What is Waste Management ?
Waste Management refers to the various schemes to manage and dispose of wastes. It can be by discarding, destroying, processing, recycling, reusing, or controlling wastes. The prime objective of waste management is to reduce the number of unusable materials and to avert potential health and environmental hazards.
Waste management involves the regular collection, transportation as well as processing and disposal or recycling and monitoring of different types of waste materials. These services can save your business a considerable amount of money, and can also prevent the environment from being harmed.
Waste collection services are often provided for free by the local government. The collected wastes are disposed of by various methods, e.g. by landfill compaction and incineration. Solid wastes, most especially, are incinerated to reduce their volume by 80 to 95% and to convert them into gas, steam, ash, and heat. However, air pollution is a concern when disposing of wastes by means of incineration.
Thus, other means are encouraged, such as recycling, reprocessing, and re-use. Organic wastes, especially those that are biodegradable, are allowed to be decomposed so that they can be used as mulch or compost in agriculture, and the methane gas from the biological degradation be collected and used for generating electricity and heat. Liquid wastes, such as wastewater, undergo treatment producing sewage sludge that can be disposed of by incineration, composting, and landfill. Synonym: waste disposal.
