Waste Vegetable Oil: Cheap Raw Materials Bioplastics

Bioplastics which is naturally synthesized by microbes can be made into commercial use waste vegetable oil as a starting material (starter). This will reduce environmental contamination and also provides a high quality plastic that is suitable for medical implants, according to scientists presenting their research findings at the Society for General Microbiology’s Autumn Conference at the University of Warwick.

Polyhydroxyalkanoate (PHA – family polyster) were synthesized by a variety of bacteria as a source of energy as much carbon stocks. Poly3-hydroxybutyrate (PHB) is the most widely produced polymer PHA family. Currently, bioplastics growing bacteria in a fermenter large amounts need not cost less because glucose is used as a starter.

Research conducted by a team of researchers at the University of Wolverhampton recommend using waste vegetable oil as a starting material to reduce the production cost of plastic. “Bioplastic-producing bacteria, Ralstonia eutropa H16, grow better on oil for more than 48 hours and therefore produce three times more PHB than when the bacteria are grown in glucose,” explained Victor Irorere who conducted the study. “Electrospinning experiments carried out in collaboration with researchers from the University of Birmingham, showed that the nano-fiber plastics are produced from oil berkristal too little, which means the plastic is suitable for medical applications.

Previous studies have shown that PHB is an attractive polymer for use as microcapsules for effective delivery of therapeutic drugs and medical implants, due to the nature biodegrabilitas and non-toxic. PHB quality improvement combined with low production costs will allow PHB used more widely.

Waste plastics used – mostly non-biodegradable is a major environmental issue, the plastic waste in the UK coast have risen over the past two decades and now accounts for about 60% of marine debris. “The use of biodegradable plastics such as PHB encourage reducing environmental contamination. Unfortunately, the cost of glucose as the starting material has been hampered by the commercialization of bioplastics, but also reduces the environmental contamination caused by waste vegetable oil. “
