Oyster Shells
95% Calcium carbonate
5% organic matrix proteins (shell proteins)
Oyster shells are largely composed of Calcium Carbonate, which is valuable and used in many industries. However, most of the shells become untreated waste, filling landfills and releasing methane, a harmful greenhouse gas.
Food waste | Impact
30%
28x
3rd
The global food system accounts for up to 30% of greenhouse gas emissions. And Around 6% of total global greenhouse gas emissions are caused by food wastage.
Our food system produces a significant amount of methane, which is 28 times more powerful than CO2 at warming the planet.
If “Food Waste” were a country, it would be the world’s 3rd largest emitter of CO2 after China and the US.
