Overview of the project to convert chicken manure into fertilizer in Mima County, Tokushima Prefecture
Mima-gun, Tokushima Prefecture, is one of the largest poultry farming areas in Japan, producing approximately 140,000 tons of chicken manure annually. 1994, a third-sector chicken manure composting project was launched in Mima-gun with the cooperation of poultry farming-related organizations and local businesses. The project was subsidized by Tokushima Prefecture and the national government, and the total project cost amounted to approximately 1.55 billion yen. Currently, there are 10 compost centers in Mima County, producing approximately 23,000 tons of compost annually and contributing to organic farming locally and nationwide.
In addition, Maruzen Oil & Chemical Trading (Tokyo) manufactures "Bio-Turf," a soil conditioner made by adding humic acid and microorganisms to chicken manure, and supplies 1,200 tons per year to golf courses and public facilities. This improver improves soil aeration and nutrient availability, and demand for this product is increasing. As the project progresses, odor control and water quality preservation technologies have also improved, making Mima County an advanced regional model for promoting environmental preservation and resource recycling.
