In rural indian village stores, shopkeepers generally display all their products like rice, salt, chilli powder etc in a sack. The buyer comes and examines the quality of the grain or powder and orders him the amount required. The shopkeeper then weighs the required amount and then packs it in a newspaper and ties it using choir thread. Shopkeepers generally maintains different sized newspaper cutouts and choir threads for the purpose of packaging. He/She is already trained in packaging powered products like salt, chilli powder etc using newspaper and thread. Packaged chilli powder etc are costly for the Rural population so they generally prefer the powders that comes from local mills etc. The local mills generally supply it to the shopkeeper in large sacks.
If we could supply shampoo etc in powdered format and supply it to these shopkeepers in sacks, the same way how local mills supply chilly powder etc. Then the shopkeeper would employ the same method of packaging for shampoo powders as well. This avoids the use of plastic for packaging and hence the plastic waste.
