  • Fermentation of organic fertilizer and matters needing attention

    Fermentation of organic fertilizer The aerobic fermentation process is adopted for the fermentation of organic fertilizer raw materials, and the windrow turner is adopted. The fertilizer equipment has the mixing function and can be used as a mixer. When batching, the materials laid in layers can be stirred evenly and then enter the fermentation ...

  • How many days does it take to ferment organic fertilizer

    Most domestic organic fertilizer products can only be composted and fermented for 7-10 days, and such products can only reach the harmless standard. The fermentation process of high quality organic compost usually takes 45-60 days. This is because in the early stage of heating and high temperature of the organic ...

  • Development of time-temperature probes for tracking pathogen inactivation during composting

    Pathogen inactivation is expected to occur in compost if temperatures over 55°C (131°F) are maintained for at least 3 days, or 15 days in windrows. However, a literature review revealed pathogen survival in a significant number of processes appearing to meet the prescribed time-temperature criteria. It was hypothesized that pathogen survival may be due to the existence of undetected temperature ...

  • Influence of temperature during the initial phase of Composting on biological activity and emission of Ammonia and dinitrogen oxide

    Composting is a robust and cheap biological treatment method useful for all solid biodegradable waste. The performance of composting can vary substantially depending on managing conditions such as oxygen supply and compost temperature. Oxygen and temperature affects the rate of degradation and may also influence emission of NH3 and N2O. The gaseous N losses during composting from organic ...

  • Potential pollutants from farm, food and yard waste composts at differing ages: Part I. physical and chemical properties

    There is little information about the changes in physical and chemical properties of compost as a function of compost feedstocks and age of the compost mixture. As a consequence of this gap, the potential of compost to serve as a pollutant source relative to compost age (from initial mixing of raw feedstocks to mature compost) and feedstocks (i.e. % of food, manure, bedding, leaves, etc.) during ...

  • Biocontained mortality compost using liquid manure

    During disease outbreaks, composting has been used to safely dispose of carcasses and infectious solid manure. However, optimized methods have not been established to use liquid manure (> 80% water content, WC) from dairies as the substrate for mortality composting. In April of 2007, a 3x2 factorial study was conducted in wooden compost bins (240 x 240 x 140 cm) lined with 0.5 mm plastic to a ...

  • Design, testing and implementation of a large-scale urban dog waste composting program

    In Montreal, Québec, many dogs are exercised in fenced-in runs in parks. Consequently, these dog parks are a high-density source of large amounts of dog waste, which is typically collected by the owner in a plastic bag and deposited in the municipal garbage. In 2004, an experimental large-scale dog waste composting programme was initiated at the Notre-Dame-de-Grâce (NDG) dog run in Montreal, ...

  • How to Make Organic Fertilizer by Feces Composting

    Fecal composting organic fertilizer manufacturing process is to adjust the carbon-nitrogen ratio in the manure of the livestock and poultry by turning machine, manually controlling the conditions of water, temperature, pH and the like, and treating the manure of the livestock and poultry by the fermentation of the microorganisms to produce organic fertilizer.   I. Major ...

  • Key technology of composting of biofertilizer

    It mainly includes the composition of raw materials, the selection and use of microbial agents and the technical control of aeration and aeration in the fermentation process. ① the raw material consists of livestock manure, sawdust, crop straw and other raw materials, which are mixed to adjust the carbon nitrogen ratio. In addition, calcium phosphate, zeolite, raw soil and other substances are ...

  • Modeling composting kinetics: A review of approaches

    Composting kinetics modeling is necessary to design and operate composting facilities that comply with strict market demands and tight environmental legislation. Current composting kinetics modeling can be characterized as inductive, i.e. the data are the starting point of the modeling process and determine the type of model used. It is argued that the inductive empirical approach has been ...

  • Design and performance of a simulated feedstock for composting experiments

    This paper reviews the composition and performance of simulated feedstock mixtures previously employed in composting research, and presents a new simulated feedstock. The new feedstock was prepared using readily available dry ingredients - ostrich feed pellets, office paper, finished compost and woodchips - representing the substrate, amendment, seed, and bulking agent components of a composting ...

  • Using crop straw to process bio organic fertilizer

    Crop straw is a by-product of crop harvest, which contains a lot of organic matter, nitrogen, phosphorus, potassium, trace elements, etc. it is one of the important organic resources in agricultural production. The process of straw fermentation and decomposition is a process dominated by microbial activities. In order to make high-quality organic fertilizer by using ...

  • Leaf composting in cold climates: a theoretical and an experimental evaluation

    There are many factors influencing the process of composting organic waste. This paper provides an experimental and theoretical evaluation of the leaf composting process to elucidate the importance of these various factors during composting of leaves. The analysis is performed specifically for the environmental conditions encountered in cold climates. Theoretical models are developed to evaluate ...

  • Composting of vegetable waste in subtropical climates

    This experiment examined the possibility of using composting as a method of waste disposal in subtropical countries, such as the United Arab Emirates (UAE), where temperatures are high and humidity is low. In order to simulate conditions in the UAE, a representative mixture of wastes generated in the UAE was prepared and tested at ambient temperatures resembling those of subtropical countries. ...

  • The wonder of red wiggler worms

    Worms are going to play an ever-increasing role in waste management and soil production. Red wiggler worms convert food scraps and paper into nature's finest fertilizer. As nature's original recyclers, they consume approximately half their weight daily!Many municipalities have introduced organic collection programs, and backyard composting is widespread. Vermicomposting is a great alternative for ...

  • Vermicomposting of solid textile mill sludge spiked with cow dung and horse dung: a pilot-scale study

    This paper reports the vermicomposting of Solid Textile Mill Sludge (STMS) spiked with Cow Dung (CD) and Horse Dung (HD) in a six-month pilot-scale experiment employing Eisenia foetida. Growth and fecundity of Eisenia foetida were significantly affected by temperature variations. The lesser number of cocoons and hatchlings were produced in pilot scale experiments than in controlled temperature ...

  • Influence of environmental parameters on the composting kinetic of lignocellulosic residues

    The kinetic of the thermophilic composting process of trimming residues was studied under several parameters [moisture (40-70%), aeration (0.2-0.6 l air/kg min) and particle size (1-5 cm)] in order to determine the best composting conditions to ensure an optimum composting design. Under those conditions, suitable temperature evolutions have been found for all the reactors. The kinetic model ...
