Abstract

In this study, a cassava starch/low-density polyethene (LDPE) blend was compounded and the effect of this starch pretreatment on the rate of degradation of synthetic polyethene carrier bags was tested using bacteria and fungi (as singles and as consortia) isolated from dumpsites.

Weight loss and Fourier Transformed Infra-Red Spectroscopy (FTIR) were used as analytical techniques for measuring biodegradation. Fungi were found to degrade both synthetic LDPE and LDPE/Starch blend resulting in a weight loss of 3.54% to 19.68% while that obtained from bacteria gave a weight loss of 1.0% to 18.5% within 30days.

Mixed cultures comprising of both bacteria and fungi gave better results than the individual organisms and the addition of starch was found to greatly enhance the biodegradation of the low-density polyethene carrier bags.

Introduction

One of the most common items in our modern world is the ubiquitous plastic shopping bag which is made out of polyethene.

Polyethene is a member of a large family of polymers called thermoplastic polymers. It consists of long chains of the monomer ethene with its 2CH₂ groups connected by a double bond, (H₂C=CH₂)  (Nanda et al., 2010).

Polyethene, a waxy chemically inert plastic, is one of the simplest and most inexpensive polymers. It contains the chemical elements, Carbon and Hydrogen, (Suseela and Toppo, 2007; Ramesh and Pramila, 2011).
