The scarcity and expensiveness of the organic substances improving the physical, chemical and biologic structure of soil have caused the studies related to the usage of agriculture based industrial refuse which is a source of organic substance to increase. On the other hand; the increase in the population and along with it in the number of factories processing food cause the food refuse to increase and correspondingly cause the limited water and soil sources to be polluted. These problems posed by waste streams speed up the studies related with reducing, utilizing, and increasing the utilization efficiency of residue and refuse amounts and related with the effective use of sources. In this compilation, general information on composting and usage as fertilizer of whey, which affects life negatively and causes pollution when dropped in the environment because it consumes the oxygen but contributes to the soil when used for fertilization, and of olive mill wastewater and prina, which are posing an environmental problem for Turkey, is given. Keywords : Whey, olive mill wastewater, prina, compost, organic fertilizer
