Types of Landfill Gas Collection
There are two main types of Landfill gas collection:
Feedstocks for Landfill Sites
- Organic wastes
- Pretreatment: none
- Qualifications: none
Feedstocks for Bioreactor vessels
- Organic wastes
- Pretreatment: sorting pre-treatment
- Qualifications: The waste must be contained, compacted and covered in a vessel.
Products of Landfill gas collection include:
- Intermediate products: Biogas composed of methane, carbon dioxide, nitrogen, hydrogen, hydrogen sulfide and oxygen.
- Carbon dioxide for possible use in greenhouse operations, and biofertilizers
Advantages of Landfill Gas Collection
- In the case of bioreactors, reduced material in landfills.
- Reduced release of methane and other gases to the atmosphere and the beneficial use of these gases.
- Significant greenhouse gas stabilization benefits.
- Fully commercialized worldwide.
Sustainability and Environmental Concerns
- Fully sustainable as long as humans produce waste that would go to landfills or bioreactors. The key factor is the sustainability of the biomass used in producing materials ending up in landfills. There are major environmental benefits from preventing the release of biogas generated in landfills to the atmosphere.
- Added renewable energy to the nation's energy mix. Cleaner environment if landfills are properly maintained. Availability of decentralized energy, both electric and thermal, to the community. This would be of considerable value in the event of a regional or local energy emergency
