- accelerates the decomposition and stabilization of waste.
- leachate is injected into the bioreactor to stimulate the natural biodegradation process.
- needs other liquids such as stormwater, wastewater, and wastewater treatment plant sludges to to enhance the microbiological process by purposeful control of the moisture content
- differs from a landfill that simple recirculates leachate for liquids management. (landfills that simply recirculate leachate are not optimized bioreactors).
- Moisture content is the single most important factor that promotes the accelerated decomposition. The bioreactor technology relies on maintaining optimal moisture content near field capacity (approximately 35 to 65%) and adds liquids when it is necessary to maintain that percentage. The moisture content, combined with the biological action of naturally occurring microbes decomposes the waste. The microbes can be either aerobic or anaerobic.
A side effect of the bioreactor is that it produces landfill gas (LFG) such as methane in an anaerobic unit at an earlier stage in the landfill’s life and at an overall much higher rate of generation than traditional landfills.
