I live in Greece, a country which recently introduced a policy for not using plastic or paper bags in supermarkets. Just like the rest of the world a small amount of money has to be spent in order to buy reusable shopping bags made from other materials.
My idea was based on this concept of innovative thinking in regards to a better and safer future for our environment.
There will be three sizes of rubber bags which will be colour coded according to the abundance of each rubber colour (so no extra work has to be put in painting them the desirable colour, if possible). The sizes will be decided according to shoe box sizing, enough volume for apparel shopping, ball shopping etc.
It is up to the companies that want to integrate this bag to their business to decide what will be the amount of money charged for this reusable shopping bag or if it will be given out to the customers for free. However, as we live in a world were underdeveloped or developing countries need our help, I came up with the idea that we could offer the profit from the bags to such countries in order to encourage athletic activity and raise awareness for the importance of sports in every individual's life, especially in children's lives. Something which would also link with Nike's values.
