Don't be Plastic! Is essentially a lipstick refill system. Cosmetic packaging produces 30% of all plastic waste on the planet, and we could reduce the waste crated if we reuse parts of the packaging.
In our system when the customer use up a lipstick, they could go to a local cosmetic store to refill the lipstick.
There would be a machine that is easy to operate, where you could place the empty lipstick case in, push a button, and a new stick of lipstick (could be in a different shade) snaps into the case.
This system would therefore eliminate the amount of empty plastic lipstick cases produced, and still manage to offer a variety of lipstick shades for the customers to choose from.
Also, the refill system will be more affordable to the customers as the cost of lipstick cases is now reduced. There could also be an incentive system that give discount to loyal consumers. For example, if you refill lipsticks 5 times your could get a free refill.
