A machine that exchanges glass bottles and cans for refills to travel on the metro of Medellin was installed today in one of its stations to encourage recycling and promote environmental care. This social and environmental innovation project, which was launched under the name of 'Green Recharge' and developed by young local entrepreneurs, will allow users to receive 50 Colombian pesos in their cards for each article that they enter into the machine.
