Moisture – An important factor
Collection of MSW
Collection is an expensive part of waste management, and many new devices and methods have been proposed in order to cut costs.
They are as follows:
- Garbage grinders
- Pneumatic pipes
- Kitchen garbage compactors
- Green cans on wheels
- Transfer stations
- Route optimization
Garbage grinders:
- Garbage grinders reduce the amount of garbage in refuse.
- Frequency of collection could be reduced.
- Twice-a-week collection is only needed in warm weather when garbage decomposes rapidly.
- Garbage grinders do put an extra load on the wastewater treatment plant, but sewage is relatively dilute and shredded garbage can be accommodated in both sewers and treatment plants.
- The increased burden may be problematic in water-short communities.
