Upcycling Mussel Shells Waste
Our sustainability efforts start with discarded green mussel shells collected from Chonburi Province, an area well known for its seafood-processing industry. This industry produces large amounts of seafood waste, including mussel shells. By speaking with local fishermen and seafood-processing communities, I learned that these shells often pile up, creating waste and unpleasant odors.
BeeFriend gives the shells a new purpose by transforming them into a useful ingredient. This helps reduce local waste while creating value for coastal communities.

Production Process
How BeeFriend Works?
BeeFriend uses Bio-Calcium Carbonate as a natural physical barrier against soft-bodied insects. It disrupts their movement and feeding, makes the treated surface less suitable for insects, and has a drying effect that dehydrates them.
Bees are less affected because their hairy bodies help prevent the fine powder from reaching sensitive areas. They also mainly visit flowers for nectar and pollen rather than spending time on treated plant surfaces. This allows BeeFriend to control unwanted insects while helping protect important pollinators.

Field Lab
To test BeeFriend’s effectiveness and safety for pollinators in a real-life setting, I conducted a trial in my own garden, where plants affected by mealybugs near my four active beehives.
After applying BeeFriend, I monitored both the plants and the bees closely. Within a few days, the mealybugs were eliminated while the bees remained unharmed.
At the same time, I closely monitored the bees visiting the flowers. Using a counting method inspired by the University of Minnesota’s Great Sunflower Project, I recorded bee activity before and after applying BeeFriend.
The number of visiting bees remained steady and even increased slightly, suggesting that BeeFriend controlled unwanted insects without harming the honeybees.
