Japan’s Taki Chemical said it would invest approximately $20-mn (¥3-bn) to expand production facilities for its ultra-high basicity poly-aluminium chloride product, PAC700A, at its headquarters plant in Kakogawa City, Hyogo Prefecture, with completion scheduled for July 2028.
‘PAC700A’ is an environmentally friendly water treatment agent offering higher coagulation performance than conventional products, the company said, adding that it reduced costs by lowering the amount of chemicals used and sludge generated, while helping address the deterioration of raw water quality caused by climate change and supporting stable operation of water treatment facilities. Sales volume has been rising steadily on the back of these performance characteristics, it said.
The expansion will raise PAC700A production capacity at the plant by approximately 40,000 tonnes a year, effectively doubling current output, primarily to meet rising demand in the Kinki, Chugoku-Shikoku and Tokai regions, Taki Chemical said. The additional volume is equivalent to about 7% of Japan’s domestic PAC market, estimated at approximately 590,000 tonnes a year.
The company, which has more than half a century of experience in the water treatment chemicals business, currently holds a market share of over 30% in Japan’s domestic PAC market, it said. Along with a completed capacity expansion at its Chiba plant and an ongoing expansion at its Kyushu plant, the headquarters plant project forms part of a broader effort to strengthen nationwide supply capacity, with the company aiming to achieve a 50% domestic market share at an early stage.
