Waste Management

Waste can be of many forms like solid waste, liquid waste or gaseous waste. These waste products can cause pollution to the environment and hamper to all life forms. Hence waste management is crucial for the protection of the environment and health. Waste management is the activities that are put into actions to manage waste from its inception to its effective disposal. Waste management deals with all types of waste whether industrial, biological or households. It includes collection, transportation and disposal of garbage or sewage and treating solid waste and even recycling items that can be reused.

              

                  With increasing population and urbanisation, waste production has increased on a greater scale. The practice of uncontrolled dumping of waste on the outskirts of cities and towns without proper treatment creates a serious environment and human health problems. The aim is to minimise waste by extracting maximum possible benefits and lower its effect on health and the environment. We are familiar with the “3R” that is Reduce, Reuse and Recycle. This waste hierarchy is the main concern of most of the waste management strategies. The base of the pyramid is ‘Reduce’. It comprises measures to prevent the generation of waste. Next comes ‘Re-use’, which objective is to look for alternatives available for the use of waste that has been produced. The last step is ‘Recycling’ where the waste materials are converted into new materials reducing the consumption of fresh raw materials. It is a resource recovery practice. This helps in reducing energy usage and pollution as well. After this comes material recovery and lastly disposal in landfills or incineration. In the Incinerators, the solid organic wastes are subjected to combustion convert waste material into heat, gas, steam and ash. 

The sewage sludge that is produced by waste water treatment process can be disposed of by incineration, composting and landfill. Organic recoverable materials such as food scraps, paper products can be decomposed and then used in agricultural purposes. Gaseous waste like methane can be captured and used for generating heat and electricity. Products that are recycled commonly includes aluminium such as cans, copper such as wires, paper, polythene, tyres, glass bottles, PVC and many more. The objective is to minimise waste production, their treatment and proper disposal as well as a palimpsest that marks waste management policy..
