Many bio-plastic bags have no place in the garbage. They dissolve too slowly in oxygen-deficient environments like biogas plants and when incinerated they are a burden to the environment. Enzymes offer a solution to this problem, accelerating degradation and avoid emissions. In the long run, the aim is to reduce plastic mountains and replace conventional packaging by bio-based Polymers.
Complex, recalcitrant polymers represent a barrier in the biodegradation process during anaerobic digestion (AD) towards biogas production. This concerns both, biopolymers from plant waste as well as synthetic polymeric plastics entering biogas plants as packaging material with food waste. Therefore, microbial populations and their enzymes involved in the hydrolysis of lignocellulose-rich plant material and modified polyesters are investigated to develop a strategy to biologically boost the conversion of waste to bioenergy by tailor-made microbial communities and bioaugmentation.
