HULâs âSmart Fillâ machine takes on refill pouches, zero waste stores⦠Share Via: ⦠But how likely will it change consumer behaviour? Will the eco-friendly âwokeâ citizen go the extra mile? After years of relying on refill pouches, âkiranaâ stores and zero waste businesses, consumers finally have a more eco-friendly alternative to buying Hindustan Unilever (HUL) products. HUL has launched an initiative, called a âSmart Fillâ machine. It is an in-store vending model for its home care products, and its aim is to reuse, reduce and recycle plastic. HUL is attempting to incentivise the use of this machine and reusable bottles by offering a discount. If the consumers bring in their own bottle, they are offered a Rs 30 discount. If they choose to purchase a âSmart Fillâ bottle (which can be subsequently reused), then they will get a Rs 15 discount.
