Most individuals often discard their leftover coffee grounds without much consideration, yet these grounds could serve as a simple solution to a common issue. While many turn to store-bought products for household problems, experts suggest that the remedy to a smelly fridge might be found in what is typically thrown away.
If you encounter unpleasant odors in your fridge, a solution may already exist in your kitchen, as shared in a viral TikTok video by Neighbourhood Coffee Roasters in Liverpool. The video showcases five creative ways to repurpose used coffee grounds instead of disposing of them.
In the video, a woman demonstrates placing a small cup of old coffee grounds in the fridge to combat lingering odors from foods like cheese, fish, or leftovers. This method involves placing the used grounds in an open container and leaving them inside the fridge.
According to experts, there is scientific reasoning behind this idea. Used coffee grounds contain nitrogen and porous organic compounds that can absorb and trap odor molecules akin to baking soda, as detailed in research from Food Science and Technology.
This natural deodorizing action of coffee grounds can help neutralize bad smells instead of just masking them. Sustainability specialists explain that the porous structure of spent coffee grounds allows them to absorb specific compounds in the air that cause unpleasant odors.
Moreover, this trick could aid in addressing a growing waste issue. The UK alone generates over 500,000 tonnes of coffee ground waste annually, with a significant portion ending up in landfills, potentially emitting methane, a potent greenhouse gas.
On a global scale, millions of tonnes of used coffee grounds are discarded each year worldwide, despite containing valuable nutrients and compounds. Neighbourhood Coffee’s video also suggests other unconventional uses for coffee grounds, such as adding them to compost for enriching the soil and supporting plant growth.
These grounds can serve as a natural fertilizer for certain plants, enhancing soil quality due to their mineral and organic compound content. Additionally, they can be used as a gentle cleaning scrub for surfaces or incorporated into homemade skincare scrubs for exfoliation.
Next time you brew your morning coffee, consider the potential of your leftover grounds before disposing of them. That simple act could help maintain a fresh-smelling fridge while contributing to waste reduction efforts.
