The Company That Changed the Fate of Oil: Daiseki and the Boom in the Recycling Business, 1958–2000

Founded in 1958, Daiseki expanded its business from the manufacture of lubricating oils to the recycling of waste oil. In 1972, the company obtained a license for industrial waste disposal in Nagoya City and began shifting its focus away from simply disposing of waste oil and sludge toward utilizing them as recycled fuel and resources. In 1995, the company began trading its shares over-the-counter, and in August 1999, it was listed on the Second Section of both the Tokyo Stock Exchange and the Nagoya Stock Exchange. An environmental business report from that time noted that it was the first listing by an industrial waste intermediate treatment operator and reported that the environmental division constituted the core of the company’s business. Amid growing concerns over a shortage of final disposal sites, the company identified waste volume reduction and resource recovery as growth areas and was preparing to embark on environmental analysis—such as soil contamination surveys—as well as research and development of new treatment technologies. This approach—viewing waste not as a burden but as a resource—is a prime example of how environmental measures and corporate growth can be effectively linked.
