The process of waste treatment into compost fertilizer:

Step 1: Classification of garbage

Compost quality depends on the quality of initial waste. Therefore, waste classification plays an important role.

Step 2: Mix garbage with additional ingredients

Carbon and nitrogen ratio are important for waste decomposition. Both carbon and nitrogen are foods for microorganisms to decompose into organic fertilizers. In which carbon is important for the growth of cells, and nitrogen is a source of nutrients.

The original material has a ratio of C/N from 25: 1 to 40: 1 to help the process of decomposition quickly and effectively. The c/n oscillation of the family garbage is quite high and can be composted.

Step 3: Put garbage in the incubation system (incubation according to beds)

Organic waste component easily decomposed will be spread on the surface of the bed with a thickness of about 50cm and provided by biological products on the surface of the garbage in the bed. In the first few days the temperature will increase to 600 oC, this helps the compost feces have no pathogens and weeds. The incubation process will take place for 30 days and then will be taken through the tank to cook for another 9 days. During the incubation process, the temperature must be monitored on a regular basis.

Step 4: Stir the garbage mixing

One of the important stages of the compost process is to ensure adequate supply of air. During the first few days, the amount of aerobic microorganisms grew very fast, so it was needed much oxygen. The lack of oxygen will grow anaerobic microorganisms and odors, while slowing down the organic fertilizer. Therefore, be aware to ensure the amount of air is provided fully.

Step 5: Control the temperature

The activity of microorganisms is effective at 65 - 70 oC. Therefore, it is necessary to maintain this temperature for at least 3 days, after the first week the temperature will decrease and the incubation process will slow down. The process will switch to a plant stage with a temperature of 45 - 50 oC and other microorganisms will play a metabolic role until the garbage becomes an organic fertilizer.

Step 6: Control moisture

Must ensure moisture in the tank from 40 - 60 %

Step 7: Incubate

After 30 days, the garbage in the beds will fall like earth and temperatures below 50 oC. This indicates that it has reached the ripening process. It takes 2 weeks to make sure the compost is completely ripe.

Step 8: Screening

Organic fertilizer after incubation is raw size, it depends on the original material and the number of mixing times. In many cases, the product needs to be ready, the sieve size depends on the requirements of the local market (usually about 10 mm).

Step 9: Contain and close the bag

After the required size is screened, the addition of NPK and minerals may be considered.
