ARC - Bio Reactor Landfills Technology
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.
- 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.
- 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
As you can see the increase in leachate recirculation results in increased airspace utilization, our experts can assist you to maximize the airspace utilization.
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.For the bio reactor design and how to optimize the land fill gas generation and utilization of airspace in the land fills contact us
