The exhibit presented at the CLIENT Conference 2024 featured an innovative concrete test specimen in the shape of half a cassava tuber from the INFRACOST project. The four integrated chambers are filled with cassava peel, cassava starch, cassava charcoal and cassava ash – the most important processing stages of cassava for sustainable building materials.

The use of these components saves water in the concrete and increases its strength. Cassava charcoal and ash serve as low-carbon or carbon-negative building material components and help to significantly reduce the carbon footprint. The dark colour of the concrete comes from the charcoal it contains.

The exhibit illustrates how agricultural residues can be used as innovative solutions in the construction industry. More information about INFRACOST can be found on the project page.
