May 23 (Bloomberg) -- Researchers at the University of Cordoba and the University of Girona, Spain, have developed a promising solution using avocado pruning waste. The study, published in the journal Advanced Sustainable Systems, successfully isolated fibers from avocado prunings and blended them with a special type of bioplastic to create a composite material. The new material has the potential to replace some of the non-biodegradable plastics currently used for rigid food packaging.
The process involves converting the natural fiber cellulose in the plant from avocado residue into a powerful reinforcing material. This material can be used to create packaging that is more sustainable and stronger than traditional bioplastics such as bio-polyethylene.
Research has shown that avocado-based composites offer some improvements over traditional bioplastics. It is stiffer and has a stronger bond between the fibers and the plastic. However, the avocado fibers themselves are not as strong as some other plant fibers used in similar applications.
This is a promising initial study, but further research is needed. Scientists need to evaluate how well the new material performs on key factors, such as migration (leaching of chemicals into food), water resistance and overall cost-effectiveness. In addition, a complete life cycle assessment would be valuable in understanding the environmental impact of this new approach.
