Description

TECHNICAL FIELD [001] The following descriptive report for invention refers to the development of an organomineral fertilizer formulated to reduce odor emissions, through the use of gypsum to neutralize volatile ammonia compounds, charcoal for odor absorption, coating with PVA and charcoal for encapsulation and controlled release of the essence, in addition to natural essences for masking residual odors. BACKGROUND OF THE INVENTION [002] One of the main market problems of organomineral fertilizer is its characteristic odor, which, because it contains organic matter often originating from industrial waste, is strong and very unpleasant. [003] This problem causes retailers to avoid this product, as the strong odor spreads throughout the stock and the store, causing inconvenience to customers and employees. It is also avoided by customers, as they need to handle the product several times a day when fertilizing, and often have to store it on their properties. CURRENT PROBLEMS [004] To neutralize odors in organomineral fertilizers, various methods and additives are used. Some of the most common include: - Microorganisms: Certain microorganisms are added to decompose organic compounds that cause unpleasant odors; - Enzymes: Specific enzymes can be used to accelerate the decomposition of organic materials, reducing odor production; - Chemical additives: Substances such as iron and aluminum oxides can be added to form complexes that neutralize volatile compounds; and - Absorbent materials: Materials such as activated carbon or zeolites can be used to absorb and neutralize odors. [005] These techniques help make organomineral fertilizers more pleasant to handle and apply, as well as minimizing environmental impact. PROPOSED SOLUTION [006] Odor management in organomineral fertilizers is a significant challenge. Volatile ammonia compounds are the main contributors to undesirable odors. The addition of gypsum (CaSO₄<2H₂O) has proven effective in capturing and neutralizing ammonia. Additionally, the incorporation of charcoal and the use of PVA coatings are approaches to improve stability and reduce odors. High-temperature drying is an efficient practice for removing volatile compounds. DESCRIPTION [007] The characterization of the invention proposed in this report is achieved by describing the composition in question, necessary for carrying out the present application, in such a way that it can be reproduced in its entirety by appropriate technique, allowing full characterization of the functionality of the patent claimed. [008] Based on the description of the percentage quantities of the individual constituents that make up the product, the descriptive part of the report clarifies aspects that may have been implied, in order to clearly determine the protection now requested. [009] These quantities may vary, provided they do not deviate from what was initially required. COMPOSITION [010] Gypsum: Used to neutralize volatile ammonia compounds. Concentration: 4 ± 1% by mass of the final fertilizer composition. [011] Charcoal: Added for absorption of odorous compounds. Concentration: 3 ± 1% by mass of the final fertilizer composition. [012] Coating with PVA and Charcoal: PVA (Polyvinyl Alcohol): Provides encapsulation of active compounds, controlling nutrient release and odor emission. Concentration: 0.002 ± 0.001% by mass of the final fertilizer composition. [013] Charcoal: Incorporated into the coating to improve odor absorption capacity. Concentration: 0.025 ± 0.015% by mass of the final fertilizer composition. [014] Natural Essences: Natural plant essences, such as eucalyptus oil, peppermint oil, lavender oil, and jaboticaba essence, are added to mask residual odors. Concentration: 0.000375 ± 0.0001% by mass of the final fertilizer composition. PRODUCTION PROCESS [015] Mixing of Components: The gypsum and charcoal are mixed with the other components of the organomineral fertilizer until a homogeneous distribution is obtained. [016] Shaping: The fertilizer is granulated or pelletized according to conventional shaping methods. [017] Addition of PVA: The mixture is then coated with a PVA solution by spraying in a rotating drum with the addition of powdered charcoal. [018] Drying: The coated material is dried at a temperature between 350°C and 400°C to form encapsulated granules and remove volatile compounds. [019] Sieving: Granules of the desired diameter are separated from the other particle sizes. [020] Addition of Natural Essences: The granules are sprayed with natural essences in a rotating drum. ADVANTAGES OF THE INVENTION [021] Odor Reduction: The combination of plaster and charcoal significantly reduces odors. [022] Controlled Release: The PVA coating controls the release of nutrients and odorous compounds. [023] Odor Masking: Natural essences provide a pleasant fragrance, masking any residual odor. [024] Removal of Volatiles: Drying at high temperatures removes volatile compounds, improving product stability. [025]
