Sanitary Landfills Engineering principles used to: confine waste to smallest practical area reduce waste to smallest practical volume cover waste with layer of compacted soil (or tarps)each day(finishing cover is ~50 cm or more of compacted clay-rich soil) NOTE:Compaction and subsidence will continue after site is closed;any further development must be able to accommodate these potential problems.
