Zinc Materials and Eco Management


Company Profile:

Padaeng Industry Plc (PDI) is the leading producer in Southeast Asia of special high grade zinc metal and zinc based alloys serving mainly the Thai automotive and construction industry.  Founded April 10th, 1981 PDI was listed on the Stock Exchange of Thailand July 21st, 1987. Its current registered capital reaches Baht 2.26 billion.

From 1984 to 1995, PDI entirely relied on zinc ore supplies from its own Mae Sod mine in the Tak province. In 1995, PDI started to import zinc ores from overseas as a main feed for its Tak refinery. These imported raw materials are transformed into calcine at PDI’s roaster in Rayong prior to being shipped to the Tak refinery. In 2008, PDI added the use of recyclable raw materials in combination with mined ores as part of its CSR vision to become more eco-friendly and to support its corporate strategy to optimize operational costs.

In 2014, PDI is expanding and diversifying into 3 business-units:

  • PDI Materials producing and selling various metal based added value materials
  • PDI Eco operating recycling and waste management business
  • PDI Energy operating renewable energy plants
