Founded over 100 years ago, Tanaka Sekkai Kogyo's core business activities have been in the production and sales of quicklime and slaked lime, which are found in high concentrations in Kochi Prefecture.
With a core focus on the production of sub-materials for blast furnace steel production, we offer a wide array of minerals from mines in Japan and overseas.
We focus on the collection, transport, and intermediate processing of household and industrial waste, including plastic and packaging material recycling.
We are an intermediate processing center for concrete waste, construction sludge, and excavated soil from construction and demolition sites.
We utilize post-mining sites for mega solar panels to create reusable energy.
