in the production of brass, bronze, and other zinc-based alloys.
Chemical Industry: For zinc oxide, zinc sulfate, and other compounds used in fertilizers and pharmaceuticals.
Building Materials: Roofing, gutters, and structural components benefit from zinc’s durability and resistance to corrosion.
Recycled zinc maintains the same properties as primary zinc, making it an ideal substitute that supports sustainable industrial development.
The global zinc scrap market has grown significantly with the push for sustainable resource management. Demand is driven by the construction, automotive, and galvanizing sectors, especially in Asia, where countries like India, China, and Vietnam are major consumers of secondary zinc.
Meanwhile, Europe, the Middle East, and North America serve as key suppliers of high-quality zinc scrap and dross.
