Since 2013 the global provider of synthetic iron oxide and chrome oxide pigments has been building its new manufacturing site with the objective of an expansion to 150,000 metric tons per annum. Using the most modern technology, the Hong Kong-based company will produce yellow, red and black iron oxide pigments in Tongling, Anhui Province. Taking responsibility for the environment, the plant utilises fully integrated waste stream recycling. Cathay has invested in the joint venture plant with Tonghua Group as Rely Science & Technology Co., Ltd.

At a site of 200 hectares, Cathay’s operations has production equipment located in over ten different buildings. From here the company provides the raw pigments, which receive their finishing treatment for various application areas in its plant in Yixing (Jiangsu Province). The finished pigments are used in the coloration of cement-based building products, coating systems, polymers, papers, cosmetics, pharmaceutical and other specialised applications. In the course of 2014, the initial construction phase for the pigment production and the manufacturing test phase have been completed successfully. The initial capacity of 60,000 metric tons per annum is on stream with immediate effect. Once fully completed, the plant will boost the total manufacturing capacity of Cathay Industries Group to over 200,000 metric tons yearly.

Pigment granulation

Cathay is currently erecting spray driers for the production of pigment granules at the same location. The capacity for these so-called microgranules will initially be 20,000 metric tons per year and will be commissioned at the end of the year 2014. Further expansion will be realised after the year 2015.

Optimising energy use

As the factory will be running the Penniman Process, state-of-the-art production is ensured by implementing environmentally friendly operations including integrated waste recycling. This process optimises the energy use and works with lower carbon emissions. "The pigments we are going to produce in Tongling will be in line with the high product quality of Cathay Industries and at the same time reduce emissions to the environment to the lowest level ever seen in the history of iron oxide manufacturing in China.

In consideration of the ecological and economical strategy Cathay cooperates with Tonghua Group. The chemical supplier of pyrite, sulphur ore, sulphuric acid, fertiliser, phthalic anhydride and titanium dioxide also contributes to the production of di-ammonium phosphate and of calcium.
