WEAK ALKALINE ORGANIC FERTILIZER FROM ORGANIC WASTE INCLUDING FOOD WASTE AND ITS MANUFACTURING METHOD

摘要

Disclosed is a calcium-enriched organic fertilizer for acid soil and/or a magnesium-enriched organic fertilizer for field products and/or a silica- enriched organic fertilizer for paddy field products, and its manufacturing method, which method includes elimination saline matters harmful to the soil and plants/animals from organ ic waste including food waste, adding quick lime and/or dolomite for hydration, and introducing a drying exhaust gas having a high CO2 content generated from the factory, an exhaust gas fro m a lime calcining kiln, or an out sourced CO2 gas into heretically sealed mixer, aging tank an d hydration tank in the reverse order to cause a carbonation reaction between CO2 and the dissociated ions of the additives and thereby make the organic waste in a weak alkaline state, and adding a siliceous material. Alternatively, a customized organic fertilizer suitable for the ingredients of a specific soil and a soil conditioner can be prepared by adding carbon resources, zeolite, bentonite, clay minerals, moisture regulator, or organic materials to those organic fertilizers. The present invention is also directed to a functional organic plant nutriment for high- value garden plants or lawn in golf links and its manufacturing method, which includes further addi ng a functionality provider prepared from chitosan to enhance the plants' absorption of nutriments and metal ions, reduce the calcium deficient of the plants caused by acid rain and increase the plants' resistance and strength. Furthermore, the present invention is directed to a method for sanitary treatment and enhancement of hydration in which the reactor tank, the aging tank and t he mixer are hermetically sealed in the manufacture of the organic fertilizers to provide a condition, of high temperature and high pressure like a pressure cooker through internal exothermic reaction and volume expansion and thereby destroy disease-causing bacteria and insect egg s under strong alkalinity caused by the dissociation of lime contained in the additives; a method for eliminating the damages of products and olfactory offensiveness caused by harmful gas through chemical deodorization using a reaction between calcium ions and malodorous substance s (e.g., nitrogen and sulfur compounds) and physical deodorization using a deodorizer; and a method for manufacturing a neutralizer for acidic waste as a byproduct by condensing th e vapor and exhaust gas generated in the CO2 gas introducing process. [110] In conclusion, the present invention enables to utilize environmental contamination-causing organic waste including food waste as a weakalkaline fertilizer in an economical way and apply the organic fertilizer on a large scale as compost, thereby contributing to environmental improvement and organic farming and establishi ng a system for converting the organic waste into the products of the nature circulation./S DOAB
