Mixed municipal waste is a major problem for further procedures use of valuable raw materials from its composition. In composition of mixed municipal waste we can often found biodegradable and biowaste that should be collected separately. Mixing biodegradable components with other municipal waste leads to the loss of their valuable properties that can be used on the further process of recovery. In the biowaste managment as well as mixed municipal waste, it is necessary to keep the order of priority of waste managment and set a hierarchy of priorities that represent the best option for responsible waste managment, environment, human health and a wholesome community. Primarly we are referring to the two most desirable option, the prvention of waste generation, and prepare for a new recovery. Preventing the generating of biowaste implies responsible behavior, such as treatment of food in everyday life, while preparing for a new recovery, when it comes to biowaste are related primarily to sorting or separation of biowaste from municipal and/or biodegradable waste that is frequently replaced with biowaste, and whose composition includes some components such as paper and cardboard that are not included in the composition of biowaste. Since it is impossible to talk about biowaste without mentiong mixed municipal waste and biodegradable waste, this paper shows quantitys of these types of waste, and some of the methods of recovery that we can use in biowaste managment. Special emphasis is placed on composting as an environmentally acceptable method that can be practiced from households to industrial plants, as well as producing of biogas which is shown to be a good method of biowaste recovery, producing the gas, and reducing the biodegradable and biowaste in landfills.
