Abstract
Metal ions, such as Fe +3 , Mn +2 and Co +2 , are present in the formulations of pro-degrading additives and represent a means to accelerate the degradation of post-consumer plastics. When incorporated into the polymer, the pro- degradant additive serves to accelerate the degradation of the polymeric chain through oxidation initiated by light and/or heat, favouring the action of microorganisms. However, the consequences of the disposal of waste containing polymeric pro-oxidants are not yet known and represent an important area of investigation for environmental technology. In this work, we analysed the growth of the edible fungus Pleurotus sajor-caju and its ability to biosorb metals in culture media containing polyethylene films with and without a pro-degradant additive. In biosorption process metals, there is a contribution from the pro-degradant additive to the development of mushrooms from P. sajor-caju on different substrates. P. sajor-caju was effective in removing the following metals: Al, Ca, Cu, Fe, Mg, Mn, K, Na and Zn that were present in the pro-degradant additive and the masterbatch
