Food and agricultural waste of different consistencies requires different management techniques and handling equipment. Food and agricultural waste may be in the form of liquid, slurry, semisolid, or solid, waste, such as manure can change consistency throughout the system, all the year. The total solid concentration of manure is the main characteristic that indicates how the material can be handled.
State and local authority must be contacted for necessary permits obtained before land application. Many permits require ongoing monitoring of groundwater and possibly soil and plant matter. Hydraulic loading is often ignored. If the site has a high water table or low permeability, the amount of water that can be applied generally is reduced. In some food processing waste, the level of salt is too high for land application. Most food processing waste land application sites should be designed by a professional who has experience in these type systems.

After this, the concept of dust-bin has became essential part of our life.
The reduction of food and agricultural wastes is placed at the top of waste management hierarchies because the best means waste management is to reduce waste by not creating it in first place. The reduction of food and agricultural waste can also be achieved through the reuse of products. The reduction and reuse of wastes save natural resources, reduces generation of wastes and reduces the cost associated with food and agricultural waste disposal.
Due to industrialization, urbanization and increase in population density, there has been an increase in the accumulation of waste. The waste include radioactive substance, agricultural wastes, food wastes, industrial wastes, municipal wastes. Garbage and paper waste etc. There has been decrease in the availability of open land and space for disposal of waste due to intensive use of agricultural land for residential, industrial and commercial purpose. In order to reduce the load of food and agricultural wastes on earth, the collection, transport, recycling and disposal of food and agricultural wastes needs to improvised.
