a collaboration of biological systems

The aim of the co[w]work project is the production of bio-composites from waste materials from the dairy cow industry through the use of energy self-sufficient processes with the help of bacteria, enzymes and other biological substances. It shows two different material chains completely derived from this industry’s waste:

The first concept harvests the bioplastic PLA (polylactic acid) as well as nutrients for calcium carbonate producing bacteria from whey, a by-product of the cheese industry. The final biomineralised PLA composite offers surprising mechanical properties.

The second concept makes use of lignin derived from manure. It is constructed by computer-controlled wasps into very complex shapes. Also, here the final biomineralisation coating by bacteria allows sturdy and waterproof structures.
