DMPQ- What is 4 Rs principle for Waste reduction?

  • Waste is everybody’s responsibility. A waste reduction strategy can be incorporated by each of us whether at home or at work by following the4 Rs principle.
  • This will not only reduce the amount of solid waste going to landfill, but turn waste into a resource & also save our fast depleting natural resources.
  1. Reduce:At home you can begin by purchasing things with lesser packaging, more durable & refillable items, carry your own shopping bag, avoid disposable items and reduce the use of plastics. At office one can cut down on paperwork, use electronic mail for communication.
  2. Reuse:You can donate your old clothes, books, phones and lots more. You can reuse old bottles, jars as storage bins and buy rechargeable items rather than disposable ones.
  3. Recycle:Segregate your waste for better disposal and purchase recycled/ green products. A ton of paper from recycled material conserves about 7,000 gallons of water, 17-31 trees, 60 lb of air pollutants and 4,000 KWh of electricity. You can recycle or compost your organic waste directly at source- leaving very little waste to reach the landfill. Watch this video of Vani Murthy, who composts in her own apartment.
  4. Recovery or reclaim:Various mechanical, biological and caloric systems and technologies can convert, reprocess or break up waste into new materials or energy. This means turning waste into fuel for manufacturing processes or equipment designed to produce energy. For example, the methane caused by rotting materials in dump sites can be recycled. Of course, this “R” is difficult for individuals to apply and applies more for industries or towns with a high volume of waste to manage.
