Ð  Ensuring quality control: If the quality of products is maintained, there will be a decrease in rejected products, thus
                   reducing waste. Automated monitoring equipment is now being used, which can help identify production problems at
                   an early stage.
                 Ð  Waste exchange: This is where the waste product of one process becomes the raw material for another. It represents one
                   way of reducing waste disposal through re-use.
                 Ð  Managing e-waste: With advanced technology, we have also encountered problems in managing e-waste like old mobile
                   phones, laptops, and television sets. It is important to have sustainable development and to plan judiciously for the
                   recycling of e-waste.
                 Ð  Use of eco-friendly materials: Scientists have discovered various materials that are eco-friendly, for example, banana
                   leaves and paper plates that are easily disposable, etc. These must be made easily available and their usage needs to be
                   encouraged.
