New environmental and social challenges demand new solutions. Algae grows in seawater and so reduces the pressure on land and fresh water in the production of agricultural crops. Redrose Developments is liaising with local, national and international agencies doing research into the sustainable development of seaweeds and related maritime species. 


Many people have been involved in invaluable research and development  into the use of seaweed in Ireland: our ancestors who first realised it was possible to eat seaweed; their decendants who continued to experiment with how to use seaweed; harvesters who have shared their knowledge and produce with others over time and people like Professor Micheal Guiry who created Algaebase and Dr Prannie Rhatigan who wrote The Irish Seaweed Kitchen.


Still more research is needed to understand new ways of developing algae without having detrimental effects on their ecological relationships with their environments and other species. We are working with the Ryan Institute, reviewing the practicality and commercial potential of new methods of growing a range of sea plant species in scale-able quantities. We are establishing innovation partnerships with universities to explore processing systems to extract value from various sea plants.


Product innovation is occurring all the time. As our understanding of the potential of seaweed increases, we aim to create a range of opportunities based on using the validated outputs from the processing of seaweed into tangible and marketable seaweed based products.  Seaweeds produce nutrients and organic material for use in the food, bio-medical and agricultural industries and more.


We support the spirit of innovation and the responsible and sustainable development of our natural resources.
