Recycled Silica Sand
High-silica content, rounded grain shape for improved permeability and reduced binder usage, with low thermal expansion to minimise casting cracks.
Turning waste into high-value green resources
Recycled Foundry Sand and Refractory Materials for Precision Casting
Leelink supplies BSI-verified recycled silica and mullite sand to casting operations in the EU and US, cutting material costs and scope-3 emissions at the same time.

Products and Materials
Recycled Mullite Sand
High-alumina recycled material delivering excellent refractoriness and thermal stability; no calcination required, resulting in ultra-low carbon emissions.
Recycled Refractory Castable
Unshaped refractory formulated with more than 70% recycled content, designed for furnaces and ladles handling molten iron; easy to cast and apply.
Recycled Plastic Refractory
Unshaped recycled refractory with a workable, plastic consistency suited for lining high-temperature process equipment.
Recycled Fire Mortar
Unshaped recycled refractory mortar formulated for high-temperature bonding applications in furnace construction and repair.
Why Source From Leelink
BSI-Verified Carbon Credentials
Leelink's carbon footprint figures are independently verified by BSI, giving procurement teams in regulated markets a defensible data point for scope-3 reporting rather than a supplier self-declaration.
Dual ISO Environmental and Quality Cover
ISO 9001 and ISO 14001 certification means quality management and environmental performance are audited together, reducing the due-diligence burden for importers and OEM customers.
TAF-Accredited In-House Laboratory
Physical and chemical properties are tested in a TAF-accredited laboratory, so specification sheets reflect verified material performance rather than nominal targets.
Circular Feedstock, Consistent Supply
Leelink draws feedstock from spent foundry sand, waste glass, and used refractory bricks, converting industrial waste streams into a repeatable supply of high-grade recycled materials.
Active Export Track Record
Materials are already shipped to buyers in Germany, Italy, the United States, Japan, and Vietnam, confirming compliance documentation, logistics capability, and familiarity with import requirements across multiple jurisdictions.
