(CNN)When you think of a factory, you might imagine a giant facility with huge chimneys belching steam. But consumer goods giant Unilever has developed a fully functioning production line inside a shipping container.
The company has over 300 factories in 69 countries, but this is its first experiment with what it calls a "nano" or "travel" factory.
Mass production lines allow manufacturers to make large quantities of products but using the same facilities to produce smaller batches of goods -- to test new ideas or to meet seasonal demand -- can be wasteful and inefficient.
Because of its size, the 40-foot container can be transported by cargo ship or truck to any location, says Unilever. It just needs a source of water and access to electricity to begin production.
The nano factory is currently in the Netherlands, in the middle of its first trial producing liquid bouillon, a cooked stock packed in a bottle. Unilever says the factory is making around 300 tons of bouillon per eight-hour shift.

Robots are an increasingly familiar presence in warehouses. At the south-east London warehouse run by British online supermarket Ocado, 3,000 robots fulfill shopping orders. When an order is sent to the warehouse, the bots spring to life and head towards the container they require. Scroll through to see more robots that are revolutionizing warehouses.

In response to the coronavirus pandemic, MIT collaborated with Ava Robotics and the Greater Boston Food Bank to design a robot that can use UV light to sanitize the floor of a 4,000-square foot warehouse in just 30 minutes.
