MICROBIAL BIOREMEDIATION FOR LANDFILLS

Leachate Treatment and Methane Recovery

For the past 21 years Alpha Omega’s proprietary technology for eliminating hydrocarbons, pesticides, chemicals, and heavy metals is readily adaptable to cleaning soil polluted by these substances such that it can be used as a capping material for landfills in as little as 2-3 months as opposed to years.

At active landfills, microbial mixtures are sprayed on the accumulating landfill waste that is still open, jumpstarting the degradation process. This reduces the organics and metals that leach out into wetlands or treatment lagoons.

Alpha Omega has the microbial process to handle all aspects of a landfill’s major problems (leachate, high cost of running a landfill, finite space and available sources of clean soil to cap waste) at significantly less cost and in shorter time, while providing new products and sources of revenue for the waste management industry in the natural gas, clean water and soil arenas.

Alpha technology can also be used in several ways to enhance a landfill’s viability, affecting its bottom line while increasing its profit margin. The methane produced in landfills can be captured and used for energy. Microbes can be injected into the landfill to stimulate an increase in the production of this renewable resource from capped landfills. If the goal is to reduce methane production, a reverse process is also available.

We have designed reclamation systems such that landfills become producers of clean water and sources of natural gas, while breaking down waste, and greatly limiting the need for new landfill sites, enabling landfills to become good neighbors rather than “persona non grata,” at relatively little overall cost.

Landfill Sites 

  Ohio:
Clean gasoline contaminated soils – 15 Petro cells over 7 years period;
Clean BTEX/TPH, metals and semi-volatiles involving 10 Petro cells over 5 years; closure achieved & soil used for caps in 1-2 months.

Wisconsin:
10 cells in 2 years – soil was cleaned and used as cap in 1-2 months. This site typically processes 20,000 tons of waste with microbial consortia.

  1. PETRO CELLS
    Landfills that accept soils contaminated with COC's associated with underground storage tanks, above ground storage tanks and hydrocarbon (VOC's) spills need to be able to clean and move the material for use as caps or for sale as top soil. Our technology has been used for this purpose at landfills in Ohio and at a soil recycling site for over seven years. We have reduced the time it takes to clean and move these soils from 4-6 months to 2-4 weeks.(BTEX Groundwater report, Midwest 2 report)
  2. LANDFILL LEACHATE
    The movement of surface and/or ground water off the site can present a major problem if the water contains COC's that pollute wells and/or surface water run-off. The injection of Alpha Omega’s formulations into injection wells can clean and maintain clean ground water. The use of microbe injected carbon pellets in tough, permeable bags; planting wetlands in ditches, catchment basins, etc.; and spraying microbial formulations along the banks, ditches, etc. will prevent off-site contamination.(Kentucky report, Michigan report)
  3. ENERGY PRODUCTION COLLECTION/METHANE
    Many landfills, like many underground coal mines, produce methane and hydrogen sulfide gas. Hydrogen sulfide can be controlled by injecting microbes that break the H-S bonds, producing sulfur and free hydrogen which quickly bonds to oxygen produced by the microbes to form water. Injection and capture units catch the methane and transfer it to an energy receiving unit so it can be sold as natural gas. If more methane is desired, microbes injected into the landfill can produce methane. Should you choose not to tap this excellent energy source, microbes can "turn-off' the methane producers and reduce methane to compliance levels. (The Theta Process, Desulfurization-The Lambda Process)
  4. CAPPING AND EROSION CONTROL
    The soils used to cap the landfill should be land-farmed in with microbes, humates and nutrients prior to planting. Grasses, such as pampas grass grow quickly, but perennial rye grass, alfalfa, lespidezia, crown vetch and other similar nitrogen-producing legumes have much better rooting systems and grow well in disturbed soils when they are treated with microbes, humates and nutrients. The next succession of plants is based on the projected use of the landfill when it is full and abandoned. The use of microbial consortia and plants (phyto-remediation) has multiple applications for landfills. (Bio-Carb & Wetlands)
  5. HAZARDOUS WASTE LANDFILLS
    The same techniques as above apply, only the microbial consortiium formulations are changed to address the specific contaminants of concern.
