Marco Renna – LEFT(L)OVER

In precast concrete plants, surplus concrete is prepared to avoid shortages during casting operations. However, this surplus, which represents around one to four tonnes per day, is generally discarded. The plant then produces large blocks, which are transported to a landfill site where they become gravel.

LEFT(L)OVER aims is to reuse this surplus to create street furniture. Moulds are supplied to the companies to replace their blocks. This collaboration establishes a mutually beneficial exchange. The moulds fit in perfectly with the factory’s habits and logistics. They consist of two detachable parts with the space required for efficient unloading of the concrete and optimisation of the process.
