Waste management has come to stay as one of the most controversial, well researched and analyzed subject of the modern industrial world. With production and commercial activity on an incessant rise, it is a natural fallout for the quantity and the nature of waste products to change dramatically, raising a global concern.
Study of waste management has always occupied a major attention owing to the importance it holds in the contemporary world. From conferences and summits to volumes of study and reference material being prepared on the matter, the issue surely holds center-stage as far as public and administrative attention is concerned.
In the study of the waste management concept, it is very important to pay careful attention to various individual aspects of the process, which also give a reflection on the entire gamut of causes, solutions and remedies of the problem.
To begin with, waste management is essentially defined as the collection, transport, processing, recycling and disposal of waste materials or products. Such waste materials can be broadly defined into various categories such as household waste, hazardous waste, toxic waste, hospital waste many more. There are a number of waste management methods that are generally followed in accordance with the nature and quantity of waste materials and the processing needed in relevance of the same.
The first category of processes relevant to the waste management concept is the series of disposal methods that might be followed. The first and most common disposal method followed is the concept of landfills, which basically involves burying of the waste of the purpose of disposal. In the last few years, this method of waste disposal has often met with a lot of criticism especially for solid waste in view of the environment hazards.
Incineration is another common method of waste disposal, involving combustion of waste material, conversion of waste products into heat, gas, steam and ash. This method of waste disposal is used to dispose of various categories of waste including, solid, liquid as well as gaseous.
Moving on, the next crucial process as a part of the waste management concept is the step of recycling, which is basically the process of processing waste products to recycle, reuse or recover material of productive value. Some of the most effective and popular methods of recycling include physical reprocessing, biological reprocessing and energy recovery.
The series of avoidance and reduction methods followed by the industry today are another important aspect of the waste management concept. Such methods of avoidance include the reuse of second-hand products, repairing broken items as against buying new ones, designing products to be reusable, encourage less use of disposable products and many more.
