AB  - Large amounts of polymers are discarded worldwide each year, leading to a significant
polymer waste in natural environment. The upcycling has been found as an efficient way to
transform polymer waste into high-value biomaterials meeting the conditions required for
circularity by being indefinitely recyclable, without reduction in value or usability.
The presented study refers to the upcycling of commercial biopolymers into bacterial
nanocellulose. Polymer blends, consisted of biodegradable polymers, such as poly(lactic acid),
PLA, poly(butylene succinate), PBS, and poly(ε-caprolactone), PCL. Polymers were hydrolyzed
and the obtained hydrolysates were investigated as potential carbon source for
K. medellinensis ID13488 growth and nanocellulose production. Degradation products were
analyzed using HPLC analysis. Different growth media, including tap water, HS medium,
absence / presence of glucose, were tested and bacterial nanocellulose growth was
confirmed under the most of the tested conditions. Once the BNC growth was set up, the BNC
production was scaled up and the obtained material was investigated in terms of structure
confirmation (FTIR analysis), thermal properties (DSC/TG analysis), morphology (optical
microscopy, AFM analysis) and crystallinity (XRD analysis). Finally, the full life cycle of mixed
biopolymers: from biodegradation to revalorization of end products into bacterial
nanocellulose appeared as perfect model approach to plastic circularity.
