Arc Southern has alliance with Alan Environmental which provides the technology for the bioreactor design.
The single most valuable component of landfill design and operation is conservation of airspace. Airspace is what is being sold by landfill owners and operators. Most landfills are permitted to a certain volume or height limit. The more tonnage of waste or revenue generating materials that can be place in a cubic yard, the more the life of a landfill can be extended. There are several methods that can be used to increase the life of the landfill by increasing the amount of waste that can be disposed of in the permitted volume as shown below
Arc Southern has methods available that can use the starting or existing measured density of a landfill and accurately determine the final density based on the design height of the landfill (mechanical or primary settlement) and based on estimates of biodegradation (biological or secondary settlement).
Arc Southern is uniquely qualified to assist the waste industry in justifying and selecting the appropriate liquid waste streams that will increase immediate landfill density (as no volume is consumed), increase immediate compaction at the working face and provide long-term stabilization or degradation rates in the landfill.
Other new revenue increases could be realized at sites where gas to energy projects are viable and leachate recirculation and addition of other liquids could increase gas production from 50% to up to 5 times compared to the “dry” Subtitle D landfill. Arc Southern has innovative landfill gas system conceptual designs that can help remove gas very effectively from “wet” landfills.
Leachate recirculation in the same area of the landfill many times over will allow the landfill to increase moisture content to field capacity (40-50% moisture,recommended by bioreactor experts) that will help optimize degradation rates. We have technology which will help you optimize the degradation rates.
What are the benefits of Enhanced Recirculatio?
Landfill Gas Production Increase by 50 to 100 percent
Carbon credits if monitored appropriately
Leachate disposal savings
Airspace or Density gains up to 2,000 lbs/cy achievable
Reduction in Final Cap and PCC costs
Central Disposal Facility Bioreactor Data
Airspace Utilization & Leachate Recirculation
As you can see the increase in leachate recirculation results in increased airspace utilization, our experts can assist you to maximize the airspace utilization.
Moisture Impact on LFG Generation
As you can see that increasing the moisture content has a huge impact on the landfill gas generation. We can work with you to design the rate of LFG generation, to better server your end customer.
