German designer Julian Lechner has combined used coffee grounds into reusable cups.
Lechner collects leftover coffee grounds from his local cafes in Berlin and combines them with natural glues and particles of wood from sustainable sources to produce a liquid that can be injection moulded to create usable objects.
Once set into the required shape the material is hard and waterproof enough to withstand cleaning in a dishwasher.
Lechner said: “The amount of daily coffee consumption worldwide is growing thus the potential of reusing its waste for further uses is enormous.
The cups are available to buy as individual units, in pairs or as a set of four.
