Waste disposal or waste management refers to managing the waste from its initiation to its final removal. This includes collation, transportation, processing, re-cycling and finally disposal of waste along with monitoring, regulation and control. It also covers the lawful and regulatory aspects that relates to the waste management, including the instructions and guidance on recycling and disposal of waste management, etc.
The phrase usually relates to all types of waste, whether produced during the withdrawal of raw materials, the dispensation of raw materials into final goods, consumption of final good, or other human activities such as metropolitan (institutional, residential and commercial), farming and social (household hazardous waste, health care and sewage sludge, etc.) The objective of the waste management is to minimize the hazardous effect of waste materials on health, environment or aesthetics.
The practice of waste management varies country-wise (developed and developing nations), region-wise (urban and rural area) and sector-wise (residential and industrial). While urban regions may employ advanced machines and latest technology to supervise the waste, rural areas may be more dependent upon the human labour; residential areas may utilize safe and sound process whereas industries may utilize giant machines, etc in order to control the factory waste products. The waste materials at the institutional and residential level in the metros and cities are administered by the local authorities also known as Municipal Corporation; while the management of harmless industrial and commercial waste is accomplished by the generator of those waste.
I would now like to point out the most commonly used methods for waste management:
Landfills – This is managed by throwing the daily garbage in the landfills; it is the most common method used today.
Recovery and Recycling – Through this method, the useful items from the discarded is extracted for the next use such as conversion into energy, usable heat, fuel, electricity, etc.
Combustion or Incineration – In this method, community solid wastes are burned at high temperatures in order to convert the same into gaseous products or residue.
Plasma Gasification – Plasma is a basically an electrically charged gas. In this method, the molecular bonds of the waste are broken down due to the intense heat in the container.
Waste to Energy – In this method, the non-recyclable waste materials are converted into useful electricity, heat or fuel through various processes.
Composting – It is a natural process of bio-degradation; it converts the kitchen, plant and garden waste into nutritional food for the plants.
Waste Minimization – The best method is to minimize the creation of waste products by repairing the broken utensils, avoidance of plastic bags, etc.
It is important that we are protective towards our environment and always follow the 3Rs of waste hierarchy: ‘Reduce’, ‘Re-use’ and ‘Recycle’ in order to save our environment.
Thank You!
