A new study in the United Kingdom says that a bacteria can turn waste cooking oil into bioplastics with higher efficiency. If it can be used for large-scale industrial production, it can reduce the cost of bioplastics and help solve the problem of “ditch oilâ€. problem.
Bioplastics are polymers produced by natural substances such as starch under the action of microorganisms. Their performance is similar to that of traditional chemical plastics. It also has the advantages of biodegradability and environmental protection. The polymer referred to as PHB is a commonly used bioplastic, but now its raw material is usually glucose, which has high cost.
At the fall academic meeting of the British General Microbiology Society, researchers at the University of Wolverhampton reported that a bacteria named "Ralstonia strain H16" can use oils and fats to produce PHB bioplastics. Experiments have shown that this bacterium grows better in oil than in glucose, and PHB yield is several times that of traditional methods.
Iza Radka, who led the study, said that the use of glucose as a raw material has resulted in a higher cost of PHB. This study shows that waste edible oil can also be used to make PHB. In addition to cost advantages, the new method also helps resolve waste cooking oil issues. The researchers said that the next step will be to explore how to use this method to mass produce industrial bioplastics. (Reporter Huang Hao)
