In the urban areas like metropolitan cities, tons and tons of garbage is generated each day because of various human activities. This waste is discarded with negligence resulting to high scale pollution. Garbage must be handled systematically so that its decomposition becomes more environmental friendly and organized. The waste must first be segregated into three basic types according to their composition; Biodegradable, Non-biodegradable and Recyclable. The biodegradable waste is sent for decomposition, vermin-culture or biogas plants. Through which we obtain manure or biogas. The model also consists of a replica of the Mithi river. And with the help of this miniature, these students are trying to demonstrate the devastating effects of the pollutants being released into the river by the local residents of the place. The students promote the 3R mantra for sustainable development and reduction of pollution and global warming: Reduce Reuse Recycle.


If you have heard of something called the ?waste hierarchy? you may be wondering what that means. It is the order of priority of actions to be taken to reduce the amount of waste generated, and to improve overall waste management processes and programs. The waste hierarchy consists of 3 R?s as follows:

  • Reduce
  • Reuse
  • Recycle

Called the ?three R?s? of waste management, this waste hierarchy is the guidance suggested for creating a sustainable life. You might be wondering as to how can you incorporate these principles in your daily life. They are not hard to implement. All you need is to bring a small change in your daily lifestyle to reduce waste so that less amount of it goes to the landfill that can reduce your carbon footprint.

   The three R?s ? reduce, reuse and recycle ? all help to cut down on the amount of waste we throw away. They conserve natural resources, landfill space and energy. Plus, the three R?s save land and money communities must use to dispose of waste in landfills. Siting a new landfill has become difficult and more expensive due to environmental regulations and public opposition.  

By refusing to buy items that you don?t need, reusing items more than once and disposing the items that are no longer in use at appropriate recycling centres, you can contribute towards a healthier planet.
