An environmentally friendly coffee machine and a way to turn used coffee grounds into a new type of ink are helping to increase the green credentials of one of the most popular beverages in the world.
Globally, more than 2 billion cups of coffee are consumed every day. At a rate of around 2.64 cups per person per day, Finland takes the crown as the world’s largest per capita consumer of coffee.
However, the traditional steam-pressure coffee machines you see in coffee shops have barely evolved since their early development in Italy around the start of the 20th century. Updates have been just incremental improvements. According to Rafael Muñoz, from Spanish company Iberital, these machines are energy inefficient as they have no insulation or programming for heating.
