Resources are not for single use
Elevating materials into a circular-value economy

Ying Chang was founded to advance material reuse and the circular economy in Taiwan's industries.
 

Through chemical engineering processes, we convert sulfuric acid used in semiconductor manufacturing, together with other elements, into high-purity compounds for use as premium industrial raw materials.

In addition to recycled and regenerated raw materials, we also produce a range of chemical raw materials. Our products include:

  • Sodium thiosulfate (Na2S2O3)
  • Ammonium sulfate ((NH4)2SO4)
  • Magnesium sulfate heptahydrate (MgSO4·7H2O)
  • Anhydrous magnesium sulfate (MgSO₄)
  • Copper powder
  • Poly aluminium chloride (PAC)
  • Regenerated sulfuric acid (H2SO4)
