Textiles from Seaweed and Marine Waste Course
This course prepares you to understand and apply new textile fibers of marine origin. You will study fibers obtained from seaweed, such as alginate and cellulose fibers, marine-derived dyes and finishes, the recycling of fishing nets and plastics recovered from the sea into polyamide and polyester, and the traceability, certification and communication criteria that prevent greenwashing in fashion and technical textiles.

What is the Textiles from Seaweed and Marine Waste Course?
This short course explores the two main routes for turning the sea into textiles. You will review natural, man-made and synthetic fibers, the impacts of the textile industry and microfibre pollution; learn how alginate and seaweed cellulose fibers are spun, blended and scaled up; follow the recovery of end-of-life fishing nets, polyamide depolymerisation and polyester from recovered plastics; look at marine pigments, functional finishes, collections and technical and sportswear; and examine recycled-content certification, life cycle analysis, environmental claims and business models.
What sets this course apart: fashion and innovation, with new fibers for a sector actively seeking alternatives; two complementary routes, seaweed biomass and recycled marine waste; a view of the complete chain from raw material to textile product; responsible communication based on traceability and rigorous environmental claims; and a practical case in which you develop a concept for a marine textile product.
Program highlights

Questions about the Textiles from Seaweed and Marine Waste Course
Commercial fibers and blends exist, mostly in niche markets; large-scale production is still being developed.
They reduce waste but remain synthetic; the course analyses their pros and cons.
Yes. The release of microfibres and how to reduce it are studied.
No. The course starts from the basic concepts.
You develop a concept for a textile product made with marine materials, including traceability and communication.
Fully online, through a virtual campus available 24/7, with live sessions that are recorded and tutorials with the teaching staff.
The course comprises 300 hours of study across 5 modules of about 60 hours each and ends with an applied practical case. You can progress at your own pace within the schedule set when you enroll.
