Plastic bags

What do you do with plastic bags? I normally store them for future use. But what about the bags which are not clean from inside?
Normally we throw them away. Next time you have such unclean plastic bag, dont throw it away, use it as dustbin lining. Doing so will reduce at least one plastic bag in the waste.
I know we can not stop completely using plastic bags/polythenes practically. But try to minimize their use by taking your own bag for shopping, especially while buying vegetable, Fruits. Also reuse them as much as possible before throwing them away.
One more suggestion - the unclean bags can also be used to throw away food waste which needs to be sealed in plastic before throwing away e.g. leftovers or spoilt food items.
The packets of chips, groceries and bags of packeted food in it, milk plastic bags can also be reused this way.
I hope it will reduce the plastic waste everyday by some mean.
Also share if you have some more ideas.
