Result description

Biodegradation potential and specificity towards polyethylene (PE; and its variants Low Density PE - LDPE - and Linear Low Density PE - LLDPE), polypropylene (PP), polyvinyl chloride (PVC) and polystyrene (PS) plastic films and their additives by newly enriched/isolated, naturally-occurring bacteria and fungi obtained from plastic waste from landfills, industrial sites, composting and anaerobic digestion facilities as well as from the Aegean and the Northern seas.

Result description

Degradation mechanisms and potential towards polyethylene (PE; and its variants Low Density PE - LDPE - and Linear Low Density PE - LLDPE), polypropylene (PP), polyvinyl chloride (PVC) and polystyrene (PS) plastic films and their additives by newly enriched/isolated, naturally-occurring bacteria and fungi obtained from plastic waste coming from landfills, industrial sites, composting and anaerobic digestion facilities as well as from the Aegean and the Northern seas. The mineralization of PS by Penicillium variabile was demonstrated using 14C-labelled PS.

Result description

Pilot-scale biological or hybrid chemical/physical-biological processes for the degradation of polyethylene (PE; and its variants Low Density PE - LDPE - and Linear Low Density PE - LLDPE), polypropylene (PP), polyvinyl chloride (PVC) and polystyrene (PS) films. Remarkable biodegradation rate and extents were observed on PVC and, to less extents, on PE (LDPE, LLDPE) and PP plastic films.

Result description

Lab and pilot-scale bioaugmentation protocols for intensifying (micro) plastics biodegradation in soils, composting/anaerobic waste treatment facilities and marine environments. Some protocols displayed limited or no bioremediation enhancements but the protocols developed for assessing the activity deserve scientific and technological interest.
