1. Compaction – Soil Surcharge

• Soil Surcharge • Compact refuse

cell, extend airspace

2. Alternative Daily Cover

Tarp-o-matic

25

3. Landfill Reclamation

26

4. Compaction – Computer Aided Earth Moving System (CAES)

• Cell Capacity Extended

• Less Cover Material

• Reduced fuel use-less guesswork onpasses over trash
