Hyperthermophilic Aerobic Composting Technology

Technology / Service Summary

The Hyperthermophilic Aerobic Composting Technology is capable to treat a large range of biodegradables wastes at high temperatures due to the presence of specific group of bacteria.

Purpose

By composting organic waste, it is possible to significantly reduce the waste volume. It can contribute as one method of intermediate treatment to solving the problem against the tightness of landfill capacity due to the not segregation at final disposal and the organic waste after composting can be used as a fertilizer.

Feature

During the composting process, the fermentation temperature of 90oC or higher is maintained for a long period of time. After 45 days of fermentation, the total of organic waste is reduced into 5~15% of the initial volume. A major feature of this technology is that by using compost already finished as a compost activator containing the hyperthermophilic bacteria, it maintains ultra-high temperatures and significantly shortens the composting period, which normally takes 60 to 120 days.

Effect

・Composting at high temperatures kills pathogenic microorganisms and weed seeds.
・The composting process takes as short as 45 days.
・Organic waste volume reduction rate is 85-95%.

Notes

Organic waste (raw materials) such as food waste and sludges are mixed with compost activator and reach a high temperature fermentation under aerobic conditions due to microorganism activity to decompose the organic matter present in the waste. The organic waste volume can be significantly reduced, and after composting process can be used as a fertilizer for farmland and green areas.
