The rapid increase in global plastics production is
also causing an accelerated environmental
pollution. Recently, biotechnological solutions and
enzymatic recycling of poly(ethylene terephthalate)
(PET) waste stream have been put forward and
commercialized1. Increasing recycling and
upcycling rates is the most effective model
approach to plastic circularity. However, mixed
plastic waste is still quite a challenge for both
recycling and upcycling technologies. This study is
focused on the eco-conversion of plastic waste
containing poly(ethylene terephthalate), PET, into
biopolymer, bacterial nanocellulose. Polymer mix
contained selection of commercial biodegradable
plastics (poly(lactic acid), PLA, poly(ε-caprolactone),
PCL, poly(hyoxyl butyrate), PHB) and PET. This
mixture was hydrolysed under aqueous conditions
and hydrolysate was used as carbon source for
Komagataeibacter medellinensis ID13488 and
bacterial nanocellulose (BNC) production. HPLC
analysis confirmed ...the presence of monomers and
dimers of polymer mix components indicating
existence of potential substrates for BNC
production. BNC production by K. medellinensis
was investigated and optimized in ter of the
amount of carbon source and growth conditions.
Under the most efficient rate in ter of yield, BNC
production was scaled up and the obtained
biopolymer was characterized. The structure of
produced BNC was confirmed by FTIR analysis,
thermal properties by DSC/TG analysis, and the
morphology of material by optical microscopy and
SEM analysis. This research demonstrates how to
put the mixed plastic waste stream into a circular
loop through the biotechnological conversion into
valuable biopolymer.
