Landfill Diversion ď‚— The process of diverting waste from landfills is known as landfill diversion.

Measuring success of Landfill Diversion ď‚— The success of landfill diversion can be measured with respect to the reduction

The bottom of the landfill must be lined to prevent water contamination.  Engineering preparations and planning must be carried out to ensure the success of the landfill.  To ensure success and sustainability, permanent supervision must be present in all stages of the landfill.  The placement and compacting of waste must be done to prevent pest and vermin infestations.

Types of Landfill (Cont) Secure Landfill ď‚— It is used to deal with hazardous waste. A secure landfill requires much
