Spiber Inc., an innovative biomanufacturing startup based in Tsuruoka, Japan, has successfully raised over 10 billion Japanese yen in its latest funding round. This major influx of capital aims to support the company’s ambitious efforts to ramp up the mass production and enhance the global distribution of its Brewed Protein™ materials. Pioneering in both scope and concept, these advanced materials represent a significant stride towards more sustainable manufacturing practices and are gaining remarkable interest both from investors and the wider global market.

Established in September 2007, Spiber Inc. has spent more than 15 years meticulously refining its exclusive technology which culminates in an alternative category of material now recognized as protein fibre by the International Organization for Standardization (ISO). As defined under the recent ISO2076 standards revised in November 2021, protein fibre includes both naturally-derived and synthetically-produced protein, with the material required to consist of at least 80% protein. Spiber’s Brewed Protein™ is a vital development in this respect, meeting and surpassing these criteria.

The innovative process used by Spiber involves the synthesis of protein materials through a microbial fermentation process. Using plant-based raw ingredients, proteins are engineered at the DNA level and transformed into fibers, resins, films, among other forms, fitting a range of applications from textiles to packaging and beyond. This bespoke process is seen as a key driver for the future of sustainable materials — aligning closely with the increasing global demands for eco-friendly production alternatives.

The apparel industry, notorious for its substantial environmental footprint, has been a primary focus for the application of Brewed Protein™. The material’s versatility and sustainability have already piqued the interest of 15 major domestic and international apparel brands, indicating a promising adoption rate and potential for mass scalability.

The recent successful funding round, backed by stalwart investors, underscores a robust confidence in Spiber’s technology and prospects. Commenting on the investments, Kazuhide Sekiyama, Director and Representative Executive Officer of Spiber, expressed gratitude for the ongoing support from investors and partners who share the company’s vision for a biotechnological foundation capable of establishing a circular economy.

The drive towards circular economic models has escalated in importance within global discourse on environmental sustainability, particularly related to waste reduction and the sustainable use of resources. Spiber’s developments in Brewed Protein™ materials are well-aligned with these global initiatives, offering potential for revolutionary transformations in material science.

As Spiber continues to expand its production capabilities and explore new partnerships and markets, the wider implications for global industries and environmental health are immense. This development not only demonstrates the leaps being made in biotechnology but also heralds a future where sustainable materials are the norm, not the exception.
