Founded in 1823, our company originally sold rice and various types of grain.
We began to specialize in the compost of biosolids in April 1977 and, we have since become proficient at producing fertilizer from organic human waste.
While chemical fertilizers have been extensively used around the world, the word “biosolids” is not well known among the general public.
Information about biosolids on television and the internet have been scarce. This could be due to the reduced popularity of recycled farming methods and organic farming, etc.

Process for fermenting sludge, animal and plant waste and other materials containing organic matter
In the beginning, there was no coverage in the media about industrial waste being converted to fertilizers.
At present, we invite locals and industrial waste organizations who produce organic waste to visit our treatment plant, explain the treatment method, and manufacture and process safe fertilizer.
We hope to contribute to everyone as an environmentally friendly company by providing safe organic fertilizer that it is a fully mature organic fertilizer, which does not affect the natural environment and cause crop damage.

Today, efforts to improve bioavailability and counter global warming are needed by society. As business in the environmental field is expected to expand in the future, we aim to grow as one of the leading companies in the industry to establish an unwavering position. It is our dream to shape the future to benefit everyone.
