Considering natural energy elements such as Water, Air, Sun, Earth and Animals. Ideal solution to this problem was found to be Nature itself. As consumption of small packaging can not be eliminated. not a human behavior can be changed. Thus a packaging material is used such that after some per-processing, it will be inert to react to contained thing. after consumed by user. it can then be post processed simple as boiling in water or frying in oil, at home or at local centre. Then it is original material as it was before packing. thus nature will take care of eliminating it.
For example sugar cyrup is used as packaging material. some process is done to make it inert. after use, it can be boiled, fried to remove added layer. then it is sugar cyrup again. which can be eliminated by water or air.
