NIKKO has developed a technology to recycle bone china into fertilizer and has been certified by the Ministry of Agriculture, Forestry and Fisheries of Japan on February 10, 2022.

NIKKO aims to create a circular economy around food together with restaurants, farm producers, citizens, and more.

First problem is that there were no choice but to dispose of used and broken ceramics. The three elements of fertilizer, was largely imported from overseas, and fertilizer prices were rising due to soaring import prices.

Recycle discarded fine bone china into a fertilizer called “BONEARTH”

NIKKO FINE BONE CHINA recycled into fertilizer called “BONEARTH.” It is calcinated in high temperatures, making it a scent free, storable, safe, and clean phosphoric acid fertilizer. 

BONEARTH's phosphoric acid is melted by the citric acid emitted naturally by plants, then absorbed as a nutrient. It will not hinder the plant’s growth when too much fertilizer is added. It doesn't melt in water, meaning effective for a long time, and prevents it from running into rivers.
