In the basis of existing statistics in Iran, in average 35 percents of agricultural crops from product to consumption process converted to wastes which it can be guaranteed 15-20 million people nutrition of peoples. Agricultural wastes occurred in cultivation, pre-harvesting, harvesting and post harvesting process but the majority of wastes was related to both stages of harvesting and post harvesting. In agricultural products, wheat has a high importance because it’sa strategic and food staple. But the results showed that waste quantity in this food staple is notable. the wastes in cultivation stage consists of extra seed consumption that it’s estimated 20 percents and results of technical problem and using of abrogate cultivation methods. In harvesting stage the wastes has estimated (0.5-2 percent) for cutter plane loss (0.5-1 percent), for masher unit loss,(0.2-0.4 percent) for separator loss,(0.04-0.2 percent) for cleaner loss and other factors. Finally in post harvesting stage, wastes classification in 4 category include of transportation (5.5 percent), winnowing (0.2 percent), storing (4 percent) and converting wastes (5 percent) respectively. These static warn that waste management is indispensable. With regard to the results of the study, appropriate storage and processing of products after harvesting along with development of agricultural converting industries can be effective in wheat waste management. In addition, health observation before of harvesting will postpone product spoilage created by external and internal factors, so product can be useable for more time. Finally, it’s important that wheat waste management needs to regularly and long time …
