- Scientists at the University of Copenhagen have developed a bioplastic made from barley starch and sugar beet waste that decomposes fully within two months.
- This bioplastic is stronger, water-resistant, and truly biodegradable, addressing the limitations of current bioplastics that often fail to break down easily in nature.
- Researchers are working on prototypes for various applications, including packaging and automotive materials, with the goal of making these biodegradable alternatives widely available in the next 1-5 years.
Bioplastic Decomposes in Just Two Months: A Game-Changer for Plastic Waste
Researchers at the University of Copenhagen have achieved a significant milestone in environmental science by developing a bioplastic that decomposes in just two months.
This breakthrough offers a promising solution to the global plastic waste crisis. Unlike traditional plastics, which can linger for centuries, this new bioplastic breaks down completely and rapidly.
Derived from barley starch and sugar beet waste, the innovative material combines strength, water resistance, and full biodegradability. Professor Andreas Blennow, the lead researcher, highlighted the pressing issue of plastic waste that current recycling methods cannot fully address.
“We face an enormous waste problem that recycling alone can’t solve,” said Professor Blennow.
“Our new bioplastic is not only stronger and more water-resistant than existing options but also fully biodegradable. If it ends up in the environment, it can be converted into compost by microorganisms.”
Plastic pollution is a severe environmental issue. According to The Washington Post, there are about 21,000 pieces of plastic in the oceans for every person on Earth.
MIT research reveals that only 9% of global plastic is recycled, with much of it being incinerated. Traditional plastics can take between 20 to 500 years to decompose, according to the UN.
The Copenhagen team’s bioplastic stands out by fulfilling the promise of true biodegradability, a standard many bioplastics fail to meet. Professor Blennow criticized the term “bioplastic” for its inadequacy, noting that many such materials do not decompose easily in nature.
Microplastics, which have been found in human blood, contribute significantly to the pollution problem. Their health effects, including potential risks like lung inflammation and cancer, are still being studied.
The new bioplastic utilizes amylose, a starch component, and cellulose from sugar beet fibers. This combination produces a durable, flexible material.
The barley used is pure amylose-abundant, which prevents it from turning into paste upon contact with water. Sugar beet fibers add strength, making the material suitable for various uses.
Blennow envisions the bioplastic being applied to shopping bags and product packaging, replacing traditional plastics.
The team is also working on prototypes for food containers and exploring applications in the automotive industry.
“The technology is nearing the stage where we can start producing prototypes with companies,” Blennow said.
“I believe we will see different prototypes for packaging—such as trays, bottles, and bags—developed within one to five years.”
In the meantime, consumers can help by switching from disposable plastic bottles and bags to reusable alternatives, potentially saving $260 annually on bottled water by opting for a $40 reusable bottle.
This advancement joins other promising solutions, like Cove’s biodegradable bottle, in the fight against plastic pollution.
