Study Validates Biodegradation of Compostable Bioplastics

A Sustainable Solution for Managing Waste in the Food Packaging Industry

In a recent study conducted by researchers from Chaire CoPack, AgroParisTech, and the University of Montpellier, compostable bioplastics have been proven to successfully biodegrade in industrial composting facilities. The study aimed to validate the effectiveness of certified compostable food contact packaging as a sustainable solution for waste management in the food packaging industry.

The researchers performed a comprehensive four-month composting test using 20 tonnes of food waste and bio-waste collected from households, along with 323kg of certified compostable packaging. The composting process took place in an industrial composting facility provided by Syndicat de Centre Héraut in Aspiran. A control compost test was also conducted without the addition of packaging for comparison.

The study evaluated commercially available food packaging products from the European market, including food trays, compostable bags, films, and coffee pods. These products were made from biodegradable and compostable resins such as polylactic acid (PLA), polybutylene adipate terephthalate (PBAT), and complexed starch. The materials were sourced from members of the French Association of Biobased Compostables, including TotalEnergies Corbion and Novamont.

Throughout the composting process, the researchers monitored the biodegradation progress through regular checks and sample collection. The test results demonstrated that the addition of certified compostable packaging positively influenced the composting yield. Moreover, the tested materials met the decay rate requirements of compostability standards, confirming their successful biodegradation. This finding provides strong evidence to support the use of compostable bioplastics as a sustainable alternative for food packaging.

The findings of this study have significant implications for waste management in the food packaging industry. The successful biodegradation of certified compostable packaging validates its integration into biowaste collection and composting infrastructure. Governments are encouraged to recognize the environmental benefits of compostable packaging and develop supportive policies and regulations to facilitate its widespread adoption.

Compostable bioplastics offer several environmental benefits compared to traditional plastics. By reducing reliance on fossil fuels, they contribute to lower carbon emissions and help mitigate plastic pollution. However, challenges such as standardized labeling and public awareness regarding proper disposal practices need to be addressed. Collaboration among stakeholders along the value chain is crucial for the successful implementation of compostable packaging and waste management strategies.

In conclusion, the study validates the biodegradability of compostable bioplastics in industrial composting facilities, supporting their use as a sustainable solution for managing waste in the food packaging industry. By embracing compostable packaging and implementing sustainable waste management practices, we can significantly reduce plastic waste, lower carbon emissions, and create a healthier planet for future generations. It is essential for governments, businesses, and consumers to work together towards a more circular and environmentally conscious economy.
