I am sharing an idea on wastes. Definition of wastes need to be reviewed by the experts seriously. I don't find any item in wastes which has no economic value. Every item, which we treat as wastes, speak a lot about its history, its origin and value and can be reused and recycled in producing marketable items for economic benefit.
