About the Company

Spiber Inc. is a Japanese biotechnology company developing synthetic spider silk without the use of animals or petroleum resources. The company is currently constructing the world’s largest structural protein fermentation facility in Thailand. With this expansion, Spiber aims to manufacture sustainable protein-based materials at a competitive cost. Commercial production of synthetic spider silk is expected to start in 2021, with a production capacity of several hundred tons per year.

Material

Brewed Protein™ is the company’s sustainable material inspired by spider silk and produced via fermentation.

Technology

Brewed Protein™ is produced using Spiber’s proprietary process. The code for the desired protein is inserted into microorganisms. Using the necessary sugars and minerals, these microorganisms grow this protein in a bioreactor. After fermentation is complete, the protein is purified and dried into a pellet or powder. It can then be processed and spun into fibers.

Applications

Spiber’s initial target industries are apparel and automotive.
