Purpose of composting

Flow to compost organic wastes

Organic waste is waste derived from animals and plants. For example, livestock manure, solid waste produced from the manufacturing process of food such as vegetable residue, brewing residue, fermentation residue, waste of fish and animal. Organic fertilizer is produced from organic waste by microorganisms. They decompose easily decomposable organic matter.
To speed up the process artificially is called composting and it is necessary to create an environment where microorganisms are easy to operate.
In general, composting is decomposition by aerobic microorganisms and aerobic fermentation.

Conditions necessary for aerobic fermentation

Aerobic fermentation is carried out by the activity of aerobic microorganisms.It is important to create and maintain conditions that aerobic microorganisms can be active. Aerobic microorganisms need air to breathe.
Nutrient source for activity of microorganisms is necessary. Moisture is also important. But breathability gets worse if moisture is too high and even if the moisture is too low, growth of microorganisms is suppressed so appropriate moisture adjustment is also necessary. Microorganisms involved in composting are activated at an ambient temperature of 30 ° C or higher and temperatures of 60 ° C or more are necessary for killing or inactivating pathogens, parasite eggs or weed seeds.
It is also related to the evaporation of moisture so it is required to control the temperature.

What are the merits of using compost?

By properly using organic fertilizer, we can stably increase production of crop by supplying nutrients to plants, improving the chemical, material, biological of the soil and increasing soil productivity.
Compost is a kind fertilizer for both plants and soil.
Chemical fertilizers are excellent as fertilizer components, but microorganisms in the soil are killed as organic matter is not supplied. When soil cultivation to make crumb structure by microorganisms is stopped, soil productivity declines, the plants become weak against diseases and pests, and need to use fungicides and insecticides.

Representative composting process facility

For composting facilities, there are two general methods, “Stacking method” deposited in a compost shed and “agitation method” using a machine for stirring.
Since there are two types of stirring methods, open type and closed type, there are three kinds of composting process. Stacking method, Open type stirring method, and a closed type stirring method.
