Kobe City, Mitsubishi Corporation Agri-Service and Swing completed a two-year demonstration test of the Nutrient Removal and Resource Recycling (Phosphorus)/Innovative Technology Demonstration Project - KOBE Harvest Project- at the Higashinada Treatment Plant in Kobe City, which was adopted as a B-DASH project by the Ministry of Land, Infrastructure, Transport and Tourism in FY2012.
This project was initiated with the aim of "purifying and recovering phosphorus with high purity from digested sewage sludge and returning it to agricultural land as fertilizer."
After the demonstration test, the registration of fertilizer by the Ministry of Agriculture, Forestry and Fisheries was completed in 2014, and the recovered phosphorus was named "Kobe recycled phosphorus" and returned to agricultural land as "fertilizer."

Development of recycled phosphorus blended fertilizer, "Kobe Harvest"

"Kobe Harvest 10-6-6-2", a recycled phosphorus blended fertilizer, was developed with hearing the opinions of JA Hyogo Rokko, Japan Agricultural Cooperatives, and local farmers based on the considering that the development of suitable fertilizer for the location of KOBE is necessary to promote dissemination of recycled phosphorus.
After one year of experimental cultivation, it began trial marketing in December 2015.
The sales has been gradually expanding and the vegetables cultivated with "Kobe Harvest" are now being used for school lunches in Kobe City.
Every summer, we provide an opportunity of a sweet corn harvest experience.
It is also useful for dietary and environmental education.

"The phosphorus recovered at the sewage treatment plant changes to blended fertilizer, returns to agricultural land and becomes a new agricultural crop. It lines up at the table, goes back to the sewage treatment plant through human body, “the story that was originally envisioned, now steadily spreading as "circle of resource recycling" in Kobe.
We will continue to contribute to the local consumption of recycled phosphorus resources.
