Oyster farms in Ireland have been found to remove 228% more nutrients than they produce, providing coastal cleanup worth $2 million. The farms studied bound the equivalent of almost 275 kilos of CO2 in their shells, offsetting the carbon impacts of their lifecycle by 73%. And the bivalves soaked up the equivalent of 2.36 kilograms of phosphorus per ton (which included nitrogen and phosphorus in one figure). That’s roughly six-fold—or 228% more—than the nutrient pollution they generate.
