| Outline of Final Research Achievements |
Ten percent of the phosphorus in the digestive fluid was found as fine deposits -- as 10μm-long bars of calcium phosphate -- in the methane-fermentation digestive fluid created from food waste.
As a result of the trial to separate calcium phosphate using a homemade flotation device, calcium phosphate was collected as a matter which contains impurities after adding a surfactant. By removing fine deposits from the digestive fluid, it will become easier to spray it as a liquid fertilizer. Effective use of ninety percent of the Phosphorus in the solution can be expected.
