Waste Management


With every passing year, a growing toxic fog creeps over the northern belt of India as the dreaded pollution season sets in along with the cold. The reasons behind this pollution are multifarious: toxic fumes from vehicles, dust and smoke from industrial factories, crop burning, and fumes from burning industrial waste. A complex problem such as this also requires and multi-pronged solution, which tackles the issue one step at a time.


Sources of waste can be broadly classified into four types: Industrial, Commercial, Domestic, and Agricultural. Waste is a vital part of everyday human existence. Waste can be produced from different sources.

Type of Waste:-

On the basis of Physical States :
Solid wastes
Liquid wastes
Gaseous wastes
Biodegradable Waste
Non- Biodegradable Waste
Hazardous waste
Non- Hazardous waste

Classification of wastes according to their origin and type:-

  • Municipal Solid wastes
  • Bio-medical wastes
  • Industrial wastes
  • Agricultural wastes
  • Fishery wastes
  • Radioactive wastes
  • E-wastes
  • Waste Management

Treatment and Disposal of waste:
When people think about solid waste management, they likely associate it with garbage being dumped in landfills or incinerated. While such activities comprise an important part of the process, a variety of elements is involved in the creation of an optimal integrated solid waste management (ISWM) system. For example, treatment techniques act to reduce the volume and toxicity of solid waste. These steps can transform it into a more convenient form for disposal. Waste treatment and disposal methods are selected and used based on the form, composition, and quantity of waste materials. Following are some of the most commonly used waste treatment techniques:-

  • Open dump/Landfills
  • Sanitary Landfills
  • Incineration Plants
  • Pyrolysis
  • Composting
  • Vermiculture
  • Bioremediation
  • Phytoremediation
  • Waste Compaction

Waste Management market in India: By 2025, the waste management market size in India is projected to be worth ~USD 15 Billion with annual growth around 7 percent. A growing economy, soaring urban population, rising living standards and increasing consumption levels are common trends in emerging economies across the globe

Sustainable Waste Management for Businesses:-There are many reasons to adopt sustainability as your main guiding policy in conducting business. With environmental problems becoming more prevalent worldwide, consumers seem to show a strong preference for businesses that adhere to environmental ethics. A sustainable business strategy can thus give you an edge over competitors. But business sustainability is tightly connected to waste management because any business activity generates waste that can harm the environment.

The Triple Bottom Line and Waste Management:- In terms of the Triple Bottom Line, how does waste management correlate with driving positive impacts for people, planet, and profit? In a nutshell, implementing a responsible waste management system for businesses and companies will help mitigate the climate crisis in terms of pollution prevention, among other things

People: The first P is for “people”, the societal impact of a company/business and/or its commitment in building a better society. As companies embrace sustainability in their business practices, they should also focus on generating positive effects for all stakeholders impacted by their business, including customers, employees, and ultimately community members.

Planet: The second P is for Planet, which translates into how businesses manage, monitor, and report their resource and energy consumption as well as waste and emissions output. Extractive industries that deplete our planet’s natural resources beyond its boundaries and heavily pollute the environment need to be held accountable for their unsustainable practices and to do better.

Profit: More and more people have come to realize their purchasing power as consumers in demanding better and more ethical business practices. This is evident inresearch by Nielsen which found that 48% of US consumers would “change their consumption habits to lessen their impact on the environment.” In 2018 alone, this sentiment translated to roughly $128.5 billion in sales of sustainable, fast-moving consumer goods.
