Bio Materials: Making Seaweed Plastic

From foraged seaweed to bioplastic with a purpose.

Key details

Location

Falmouth Campus

Course duration

1 day

Course overview

Join us for this one-day practical introduction to bio-materials in the fashion industry. Seaweed is an exciting prospect as an alternative to many of our currently used petro-plastic fibres and is increasingly being explored as an alternative, sustainable, material.

We'll learn about seaweed types and preparation methods then make several bio-plastic samples, experimenting with different methods and ingredients to create a collection of bio-material plastics to take home.

Tuition fees per individual: £150

Location: Open Access Workshop, Falmouth Campus

Course details

This is a one day practical and fun introduction to sustainable bio-materials and their potential uses in fashion. With micro-plastics in our oceans, and unwanted clothing swamping our landfills there is a current and much-needed focus on exploring alternatives to petro-plastic fibres such as polyester, which are consistently used in the fashion industry and more widely.  

Seaweed is a locally available resource, has exciting properties that can produce biodegradable plastics, and has the potential to provide an alternative answer for our fashion industry with several fashion brands currently exploring this.

Over the course of this day, you’ll be taken on a journey from seaweed and various food waste products, through to finished bioplastics that have a purpose. 

You’ll learn about the seaweed that can be found along our shores, discussing the different types of polysaccharides that are useful to make bio-plastics.

We’ll discuss the process to turn fresh seaweed into bio-plastic, as well as other readily available food-waste materials.

There will be an option to forage in our gardens for materials to use to decorate your bioplastics.

You’ll then experiment with different methods to create several sample bioplastic sheets both from seaweed and from other materials, that you’ll colour using eco-pigments. These will be dried out for you to use after the course. You can either take them home with you as they are, or we’ll post them to you once they have dried.

This one day course will cover:

Learning about biomaterial composition and circular economy integration.
Reviewing different types of seaweed, learning about the different types of polysaccharides that are useful to make bioplastics.
Learning about practical techniques for turning materials such as seaweed and food waste products into biomaterials that can be used for fashion or products.
Experimenting with methods to make bioplastics, using the techniques you have learned to create several sheets of samples and with the option to colour them using eco pigments and decorate them with foraged materials from our campus gardens.

You will leave with:

Ideas about how you might start to include biomaterials in your own practice or business.
The collection of samples that you have made (once they have dried).

Alice Selwood

Alice Selwood is a Senior Technician at our Fashion and Textiles Institute who specialises in sustainability, natural dye, and textile design. Inspired by strong organic and structural forms, sustainability is key to her design process. Alice pushes the boundaries of traditional natural dyeing within her textile work, embracing the wide variety of colours nature can provide. Through her post-graduate research, she has been developing alternative bio-plastics through natural materials including seaweed and food waste.  Alongside this, Alice works commercially as a textile designer creating elegantly detailed embroidery and embellishment for luxury fashion and interiors. 

How you'll learn

This is a practical course where you will get hands-on experience of making your own bio-plastics from seaweed. Expect to get involved at every step of the process, as Alice guides you through with demonstrations and support.
