The process of collection, transport, disposal, recycling and monitoring of agricultural waste is called food and agricultural waste management is undertaken to recycle the food and agricultural waste so as to reduce the ill effects of wastes on environment, health and aesthetics. Various techniques are used for the management of waste which includes land-filling, incineration, anaerobic digestion, pyrolysis, plasma gasification, recycling, composting. Anaerobic digestion produces bio fuel in the form of biogas. Plasma gasification results in the generation of electricity from waste. Recycling of food and agricultural waste involves the collection, sorting and reprocessing of waste into new products. Vermin composting is the preferred form of composting as it results in the formation of vermin compost called black gold due to the presence of rich nutrients and growth promoting factors in it.
The process of collection, transport, disposal, recycling and monitoring of food and agricultural wastes is called food and agricultural waste management. Food and agricultural waste management can be costly so it is important to understand the various effective, sustainable and safe means of its management. The three points ‘R s “Reduce, Reuse, and Recycle have become basic tenet in food and agricultural waste management due increase in generation of wastes, increasing in processing costs and decrease in available landfill space. There should be flexibility in food and agricultural waste management systems in light of changing environmental, social and economic conditions. To optimize, evaluate, adapt and define food and agricultural waste management systems, the information and feedback can be obtained from system analysis.
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.
The wise strategy has to be taken with multi layered technology solutions for the food and agricultural waste management in long term basis. Japanese latest food and agricultural waste technology and equipments are available but need to be transfer to the poor and developing countries at lowest cost. Similarly many developed countries must come forward to share their know how to the developing countries at minimum or without any cost for the best management of food and agricultural waste. It is time to think, act seriously without the border of the country because we have only and only one Blue Sky and Blue Earth, must keep continue blue and clear for the next coming generations, years, decades and centuries ahead.
Presently, reducing food and agricultural waste has become the main agenda of many governments, NGOs, and other societies in many countries. Food and agricultural waste is nothing but remnants of our used stuff as vegetables, food stuff, animal waste etc. which people are practicing and reusing them daily by repurposing for their utility since ancient times. Due to modern urbanization and industrialization, the concept of repurposing has changed by new waste management and recycling technology invention, together with use and throw concept.
