Everything you need to know about the world's first floating dairy farm

The three-tiered dairy, located in a port in the Dutch city of Rotterdam, aims to make dairy farming more sustainable by cutting waste and reducing the distance milk has to travel to consumers.

The 32-head herd is being grazed on the rooftop – or ‘cow garden’ – of a 20x20 metre concrete platform. They also have access to dockside pasture which they can reach via a bridge.

Milking is done by a robot, while robotic scrapers collect waste which is then dried inside the dairy’s own recycling centre and reused as bedding.

Additional feed is being broughtin from nearby breweries and vegetable packers, helping to reduce the amount of waste the city produces.

While the dairy had been scheduled to open last autumn, engineering challenges meant the cows finally arrived to their new home this week. The first bottles of milk are due to reach consumers by the weekend.

Minke van Wingerden, of property developer Beladon, the company behind the project, said: “This is an elaborate project, so we have run into a few unexpected issues.

"We had to redesign and reconstruct the ramp because the tide changes the water height by 2m, so the movement of the platform was damaging the shore.
