Overview
Tsukishima Kankyo Engineering Ltd. is a Japanese environmental engineering company headquartered in Harumi, Chuo-ku, Tokyo. It designs, manufactures and installs pollution-control and resource-recovery equipment, with core strengths in waste liquid and wastewater treatment, waste gas treatment, solid waste treatment and tower packing. Its corporate philosophy is to contribute to the preservation of the global environment through its environmental technologies, and it positions itself as a specialist engineering house capable of custom, one-off designs for a wide range of industries. The company traces its origins to 1958, when Tsukuda Setsubi Sekkei Jimusho (Tsukuda Equipment Design Office) was established with capital of 2.5 million yen, focused on the design, fabrication and construction of chemical-industry unit-operation equipment such as distillation, absorption, adsorption, drying and extraction. It was renamed Yahata Kakoki Co., Ltd. in 1960 after investment from Yawata Iron & Steel and Yawata Chemical Industry, and later became Nittetsu Kakoki Co., Ltd. in 1970 following the creation of Nippon Steel. In 2005, Nippon Steel Group transferred its shares to Tsukishima Kikai Co., Ltd., bringing the company into the Tsukishima group, and it was renamed Tsukishima Nittetsu Kakoki Co., Ltd. In 2006 it adopted its current name, Tsukishima Kankyo Engineering Co., Ltd. Its product portfolio includes submerged-combustion waste liquid incinerators, hydrochloric acid recovery systems, CFC destruction equipment, wastewater treatment systems, solid incineration technology, VOC groundwater purification equipment, and tower packing. The company states that it has established a top-class domestic and international position in the share of submerged-combustion waste liquid incinerators, hydrochloric acid recovery units and CFC destruction equipment, and has more recently expanded into wastewater treatment and solid incineration fields. Tsukishima Kankyo Engineering serves industries including petrochemicals, steel and metals, paper and inorganic chemicals, bio/medical/food, semiconductors and LCDs, and industrial waste treatment. It is a member of the Tsukishima Holdings Group, alongside Tsukishima Kikai, Tsukishima JFE Aqua Solution, and overseas affiliates such as TSK Engineering (Thailand), TSK Engineering (Taiwan) and Tsukishima Engineering (Malaysia). The company continues to pursue sustainability and a circular economy through its environmental preservation technologies.
History
The company was established in April 1958 as Tsukuda Setsubi Sekkei Jimusho (Tsukuda Equipment Design Office) with capital of 2.5 million yen. Its business was the design, fabrication and construction of equipment based on unit operations in the chemical industry, such as distillation, absorption, adsorption, drying and extraction. In July 1960, with investment from Yawata Iron & Steel and Yawata Chemical Industry, it entered their corporate group and changed its name to Yahata Kakoki Co., Ltd., increasing capital to 20 million yen. Capital was raised to 80 million yen in May 1962, and a Kyushu sales office was opened in October 1962. In March 1966 the company exported solvent recovery technology to Thermal Research of the United States. In June 1967 it entered a technical tie-up with Dr. Teller of the United States and added tower packing to its product lines; a test plant (Itabashi Research Laboratory) was opened in December 1967. In June 1970, following the creation of Nippon Steel Corporation, the company changed its name to Nittetsu Kakoki Co., Ltd. In January 1972 it entered a technical tie-up with Chemical Construction Corporation (Chemico) of the United States, exporting technology for organic chloride waste liquid incineration and acid-pickling waste liquid treatment and hydrochloric acid recovery, and importing sulfuric acid concentration and recovery technology. In May 1972 it tied up with Akzo Engineering of the Netherlands for organic waste liquid incineration technology, and in February 1973 with Henry Balfour of the United Kingdom for organic waste liquid incineration and acidic waste liquid recovery technology. In April 1973 its submerged-combustion waste liquid treatment process won the Petroleum Institute's Technology Progress Award, and in February 1975 its process for incinerating high-concentration organic waste liquid and recovering valuables won the Society of Synthetic Organic Chemistry's Environment Award. In October 1975 it introduced non-catalytic dry denitration technology from Mitsubishi Chemical. Capital was increased to 113.12 million yen in June 1976. In May 1977 it established NCE Corporation USA as a wholly owned subsidiary (closed in December 1980). In August 1977 it tied up with Silicone of the United Kingdom for organic chloride incineration and hydrochloric acid recovery technology, and in December 1978 introduced LNG vaporizer technology from John Thurley of the United Kingdom. In July 1981 its heat-medium exhaust heat recovery system for blast furnace hot stoves won the Japan Machinery Federation's Excellent Energy-Saving Equipment Award, and in March 1982 it received the Clean Japan Center Chairman's Award as a recycling-contributing company. In November 1982 the head office moved to Minato-ku. In June 1990 its high-temperature thermal decomposition treatment system for liquid waste PCB won the Japan Society of Industrial Machinery Manufacturers' Excellent Pollution Prevention Equipment Award. In April 1991 it established Nittetsu Kakoki Kyushu Co., Ltd. as a wholly owned subsidiary with capital of 10 million yen, and in November 1991 its low-temperature desorption solvent recovery system won the Japan Adsorption Society's Technology Award. In December 1991 it acquired the land and building of its research laboratory, and in April 1992 capital was increased to 455 million yen. A new laboratory building was completed in February 1993. In May 1993 its high-concentration hydrochloric acid recovery technology won the Separation Technology Society's Separation Technology Award, and in June 1993 its vertical airflow incinerator won the Japan Society of Industrial Machinery Manufacturers' Excellent Pollution Prevention Equipment Award (Director-General of the Agency of Industrial Science and Technology Prize). In September 1997 a new head office building was completed and the registered head office moved to Itabashi-ku. In November 2004 it absorbed Nittetsu Kakoki Kyushu Co., Ltd. In April 2005, following the transfer of shares from the Nippon Steel Group to Tsukishima Kikai Co., Ltd., it entered the Tsukishima group and changed its name to Tsukishima Nittetsu Kakoki Co., Ltd. In September 2005 it won the Minister of Economy, Trade and Industry Prize at the 8th Ozone Layer Protection and Global Warming Prevention Awards, and in October 2005 it received the Encouragement Award at the Clean Japan Center's FY2005 Resource Circulation Technology and System Awards. In April 2006 it changed its name to Tsukishima Kankyo Engineering Co., Ltd. In August 2006 its CFC destruction equipment won the 17th Separation Technology Society Technology Award, and in November 2006 the registered head office moved to Chuo-ku, Tokyo, with the Development Research Department relocated to the Tsukishima Kikai research laboratory. In June 2007 its groundwater pumping VOC purification equipment won the 33rd Excellent Environmental Equipment Awards (Japan Society of Industrial Machinery Manufacturers Chairman's Award).
