Plastic and plastic recycling/degradation has been in the spotlight during last decade, due to its increasing waste accumulation in all world’s ecosystems and the huge challenge deriving from micro-plastic pollution. Therefore, different strategies are under investigation, trying to cope with this problem. Although depolymerisation of plastics by chemico-physical methods seems to represent a promising technology, biodegradation by microorganisms has been raising interest in recent years. In fact, new studies regarding the possibility of engineering specific plastic-degrading enzymes have obtained much attention by the media, due to the hope of overcoming one of the main bottlenecks of this technology: the extremely slow conversion rates. In the following chapter, we will be discussing two important strategies, which are expected to help overcoming these bottlenecks: genetic engineering to improve the catalytic activity of plastic-degrading enzymes and the development of syntrophism and cross-feeding mechanisms in enriched microbial communities. Finally, the potential of ongoing studies and future trends will also be discussed.
