To put it another way, waste management can be defined as “the processes and actions required to manage waste from the point where it is first generated until it is finally disposed of.”
To put it another way, it is unusable. Getting rid of garbage, cutting back on it, finding new uses for it, and preventing it altogether all fall under the purview of an organization’s waste management system. It lessens the impact that waste has on a variety of factors, including health, the environment, and so on. In addition to this, it can assist in the reusing or recycling of materials such as paper, cans, and glass, among other things. The improper management of garbage can create conditions that are hazardous to the health of both living things and the environment.
The goal of waste management is to lessen the negative impact that waste has on human health, the environment, the resources of the world, and the aesthetics of the globe.
Instead of working to improve the health of industrialised nations, the objective of waste management is to lessen the negative impact that trash has on the health of poor nations. The presentation and discussion of information on solid waste generation, characterization, minimization, collection, separation, treatment, and disposal, as well as manuscripts that address waste management policy, education, and economic and environmental issues, are the primary focuses of this publication.
TYPES OF WASTES

- Commercial waste
- Domestic waste
- Agriculture waste
Why waste management is important?
- To improves human health
- To preserve the environment
- To protect animals and marine life
- To lower production cost
The rates at which garbage is generated are increasing all around the world. It was predicted that by the year 2020, the global population would produce 2.24 billion metric tonnes of solid garbage, which would equate to a daily waste output of 0.79 kilogrammes per individual. It is anticipated that the yearly garbage generation will increase by 73% from its levels in 2020 to 3.88 billion t in 2050 as a result of the rapid development in population and urbanisation. In spite of this, less than twenty percent of waste is recycled annually, while enormous quantities continue to be consigned to landfills.
Every year, India’s trash production totals 62 million metric tonnes. Approximately 43 million metric tonnes are collected, of which approximately 12 million metric tonnes are treated and 31 million metric tonnes are disposed in landfills. The collection rate is approximately 70%.
1.15 lakh metric tonnes per day (TPD) of municipal solid trash is generated in urban India annually, which equates to a total annual production of around 42.0 million tonnes. Of this total, 83,378 TPD is produced in 423 Class-I cities.
