Biodegradable Tapioca Starch-based Bioplastic Film to Reduce Food Waste


A new that could help India manage its chronic food waste has been developed using tapioca starch previously destined for flushing into India’s rivers.

Scientists from the UK and India have developed a bioplastic film that is both significantly cheaper than current films and recycles waste starch produced by the country’s sprawling cassava plant industry.

Reducing Food Wastage with Extended Shelf Life
It’s hoped the new bioplastic can be used to extend the shelf-life of food in the country and help it reduce the amount of food that goes to waste.

“In India, cassava is used extensively in the diet of large sections of the society. But the cassava plant has to be first treated with washing and beating before it can be used,” said Professor Karnik Tarverdi, director of extrusion technology at the Wolfson Centre for Materials Processing in Brunel University London’s chemical engineering department, who worked alongside project leads Nextek and colleagues from the University of Greenwich.

“When the plant is treated, it releases tapioca starch that is washed down the waterways and causes pollution downstream. We wanted to harness the waste starch and use it as an additive to make film cheaper.”

New Product Similar to Standard Food-grade Plastic Film
The film, which took two years to develop and was funded by the Innovate UK's Newton Fund, contains 30% tapioca starch and has the same properties as . Whilst the product isn’t yet commercially available, the lower cost of the raw materials used to make the new film makes it feasible for more farmers and producers to wrap their fresh produce.

The researchers will now pass their work on to their Indian partners, who are setting up a new manufacturing plant to replicate and demonstrate the new film at a much larger scale.
