Optimization Study of the Bio-Plastic Formula at Bio-Zmzm Company: Effect of Oxo-additives Content on Degradation, Thermal and Mechanical Properties

Abstract

The interest in environmental issues is growing and there are increasing demands to use of polymers that degrade more quickly than conventional plastics. Recent work aims to do a scientific research for a Bio-Zmzm company in Hebron. The study discusses subjects of bioplastic and non-biodegradable plastic. The basic principles of project are an optimization study of the existing formula of bioplastic product at Bio-Zmzm through the use of oxo-additive chemicals to determine the effect of Oxo additive content on degradation, thermal and mechanical properties. Also to improve the ability of plastic to become biodegradable. The experiments were carried out on several samples of plastic bags and packaging films. The samples were produced by changing the mass percent of additives, but percentage of other components (polyethylene (PE), glue, CaCO3, pigment) remain constant. Mechanical tests include each of the free fall test and adhesion test were carried out. The results showed that changing the mass percent of additives (either increase or decrease) did not affect the mechanical properties (durability, Fragility) of product. However, after the tensile and TGA test showed that the highest decomposition rate was for most samples for 2.5974% of oxo- additives. This indicates an increase in the ratio of oxo- additives lead to increases the rate of degradation. Also the marl stone had the highest rates of decomposition. This indicates that it is the best medium and environment for plastic decomposition.
