Landfill Leachate Management

Leachate is liquid that drains through waste and collects contaminants. Its chemistry varies depending on waste type, landfill age, rainfall, geology and operations, making long-term management complex.

As waste breaks down and environmental conditions change, salinity, ammonia, metals and emerging contaminants such as PFAS can increase or fluctuate, affecting treatment performance.

We assess leachate chemistry, landfill characteristics, operational constraints and licence conditions before designing a site-specific solution.

Yes. Systems are designed to be adapted as chemistry and volumes change, maintaining compliance and cost control.

BeneVap is a submerged combustion thermal evaporation system that vapourises water directly from leachate, leaving a small concentrated residual.

Up to 90% volume reduction, over 99% ammonia removal, pathogen destruction through heat, and reduction of VOCs and heavy metals.

Both. Units are available as fixed installations or mobile systems and can be purchased or leased.

By maximising evapotranspiration and limiting deep percolation that would otherwise generate additional leachate.

Using detailed water balance modelling, pump and sprinkler selection, and transportable infrastructure suited to dynamic landfill operations.

Through foam fractionation systems that selectively concentrate PFAS into a controlled foam stream prior to trade-waste disposal.

Reducing PFAS concentrations can expand disposal options and lower transport and treatment costs.

All leachate solutions are delivered with qualified oversight, monitoring and documentation aligned to licence conditions.

Yes — BeneTerra operates under a statewide NSW EPA mobile leachate treatment licence, allowing short-term deployment without changes to a site’s licence.
