Coffee morphoses

Between 18% and 35% of food waste is unavoidable. This generally consists of material with a good composition of solids and fibre that is generated during the preparation of food or beverages, containing parts that are considered inedible. One such waste product is coffee grounds.

Globally, around 9 million tonnes of coffee beans are consumed each year. Around 80% of the ground beans remain as waste after the beverage has been prepared. Binding this residue with natural binders creates composite materials with various properties. The composition, choice of drying method and final finishing of the material also affect its properties.
