Abstract

Synthetic polymers are hazardous to the environment mainly in the marine environment as a lot of plastic wastes end up in the saline waters especially in the estuaries. Synthetic polymers obtained from plastic bottle wastes and polymethyl methacrylate (PMMA) are known to be non-biodegradable. In order to obtain biodegradability, polymers are reinforced with bio-fillers. Biodegradation is a convenient tool to degrade the synthetic polymers and bio-filler reinforcements increases the biodegradability of these polymers. Fungi are known to degrade organic materials and have developed adaptability to procure hard carbon sources. In this study, fungi isolated from the Sundarban areas (three types of Aspergillus sp.) have been used to biodegrade plastic bottle waste strips, PMMA and PMMA/cellulose composites. These polymer composite films were found to be degraded by the micro-organisms as ascertained by their weight loss analysis. The PMMA/cellulose composites lost 24% of its weight after 6 weeks by Aspergillus sp2, whereas the PMMA lost 16% of its weight by Aspergillus sp3. The plastic bottle waste lost about 20% of its weight after 6 weeks as a result of degradation by Aspergillus sp 1. Thus, these marine micro-organisms were found to degrade the polymer and polymer composites.
