Often, fruit and vegetable waste is generated before reaching consumers, due to programmed overproduction and unfulfillment of retailer quality standards. Each year, an estimated one-third of all food produced for human consumption is lost or wasted world-wide. Hence, wastes leade to environmental problems due to its high biodegradability, represents a loss of valuable biomass and an economic cost for companies. The solution to reduce the amount of vegetable waste sent to the landfill station is to find ways to reuse them. Different strategies for reduction, reusing and recycing of fruit and vegetable waste have been proposed globally. In the present study, were analyzed the conditions to regrow onions (Allium cepa L.) from the scraps at different parameters. Culture medium is the most important part of plant tissue culture. Culture media like as soil provides to cultures the necessary inorganic nutrients. In addition, they also provide the necessary organic compounds such as vitamins, and carbon source, which are usually produced in plants. The soil provides a physical support for regenerated plants. The liquid medium enables explants to keep a constant maximum contact with nutrient supplies. A selective reagent may also be included in a culture medium to restrict the growth of certain cultures. Therefore, medium formulas vary depending upon the purpose of plant tissue culture. Different media may also be used during a plant tissue regrow process. Another important function of a culture medium is creating a necessary environment for the plant grow. Thus, light and air are indispensable in photosynthesis and regeneration of plant tissues. The thickness of the reproductive part has a great influence on the subsequent development of the plant. When the axillary bud (terminal bud or apex) is damaged, the plant grows harder. At the insignificant deterioration of the axillary, the plant grows more rapidly and more new leaves are generated.
