Landfill and Compost Leachate Treatment

Both landfills and compost sites generate leachate, a difficult wastewater to treat and one that often requires expensive hauling to distant municipal treatment sites or payment of steep surcharges for sewer disposal. If you’re paying more than 2-3 cents/gallon for treatment, you should consider onsite treatment with Digested Organic’s Ultrafiltration or Two-Step Reverse Osmosis platforms.

For most leachates, we can recover >95% of the wastewater as clean water suitable for discharge to nearby waterways, along with a concentrated waste that can undergo solidification onsite for disposal at the facility or be hauled offsite for disposal.

PFAS are a set of emerging contaminants that have been found in many landfill leachates. Our Two-Step Reverse Osmosis technology has been found to remove PFAS, along with other traditional contaminants like BOD and ammonia.

Integrating Anaerobic Digestion with Landfills and Composting Operations

New regulations banning the disposal of organic wastes in landfills aims to divert more waste to composting operations and anaerobic digesters.  If you currently own and operate a landfill or composting operation, now is a good time to consider adding an onsite digester to your facility so you can capture revenue from both tip fees and renewable energy.

  • A landfill is basically an inefficient anaerobic digester.  If your facility is already capturing landfill gas to run generators, you can boost your electricity revenues by generating high-quality biogas from digesting organic waste in a BioEliminator™.
  • Capture valuable tip fees from organic waste haulers by continuing to accept organics once bans go into effect instead of losing market share to other facilities.
  • Use the microbe-rich greywater effluent from the BioEliminator™ to keep the landfill moist, further boosting landfill gas production.
  • Use our NCWR to treat landfill leachate and reduce your surcharges and disposal costs.  See our recent blog post about a successful demonstration we completed.
  • Aerobic composting is a good alternative to landfilling organics, but food scraps and fats, oils, and greases can be strong vector attractants, odorous, and slow to compost.
  • Instead of composting these energy-rich materials, digest them in a high-rate BioEliminator™ to create renewable energy and a greywater effluent.
  • Use the microbe-rich greywater effluent from the BioEliminator™ to keep compost piles moist, further accelerating the composting process.
  • Digest high-energy feedstocks

    Divert food scraps and FOG to a BioEliminator™, quickly digesting odorous wastes that can be strong vector attractants.

  • Benefit from energy sales

    Increase revenues through net metering or a power purchase agreement by turning biogas into electricity.

  • Use heat from BioEliminator™

    The biogas from a BioEliminator™ can be combusted in a boiler or water heater to generate heat.  This can be used to keep buildings and equipment warm, boost landfill gas productivity (especially in winter) and keep compost piles warm year-round and speed up the composting process.
