OUR BUSINESS
From wild Atlantic shores to thriving fields.
Farmers face harsher climates, scarcer resources and rising demand for food. C-BIO applies scientific innovation to deliver greater yields of healthier food with sustainability at the core.
Hand harvested in Donegal
At low tide, experienced harvesters cut Ascophyllum nodosum with a serrated sickle, leaving 12–20 cm attached to the rock so it regrows naturally.
