The current textile world is loaded with synthetic materials produced through the union of petroleum and
chemistry. These aseptic materials have already caused significant damage to nature. While everyone is looking for a sustainable and carbon-neutralized textile manufacturing solution, Spiber’s Brewed Protein™ may be the exact solution.
This bio-degradable protein polymer is synthesized from a plant-based origin by a microbial fermentation process and spun into different quality yarns to produce variety of fabrics. It is expected that this ISO-certified Brewed Protein™ fiber’s quality and sustainable properties can help people to make new, creative, and powerful choices over animal protein-based fibers such as cashmere, silk, and
wool protein polymer production.
How it’s made?
15 years of research and studies, paved the way for Spiber to synthesize protein-based polymer through
microbial fermentation of plant-based ingredients. Currently, they are using Bonsucro-certified sugar extracted from renewable agricultural sources like sugarcane or corn as their initial raw materials. Their innovative lab work has enabled them to alter the DNA structure followed by fermentation (brewing) of sugar which generates specialized protein polymer Brewed Protein™ with enchanting properties
and qualities. Once the fermentation is done, the polymer is then extracted and undergoes several treatments to achieve the required qualities and characteristics. It is completely biodegradable in soil as well as in seawater.
Though the protein evolution requires millions of years, Spiber’s cutting-edge lab technology reduced the time to a year or even a month and made it possible for industrial applications.
Contribution Towards Sustainability
Textile manufacturing process using Brewed Protein™ polymer shows impressive features such as reduced greenhouse gas emission by up to 79%, eutrophication by up to 82%, land use by up to 99%, and water use by up to 97% (According to LCA study).
Spiber’s Prospects And Goals
1. Future Prospects and Goals
As a leader in sustainable materials, Spiber sees Brewed Protein™ revolutionizing the textile industry.Their lofty objectives consist of:
Net Zero Carbon Footprint: Spiber wants to attain net zero greenhouse gas emissions from the textile industry by the year 2035.
Circularity: By reusing and recycling textiles and clothing made of biobased materials, Spiber hopes to complete the circle. Used textiles (think rayon, cotton, and linen) will be transformed into nutrients for their microbial fermentation process
2. Industrial Production and Significance
Current Volume: Spiber is starting to produce Brewed Protein™ on an industrial scale. Similar to cashmere and silk, their fibers are being used in denim, filament yarns, and staple fibers. They have already taken a vision to produce 1000T in 2025.
Importance: Sustainability is the key to importance. Brewed Protein™ is not dependent on petrochemicals or animals, in contrast to conventional materials. It contributes to cleaner
oceans, lessens land use, and uses less water.
