Sustainable Seaweed
Red Seaweed Promise™ - leading the industry towards a thriving red seaweed sector for generations to come.
To help ensure a long-term sustainable red seaweed supply chain, Cargill has launched the Red Seaweed Promise™. The program is specifically designed to address key sustainability challenges for the harvesting and cultivation of red seaweed, while enhancing producer livelihoods, supporting local communities and conserving the marine environment. Red seaweed is the raw material needed to produce carrageenan, a texturizer used in various applications such as dairy, confectionary and personal care products.
The program also answers food industry and consumers’ needs for more sustainable food ingredients, with a commitment to source 60 percent sustainable red seaweed by 2025.
Sustainable Seaweed Commitment
It is our ambition to enable seaweed producers and their communities to achieve better incomes and living standards in a way that will accelerate progress towards a sustainable and transparent global seaweed supply chain by focusing our investments and efforts across four priority areas.

Provide training, coaching and tools to support best environmental, and safe production practices.
Strengthen Partnerships
Leverage Cargill's network to strengthen the close partnerships with suppliers to achieve a sustainable red seaweed supply chain.
Improving production and harvesting practices

Community Support

Continuous Improvement
To reaffirm our long term commitment to red seaweed producers and their communities specific continuous improvement action plans are developed specifically matching the regions where Cargill sources.
