By adopting the concept of anaerobic digestion, the garbage in the dump site is decomposed to release landfill gas. This free source of energy can be utilised to generate electricity.
Despite being an attractive financial aspect, planned gas recycling offers other important benefits like:
- The odour nuisance from landfill sites is reduced.
- Fire & explosion hazards can be prevented.
- Gas migration is avoided
- Landfill site can be re-cultivated more quickly.
