Segregation of Waste
How Does Segregation Work?
- Type of waste can be selected before disposing off from each loading station.
- The system (software) knows which type of waste is being disposed.
- Once the waste reaches the central collection area, that particular type of waste is diverted into the collector for that particular type of waste.
