Scientists from Tomas Bata University's Faculty of Technology and the Centre for Polymer Systems have pioneered a method to convert mixed plastic waste into electricity through mechanical-electrical conversion. By grinding, melting, and pressing various plastics such as PET bottles and food trays into thin films, they have created nanogenerators capable of producing electricity when subjected to pressure, friction, or heat. This approach offers a simpler and more environmentally friendly alternative to traditional methods that often involve energy-intensive processes. The team achieved the highest efficiency with films containing 60% PET material under frictional conditions. While the generated power is modest, it is sufficient to power small electronic devices like sensors or components of smart clothing. Notably, the mixed plastic waste, typically challenging to recycle, demonstrated higher electrical efficiency than individual plastic types, turning a recycling obstacle into an advantage for energy generation. This technology also provides an eco-friendly alternative to fluoropolymers, which are increasingly restricted due to environmental and health concerns. The research, ongoing for three years, is now part of a key project initiated in April 2025.
