Attempts have been 3. made sporadically to create useful products out of organic wastes by com- comps posing them or cooking them so that some of the residue can be sold for 4. fertilizer and for raw materials. However, even the wastes from incineration and wi ` must be disposed of ultimately. 5• "w Land fill has provided one means of disposing of these unwanted, largely Compa �. useless materials. Often a land .fill places wastes upon waste, thus solving 6. two problems by creating one, where otherwise useless lands have been pressi utilized for the disposal area. Finally, it is even possible to create useful of othe .� building sites out of heretofore marginal or useless land and otherwise ob- 7. jectionable waste materials. Such waste land filling in the long run probably can bE can account for only a part of the potential use for sanitary land filling. preven Unfortunately, great areas are required for sanitary land filling for large 8. .

The In most areas, land is becoming increasingly scarce and old sanitary land tary la fills are now being used for other developments. 1n general, this future use per cu was not contemplated during the.construction of the original fill. Development Much d of a land-fill site involves serious problems, some definite limitations, and with w: j substantial costs. Today (1968) the scarcity of land in the vicinity of cities The tt indicates that eventually it will become imperatilre to use all sanitary fill and th areas for higher development. Therefore, it will be necessary to build the trolled fill so that future developments can be undertaken at a reasonable cost. In late an other words, fills must be constructed so that future use will not be re- materia stricted. The increased cost of the higher standard of land-fill building will cases, AS be offset by the increased value of the land upon its resale or conversion to a most c second use.

T CHARACTER OF SANITARY LAND FILLS blocks, These The character of the sanitary land fill varies considerably with the com- relative munity, the nature of the wastes, and how they are handled in constructing to 2 ft the fill. The composition of the fill depends on the trade, commerce, and in- neat su: dustry of the community and on other forms of waste disposal, particularly ' of industrial.wastes. However, most wastes contain a number of major com- ponents which have a .significant bearing on the'utilization of the fill. These include: The , 1.
