Founded in 1894, we at Tanaka Sekkai Kogyo have mined high quality lime, producing and developing lime and lime products in Kochi Prefecture for over 120 years. We have contributed to the expansion of our local economy through the production and development of various raw materials. From the 1950s, we mined and distributed serpentinite (a raw material which is found in abundance in Kochi Prefecture) to blast furnace steel makers for over 50 years.
Using our years of experience and knowledge as a raw materials producer and distributor, we set out to use our expertise in the field of waste management. In the 1960s, we started with the collection, transport and intermediate processing of various types of waste.
As a company involved in the distribution of mined natural resources, environmental conservation is our main priority. We are taking the necessary steps to become a resource-recycling corporation through better communication in our community and through our continued efforts in raising environmental awareness among our employees.
In this day and age, the need for a society which is sustainable, recycles resources, and has low impact on the environment is being challenged on a global scale. At Tanaka Sekkai Kogyo, we are expanding our vision beyond Japan, taking into consideration both the effective use and recycling of resources in order to lead the way to a sustainable future.
For the past 120 years, the foundational pillars of Tanaka Sekkai Kogyo have been the effective use of resources, contributions to the community, and the research, development, and creation of various products and services for the progression of the economy.
Such principles continue to force us to reevaluate our role in the community. With our current community contributions in employment of the disabled, environmental education and community cleaning projects, we hope to continue our efforts in the recycling and reuse of natural resources as members of society.
