Scientists turn coffee waste into biodegradable packaging to reduce landfill and extend food shelf life.
Researchers from Oregon State University and South Korea have developed a method to convert spent coffee grounds into biodegradable food packaging, potentially extending product shelf life.
This process, involving ethanol pretreatment and peracetic acid treatment, transforms waste into eco-friendly materials, reducing landfill waste and methane emissions.
The materials can be used in various packaging applications, but further research is needed to improve their resistance to light, moisture, and oxygen.
