Abstract
Landfill sites or other refuse deposits are temporarily covered by sheet material between successive filling or dumping operations. The sheet material may be left in place and more refuse deposited on top, or removed and re-used. The material is preferably woven, biodegradable and permeable, such as hessian. A number of sheets of the material may be placed together side-by-side and joined together such as by stitching, stapling or staking.
