TM as a bioreactor is a valid alternative to traditional PHA recovery systems with the advantage of obtaining, in addition to highly pure PHA, protein biomass and rearing waste from which to produce fertilisers, chitin/chitosan, biochar and biodiesel. TM-based plastic degradation is improved by co-feeding with food loss and waste as a dietary energy source, thus valorising these low-value substrates in a circular economy perspective. However, TM microbiota is recognised as a source of plastic-degrading microorganisms. TM’s use for plastic pollution management is controversial. PHA) from plastic-producing microorganisms, exploiting its highly diversified gut microbiota. In this review, we focus our attention on Tenebrio molitor (TM) as a valuable solution for plastic biodegradation and biological recovery of new biopolymers (e.g. Research is moving, on the one hand, to implement sustainable systems for plastic waste management and on the other to find new non-fossil-based plastics such as polyhydroxyalkanoates (PHAs). The plastics represent a great opportunity in the circular perspective of their reuse and recycling.
The increase in the world population leads to rising demand and consumption of plastic raw materials only a small percentage of plastics is recovered and recycled, increasing the quantity of waste released into the environment and losing its economic value.
