Abstract
Biodegradation of the bioplastic composite based on cellulose from oil palm empty fruit bunches was investigated in this study. Microbes consortium from landfill soil collected from top soil were used as the inoculums for the biodegradation process. Biodegradation test of the bioplastic from oil palm empty fruit bunch samples compared with oxodegradation and conventional plastic samples were conducted in the glass jar. The biodegradation rate was evaluated from CO2 generated from the biodegradation process and absorbed by 0.1 N sodium hydroxide solutions. The generated CO2 was titrated with 0.1 N HCl and using phenolphthalein (PP) followed by methyl oranges indicator. The results showed that the highest CO2 production on landfill soil indicating the highest rate of biodegradation was found on bioplastic from oil palm empty fruit bunch followed by oxodegradable plastic and conventional plastic. The rate of biodegradation for bioplastic from oil palm empty fruit bunch, oxodegradable plastic and conventional plastic were 0.067mg CO2/day, 0.052 mg CO2/day and 0 mg CO2/day, respectively.
Highlights
Plastic are widely used as packaging and many other applications and continues to increase
The purpose of this research is to evaluate the bio-degradability of bioplastics made from oil palm empty fruit bunch in natural environment, and compare it with biodegradability of oxodegradable plastic and conventional plastic
The metabolic activity of microorganisms will produce CO2 flowing from bottle B to bottle A and catch by NaOH
Summary
Plastic are widely used as packaging and many other applications and continues to increase. Within the different plastic applications, plastic packaging reached the highest recycling rate (39.5%) and repre-sented more than 80% of the total recycled quantities (Plastics Europe 2015) This statistic highlights the need for a renewable, all natural replacement for pe-troleum based plastics (DiGregorio 2009). Waste that accumulates in river can cause and interfere the river flow, so the floods occur, for human, smoke from plastics burning waste can trigger cancer, respiratory problems, nerv-ous system disorders, and hepatitis. The purpose of this research is to evaluate the bio-degradability of bioplastics made from oil palm empty fruit bunch in natural environment, and compare it with biodegradability of oxodegradable plastic and conventional plastic.
