ji, plastic covers are used to pack the milk. In our state of karnataka daily 17metric tonne of plastic is being used for packing milk. After usage of milk we can't track the status of where such huge amount of plastic is going into. Hence we can design a system of charging 10rs/plastic cover in which milk is packed and entrying the no. of packets purchased in a card.The next day the consumer has to return the empty cover and then avail the discount of 5rs/cover duly showing the entry in card.
