Decomposition process
A clear pathway from collection to safe reuse—as organic fertilizer for agriculture.
- 1
Separate collection
Used biodegradable plastic bags should be separated from organic waste such as kitchen waste and garden waste during disposal to avoid mixing with conventional plastics or non-biodegradable materials.
- 2
Pretreatment
Mix organic waste (including shredded plastic bags) into industrial composting plants, adjust the carbon-to-nitrogen ratio and control moisture content.
- 3
Thermophilic fermentation
Maintain a constant temperature in the sealed reactor, perform periodic aeration, and ensure adequate oxygen supply.
- 4
Degradation monitoring
By measuring carbon dioxide emissions, the biodegradation rate is calculated, and humus soil is produced once the standards are met.
- 5
Product utilization
The final product is harmless organic fertilizer, which can be used in garden or agriculture.
