Meatless hamburgers have arrived in Argentina, following the growing world tendency of veganism, which has had an impact on the traditional fast (junk) food chains. In Buenos Aires, the Mostaza chain has launched its Mega NotBurger line, in alliance with Notco a start-up and recent Argentine unicorn, which elaborates food and proteins out of plants.
A US start-up company has a solution for people who want to eat meat, but don't want to harm animals either: 3D printed meat. The 3D printing technique is already being used to create things from bike parts to chocolate to dental crowns and bridges. And scientists are working towards using 3D printing to make organs for transplant.
