Seeking Technology Partners for Shipyard Waste (Copper Slag)

Background / Description

The technology seeker is a Singapore company with strong presence in the marine and offshore industry. The company has direct access to constant supply of spent copper slag, a waste product from blasting activities in the shipyards. They have an existing process to recycle spent grit into washed copper slag to be used as sand replacement in ready-mixed concrete for the construction industry. The shipyard industry in Singapore as a whole produces about 300,000 MT of used copper slag annually, or more depending on activities.

Copper slag is a by-product generated from the production of the copper metal. Copper slag is commonly used as an abrasive grit for blast cleaning operations in shipyards. After blasting, the used copper slag can no longer be used for blasting and instead is recycled by sieving and washing into washed copper slag, which is then used as sand replacement in ready-mixed concrete. Iron oxide and silicon oxide are the two main components in copper slag, making up approximately 75% or more of the material. Other main compositions of the material are calcium oxide, aluminium oxide and magnesium oxide.

The company sees the potential for this waste product to be used in higher value applications that are suitable for implementation in Singapore. The company is seeking technology provider or collaborators to provide capabilities and technologies in developing applications or use cases for used or washed copper slag.

Technical Specifications
