Spanish architect and designer Omayra Maymó created Malta I, a four-tier plinth commissioned by Heineken that is made with barley leftover from the brewing process. The upcycled pedestal consists of a series of stacked brick-like forms that were created by combining the barley waste with cement.

This combination of materials yields a lighter-than-usual version of cement that has the potential to reduce the carbon emissions associated with traditional cement manufacturing processes.

In between these hybrid barley and cement blocks, there are lightweight glass tiers that help to aesthetically break up the design and also serve a functional purpose, as they can be used for storing small objects.
