Composting: Art and science of organic waste conversion to a valuable soil resource
Raw organic materials such as grass clippings and manure are transformed into stable soil-like humic compounds through decomposition in the composting process. Composting is an age-old practice found in various settings, ranging from domestic to industrial. Compost maker machine is becoming an increasingly practical method of organic waste disposal when landfills reach capacity ...

Basic process of manure fertilizer production from farm manure
The composting method of organic manure production is a process of mineral, humic and harmless degradation of organic matter in solid manure by microorganism under the condition of artificial control of water, carbon nitrogen ratio and ventilation. Composting is mainly divided into aerobic composting and anaerobic composting, which is mainly aerobic composting at present. Composting manure ...

What treatment and equipment are needed to produce organic fertilizer?
Process flow of organic fertilizer production line: 1. Fermentation Fermentation is the first step in the production of organic fertilizer regardless of its configuration. The manure is collected and mixed with hay and rotten silage to make compost and let it ferment. In the process of fermentation, compost turning machine is used to make the manure fully ferment. Modern aerobic composting is a ...

Organic fertilizer production technology - aerobic composting technology
Aerobic composting technology is an important technical means for the disposal of organic waste, especially suitable for the realization of fertilizer and substrate of agricultural solid waste. For industrialized processing of organic fertilizer, compost turning machine is usually used to ensure the smooth progress of aerobic fermentation. Aerobic composting is the absorption, oxidation, and ...

Organic fertilizer turner is the core of aerobic composting
As the core equipment of aerobic dynamic composting, the organic fertilizer turning machine develops rapidly in the fertilizer equipment family. Fermentation compost turner is a kind of agricultural machine, instead of traditional tools such as manual, forklift and so on. It is the mainstream product that affects the development trend of compost industry. The importance of the organic fertilizer ...

Cow manure organic fertilizer production line process
The cow manure organic fertilizer production line is a complete set of equipment for processing organic fertilizers with cow dung as raw material. The cow manure organic fertilizer manufacturing process uses crops such as straw and rice bran as fillers, and then sprinkle the biological strains through the turner. It is turned over once every 1-2 days. It can be completely decomposed in 7-10 days ...

ANFIS approach to the working of a compost–heat extractor
Composting is an organic sludge management option in which volatile solids are converted to carbon dioxide and water. As the sugar cane press mud undergoes aerobic composting, the bed heats–up to a temperature in the range of 50–70°C, releasing thermal energy and the heat liberated was extracted using a heat pipe. A neural network approach is applied to analyse the data obtained ...

Effect of feeding efficient microbial community on aerobic composting of municipal waste and excrement
Each of the total 13 strains of bacteria was isolated based on the characteristics of municipal waste and excrement, which include 6 strains of bacterium, 4 strains of streptomyces and 3 strains of actinomycetes; all of these were appropriate for aerobic composting. The Efficient Microbial Community (EMC) was constructed by these strains combination at certain ratios. A series of experiments were ...

Odour pollution problems caused by composting activities in flanders: current situation and abatement strategies
In Flanders, garden fruit and vegetable (GFV) waste is selectively collected and composted in 7 composting plants, in six of which aerobic indoor composting is used. In the seventh plant waste is anaerobically digested first followed by an aerobic post-treatment. The total amount of waste composted was about 275 000 tons in 1997 (OVAM, 1999). The nominal capacity of the composting plants varies ...

Composting in flanders: the vlaco experience
Currently, the Flanders waste policy is based on the so-called ‘ladder of Lansink’. Six aerobic composting and one anaerobic digestion plant are operational for the treatment of biowaste. Some new composting plants are foreseen for 1999 and/or 2000. Composting retention time varies from 10 to 15 weeks. Green waste is treated in 15 open air composting plants. With respect to the use of compost ...

Introduction of composted digestates in agriculture
Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to the ...

Effects of the anaerobic biowaste treatment processes Management on the digestate quality (residues from Digestion/compost, process water/wastewater)
Regarding the municipally-collected biowaste amount in Germany, a quantity of 90 - 100 kg/ per annum per citizen is registered (Gallenkemper and Doedens, 1994). That results in an annual biowaste amount of 6.3 to 7 million tons in the Federal Republic of Germany (FRG), whereby also sewage sludges and biogenic, industrial wastes are added. According to Hochrein (1994) about 3 million tons of ...

Composting
Introduction Composting is a controlled biological process by which organic contaminants (e.g., PAHs) are converted by microorganisms (under aerobic and anaerobic conditions) to innocuous, stabilized byproducts. Typically, thermophilic conditions (54 to 65 °C) must be maintained to properly compost soil contaminated with hazardous organic contaminants. The increased temperatures result from heat ...

Stability measurement of Biosolids Compost by Aerobic Respirometry
Oxygen uptake of biosolids compost was measured during both laboratory and full-scale studies. Aerobic respirometry of solid samples of compost provided a precise measure of microbial activity. There was a noticeable decreasing trend in oxygen consumption over 25 days of composting, thereby indicating increasing stability. Moisture content also was found to affect the compost stability. During ...
