An Alternative to \"Dry Tombs\"
The bioreactor technology is gaining popularity in North America and Europe, and has been demonstrated at various landfills. A bioreactor landfill is a sanitary landfill that uses enhanced microbiological processes to transform and stabilize the decomposable organic waste within 5 to 10 years of implementation, compared to 30 to 100 years for \"dry\" Subtitle D landfills. Engineered bioreactor landfills (see Figure 1, below) can provide a more controlled means by which society can reduce the environmental impacts of landfills on the surrounding local environment.

Benefits
Engineered bioreactor landfills can provide the following economic and societal benefits:
Planning and Design
The planning and designing of a bioreactor landfill requires knowledge of the following:
Legal issues, regulatory constraints, costs constraints, and public input may also influence planning and design. Because the system must function over the life of the landfill, SCS designs are flexible enough to be adapted to regulatory changes, technological advances, economic conditions, and variation in waste and leachate characteristics.
