New Method Helps Cut Costs and Wastage in Bioplastic Production
 
A team of researchers at the KU Leuven Centre for Surface Chemistry and Catalysis has formulated a simple method to produce the bioplastic known as polylactic acid (PLA) in a waste-free manner.

PLA bioplastics are employed in several products used in daily life such as vegetable wrapping foil and biodegradable drinking cups. However, so far, they are not thought of as a 100% alternative to conventional petroleum-based plastics as they cost more to produce.
 
Basically, PLA bioplastics are obtained from renewable resources such as sugar found in sugarcane and maize. The sugar turns into lactic acid upon fermentation. The lactic acid then acts as a building block for polylactic acid. Over a period of time, exposure to certain environments causes the PLA to degrade.
 
However, this can still be put to use if properly collected and sorted, as this plastic is industrially compostable as well as recyclable. Another key feature of PLA plastics is that they are biocompatible, therefore can be applied in the medical sector to make several products such as absorbable suture threads. These bioplastics can also be adapted for use in 3D printing.
 
Despite these advantages, PLA is still not being used as an alternative to petroleum-based plastics due to the intermediary steps, which increase the overall production costs.
 
Going forward Professor Sels believes that the novel technology is very likely to make an impact. ¡°The KU Leuven patent on our discovery was recently sold to a chemical company that intends to apply the production process on an industrial scale. Of course, PLA will never fully replace petroleum-based plastics. For one thing, some objects, such as toilet drain pipes, are not meant to be biodegradable. And it is not our intention to promote disposable plastic. But products made of PLA can now become cheaper and greener. Our method is a great example of how the chemical industry and biotechnology can join forces¡±.
 
The team¡¯s research findings were published in Science.
